I do a lot of solo backpacking in the great smoky mountains national park. and would like to go on longer trips (most are overnight). Every time I go I worry my family and I am nervous. I am considering buying a spot or a beacon.

I am interested in the spot because my family can track my progress and know if I am running behind or ahead of schedule.
but i have read that they don't do so well under tree cover (which direct sunlight is rare in the Smokies).

I am trying to decide if i should buy a spot or a personal life beacon. Does anyone have any advice
