From the manufacturer

The PIEPS MINI IPS is a compact avalanche transceiver that brings advanced PIEPS technology into a highly portable format. With a 50-meter search strip width and Search Assist Plus, the visual search aid with pictographic instructions, it intuitively guides users through the search process. The innovative Interference Protection System (IPS) minimizes disturbances in transmit mode and ensures stable signal transmission. Thanks to its robust design, long battery life, and Bluetooth connectivity, the MINI IPS is a reliable companion in alpine terrain – for both beginners seeking maximum safety and experienced backcountry users who value a compact device with advanced technology. With PIEPS’ industry-leading signal processing quality, it delivers especially clear, consistent, and reliable direction indication in critical situations.

Features

• The PIEPS MINI IPS combines a wide range of functions that make it a particularly reliable avalanche transceiver.
  
  
• The innovative Interference Protection System ensures stable signal transmission in send mode – even in environments with interference – while the dynamic search strip width in 50, 35, and 20-meter steps enables precise interference management during the search.
  
  
• With its compact design and low weight, it fits easily into any designated pocket without being bulky.
  
  
• Search Assist Plus provides pictographic guidance for maintaining the right search speed, while features such as the protected switch mechanism, perfect marking performance, and Auto Search-to-Send deliver additional safety.
  
  
• The MINI IPS is further enhanced by the adjustable Group Check distance (1 m or 3 m), the Switch-off Reminder, and versatile training functions via the PIEPS App.
  
  
• Using Bluetooth, firmware updates can be installed, device settings managed, and a comprehensive app-supported device check performed – keeping the MINI IPS always up to date.

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.
