From the manufacturer

The PIEPS PRO IPS is a state-of-the-art avalanche transceiver for professionals and ambitious ski tourers. Thanks to IPS technology, it minimizes the effects of interference in send mode and ensures a particularly stable signal transmission. With a search strip width of 80 meters, Dual Antenna Signal Processing for maximum precision and practical functions such as Scan mode, Auto Search-to-Send and Ghost Signal Elimination, it sets new standards in avalanche safety. Its robust design, long battery life and Bluetooth connectivity make it an indispensable companion in alpine terrain.

Features

Other Features

• Scan Function
  Keep track of everything! This feature provides a quick overview of the situation in a multiple burial situation and displays the number of buried persons in a specific distance intervals.
  
  
• Auto Antenna Switch
  Always uses the antenna with the strongest signal.
  
  
• Victim Selection
  Create a situation-optimized search strategy! In detailed SCAN mode, the transceiver displays direction and distance for each burial to enable a targeted rescue strategy.
  
  
• Ghost Signal Elimination
  PIEPS’ sophisticated signal verification only displays signals from avalanche beacons and no “ghost signals” from other sources.
  
  
• Auto Search-to-Send
  In the event of a secondary avalanche, the avalanche beacon automatically switches from search to send after a certain period of inactivity (motion sensor does not register movement).
  
  
• Group Check Pro-Mode
  Check like a PRO! Efficiently verify that the beacons in the group are transmitting and receiving correctly.
  
  
• Deep Burial Recognition
  The PRO IPS is capable of detecting and indicating deep burials over 2m.
  
  
• Inclinometer
  The inclinometer function shows the steepness of the terrain.
  
  
• Backup Mode
  Backup Mode is intended for rescuers in passive search tasks, like probing or shoveling. Here, the Backup Mode mutes the “SEND” signal when device is in SEND position so other searchers can focus on the signal of the buried victim. Transmitting (sending) automatically resumes when no movement is detected for a predetermined time (the Auto-Revert timeout), preceded by a 30 second countdown.
  
  
• Advanced Search Control
  Visual, acoustic and haptic support during the search. Prompts for reversal in case of wrong direction approach (180° error).

Range Definitions

Circular Receiving Range

PIEPS devices have a so-called “circular receiving range”. This means that the X and Y antennas are equally strong during the coarse search (max. 10% power difference in the best coupling position).
This almost circular reception characteristic leads to a simpler and more efficient coarse search. With antennas of different strengths, on the other hand, an elliptical reception characteristic results, which means that the device has a shorter reception range to its side than to the front or rear.

Useful Range

With Useful Range, we specify the range at which a constant signal can still be received even in the worst case, i.e. with the most unfavorable coupling position between the transmitter and the search device.

Search Strip Width

The search strip width indicates the range that counts in an emergency. How wide can I choose my search section to be sure that I will locate the buried victim(s) if they are in this area?
The search strip width we recommend is double the USEFUL RANGE. Double because this range covers two directions. This means to the front and to the rear, as well as to the left and to the right. With a recommended search strip width of 60 m, you can therefore pass through the middle of an avalanche cone with a width of 60 m, as you have a range of 30 meters to the left and right. As our recommended search strip width is based on the USEFUL RANGE, we also cover the most unfavorable scenario.

Max Range

Specifies the range from which stable initial reception is possible in the best coupling position. For us, stable initial reception means that 8 out of 10 pulses are correctly detected.
