PINPOINT SEARCH:
The triple antennae
system of the d3 facili-
tates a precise pinpoint
search.
During the pinpoint
search at a distance of
2 - 0 m the digital direc-
tion arrows are swit-
ched off. This indicates
to the searcher that he is
very close (approximately
2 m) to the victim.
Now pass the d3 over
the snow pack at a
distance of several cm.
IMPORTANT:
At this point stop
turning the d3.
Under 2m:

Pinpoint search is carried
out with the help of the
digital distance reading
and the increasing fre-
quency of signal tones.
The victim is located at
the position of the lowest
display (= buried depth).
Use the avalanche probe
as an orientation aid for
rescue with the shovel
and shovel laterally away
from the probe!
STRATEGIES FOR
SEARCHING FOR
MULTIPLE VICTIMS
(SIGNAL SEPARATION):
90° METHOD
Use of, compliance with,
and consistent execution
of the selected search
strategy is crucial for the
success of the search!
The signal display by the
red LED (12) on the d3 is
an important aid in recog-
nizing a situation with
several victims. The red
LED lights up if several
persons have been buried
in the reception area. If
the constant light begins
to flash then the second
victim is less than 10 m
away. The red LED is illu-
minated approx. 5 se-
conds after activating the
receiver. If several signals
overlap, this process can
take up to 20 seconds. If
a group needs more than
5 seconds to switch to
the receive mode then the
display can be switched off
by briefly switching the d3
