Search methods
■ Final search (detecting phase)
When you reach this number, with the arrow lit, lower the device horizontally, in
the same position, to just above the snow. The beeps quicken, and the search
number falls further.
Continue progressing to the smallest number. When it begins rising again, return
to the lowest number and locate the victim using the cross technique, keeping the
device in exactly the same position (parallel to snow).
During this phase, each time you obtain the lowest distance, the device must
always point in the same direction (do not turn it to the left or right).
With an ARVA, you don't need to an extremely precise location. It is often quicker
to immediately start probing once you have defi ned the like location zone to about
50 cm precision.
Marking a nearby signal
When the progress indicator falls to 3.0, the device offers to mark (i.e. mask)
the detected signal. Pictogram
mark the signal once you have pinpointed/touched the victim with the probe.
By pressing the centre button, you mark the nearby signal received. The device
then locks onto the next nearest signal
to the current searched-for victim, and the found/marked victim is replaced by
this pictogram . Then continue searching until the fi nal-search phase.
Once all the detected signals have been marked, the device reverts to analogue
mode and invites you to check the entire avalanche by displaying the X sign.
NB: The marking mode works in most cases. However, some signal stacks are
hard to separate, and multiple burials (more than 4 signals) reduce the searcher's
ability to mark the signal. An alert message " " may appear.
Move away and try again. Or, to increase your chance of success, proceed using
the three-circle method or the micro-strip search method.

1.0 Scrolling between victims
In the victim list created on the left of the screen, the searcher can scroll between
victims to evaluate distance to, and direction of, the detected victims. This also
allows multi-search rescuing, and guiding of people with less effi cient DVAs.
Change victim by pressing on the left- or right-hand button
moves to the detected victim, and gives you this victim's distance and direction.
By default, the device will lock onto the nearest victim.
