Refresh Your GPS Skills
By
Blake Miller
Now is the perfect time to practice and improve
your GPS skills. Spring hiking, scouting, predator hunts and camping
trips offer excellent opportunities to get “dialed-in” with your
receiver.
GPS will get you back to the truck or help you
return to your favorite spot. Confident use of the receiver comes with
practice and frequent use.
Here are some simple recommendations to try in
the field.
- Dump those old AA batteries, put in new
ones, and replace them again in 4 months. If you leave your GPS on
all day in the field expect to change the batteries nightly.
Consider using lithium AA’s, they last longer and work better in
cold temperatures.
- Verify that you are receiving enough
satellite signals. Check this on the satellite status screen. Four
satellites are the minimum.
- Keep you navigation simple. It’s easier to
work with a handful of waypoints rather than list of 300. Delete
the old waypoints, the ones you will never use again. Log important
waypoints (e.g., the elk wallow) on your PC or in a notebook. Visit
www.easygps.com or
www.garmin.com for a place to store waypoints.
- Give key waypoints names. Enter names like
“camp” and “truck.” It’s easier and more meaningful to find “truck”
in the list of waypoints than is waypoint 542; or was it 245.
- Verify all waypoints saved by either
checking on our map page or in your waypoint file (select “go to” or
“find.”)
- When its time to return to a destination
chose “GO TO” or “Find” on your keypad or menu. Select the waypoint
from the list provided. Press the “Page” button and rotate through
the many displays to the “Compass” page. With a “GO TO” selected, a
large arrow should appear on the face of the compass. As you move
towards your destination the arrow will shift causing you to adjust
your course. When you are on course the arrow points to the top
center of your receiver.
- Compliment GPS skills with a good review of
map and compass fundamentals. Learn to back up electronic position
fixing with bearing triangulation. Worst case, a broken GPS
becomes a paper weight for your map while afield.
I suggest checking out Lawrence Letham’s book
GPS Made Easy from the library. This book compliments the owner’s
manual. An excellent reference for map and compass use is June
Fleming’s Staying Found.
Taking a class can further enhance you GPS
knowledge. Classes are frequently offered through the local community
college’s continuing education program or at local retailers such as
REI.
