For distances closer than 5m, the search speed should be reduced to a maximum of one step per
change in display (between 0.5 and 1.3 seconds depending on avalanche transceiver model). At an
distance indication less than 2 m, carry your PIEPS Freereide in search mode right on the surface of
the snow. The dynamically responsive audio output (the nearer you get, the faster it sounds) aids
with locating the point.
imporTANT! While pinpointing, don't make any fast movements (20-40 cm/sec). During the
entire point locating procedure, hold the device level in the same position without rotating it and
as close as possible to the surface of the snow.
Continue moving in the most recently followed direction until the indicated distance begins to
increase again. Mark the point of minimum indicated distance ("maximum 1") with a glove for
example and continue in the marked direction (3m-4m) looking for any further maxima. If there are
no further minima of indicated distance along this axis, return to the marked maximum 1 (glove) and
try to determine the minimum distance by executing repeated cross scans separated by 90 degrees
in each case. If during cross scans in the four possible directions the distance should reduce further,
then continue in this direction until the distance starts to increase again (mark maximum 2 with a
glove) and start again with the cross scanning described earlier. Again continue 3-4m along the same
axis searching for any further maxima. Continue with this procedure until no further reduction in
distance can be detected.
imporTANT! Practice your preferred search method. This
is the only way you gain valuable seconds or minutes in the
event of an emergency companion rescue.
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 spec 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.

1) Situation: Two avalanche victims are carrying avalanche transceivers without iproBE-Support.
Two rescuers equipped with the pIEpS safety system (pIEpS freeride; pIEpS iprobe; pIEpS "Tour"
shovel). at first 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 field direction display, quickly follow the field line to the first
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 confirms "on target".
Leave the probe in position!
• 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".
• While continuing the search for the second victim, the second rescuer begins digging
with a view to first aid.
• Point location, depth measurement, digging out and recovery of the second victim.
