The lightest PLB is about 4 oz which is appealing. Sat phones are a bit heavier and more expensive unless renting. I'm thinking about a PLB partially because my gf is worried and partially because it might just be a good idea if hunting alone in the wilderness. Any thoughts? PLB vs sat phone vs neither (in this case, just tell people where you're going and when you'll be back and when they should call for rescue if you haven't returned)?
