Garmin. Any Garmin you can find for under $200. And don't make it your main tool for navigation either. Bring along a good set of topo maps of the area and a good reliable compass. Know how to use both before heading out. I never rely soley on my GPS, ever!
I have the garmin legend hcx with topo maps loaded into it it came with a case a sd card and topo maps it's simple to run and batteries last a long time in it as stated above get a topo map of the area you are hunting it allows you to see a larger area at one time than the gps the screen is about an inch and half square
I've been using the basic model Garmin Rino, which last I checked was still under $200. It's got a built in radio and you can transmit your position to other Rino users, which it then displays on the map. But the basic Garmin line is about all I've used in my professional and personal adventures since the mid 90s.
I learned this the hard way last year. If you're hunting in an area with lots of bear activity, it's a great idea to stash your food and water up in a tree. I like to wrap everything in a tarp and tie it between two trees. Don't just tie it up in one tree but tie it in between two trees at least 15 feet in the air. I thought I had my backpacking camp's food supply stashed pretty well last year. I returned to camp during the first weekend of archery to find all my food destroyed. Make sure...
