14.2 Multiple Burials
In the digital search mode, multiple
burials are indicated by the following
symbol:
When this symbol is shown, the speaker is
set to reproduce the analog tones. These
assist you in separating the various trans-
mitters acoustically.
The Barryvox indicates the nearest victim.
Multiple burials are usually detected within
the search strip width, however depending on
the position and distance between the
rescuer and victims the distance can vary
considerably.
Switch off the transceivers of rescued
persons in order to make continued
search easier.
If you are not absolutely certain about the
number of buried victims, you must search
the
whole of the avalanche area
using
the search pattern as described in the section
on the “Primary search phase!”
Procedure on the Avalanche Debris:
Search strategy for multiple burials wide
apart
Mark the point
on the avalanche where
the “multiple burial” symbol is shown or
where
you left the primary search grid
.
Search for the first victim using the infor-
mation on the display and the analog tones.
Once the first victim has been located, you
or other helpers should immediately rescue
the person.
To continue the search for further buried
victims,
return to the point previously
marked.
Carry on searching strictly
following the primary search grid until the
Barryvox indicates another victim.
At the beginning, the transceiver still indi-
cates the already located victim, as it is still
closest to you.
Ignore the indications until
you realise that the transceiver is now
tracking a new victim.
Search strategy for multiple burials
in close proximity
In this case the interpretation of the analog
tones is extremely important. They have to be
interpreted in conjunction with the indicated
distance. Example:
• There is a triple beep and the distance
indication varies between 3.5 and 4.8 m
➾
within a radius of approx. 5 m,
3 victims may be expected.
Treat the situation by searching the potential
area using a “micro search strip” pattern.
The more victims there are and the closer
they are together, the narrower should the
micro search strips be laid over the potential
area. Hold the transceiver in this phase
always in the same orientation close to the
snow surface and concentrate on the increa-
se and decrease of the distance indication,
respectively to the volume of the analog
tones.
In addition, the probe can be used to quickly
locate multiple burials in close proximity.
