BE GPS COMPETENT
Know how to use GPS correctly before you head into the backcountry. Practice until different options become second nature. As backup, carry extra batteries, a map and compass!
Set Up
Your GPS
Use the proper datum or coordinate system for your map, which you should also take on your outing. Learn to use the UTM Coordinate grid used on snowmobile, USFS and USGS Quad maps.
Create
Waypoints
Create and name your waypoints - your present location (e.g. car, trailhead, trail junctions). Create other waypoints by entering coordinates and giving them a name or identifier.
Share
Your Plan
ALWAYS share your travel plan with others:
-
Your mode of travel
-
Where you're going
-
When you'll be back
-
Change of plans, if any
-
Who/when to call 911
-
Who's in your group
-
Everyone's contact info
Get There
and Back
Determine your bearing and distance to any given marked waypoint. Set up your GPS to record your track and retrace it.
Carry Extra Batteries
Keep extra batteries warm in a pocket; consider lithium batteries in very cold weather.
