Operating Instructions
Shoveling
Shoveling is difficult and consumes the majority of time during an avalanche
rescue. For best results, start shoveling at least one step downhill of the
probe (Figure K). Make sure your hole is at least one "wingspan" wide.
If there is enough manpower, then in burials of one meter or less, both
shovelers should be digging near the probe. In burials deeper than one
meter, one person should dig near the probe with others downhill, to move
snow away from the hole.

Multiple Burials

When more than one transmitting victim is within the receiving range
of a Tracker, the multiple burial icon will illuminate and stay solid.
(Note: this icon can occasionally illuminate irregularly in the presence
of electromagnetic noise or when detecting older analog transceivers).
If there are more than two transmitting victims within range, then the
"+" icon will illuminate.
If the multiple burial icon is illuminated and/or the Tracker displays more
than one distance and direction, then there are probably several victims
within range. Stay in search mode and focus on the closest distance
reading, attempting to engage that signal in the center search light.
Once you are significantly closer to one signal than the other, the Tracker
will "lock" onto that signal and mask out the others. Once this signal
is isolated, Tracker will behave very similar to how it does in a single
transceiver search. Once you have located and excavated the first victim,
turn his or her transceiver off if you determine the conditions are safe.
If you have a clear signal, then begin searching for the next victim.
If it is not possible to turn off the first victim's transceiver—and you have
enough people to begin shoveling—then we recommend isolating the
next signal using Signal Suppression.
