I solo alot and considered getting a spot or beacon, I decided against simply because if I was hurt I would wonder what to do after I pushed the button, are they comin, did it work kinda thing. I leave a map on my desk with my route marked and trail notes and when I should be back. My wife knows if I'm not back on time to call authorities in the nearest town.
