its electronic compass is no longer accurate. What’s wrong? a) The compass automatically turned off when the batteries were changed. Go to the setup menu and turn it back on. b) The compass went out of calibra- tion when you changed batteries. You must recalibrate the compass. c) Electrical wires are attracting the needle. Move to a different place and try again.


8 You must arrange a medical evacuation, but your camp cannot be seen from the air. You have a GPS device and satellite phone. To make your coordinates as accurate as possible, you should: a) Keep the GPS device on for a full five minutes. The last reading will be the most accurate one. b) Turn on “position averaging.”


Let the unit run for a few minutes before you take the reading. c) Allow the unit to obtain a fix, and then turn it off. Wait one minute and turn it on and take another fix. Do this three times. The last reading will be the most accurate.


9 You want to email the UTM coordinates of a waypoint to a friend. Which one of these should you send? a) Nad 27 / 0628250E / 5291800N b) U 0628250E / 5291800N c) Nad 27 / 13U 0628250E / 5291800N d) 13 0628250E / 5291800N


10 The batteries in your GPS unit


are low. What can you do to con- serve power? a) Read the GPS unit bearing to your objective then turn off the


GPS device. Set the bearing on your needle compass and follow it. Turn on the GPS device briefly if and when you need an updated bearing. b) Turn on “simulation” or “demo” mode. Your GPS unit already has enough satellite information to provide updated fixes as you move toward your objective. c) Nothing. That’s why you should always bring a compass and map!


11 Your topographic map was last


updated in 1963. Which of these would make a poor GPS waypoint? a) The junction of two trails b) Where a creek runs into a river c) A high hill d) A prominent rock outcrop ¿
