The Garmin inReach Mini currently represents a “gold standard” for lightweight satellite messaging devices.
The category of satellite messaging devices includes products that are capable of the following core features:
- The ability to trigger an SOS signal to an emergency search-and-rescue network.
- The ability to send location/tracking/SMS messages to friends, family, or colleagues.
In addition, some of these devices are capable of two-way messaging (the ability to also receive messages from friends, family, colleagues, or search-and-rescue personnel).
The Garmin inReach Mini falls into this latter category – it’s a two-way satellite communications device and, at only 3.4 oz, represents one of the lightest available devices in this category. Arguably, the Garmin inReach Mini is probably the most feature-rich and powerful product when compared to all satellite communications devices that weigh less than 5 oz.
Review Rating: Highly Recommended + Guide’s Gear
The Garmin inReach Mini is the smallest, lightest, and most powerful satellite messaging device on the market.
As a standalone device, it offers GPS navigation, two-way messaging, location sharing, and weather forecast retrieval. Paired with a mobile device and the Earthmate app, the Garmin inReach Mini is a highly capable and easy-to-use mapping GPS with a much faster interface for managing and composing messages. The Garmin inReach Mini is tiny in size, light in weight (3.4 oz), durable, waterproof (IPX7), and features a very high-quality build.

I’ve been carrying a satellite communications device of one type or another since 2004 when ACR Electronics released the consumer-targeted Terrafix 406 personal locator beacon. Considering the 12-ounce weight and $640 price tag of that device, it’s safe to say that satellite communications devices have come a long way since then.
Since then, I’ve field-tested each of the following messaging devices on more than 100 multi-day backcountry trips:
- SPOT Messenger (Gen 1, Gen 2, and Gen 3)
- SPOT X
- DeLorme/Garmin inReach SE/SE+ and Explorer+
- GSat Micro
- Iridium NAL SHOUT Nano
In addition, I own and carry an Iridium 9575 Extreme satellite phone, which is my device-of-choice for trips where I’m guiding clients. It’s also what Backpacking Light issues to its guides for our Wilderness Adventures treks. The ability to communicate by voice directly with medical professionals for in-the-field consultation has proven to be an invaluable asset for guided trips.
Finally, I’ve rented and carried the Inmarsat iSatHub Terminal for satellite broadband use several times for photo and long-form live blogging from the backcountry.
Of these devices, the GSat Micro and Iridium NAL SHOUT Nano are best integrated with commercial OEM applications. The iSatHub Terminal is a highly-specialized (and heavy) broadband device that offers capabilities significantly beyond the needs of most recreational backcountry users. Likewise, these devices won’t be considered further in this review in the context of evaluating the market position and performance of the Garmin inReach Mini.
In addition to the devices listed above, a new consumer category of satellite devices is emerging. This category – satellite “hotspots” – is perhaps best represented by the not-yet-released Somewear Labs Global Hotspot, which (unlike devices from Spot and Garmin) requires a smartphone for messaging. The Somewear Hotspot reflects the continuing trend in this category towards miniaturization and smartphone integration. SPOT released a similar device called the Connect in 2011 but met with terrific resistance among users due to its inability to pair with seemed like half the phones on the planet. The SPOT Connect has been discontinued.
Worth noting: Iridium has nearly completed the deployment and installation of its new broadband satellite network, Iridium NEXT/Certus. This should dramatically decrease the cost of satellite broadband services, increase its availability and access to the consumer, and spur innovation in developing the next generation of satellite communications devices.
The following table compares the key overall features of the most popular messaging devices available now from SPOT and Garmin, and soon from Somewear.
|Device||Weight||MSRP||GPS Navigation||Messaging||Keyboard Type||Smartphone Integration||Weather Forecasting||Visual Map Display|
|SPOT Gen3||4 oz||$150||no||1-way, canned only||none||none||no||no|
|SPOT X||7 oz||$250||yes||2-way||Integrated (physical)||none||no||no|
|Garmin Inreach SE+||7.5 oz||$400||yes||2-way||Integrated (virtual)||Yes, optional||yes||yes|
|Garmin inReach Explorer+ (*)||7.5 oz||$450||yes||2-way||Integrated (virtual)||Yes, optional||yes||yes|
|Somewear Global Hotspot||3.0 oz||$320||No, requires mobile app||2-way||none||Yes, required||yes||no|
|Garmin inReach Mini||3.5 oz||$350||yes||2-way||Integrated (virtual)||Yes, optional||yes||no|
(*) The Garmin inReach Explorer+ includes features tyipcally found in high-end mapping GPS units, including a pre-loaded base topo map set, a pressure altimeter, and compass.
From this table, you can readily identify the unique benefit of the Garmin inReach Mini: It’s the lightest 2-way messenger that doesn’t require (but notably, allows for the use of) a smartphone to enhance usability and features (e.g., a visual map display).
Setting up the Garmin inReach Mini
To show how the Garmin inReach Mini works and highlight some of its core features, I’ll walk through the exact process I used for setting it up, preparing it for first-time use, using its various functions on a hike, and evaluating post-trip data.
In the box:
- inReach Mini device (97 g / 3.4 oz verified on my digital scale)
- Micro USB cable (3 ft)
- Carabiner harness adapter (4 g)
- Spine mount adapter (13 g, includes screw)
- Carabiner (13 g)
- Allen wrench for adapter screws
My very first impressions upon holding the Garmin inReach Mini:
- It seems very well-built and durable and has the feel of an expensive device that exudes high manufacturing quality.
- It’s really small – much smaller than I thought it would feel (see photo below; for context, I wear size Small gloves).
The Garmin inReach Mini has six buttons (A-E) and one interface (F):
- Power on/off (recessed to prevent accidental push)
- Up/Down (2 buttons; used to toggle between menu items)
- OK (used to select a menu item)
- Return (used to go back to a previous menu)
- SOS (protected by a snap cover to prevent accidental push)
- Micro-USB interface (protected by a snap cover to prevent dust/moisture ingress)
The Garmin inReach Mini ships with two adapters for attaching the device:
- A carabiner harness adapter, which consists of a screw, a 3/4″ loop of 5/8″ nylon webbing, and a carabiner. The total weight of these three items is 17 g. Instead of using this adapter, you could also tether the unit to your pack using a thin piece of cord affixed to a strap anchor on the device.
- A spine mount adapter, which can be used to attach the Garmin inReach Mini to a variety of device mounts sold by Garmin (e.g., suction cup mounts for car windshields, Molle strap mounts for backpacks, and bicycle handlebar mounts).
I expect to stow my Mini in a backpack pocket (either my top lid or hip belt pockets), and don’t see the utility of using either type of mount. However, I could see the benefit of attaching a cord tether for packrafting or backpacking so I don’t accidentally leave the device somewhere. For backpacking, I made a 10-inch long tether loop using 1mm Dyneema core cordage for girth hitching the unit to a loop on my pack, belt loop, packraft grab loop, etc. It weighs 1 g.
Charging the Device
When I unpacked the Garmin inReach Mini from its box, it was about half-charged. A 3-foot micro-USB charging cable is included. The USB port is on the left side of the unit, protected beneath a rubberized cap.
After draining the unit’s battery, I was able to fully charge it (using wall power) in 118 minutes.
When you first power up the device, you are taken to the Device Setup menu, which gives you the option to either Activate or Skip.
Upon selecting Activate, you are instructed to visit inreach.garmin.com to activate the device.
However, before activating your Garmin inReach Mini, you need to decide what you want to do with the device, so you can wisely select the plan that has the best value for your needs.
Shopping for an inReach Service Plan
Garmin inReach devices require a service subscription through the Garmin inReach Global Satellite Technology service plan to use live tracking, messaging, syncing, and SOS features.
- Plan details are described here.
- To signup for a plan, you must have your inReach device in hand; then you can signup here.
Decision #1: Personal or Professional Plan?
Professional plans include tools that allow for the centralized administration of several devices. Based on Garmin’s subscription marketing copy on their website, it’s implied that advanced API access for developing custom inReach applications is only available with professional plans. I’ve heard conflicting reports about this, and couldn’t confirm directly with Garmin before this review’s publication time. If API access is important to you, then you may have to consider a professional plan.
Otherwise, the overwhelming majority of recreational end users should select a personal plan.
Decision #2: What Plan Level?
Four plan levels are available:
- Safety – The minimum plan suitable for users who only want to use the inReach for “just-in-case” emergencies. It includes an unlimited number of SOS messages and preset SMS sending, and ten custom text messages per month. Surcharges are otherwise levied for location pings, tracking points, and message overages. One basic weather request per month is included, but premium (more detailed) weather requests come with a surcharge.
- Recreation – The plan that will appeal to most recreation users, because it offers unlimited tracking and location pings, and 40 custom text messages per month.
- Expedition – The power user plan, offering unlimited text messages, tracking points, location pings, and basic weather requests. The only surcharges are for premium weather requests.
Extreme – Same as Expedition, but tracking intervals are decreased from the standard interval of 10 minutes to 2 minutes. The Extreme Plan may be of interest to pilots and cartographers.
Decision #3: Freedom Contract or Annual Contract Plan?
Garmin offers both annual contracts and month-to-month service plans (called “Freedom” plans). Here’s how they compare:
|Plan Type||Activation Fee||Minimum Term||Upgrade Fee||Downgrade Fee||Billing Frequency|
|Annual||$19.95, one time||1 year||none||$24.95||monthly|
|Freedom||$24.95, annually||30 days||none||none||monthly|
In addition to the prices above, users are also subject to the federal Universal Service Fund fee and any applicable state and local taxes.
In addition, non-U.S. customers are subject to applicable VAT.
The following table outlines the inReach service plan pricing structure as of June 2018:
For my own needs, I knew that I didn’t need a professional plan, as I don’t manage a device fleet.
In addition, I wanted the ability to post relatively frequent updates to both social media channels as well as to communicate with my family and company staff. And although I still appreciate the ability to use a satellite phone for medical emergencies, the ability to save more than half a pound, and rely on the inReach Mini alone, is awfully tempting. Regardless, It wouldn’t be hard for me to exchange several dozen text messages during a multi-day trip. Weather updates would be interesting to have as an option, but not a critical requirement for me in most situations. The one exception to this would be if I wanted to camp in an exposed location above the treeline. In that case, I’d certainly like to know if thunderstorm activity was in the forecast!
So the question I had to answer was this: how many text messages would I have to send to make the Expedition plan more economical than the Recreation plan?
For an annual contract, the difference between the Expedition and Recreation plans is $25/month. Since that Recreation Plan offers 40 text messages without overages and charges $0.50 for each message thereafter, the additional cost of the Expedition plan is only worth it if I’m sending a monthly volume of 90 or more messages.
Here’s how it all works out:
- If you’re sending and receiving less than 40 messages per month, the Safety Plan offers the best value.
- If you’re sending and receiving between 40 and 90 messages per month, the Safety and Recreational plans offer similar value.
- If you are sending more than 90 messages per month, the Expedition Plan offers the best value.
Interestingly, if all you are concerned about is messaging, there are no advantages to purchasing the Recreational Plan. The only real benefits it offers offer the Safety Plan are unlimited location pings and tracking.
In other words, the Safety Plan offers the best value if you need only messaging capabilities, and the Recreational Plan provides the best value if you also need tracking capabilities.
The next graph reinforces this conclusion:
- If you need less than 120 location pings (including tracking points) per month, the Safety Plan offers the best value.
- If you need more than 120 location pings (including tracking points) per month, the Recreational or Expedition Plans offer the best value and are further dependent on your messaging needs (see previous graph).
To put this into perspective, if you ping a location (or send a track point) once a day (for example, each night you arrive in camp), then the Safety Plan offers you up to 120 days of usage before it becomes more costly than the other two plans.
On the other hand, if you ping a location every 10 minutes, and hike about six hours a day, then the Safety Plan becomes very costly after only two days of use (after which you will have used 120 location pings).
A similar analysis can be made for a “Freedom” contract. With a difference in cost of $30/month, the only scenario that makes the Expedition plan worth the extra cost is if I’m sending a monthly volume of 100 or more messages.
I knew that I had the option of upgrading without penalty. I wanted to be able to record my route using fairly frequent tracking intervals (as frequently as once/hour, i.e., 50 to 80 points for a weeklong trek). This makes the Safety Plan a reasonable option. However, while tracking was a nice feature, I was more interested in two-way messaging capabilities (otherwise, I might consider a Spot Gen3) to stay in communications with my family and staff. Therefore, for me, the Recreational Plan was the most viable option.
When evaluating whether or not to select a Freedom or an Annual Contract, I wanted to know how many months of use per year were required to make the Annual Contract a better value. Noting that the Freedom contract requires an “annual service fee” and the Annual contract requires only a one-time initiation fee, here are the results of my analysis:
These graphs show that if you want inReach service for more than about 8-9 months of the year, then an Annual Contract may be a better value for you. However, my guess is that most users, who hike during the fair-weather summer window of June through September, will benefit from the privilege of suspending their service and opting for Freedom contracts.
As for me, I opted for the Freedom contract. As a matter of personal financial principles, I wanted to have the flexibility for month-to-month activation/deactivation as needed. As a Recreational plan subscriber, I have to acknowledge that the price of this “freedom” could be as much as $100 per year if I maintained my service for all twelve months of the year.
Signing up for Service
To sign up for service, as instructed by the device, visit inreach.garmin.com:
The process for signing up is very straightforward, and just enough instructions are provided to guide you through the process without undue duress. The process involves seven steps:
- Entering your device information (IMEI number and Authorization Code, which are provided on the device screen once you select Activate and press the OK button), email address, and account password.
- Entering your personal information (name, address, phone numbers, and any emergency medical info that would be provided to search and rescue personnel).
- Entering your emergency contact information (primary and secondary contact names, phone numbers, and email addresses).
- Selecting your contract type (Annual or Freedom) and plan type (Safety, Recreational, Expedition, or Extreme).
- Selecting your SOS Features:
- GEOS Emergency Response Coordination (included with all plans).
- Additional GEOS Search and Rescue Benefit Program (provides up to $100,000 in search and rescue resources for an additional $17.95/year).
- GEOS Worldwide Medical Evacuation (provides up to $1M for a lifesaving evac for an additional $129.95/year for US and Canada or $175/year for International coverage).
- Entering your billing information.
- Reviewing and confirming all of your information.
The entire process took me less than 10 minutes to complete. Upon confirming, an activation status window pops up:
It disappeared after about a minute, and I was returned to a screen that listed the final steps required to complete activation:
- Activation: Take the inReach outside with a clear view of the sky and press the OK button to begin the (final?) activation process. The device then acquires a GPS fix, sends an activation request, and then waits for the activation confirmation. This process took about 5 minutes to complete.
- Bluetooth Pairing: Upon pressing the OK button, the device walks you through the process of pairing with your smartphone via Bluetooth. The pairing process took about 15 seconds with my iPhone SE.
- Test Message: Upon completing Bluetooth pairing and pressing the OK button, the device notifies that you have a new message from email@example.com. I replied to the message to confirm that everything was working OK (up to five test messages per month can be sent for free). A confirmation reply (to my reply) came in a few minutes.
The inReach Website
At this point, with the device working, I went to my account at inreach.garmin.com, and discovered the location of my inReach on the map:
The inReach website offers eight functions, each accessible via a tabbed menu:
Home – provides access to subscription and billing information, and some overview statistics of usage (tracking points, messages, etc.).
Map – displays an overview map (topo, road, or aerial imagery) with device location, tracks, routes, waypoints, etc.
Inbox – provides a cloud-based location for all inReach messages.
Contacts – provides the ability to enter contact info for the people you contact the most. This can be synced.
Messages – provides the ability to edit both Preset and Quick messages that are available from your device. Here’s the difference between the two:
Social – allows you to toggle on/off public visibility of the MapShare service, where people can track your progress, or link your Facebook and Twitter accounts.
Account – provides all of the same setup info (and the ability to edit it) that you entered/selected upon signing up for a service plan.
Sync – provides instructions for syncing your inReach info (contacts, waypoints, routes, etc.) from the website to your device, and between the Earthmate mobile app and your device.
Syncing the inReach Mini
The Garmin inReach Sync application (available for Windows/Mac) is required to sync the inReach Mini to the inReach website via your computer to install available updates, as well as syncing contacts, quick text and preset messages, and other data.
The inReach can also be synced via the Earthmate mobile app.
Setting Up the Garmin Earthmate Mobile App
The Garmin Earthmate app (available in both Apple and Android versions) can be used to pair the Garmin inReach Mini to your smartphone. I use an iPhone SE. The app runs smoothly, and I’ve never observed any crashes, hangups, bugs, or slow processing times using the app.
The app gets mixed reviews from users, but most reviews are very positive. As always, read app user reviews with a grain of salt. Many critical reviews are not detailed enough to provide context outside of a user’s reactive frustration.
I found the app very easy to use, with an intuitive user interface, and have no complaints about it worth mentioning here.
Before using the Earthmate app on a hike, I downloaded the Garmin Base Data and Garmin Topo North America map sets (about 250 MB of data), along with the USGS Quad Sheets and Color Aerial Imagery maps for the areas of the Medicine Bow National Forest near my home where I spent most of my hiking time. The latter two map sets for my home hiking area added another 1 GB of data.
Accordingly, I’d repeat this step (downloading local maps) before trips taken to other areas as well.
For most trail hiking, the Garmin Topo North America map set is sufficient. I like USGS Quads if I’m doing any cross-country navigation, and I like Color Aerial Imagery for identifying river hazards for packrafting trips, and potential campsite locations.
Using the Garmin inReach Mini in the Backcountry
The number of things the Garmin inReach Mini can do is pretty incredible, given its diminutive size and weight. However, at this point in the review, I think it’s important to distill what I believe are the essential core functions of the device: GPS, messaging, and weather forecast retrieval.
The Garmin inReach Mini as a GPS Device
The Garmin inReach Mini offers what I would call basic GPS functionality.
“Basic,” in the sense, that its screen doesn’t offer a high enough resolution (128 px square) for integrated mapping functionality that distinguishes basic from advanced GPS units.
As with any basic GPS unit, the Garmin inReach Mini can perform the following functions:
Location Fix, Sharing, and Waypoint Marking
After navigating to the device’s Location menu and waiting for a GPS fix, your current location’s latitude, longitude, and elevation are displayed on the screen:
Then, upon pressing the device’s OK button, you have the option to either share the location via messaging or mark the location as a waypoint.
As with any GPS, the Garmin inReach Mini provides the ability to navigate towards any waypoint, or along a route. Once a waypoint is selected, and the Navigate feature is activated, you can monitor progress towards the waypoint on either the unit’s home screen or its navigation screen:
In addition, the inReach Mini provides a “compass” page that provides data about your speed and “direction”:
But it’s a bit misleading – the direction indicates the direction of travel and has nothing to do with device orientation, as one might expect with a magnetic compass.
Finally, in addition to navigating towards waypoints and monitoring your travel speed and direction, you can record a route by tracking.
Once the tracking feature is selected, you have the option to specify both the send interval (the time interval for which tracking messages are sent to MapShare; 10 min (default), 20 min, 30 min, 1 hr, 2 hr, or 4 hr) and the log interval (the time interval for logging locations along your route for better route resolution (1 sec, 1 min, 2 min (default), 5 min, or OFF).
It’s worth noting that using a log interval of 1 sec drains the battery quite significantly; however, this might be a useful interval if creating high-resolution route tracks and more precise distances are important to you.
The Garmin inReach Mini as a Messaging Device
The GPS and tracking features discussed up to this point would make the Garmin inReach Mini a compelling choice as a standalone GPS unit. It offers GPS and tracking features similar to those found in other small and light basic GPS units such as the Garmin Foretrex 601 (3.1 oz).
However, GPS functionality alone is not what makes the Garmin inReach Mini so appealing – it’s the inReach Mini’s messaging features that make it such a powerful device. The only other devices that integrate a functional GPS as described above, with two-way messaging, are heavier (e.g., the inReach Explorer+ and inReach SE+ at 7.5 oz and the Spot X at 7.0 oz). The primary advantage of the inReach Explorer+/SE+ is an integrated color screen that can display high-resolution maps. The primary advantage of the Spot X is the integrated physical keyboard that makes typing messages easier.
That the Garmin inReach Mini, as a two-way messaging device, also includes highly functional GPS navigation features, makes it a far more valuable device than what may be the most popular device in this category, the Spot Gen3 (which weighs 4.0 oz, can only message 1-way, has no custom messaging abilities, and no integrated GPS navigation features).
Therefore, let’s explore the Garmin inReach Mini messaging functions, which include location messaging, text messaging, weather forecasting, inReach-to-inReach device messaging, and social media sharing.
Location Messaging: Sending Locations with the Garmin inReach Mini
Location data can be sent in one of two ways:
A Location Without a Message
A location (either your current location or a preset location or “waypoint”) can be sent to any contact’s email or mobile phone number.
Included in the location data are the latitude, longitude, elevation, whether the hiker is moving or stationary, a link to the location on a map at inreach.garmin.com, and the device owner’s name.
A Message With a Location Attached
Optionally, a location can be “attached” to any outgoing text message. In this case, the location data isn’t included in the message, but a link to the location on a map at inreach.garmin.com is.
Whether a location is sent with or without a message, clicking the link reveals the location on the map and the data associated with that location:
Conveniently, the recipient can use the map interface at inreach.garmin.com to view the location, the sender’s message (if any), and reply to the message directly (see reply box in upper right-hand corner). As with most online maps, the recipient can zoom in and out, and change map layers between road maps, topo maps, and aerial imagery.
Using the Garmin inReach Mini as a Text Messaging Device
One of the Garmin inReach Mini’s most important features to me is the ability to exchange text messages with friends, family, or company staff.
The process by which text messages are sent and received on the device itself is straightforward and uncomplicated.
However, for frequent (non-emergency) messaging, my frustration level with using the device’s virtual keyboard achieved sky-high status. Can you imagine toggling through an alphabet using only up/down and select keys to craft the high literature that is a text message? Granted, there are some rudimentary autocomplete options available, along with a rather non-intuitive order of key presses for backspacing, front spacing, symbols, capitalization, and punctuation, but after spending half an hour mastering the not-a-keyboard interface, my fingers were seriously aching.
- If you are going to use the Garmin inReach Mini for emergency text messaging (other than canned preset and quick text messages), and you won’t be pairing it with the Earthmate mobile app on another device, learn how to use the virtual keyboard.
- If you are going to use the Garmin inReach Mini for frequent text messaging and are not a fan of acquiring carpal tunnel syndrome as a result of rapidly pressing the same three buttons a thousand times to compose a single message, plan on pairing your inReach Mini with a mobile device with a real virtual keyboard (e.g., iOS or Android smartphone) running the Earthmate app.
- If you don’t hike with a smartphone, but want the two-way messaging features of inReach devices, consider instead the bulkier and heavier inReach SE+ or Explorer+, both of which offer full virtual keyboards where characters can be selected with the four-direction device toggle. For a Blackberry-style physical keyboard (which provides the best typing experience of any satellite messaging device), take a look at the Spot X device.
Weather Forecasting with the Garmin inReach Mini
One of my favorite features of the inReach service is the ability to download point location weather (current conditions and forecast) to the device.
Garmin’s weather forecasts are delivered by the Dark Sky weather network, known for its terrific API and weather modeling techniques that are among the best available (not considering one recent and very funny hiccup).
I’m a bit of a weather forecasting junkie. I’ve been using Dark Sky weather forecasts nearly since they launched, and have found it (anecdotally, at least) to be more reliable at rain, thunderstorm, and wind forecasting than any other network I’ve tried (and I’ve used dozens).
A weather forecast can be downloaded to the Garmin inReach Mini for either your current location or a specified waypoint, to help you answer questions like “What will the weather be like at our Friday night campsite?”
All weather forecasts include the following data types for both current and future forecast times:
- % chance, total volume (e.g., in inches) and type of precipitation (e.g, light rain, heavy rain, sleet, hail, snow);
- Humidity %;
- Wind speed and direction;
- Barometric pressure.
Two types of weather forecasts are available. They offer the same data types, differing only in the frequency and duration of the forecasts:
- Basic – for the cost of a single text message, the Basic forecast provides forecast data for a total of 2.5 days (60 hours) after the request:
- Every two hours for the first 12 hours;
- Every six hours for the next 48 hours.
- Premium – for $1.00 per request, the Premium forecast provides forecast data for a total of 5 days (120 hours) after the request:
- Every one hour for the first 12 hours;
- Every two hours for the next 12 hours;
- Every three hours for the next 12 hours;
- Every six hours for the next 36 hours;
- Every twelve hours for the next 48 hours.
The Basic forecast takes a minute or two to download once the request has been sent by the inReach Mini. The Premium forecast seems to take about three to four times as long to retrieve on average.
I can see the benefit of the long-range (more than 2.5 days) forecast provided by the Premium weather service in the following case:
- I’m still going to be in the backcountry for the next several days;
- I’m in need of a longer-range forecast if it means that a severely inclement weather forecast will result in a possible route change.
I can also see the benefit of a forecast with a higher level of frequency (e.g., a short-term forecast that is hourly instead of every two hours), but usually only in the case where I’m trying to time the crossing of a high pass during thunderstorms, or on a mountaineering trip where down-to-the-hour route decision making may be required.
Otherwise, I think most backpacking scenarios would benefit significantly from having a basic weather forecast, and only incrementally, if at all, from having a premium weather forecast.
Messaging to other inReach Devices
All Garmin inReach Devices (including the Mini) can communicate with each other through satellite messaging. This feature would be of great value for parties who split up during a trip and wish to communicate their locations, status, or meetup times and locations to each other.
Having hiked in parties that have split up (either voluntarily or involuntarily), this capability might be a significant stress-reducer! On many occasions, our split party has failed to meet up at a specified time and place. In addition, as a guide, I’ve had to split parties in order to send small subgroups out to the trailhead for assisted self-evacuations of clients, and it would have been nice to have been able to communicate with the evac crew during the evac and subsequent rejoining of our main party later in the trip.
Of course, this capability requires that each separate subgroup of a split party is carrying their own inReach device.
The process of messaging from one inReach device to another is simple: every inReach user account is assigned a unique inReach email address for inReach-to-inReach communication. If you have an inReach device you can send a message from your inReach to another inReach by using the inReach address for the recipient.
Posting to Social Media: MapShare, Facebook, and Twitter
The Garmin inReach Mini can be connected to MapShare, Facebook (both personal profiles and pages you manage) and Twitter accounts. This connection is created during account setup at inreach.garmin.com. Once connected, the device must be synced to inreach.garmin.com using either the Garmin Sync application on your computer or the Earthmate app on your mobile device. Once the sync is complete, “Post to Facebook” and “Post to Twitter” will subsequently appear in your messaging contacts. The process works seamlessly and is simple and elegant to use.
For this review, I’ve shared part of the track of a hike that Stephanie and I took in Wyoming’s Snowy Range on my MapShare page at https://share.garmin.com/bigskyry.
How does pairing the Garmin inReach Mini with the Earthmate mobile app enhance its GPS and Messaging functionality?
Using the Garmin inReach Mini as a standalone device is surprisingly easy but requires that you spend a day or two playing around with it to become accustomed to the hardware interface and software menu systems.
The only exception, as you might have guessed, is using the so-called virtual keyboard to compose text messages. That’s a nightmare.
With that in mind, if I was trying to save every ounce I could, but still needed a two-way satellite messaging device for emergencies, infrequent communications, and periodic check-ins with my family, I would prefer to carry the Garmin inReach Mini vs. the easier-to-use (but heavier) inReach SE+, inReach Explorer+, or Spot X devices.
So that leads me to an important question:
Is the Earthmate mobile app (and mobile device) worth the additional weight?
For me, the answer is a resounding yes. Here’s why:
- The Earthmate mobile app allows me to compose text messages using a “real” smartphone keyboard. If you are ever forced to use the Garmin inReach Mini’s virtual keyboard to type a custom message, you’ll immediately find yourself in keyboard purgatory, and Earthmate is now looking like a pretty bright angel.
- Earthmate allows you to manage all device functions from the app, including all setup and customization functions, message management, and waypoint and route management. It’s a well-designed mobile app that takes advantage of modern mobile UI design. Accordingly, it allows you to accomplish everything faster and more intuitively (especially messaging management).
- Earthmate offers integrated mapping on the full-color, high-resolution screen of your smartphone. Therefore, it essentially provides me with all the features of the highest-end GPS units on the market. I can download detailed map overlays, and see my route and location on a map in real time.
- Earthmate offers a magnetic compass feature.
- Earthmate’s weather data interface allows me to scan and read weather data downloaded to the inReach Mini much faster and more effectively than on the inReach Mini device.
- Earthmate allows me to use my smartphone’s UI instead of the device’s buttons. The entire experience is faster and more intuitive for me.
- I usually take my smartphone with me on backpacking trips anyways for journaling, e-book reading, photography. So why not use it as my UI for the inReach Mini?
The Garmin inReach Mini is durable, waterproof, well-manufactured, has rubberized buttons and holding surfaces, and a highly scratch-resistant screen.
It’s easy to read in bright sunlight.
And it’s almost comically tiny in size and lighter weight than any other satellite device I’ve used.
Battery life seems to be on par with the manufacturer’s claimed specifications.
Garmin doesn’t publish the battery capacity in its literature, but taking the unit apart is easy enough (although it will compromise its waterproofness and you’ll need to reassemble using a new gasket, new screw seals, etc. – don’t do this to your device).
The battery is a 1,250 mAh rechargeable lithium-ion battery.
Pairing the Garmin inReach Mini to a mobile device via Bluetooth, and maintaining live tracking and/or route logging does drain the battery a little bit faster, but much less than I thought. When I ran side-by-side comparisons of a three hours (no Bluetooth vs. Bluetooth pairing), the paired device drained the battery just two percentage points more than the unpaired device.
I was curious to understand how tracking and logging affected battery drain rates, and conducted a number of tests at various tracking and logging intervals, and then came up with the following approximations (which you can consider to accurate to within about 15%):
- One track point seems to consume about 4 mAh of battery capacity. To put this in context, if logging is turned off and tracking is turned on at 10-minute intervals, a full battery can be used to track approximately 52 hours of travel.
- One log point seems to consume about 0.005 mAh of battery capacity. To put this in context, if tracking is turned off and logging is turned on at 1-second intervals, a full battery can be used to log approximately 70 hours of travel. At 1-minute intervals, a full battery can be used to log approximately 400 hours of travel.
These numbers can be used to estimate battery drain rates given various combinations of tracking and logging rates.
Also to consider is that battery life will drain faster in response to the following:
- Sending and receiving messages, including weather forecasts.
- Pairing the device to a smartphone via Bluetooth.
- Using the device (e.g., with the screen and backlight on).
The Garmin inReach Mini’s software interface is familiar.
I’ve used Garmin GPS units, including inReach, Oregon, Montana, eTrex, and Foretrex models for many years. Garmin device evolution towards the classic four-button interface (up/down toggle, OK/select, and return (previous menu) that is now standard among GPS, digital audio, and digital camera manufacturers makes using the device intuitive and simple enough (with a little practice, if you’re new to this type of interface).
And, in spite of my somewhat snarky comments about the virtual keyboard, it’s about as good as you can get with a four-button interface, and honestly, with a little bit of practice, I have no complaints. I mean, c’mon – this is a tiny, 3.4-ounce device that packs an extraordinary amount of power.
My only wish is that it was capable of voice-activated command and speech-to-text transcription! How cool would that be?!
The inReach website (inreach.garmin.com) serves two functions for the Garmin inReach Mini user:
- Device and service setup, management, and route planning.
- Messaging and location monitoring for private users (contacts).
I have no issues or complaints about the website, and it’s easy and intuitive to navigate once you find your way around.
Earthmate Mobile App
The Earthmate mobile app provides a very rewarding experience for me. I didn’t have to read any instruction manuals to figure out how to do everything that the app has to offer.
Granted, I’m a daily smartphone user, and that probably helps.
Earthmate is regularly updated and reflects contemporary mobile UI design, which makes it a effective interface for operating the Garmin inReach Mini.
MapShare could use a little work.
I’m guessing that if I wanted to share my locations, tracks, and messages with my mom via MapShare, I’d have to spend a little time with her explaining how it all worked.
MapShare feels more like a technical software interface than a place where “family and friends” can follow along.
A simpler user interface that incorporates tasks and actions in a more obvious manner would be helpful to digital UI neophytes.
The Garmin inReach Mini by itself provides quite a positive experience. If I were not a smartphone user, I wouldn’t hesitate to use the Mini vs. the other heavier, bulkier, and more expensive inReach devices. The ability to have basic GPS functionality, and the ability to exchange text messages with my wife while on a trek makes this device incredibly valuable to me – and her.
Add the Earthmate app on a mobile device with a color, hi-res display, and you now have an extremely powerful mapping GPS combined with a much faster and intuitive UI. Now it’s a rather robust and capable GPS and messaging system that far exceeds any other standalone mapping GPS or messaging device on the market – for less weight.
With MapShare, Facebook, and Twitter integration, you can feed your inner narcissist by ensuring that others can see that you are spending time hiking and camping in epic locations while they suffer #fomo in their cubicles.
Through the years, I’ve used satellite phones, Spot messengers, other inReach models, and even Inmarsat broadband satellite modems. However, none of these systems have offered the capabilities of GPS navigation, mapping, and two-way messaging for as little weight as my iPhone SE paired to a Garmin inReach Mini.
Strengths & Limitations
- Lightest standalone two-way messaging device on the market.
- Durable and well-manufactured.
- Easy to use and intuitive user interface with classic four-button interface.
- Outstanding UI experience when paired to a mobile device and Earthmate app.
- Social media integration via MapShare, Facebook, and Twitter.
- Very reliable and reasonably fast satellite communications using the Iridium network.
- Cheaper communications than a satellite phone.
- Limited screen size and resolution eliminates mapping as a feature when used as a standalone device.
- Virtual keyboard is slow and difficult to use if the device isn’t paired with a mobile app on a smartphone.
- Sorting out service plans and contracts is confusing. Too many options!
Iridium 9575 Extreme Satellite Phone
A satellite phone gives you voice calling capability that a messaging device can’t provide. However, before I started using messaging devices, I was using satellite phones to exchange text messages with friends, family, coworkers, medical consults, and rescue personnel. The Iridium 9575 Extreme is the model I currently use, and the model we send out with our guides for the Wilderness Adventures program.
The Iridium 9575 Extreme uses predictive text messaging in combination with the phone’s 12-button keypad (remember texting on your old bar- or flip-phone?). Composing text messages is much faster using this method than with the limited 4-button interface and virtual keyboard of the Garmin inReach Mini.
However, the Garmin inReach Mini is 10 oz lighter, much smaller, and several hundred dollars cheaper than an Iridium satellite phone. In addition, the service required to send and receive text messages is significantly less expensive than the service needed to maintain an active SIM on a satellite phone, on the order of hundreds of dollars per year for an equivalent number of messages sent and received.
Another primary advantage of messaging with a device like the Garmin inReach Mini vs. voice calling (and text messaging) on a satellite phone is that reception tends to be more reliable with a messaging device. When I attempt to send messages via my Iridium 9575 Extreme, I often have to retry sending them several times due to reception issues. I’ve yet to have a single message sending failure with the Garmin inReach Mini.
Stick with the satellite phone if you need voice-calling abilities. Otherwise, the Garmin inReach Mini (especially when combined with a mobile device and the Earthmate app) is a far more powerful and capable device for GPS navigation, mapping, and messaging.
The Spot Gen3 is only capable of one-way messaging using a very limited number of predetermined messages (check-in/OK, help, and SOS).
Otherwise, the Spot Gen3 cheaper and simpler to use.
The Spot Gen3 is also half an ounce heavier than the Garmin inReach Mini.
The Spot Gen3 still occupies a niche where a user wants a cheaper device with cheaper service that offers limited check-in (“I’m OK”) and SOS functionality. However, the Garmin inReach Mini sets a new standard for the amount of performance and capability that can be packed into a package this small and light.
Spot X, inReach SE+, inReach Explorer+
The Spot X features a Blackberry-style physical keyboard, making it the best option for composing messages if you don’t plan to pair your messaging device to a Smartphone. Otherwise, the Spot X is much bulkier and twice the weight as the Garmin inReach Mini.
Garmin’s other inReach models, the SE+ and Explorer+, features everything the inReach Mini offers in a package that includes a color display that is larger and has a higher resolution. This offers two key benefits: the ability to integrate mapping functions on the device, and a better virtual keyboard.
However, pairing any inReach device with a smartphone and the Earthmate mobile app makes GPS navigation and mapping an entirely different experience (in a good way). Thus, my need for the mapping and display capabilities of the larger devices is replaced by my smartphone anyways. For me, replacing my old inReach device (the SE+) with the Garmin inReach Mini is an easy decision.
Somewear Global Satellite Hotspot
Although not yet on the market, the Somewear Hotspot will find favor among users who simply want to use their smartphone as their primary GPS navigation, mapping, and messaging interface.
Unfortunately, the Somewear Hotspot won’t offer any of these capabilities when not paired with a mobile device, rendering its functionality “extremely limited” in the case of a mobile device failure, or if you just want to leave your smartphone at home. As a standalone device, the Somewear Hotspot will still be able to drop pins so people back home can track your progress, and the unit has an SOS button. This makes it more comparable to a device like the Spot Gen3.
However, I prefer the full capabilities of the Garmin inReach Mini when considering its functionality as a standalone device: GPS navigation, two-way messaging, and weather forecasting are available, all without pairing it to a smartphone.
Service Plans and Pricing Structure
Garmin inReach service plans are somewhat confusing and offer too many choices. I like the idea of a la carte services (pay for what you actually use) for occasional/intermittent use and unlimited usage plans for power users. I abhor contract plans, change-of-service up- and down-charges, and service initiation charges. Complex pricing structures are the products of the industry of “finance marketing” that has infected most telecommunications industries today.
Garmin would do well to create goodwill for their consumers by simplifying their pricing structures, making them easier to understand and make decisions without having to consider formulas and breakeven analysis requiring charts and graphs.
Spot X service plans reflect a more consumer-friendly approach to device usage pricing. When comparing Spot X service to inReach service, Spot X service is significantly cheaper.
It’s worth noting here that the Spot X uses the Globalstar satellite network, while the Garmin inReach Mini uses the Iridium satellite network. User reviews of both networks reveal important trends that suggest a much higher level of reliability (especially with messaging) using the Iridium network.
Should I wait for the next new device to come out?
In the next 12 months, you’re going to see more players in the satellite hotspot market (with similar capabilities as the Somewear device).
But these devices won’t provide any new capabilities that can be had with currently available devices, which offer:
- Voice-calling and messaging (satellite phones);
- One-way messaging (tracker-style devices like the Spot Gen3);
- Two-way messaging and GPS units (inReach devices)
The primary limitation with today’s devices is the limited data bandwidth of the satellite networks they use.
Iridium is almost done building their new broadband network, with all of the satellites deployed and operation by the end of 2018.
Having used a broadband modem (Inmarsat iSatHub terminal) in the backcountry on a number of trips, the two features I find particularly interesting are:
- Voice-over-IP calling;
- Photo sharing.
So, the next wave of devices, available in 2019 and beyond, will sport these features and significantly change how we use devices for communications and trip sharing in the backcountry.
However, initial device costs and service pricing plans are expected to be quite expensive until market competition sorts it all out. If history is any indicator of the future, we are still three or four years away from seeing cost-effective consumer devices capable of broadband messaging, voice-over-IP calling, and photo sharing.
Until then, we can dream of the new inReach Mini+, a broadband-capable model that allows us to place and receive VOIP calls on our smartphone, post real-time photos from our trips to Instagram, and more.
For now, the Garmin inReach Mini is the market leader in this category, and will likely remain so for quite some time: it’s the smallest, lightest, and most powerful two-way messaging device on the market.
- Distribution of the Garmin inReach Mini is very limited right now. If you want this device in time for your next trip, we recommend purchasing the Garmin inReach Mini from REI online directly.
