I got lost a few years back...4 hours later and a long tough hike, I finally made it back to vehicle. I now depend on my GPS. I personally have a RINO 120. It has a 2 way radio as well as GPS.
A good feature to consider is that the unit vibrates. Beeps and tones are not good to have in the woods.
Garmin has some nice TOPO maps as well.
It has some nice features such as weather alert, barometric pressure, and hunt/fish forecast.
