Digital thermometer

I have a Highgear Altimeter Watch that has a digital thermometer. My experience is like yours, while you are wearing it, your body heat throws it way off, however, with the watch off, it seems accurate. That being said Highgear also makes a multi function timepiece that isn't a watch, but is on a carbiner. That might be what you are looking for.

Don,
I have a Brunton ADC Wind.

I displays current temperature as well as logs the last 24 hours. I find it slow to respond to big changes, but it does track well to typical falling nightime temps, which is what I am usually interested in.

It comes with a detachable lanyard. The buckle end is attached with a plastic rivet which will break the 3rd time you use it. I removed everything and added a loop of very small cord, which allows me to hang it on my pack or in a shelter. Although it is big in size, mine weights 1.85 ounces.

Nothing that you wear on your wrist will give accurate ambient air temperature readings because of the influence of your own body heat. Some of the best instruments designed for measuring environmental conditions (e.g. temp, wind speed, etc) are made by Kestrel. If your main objective is to accurately get temperature measurements, I'd go with the Kestrel 2000. It measures wind speed, temp, and calculates wind chill temp also. it's about 1.5 oz and less than $100 ($86 on Amazon). Kestrel also makes more sophisticated devices that measure many more environmental conditions including barometric pressure (and altitude), relative humidity, dew point, and more, along with memory storage for uploading to a computer. But I think for basic temp, you can't beat the Kestrel 2000.

Update: I have both a Kestrel and a Brunton ADC and the temp measurement on the Kestrel is almost instantaneous compared to the Brunton which is incredibly slow in getting a reading.

I have one on my Avocet watch and have the same experience others have mentioned.

However, I try not to use that feature, especially in the morning while contemplating leaving my warm little nest to face the coming day. Sometimes, you're better off not knowing; ignorance can be bliss.

I bought a digital thermometer a month ago at REI for 8-9 dollars. It is called the Digital Dangler and comes with a neck strap. It has the date, time and temperature. It seems to be pretty accurate for such a cheap little gadget.

Don,

I've been wanting a digital thermometer myself. If for nothing else, just to know if my sleeping bag, etc, are performing to spec. I might look at the Coughlins one to start. If it's at REI, there's no risk if it doesn't work well in testing.

The Brunton looks good too.

I feel like if I'm going to spend over $50, I might want to think about spending the extra money to get something that has an altimeter/barometer.

As far as weight, I weight a 1.25oz digital watch right now, so I'd be adding less than an oz.

I've been using the Thermocrons for several years now. Extremely light, accurate enough, but no readout in the field.
