I had an interesting experience last week on a trip flying to a location and then getting a rental car. On my first day of backpacking I had left most of my gear at a campsite and from there gathered a few items to walk a few miles to an overlook. On my walk to the overlook I had a waist pack that contained my phone, camera and rental car key. In my very lighweight/small backpack had some food and water. On my way back about a mile from my campsite I had to use the bathroom so went into the woods and then back to my campsite.
An hour or so later from my campsite I realized I did not have my phone and camera so was mainly upset because I already had taken lots of photos and then would not be able to take any more photos for my other days in this new area for me which was Yosemite. There was still an hour or so of daylight so I went back on the trail looking for was the area and did some in the woods searching but found nothing. Later as I was laying in my tent I realized I was also missing my rental car keys. It seems I had taken my backpack from the bathroom area but left the waist belt pack. I was starting to mentally panic but did realize I had tracked the entire hike on my Garmin Fenix 6 watch but had never looked at a route on thae watch. I played with the watch trying to figure out how to have it show me where I had gone into the woods but could not figure it out. I believe I have learned track back only works before ending or saving a route.
The next morning after breakfast I went looking again knowing I was in a wooded rather flat area and most of the area north of Little Yosemite Valley is rather open and hilly. Using what I know as a basic principle of search and rescue of going in a ways and them coming directly out and moving over some and going in again and repeating this method I found the pack only after a few tries so saved my trip.
Sorry for the long story but I am commonly by myself and for future safety I wonder how could I have found my lost keys or phone in airplane mode. Is there a way my watch could have guided me. Is there some other device that could have guided me from a saved route. When I got home I looked online at my route and easily saw where I entered the woods.
Also on a related subject how do others carry items such as wallet and car keys in or on their packs.
