Search for Multiple Buried Subjects
The transceiver attempts to analyze all the detectable signals
and to determine the number of buried subjects. This is
possible because the signals from each transmitter have
characteristics which are distinguishable from the signals of
other transmitters. The more unique the signal characteristics
are, the more accurately the signals can be distinguished and
separated (pattern recognition). By automatically associating
the signals with their respective sources, multiple burial situ-
ations can be solved without applying special search tactics.
Transceivers which also transmit W-Link information can be
detected particularly fast and reliably. The W-Link information
includes a unique identification as well as the trasmit pattern.
List of Buried Subjects
The buried subjects whose transmit patterns can be identified
are inserted in the list of buried subjects based on their signal
strength, usually corresponding with distance. The closest
buried subject on the avalanche is shown at the bottom, the
furthest at the top of the list. The list of buried subjects can
show no more than 3 buried subjects at the time. In case the
amount of recognized buried subjects is greater, arrow symbols
indicate that the list contains further down or further up in the
list additional entries. Usually, the device guides you so that
the list is processed from bottom to top. The lower, already
hidden part of the list of buried subjects . contains therefore
the buried subjects which have already been marked as found,
and the upper, not yet visible part of the list , the buried
subjects which are not found yet and still ahead of you on the
avalanche.
Independently of the position of a buried subject in the list, the
device will always try to guide you as quickly as possible until
all recognized buried subjects are found.
Limitations
The larger the number of buried subjects, the more difficult
and time-consuming the exact analysis of the situation gets,
because of overlapping signals. The more signals there are, the
longer the signal overlaps can last. The capability to automati-
cally detect and isolate signals from multiple buried subjects is
therefore limited.
