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. Do not take shoveling skills for
granted. For best results, start shoveling just downhill of the probe.
Make your hole at least one "wingspan" wide and excavate downhill
about 1.5 times the burial depth (this can be determined by noting
the depth marking on the probe).
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 technique, see page 13.
6
Objective: Locate signal
•If no "last seen point," search entire path
•Rotate Tracker horizontally
•Max 40m between searchers or switchbacks
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
Thank you for choosing the Tracker DTS, the world's first digital
avalanche beacon, and the first beacon with a high-precision
multiple antenna system.
Remember, beacon searches are only part of the avalanche rescue
process. It is equally important to practice the probing and shoveling
techniques found later in this section.
FAMILIARIZATION
Adjustment/Fitting
The Tracker DTS can be worn with or without its harness. The
manufacturer recommends securing it with the harness. When used
with a harness, the Tracker DTS should be worn underneath your
outer garments, as shown in Figure A. Distance/directional display
should be against your body, on/off switch should be exposed and
visible.
To search, remove Tracker from pouch, but keep harness and
lanyard attached to your body. If using without harness, keep
Tracker in a secure pocket, preferably in your pants or other
garment that won't be removed. Attach lanyard clip to zipper or
other solid fixture. If lanyard is removed from harness or clothing for
searching, keep attached to your wrist with loop provided.
