My buddy in Denver swore by his old Garmin GPS for hiking, even with phones around.
We were on a trail near Boulder last fall and his phone died. He pulled out this ancient Garmin eTrex 20, said he'd had it for 8 years, and it still got a lock in under a minute. He just shrugged and said 'batteries you can swap beat a dead brick every time.' Anyone still use a dedicated GPS unit, or is that totally pointless now?
