The Barryvox indicates you the first axis of the fine search,
refered to as the “runway” in the “Airport Approach” teaching
model.
For novice companion rescuers, it is usually faster to proceed
with the probe once they have found to lowest distance indica-
tion on the first axis.
For intermediate and advanced users, it is advised to apply a
classic grid search pattern.
Searching in a strictly perpendicular cross shortens the search
time and increases the search precision, thus always try to
keep the device and your body in the same orientation during
fine search.
The greater the remaining distance to the buried subject (burial
depth), the more repetitions of fine search crosses may be
required to reach sufficient search-precision. Systematically
fine search until you have found the point with the lowest
distance indication.
Immediately place an indicator, i.e. a ski pole at this spot
as an important reference when applying the probing spiral.
Open your backpack now and assemble probe and shovel. It is
recommended to put your backpack immediately back on your
shoulders, in particular if you use a back pack with an airbag.
In the unusual case of a secondary avalanche, this allows you
to take advantage of the safety gear. By strictly keeping the
equipment (i.e. first aid kit, radio or mobile phone) with you
in your back pack, you will always have it available when you
need it while rescuing the subsequent buried subjects.
