The Barryvox
searches now
for further buried
subjects. The
device leads you
directly to the
next buried sub-
ject or indicates
that the remain-
ing debris need to be systematically searched in a
signal search pattern (chapter «Signal Search»).
Search Tones in Fine Search
In the fine search range, thus in the immediate
vicinity of the buried subject (approx. <3m), the
Barryvox assists you with an artificial, distance and
action related sound while fine searching in a cross
pattern.
For rescuers who can interpret the analog sound, it
is highly recommended to disable this digital audio
support as the more meaningful analog sound will
then be available instead (see chapter “Audio Sup-
port Fine Search”).
Erase Mark
A mark can be removed by selecting the buried
subject with the
-key and selecting «Erase mark»
with the
-key. You can only remove the mark if
you are in the immediate vicinity (< 6 m) of the
buried subject.
Deep Burials
The transceiver tries to detect high burial depth
and, if required, dynamically increases the fine
search range. If a buried subject is marked with a
distance reading above 3 m, an additional safety
dialog appears asking you to confirm the successful
location of the subject. Marking a buried subject in
more the 6 meters depth is not possible. For further
information, please see chapter “No Probe Hit”.
in mind that the remaining distance shown on the
screen indicates the maximum possible distance to
the buried subject. If you see i.e. 1.1 on the screen,
the buried subject must be within 1.1m probing
depth and spiral probe radius. In case there is no
probe hit within this area, you have for sure missed
the buried subject. Repeat probing with a slightly
offset probing pattern (chapter «Pinpointing with
Transceiver and Probe Pole»).
Do not mark the buried subject as found using the
3
-Mark function before you have successfully
located it by a probe strike! Do not hold the device
back to the snow surface to mark!
In case the assisted fine search in a
cross does not lead to success with-
in a predefined timeframe, the fine
search cross will be indicated. Deter-
mine the point with the shortest distance indication
by a systematic, manual cross search holding the
transceiver directly above the snow surface. In this
scenario, the probing indication will not be shown.
Apply the probing spiral at the point of the lowest
distance indication.

Fine search
During this search phase hold the transceiver
directly above the snow surface!
In the assisted
fine search, you will be guided in a systematic
cross search pattern to the point where the further
search is faster and more efficent with a probe.
Keep the device and your body during fine
search always in the same orientation
, when
searching in a strictly perpendicular coordinate sys-
tem shortens the search time and increases the
search precision. The points where the device indi-
cates a change of direction or the final probing indi-
cation correspond mostly, but not always with a
point of lowest distance indication.
The greater the remaining distance to the buried
subject / burial depth, the more repetitions of fine
search crosses may be required to reach a suffi-
cient fine search precision. The device tries to
determine these parameters and guides the res-
cuers accordingly through one or multiple fine
search crosses - until the optimal point to start pin-
pointing with the probe is reached. This spot is indi-
cated by the probe indication
. Immediately place
an indicator, i.e. a ski pole at this spot as an impor-
tant reference with 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 or Avalung. In
the seldom 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.
User Guidance in the Assisted Fine Search
Guidance on the vertical axis
while searching in a cross
Direction indication on
the vertical axis.
Direction indication on the vertical
axis when the deviation point to
the horizontal axis could not be
conclusively determined in the first
search sequence. Reduce the search speed and
repeat the search on the vertical axis by holding the
device directly above the snow surface.
Guidance on the horizontal axis
while searching in a cross
Direction indication on
the horizontal axis.
Direction indication on the hori-
zontal axis when the deviation
point to the vertical axis, respec-
tively to start pinpointing (probing)
could not be conclusively determined in the first
search sequence. Reduce the search speed and
repeat the search on the horizontal axis by holding
the device directly above the snow surface.
Probe Indication
Indication to proceed from fine
search to pinpointing.
Stash the device in search mode on your body (i.e.
pocket) in order to have both hand available to
probe. Apply now the probing spiral, the probe is
applied in a 90° angle to the snow surface. In par-
ticular if the debris are hard, guide the probe with
two hands, one pushing from the top, the other
leading the probe closer to the snow surface in
order to avoid that the probe gets deformed. Keep
