4.5 HELPFUL PIEPS BACKGROUND FEATURES
Maximum background support in send mode and search mode!
4.5.1 PIEPS interference protection
•PIEPS Auto-Antenna-Switch | protection in send mode
If the transmitting antenna is impacted by external interference, the other antenna would take over the
transmit function. The PIEPS PRO BT/POWDER BT always transmits with the strongest possible signal!
•PIEPS Signal Verification | protection in search mode
Only a verified 457kHz signal is indicated. The PIEPS PRO BT/POWDER BT doesn´t confuse with ghost
signal indication!
External interference and distance recommendations
All beacons are very sensitive to electrical and magnetic sources of interference. Due to this, all manufacturers
recommend keeping a minimum distance from electronic, magnetic and metallic sources of interference (mobile
phone, radio, keys, magnetic closures, etc.):
Minimum distance in send mode: 20 cm | Minimum distance in search mode: 50 cm

Manual PIEPS PRO BT/POWDER BT | Firmware v1.0 | 08/2018 12 / 22
4.5.2 PIEPS iPROBE-Support
Beacons with iPROBE-support* get automatically deactivated when probing with the electronic probe PIEPS
iPROBE. This prevents signal overlaps and the next-strongest signal is automatically shown on the display of the
receiving beacon. Maximum support in multiple burials!
* Beacons with iPROBE-Support: PIEPS PRO BT/POWDER BT, PIEPS MICRO, PIEPS DSP PRO/SPORT/PRO ICE, PIEPS

4.8.1 In case of emergency
A buried person has the greatest chance of being rescued by an efficient companion rescue. In the event of an
accident, the following applies: KEEP CALM, OBSERVE, ALERT, ACT WITH COORDINATION!
(1) Keep calm & get an overview
•Are there any other risks?
•How many victims?
•Determine the primary search area!
(2) Make a brief emergency call
•EU 112, AT 140, CH 1414, IT 118, FR 15, NA 911
(3) Burial search
•Signal search (eyes + ears, beacon)
•Coarse search (starting with initial signal)
•Fine search (closer than 5 m on the surface)
•Pinpointing (systematic probing)

4.8.2 Signal search
Start searching in the primary search area for the initial signal detection as well as for visual/acoustic signals. The
PIEPS PRO BT/POWDER BT has a circular receiving range that allows a correct indication of direction and distance
from the point of initial signal detection –a specific method such as turning/rotating is not necessary. All signals
of the burials that are within the maximum receiving range are received simultaneously.
Walk the search strip width in the search area
quickly. The recommended search strip width
for the PIEPS PRO BT/POWDER BT is 60 m.
The display shows “no signal”.
One rescuer with skis
for signal search

d = search strip width
NOTICE
All participants, observers included, must switch their devices to search mode (or to standby
mode)! Also follow the external interference distance recommendations!
As soon as signals are received, the distance and direction to the strongest signal are shown on the display. The
number of victims located within the receiving range is indicated by the number of human figures.

four or more
Vibra on initial signal detection
The PIEPS PRO BT provides additional haptic support by vibration on initial signal
detection. This lets rescuers focus on the visual surface search during the signal search.

Manual PIEPS PRO BT/POWDER BT | Firmware v1.0 | 08/2018 15 / 22
4.8.3 Coarse search
Follow the directional arrow quickly and check for a decreasing distance reading. Change the search direction by
180° in case of an increasing distance reading.
Turn left
Move straight ahead
Turn right
NOTICE Work calmly and with concentration in search mode.
Avoid hasty movements!
4.8.4 Fine search
From a distance of 5 m, the search speed should be notably reduced (50 cm/s). At the same time, start working
close to the surface of the snow. To prevent confusion during the fine search, the direction indication disappears
below a distance of 2 m. Reduce the search speed again and find, by cross-like movements, the position of the
lowest distance reading. A dynamic acoustic signal output supports the fine search: the closer the higher/faster.
Do an accurate direction adjustment before the
direction arrow disappears! You are then moving to the
transmitting beacon in best coupling position and save
time during the cross-like movements.
Move your beacon at a slow, steady speed of about 10
cm/s, keep it leveled close to the surface and do not
rotate your device. Search along the Y axis, determine
the lowest distance value, then follow along the X axis.
Always move past the point of the lowest distance to
verify the distance tendency. Mark the point of the
lowest distance reading and start pinpointing.

Manual PIEPS PRO BT/POWDER BT | Firmware v1.0 | 08/2018 16 / 22
4.8.5 Pinpointing
Begin at the point of the lowest distance indicated.
Always probe perpendicular to the surface. Use your
lower hand as a “probe guide” to ensure the probe
follows a steady path. Follow a proven system until you
have a hit. Communicate a hit clearly to companions.
Leave the probe stuck for shoveling guidance.
4.8.6 Multiple burials | MARK function
A multiple burial is indicated clearly on the display by the number of small human figures (2G, 2H).
Marking is possible from a distance reading of 5 m and is indicated by the MARK symbol (2E). Press the button
MARK (1D) briefly to “hide” the localized transmitter. A successful flagging is confirmed by a frame around the
human figure (2J). The display then indicates the direction/distance to the next strongest signal inside the
receiving range. If there are no further signals within the receiving range the display indicates “no signal”.
prior to marking
after marking
De-mark a single signal: press the button MARK
(1D) for 3 seconds.
De-mark all: switch to send mode and then back to
search mode. With the PIEPS PRO BT you can also
use the SCAN function for a full reset.
Continuous wave indication | old-device-indication
Old analog transceivers are transmitting a continuous wave in addition to the pulse signal. To keep an impact at a
minimum, it is recommended to step a few meters away after marking such a transmitter.
Signal without continuous wave
Signal with continuous wave
The PIEPS PRO BT/POWDER BT identifies a continuous wave and
supports visually by flashing human figures.

Vibra on initial signal detection: see chapter 4.8.2.
4.9.2 Extended group check & pro-mode
See chapter 4.4.
4.9.3 Mark range settings
In the PIEPS APP device manager the mark range can be changed from 5 m (default) to 20 m or to max. range.
4.9.4 Inclinometer
You can use the integrated three dimensional inclinometer to quickly check the gradient:
•Put your ski pole in slope line at that point of the slope you want to measure.
•Press the button SCAN (1E) for 3 seconds while in send mode.
•Put your PIEPS PRO BT next to the ski pole and read the indicated value. The display
switches back to send mode indication automatically after 20 seconds.
DANGER
Risk of device loss during slope angle measurement
Although the PIEPS PRO BT keeps transmitting while the inclinometer is active, the function
should only be used for training reasons. Never use the inclinometer function in avalanche
terrain!
