Bush Search and Rescue uses Garmin eTrex GPS units.
NOTE: These have now been superseded by the Garmin Vista HCx
Some quick hints for using these are:
To obtain your current grid reference
Hold in the ENTER button for 2 seconds. A grid reference will appear at the bottom of the MARK WAYPOINT page. It should appear in the same format as this example:
55 H 0328315
To obtain a six figure GR as typically used with maps, simply use the three digits in the middle. In the above example the 6 figure grid reference is 283 189.
Storing your location as a waypoint
Press and hold the ENTER button for 2 seconds. This takes you directly to the MARK WAYPOINT page. The screen shows you at your current location. Note or edit the waypoint number. Press the ENTER button to store this location.
Storing a waypoint for another location
Press and hold the ENTER button for 2 seconds. This takes you directly to the MARK WAYPOINT page. The screen shows you at your current location.
Press the button to move the cursor over the grid reference. Press the ENTER button to edit the current grid reference. Use the up and down buttons to move over each character and press ENTER to begin editing them. Change the characters you need to set the new waypoint.
When you have set the new waypoint details, press OK to return to the MARK WAYPOINT page. Take note of or edit the Waypoint Name that appears towards the top of the screen. Press OK to store the new waypoint.
To navigate to a waypoint
Go to MENU WAYPOINTS. Press the Up or Down button and highlight the alphabetical tab containing your desired waypoint. Press ENTER. Press the Up or Down Button to select the desired waypoint. Press ENTER. Select GOTO on the Review Waypoint page and press ENTER
Then press the PAGE button to return to the POINTER page. Press the UP DOWN button until Bearing appears. This is the bearing to your desired waypoint. A small "m" after the bearing indicates it is a magnetic bearing.
To turn off the unit, press and hold the PWR button for 2 seconds.
If you are in a screen you don't want to be in, simply press the PAGE key until you return to the top-level menu. The PAGE key acts like the Esc key on a standard PC keyboard.
