I need some help and some education on a good GPS. I'm in the process of buying gear for my first DIY backpack elk hunt in Colorado. I have never needed a GPS for the hunting I have done in South Dakota, so I'm looking for some guidance. What's a good quality GPS that won't break the bank, but have most of the desired features needed for backpack hunting? I want it to be capable to use a chip like HuntGPSmap to keep me in the correct unit and off private ground. So what do I need to know and what would you suggest? Thanks!
