>>356447Determining a heading is another tricky thing with GPS's. If you're still, they'll tell you to go some direction... but that won't always be right.
>Snowmobiling in feb>marked a waypoint and shared that point with a couple others in our group (rescuing another rider's sled he had stuck'd the previous day)>Stop on a hillside to get our bearings, figure out a way across the canyon>Foggy, kinda socked in, snowing but not snowing hard, shitty visibility>buddy takes out GPS, "They're that way">Me: "You sure?">Look at my GPS, look at bearing/range to the saved waypoint we were going for>take out compass, dial in that heading, red in the shed, "That way, 1/4 mile. Your way takes us along the canyon.">"You sure?" Yes, i'm sure. Start walking and tell me if we still need to go that way. Your GPS's compass isn't calibrated, and it doesn't have a GPS bearing since we've been stopped for 10 minutes."GPS's are great tools, but they're not idiot-proof. Practice with it in town, flag a waypoint at the grocery store or other location you know and have it route you there, see where its faults are.
Been thinking about teaching a GPS orienteering class at the snow shows coming up... they have meeting rooms and some people sign up for hour-long courses on topics relating to snowmobiling.
