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 12.

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 Tracker2, the world's fastest three-
antenna beacon.
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.
Basic functions
u
On/off: Turn the on/off switch
"on" position (see Figure A). The battery life is displayed in the
v
distance/battery power display
After displaying battery power, the beacon flashes "tr" and enters
transmit mode. The transmit light
transmit pulse. This light will not flash if the battery power is below
20 percent.
Note: that the battery percentage is approximate. The manufacturer
x
suggests replacing batteries well before reaching 20 percent.
Search mode: Pull down the search tab
unit. In search mode, the display will show "SE" and "SEARCH" is
exposed underneath the tab.
The beacon cannot be turned off in search mode. Always return to
transmit mode before turning it off.
Return to transmit: Push the search tab in toward the body of the
beacon until it clicks into place. The display will flash "tr" and beep
for five seconds before it begins to transmit.
After 30 minutes in search mode, the beacon will beep every ten
minutes. After 12 hours in transmit mode, the beacon will beep
every two minutes. These beeps are reminders that there has been
no user input and the beacon is still on.
Adjustment/Fitting
The Tracker2 can be worn with or without its harness. The
manufacturer recommends securing it with the harness. When used
with a harness, the Tracker2 should be worn underneath your outer
garments, as shown in Figure B. 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
