I purchased an InReach Mini to help me be safer on solo backpacking trips. There is a HUGE learning curve to learn how to use the unit, the online accounts to get everything set up, and learn how to use MapShare program which is supposed to allow friends and family to follow me on my trip. Instructions are very user unfriendly and I still don't know how to do all of these things. Maybe it would allow me to be rescued if I am injured (I have not had to test this capability) but other aspects of use are difficult to learn.
