Never been lost. I have always carried a map, compass, and GPS. I started with a Garmin Legend. It got the job done, but wouldn't work under tree cover and you need a compass to use it effectively. It doesn't have a built in compass, so you can't tell which direction your facing when you stop moving.

I've sinced bought a Garmin 60CSx with TOPO maps. This thing not only works under tree cover, it works in the basement of a house. It also has the built in compass.I've never had either of the GPS' go on the "Fritz" as someone else said. But with the TOPO maps loaded in the GPS, you can verify its accuracy by comparing the terrain around you to the GPS topo map.

Even while hunting alone in the Rocky Mountains, I'm confident I'll get back with ease.
