4.4.3 Search for Multiple Buried Subjects

Using the Standard Mode

In standard mode, the transceiver attempts to analyze
all the detectable signals and to determine the num-
ber of buried subjects. This is possible, because all
the signals from one transmitter display characteris-
tics, which are distinguishable from the signals from
other transmitters. The more unique the signal char-
acteristics are, the more accurately the signals can
be distinguished and located (pattern recognition). By
automatically associating the signals with their
respective sources, multiple burial situations can be
solved without applying specific search tactics.

List of Buried Subjects

The buried subjects are listed based on the dis-
tances.

Procedure

1.
The device favors the closest subject first. Locate the
various buried subjects using the transceiver and
probe pole (Chapter «Search for a Single Buried Sub-
ject using the Standard Mode»).

2.
As soon as you mark an individual subject, the trans-
ceiver takes you to the nearest, unmarked buried
subject.

3.
Continue this procedure until all subjects are located
and marked.

4.
The rescuer now searches for additional buried sub-
jects while the display shows the symbol for the pri-
mary search phase

to indicate that the rest of the

avalanche surface must be searched (Chapter
«Primary Search Phase»).
