Multiple Burials
If you begin to receive more than one set of signal data, you
probably have several victims within your receive range. Stay in
search (SE) mode, and focus on the closest distance reading,
attempting to engage that signal in the center search light. If you are
roughly the same distance from both transmitters, the Tracker will
often flash “SE”.
Once you are significantly closer to one signal—and within about
ten meters of it—the Tracker DTS (in SE mode) will “lock” onto that
signal and mask out the others. Once you are locked in, the Tracker
will behave very similar to how it does in a single beacon search.
Pay attention to the readings you last received from the other
beacon; they will give you an indication of where to go after finding
the closest one.
Once you have located the first beacon, turn it off if you determine
the conditions are safe. If this is not possible, you might already have
a good idea of where beacon 2 is located. In that case, move in that
direction until the Tracker isolates that signal.
Special Techniques
In most cases, multiple burials are approached as a series of single
burials. However, special techniques might be helpful if the victims’
beacons cannot be turned off and there are several rescuers
available (so some can start shoveling while the best beacon user
continues searching). These techniques are only necessary for
close-proximity situations, where two or more victims are suspected
to be very close to each other. If the victims are located less than
about five meters from each other, then it is possible to move past
a signal without it being detected. If the victims are suspected to
be further apart than this, then it is quite simple to continue on your
signal search until the second victim’s signal is captured and isolated
by your Tracker. In the case of suspected close-proximity multiple
burials (with more than one rescuer available), we suggest the
following special techniques:
Three-Circle Method: This technique involves remaining in SE
mode and making concentric circles around the location of the first
victim until another signal is detected. It is most effective in large
deposition areas and low-angle terrain.
