Check your position by Backward Bearing
- The HandHeld TrackMaster can check your position by
backward bearing.
- Spot two distant identifiable landmarks (mountains,
light-houses, forts and buildings) of your current
position, such as the mountain A and B.
- Consult a map to find out the mountain A and B's
locations on a map.
- Check out the backward bearing directions of mountain
A and B of your current position, such as 135

for
mountain A and 270

for mountain B.
- Use a ruler to draw the line 135

on the map which
starting from the mountain A. Draw the lines 270

on
the map which starting from the mountain B.
- Your current position will be at the intersection point
(point A) of the lines 135 and 270.

Measure Compass Directions
- When measuring compass directions, make sure
that the HandHeld TrackMaster is placed on a flat surface
which is parallel to the horizon.
- If you are wearing the HandHeld TrackMaster during
the measurement, make sure that your wrist is
parallel to the horizon.
IMPORTANT: If the watch does not parallel to the
horizon when taking a measurement, the result may
be inaccurate.

the direction where is your target object.
- Press the [compass] button once to select the
Compass Mode, in the Current Time Mode.
- The Compass points of the target object appears on
the 1st row of the display. The digital bearing
direction of the target object appears on the 2 n d
row of the display. The arrow shape indicators on
the display points the magnetic north analogically.
- Rotate the rotary direction bezel until the 'N' mark is
aligned with the arrow shape indicators on the display.
That action makes all of the marks on the bezel in the
correct direction.
