Probing/Pinpointing
At your lowest distance reading, probe in concentric circles, with each
probe hole about 10 inches (25 cm) apart. Your probe should enter the
snow perpendicular to the slope. Once you have confirmed the victim's
location, leave the probe in the snow.
Shoveling
Shoveling is difficult and exhausting and consumes the majority of
time during an avalanche rescue. For best results, start shoveling
just downhill of the probe. In burials deeper than 1 meter,
excavate downhill about 1.5 times the burial depth, at least one
"wingspan" wide.

Multiple Burials

Complex multiple burials are quite rare in recreational settings
and usually can be treated as a series of single burials. For more
information on multiple burial search techniques, see page 12.
6
Objective: Locate signal
•If no "last seen point," search entire path
•Rotate Tracker horizontally
•Max 40m between searchers or switchbacks
40m
20m
Objective: Move quickly to 10m,
slowly to 3m
•Keep flashing light within center 3 windows
•Move quickly in direction Tracker is pointing
•Make sure distance is decreasing
•Slow down at 10m
Objective: Locate smallest distance reading
(strongest signal)
•Use Tracker close to snow surface
•Ignore fluctuations in distance and direction
•Begin probing at lowest distance
•Probe in concentric circles 10in (25cm) apart
