User Manual
Situation: Two avalanche victims are carrying avalanche transceivers without Pieps-
Support. Two rescuers equipped with the Pieps safety system (Pieps Freeride; iProbe
transponder; Pieps “Tour” shovel). At rst the rescuer has no initial detection.
• Rapidly patrol the search area using the recommended search strip width.
• As soon as they are in the reception zone of both transmitting avalanche
transceivers, the symbol for multiple burial appears on the display.
• Only the strongest transmitted signal is shown on the display
(approximate distance from nearest victim)
• With the aid of the dynamic eld direction display, quickly follow the eld
line to the rst victim. If the indicated distance increases, turn round 180 °.
• Point location is aided by the dynamically responding audio output.
• Depth measurement: the iProbe’s acoustic and visual target display
conrms “on target”.
• The Pieps Freeride’s digital technology aids searching for further transmitted
signals and their maxima with the aid of the “3 circle method” or “micro
search strip method”.
• Whilst the search for the second victim commences,
the second rescuer begins digging with a view to rst aid.
• Point location, depth measurement, digging out and recovery of the
second victim.
MULTIPLE BURIAL
IMPORTANT! With avalanche transceivers that receive by means of one or two
antennae, up to 3 maxima (3 indicated distance minima) are possible.

IMPORTANT! Only a high-specication triple antenna system as used in
the PIEPS DSP consistently yields a single maximum on the display during
point location by virtue of its three-dimensional reception zone. The smallest
indicated distance is the shortest distance to the victim.
Vertical transmitter:
Two maxima (right and left).
Horizontal transmitter
in the event of deep burial (>1m):
Three maxima (right, left and
above the victim).
Tilted transmitter:
Two maxima (right and left)!
