1.     GPS Batteries – load fresh batteries and carry extra for both the GPS and flashlight.

2.     Calibrate the GPS receiver’s compass after every battery change.

3.     Magnetic Compass adjusted for declination – Visit www.magnetic-declination.com for the most current declination value.  Declination changes over time (how old is that map?) and location.

4.     Dump the junk – How many waypoints are stored in the waypoint manager file.  Dump the old waypoints to the absolute minimum; this helps to keep navigation simple.

5.     Match the GPS receiver’s compass to the magnetic compass and the map.   .  Maps are usually set to degrees true.  Have the GPS and Magnetic compass match the topo map.

6.     Erase old track data – clean up the old the track (bread crumb trail) information.  Get rid of

the clutter.

7.     Remember to stow the maps.  I use maps from www.caltopo.com and will occasionally carry maps from a hiking guides.  Maps are stowed in a zip lock gallon bag or rugged water proof map case.

8.     Mark a waypoint – Give key waypoints a name like “trl hed” or “camp.”  Select waypoint manager to verify that the information has been saved to memory.  If “trl hed” can be viewed on the waypoint manager file or viewed from the map page the hiker is all set.
