Operating Instructions
Fine Search: The fine
search is the final part of
the beacon search, which
is performed on foot with
the beacon positioned at
or near the snow surface.
The objective of the fine
search is to locate where
the signal is strongest
(distance reading is
lowest) and to reduce
the area to be probed.
Move Tracker3 slowly
in a straight line along
the surface of the snow
during the final three
meters of the fine search.
The directional lights do
not illuminate in the final
two meters, so only pay
attention to the distance
readings. From the point
where you have located the smallest reading, "bracket" at 90-degree angles
to the left and then to the right in search of a lower reading (Figure H).
Repeat if necessary along both axes. Begin probing at the lowest distance
reading.
Pinpointing/Probing
At your lowest distance reading, probe in concentric circles, with each
probe hole about 10 inches (25 cm) apart (Figure I). Your probe should
enter the snow perpendicular to the slope. Once you have confirmed the
victim's location, leave the probe in the snow.

Bracketing: Make sure
you go well past the
low reading to confirm
it is the lowest. When
bracketing, ignore the
directional lights, which
no longer illuminate at
less than two meters.
Do not rotate the
beacon during this
process, as it can
change the distance
readings.
