Garmin E Trex 30 User manual

Using E Trex 30 for Crashed Model Location.
Basic Concepts
Immediately after the crash memorise the direction of the crash and esti-
mate the distance into the bush. (Lay your Tx on the ground with the an-
tenna pointing in the direction of the crash)
To help distance estimation the following will assist:
 Length of Runway: 200 m
 Distance from the pilots station to the cabbage trees opposite: 168m
 Distance from the pilots station to the Astro dome: 275m
Both these features and the pilot station have been entered as way
points in the E Trex
Stand at the pilot station, Start up the Etrex, from the MENU page select
the Sight ‘N Go feature. Enter the crash direction and its distance esti-
mate. This creates a numbered waypoint, which is the crash site. You can
name this waypoint if required, otherwise remember its ID Number.
Press the “save” selection which brings up the compass page to allow-
navigation to the crash waypoint.
You can then use the compass display or the map display to guide you to
the crash waypoint.
The top pointer on the compass is the COURSE POINTER which points in
the direct bearing to the crash and the “dashboard” data fields tell you how
far away you are.
If you have to deviate from the direct course (e.g. to avoid an obstacle) the
course pointer always indicates the direction from your current position.
A course deviation indicator (CDI) also provides a indication of right and
left drift from the original direct course from the pilots station. If you want
to follow a direct line to the crash the CDI helps you to do this.
If you select the map option the map shows where you are in relation to
the pilot station and the crash waypoint and also points to the crash way-
point.
The tracking feature of the GPS will show your track on the map display
as you make diversions etc on the way to the waypoint.
Use the tracking feature to search closer or further away from the pilots
station in the bearing line of the crash waypoint.

Starting the E Trex
As the various items are highlighted they turn blue
The thumb stick action takes a bit of getting used to. Its easy to move off the wanted
item as you press the thumbstick to select it.
You could use Mark Waypoint to mark where you are in the bush. If you don’t give it a
name you will have to remember its ID number for future reference.
Don’t delete any waypoints. You may accidentally delete an important one.

This is the method to enter the crash
site.
From the Menu Page
Carefully press the thumb stick down.
A click indicates correct action.
Units of measure are metres
The “Dist to next” panel shows how far
you have to go.
Turn the Etrex horizontally until the line
points directly in front of you. This is
the direction to walk.
The next page explains how this
works.
The display now shows the com-
pass and you can start navigating
to the crash. Turn the Etrex hori-
zontally until the arrow is pointing
towards the top of the screen. This
is the direction to move.
If required press menu until the
main menu shows and then select
Map.
The display will show you the
crash waypoint with a magenta
line showing the way to it from
your presents position.
Periodically stop and check your
position and then readjust your
direction of movement
If you want to return to the com-
pass just press menu and then se-
lect Compass.
