Before GPS, I had a compass mounted to my sled. Saved me many times, come to a three-way intersection, not sure which way to go. I knew the right way on the map was northeast mostly so I'd start going that way for a few miles and as long as the compass was right... It usually workout out. I always carry Maps just in case. My GPS has frozen in super cold Temps and won't stay on for more than 15 seconds at best. I've been thinking to get another compass but the Imotoniege app should solve that problem. As long as it's charged... LOL
