I use a garmin 62 handheld. I also carry a compass… I wear both around my neck on a lanyard. I get my heading off the gps and then put it back inside my jacket to keep it warm, then run the heading on the compass. If I leave the gps exposed, the batteries die quickly. Oddly they come back to life when they warm up. My needs are different than some due to distances traveled on Lake Erie. Once we get close I keep it out. Juast a tip, always point your atv towards home when you park it. We have had guys ride out to open water in a white-out. Get something with the charts so you can fish contours.
