evo.com | Pieps Avalanche Beacons > The Pieps Pro IPS Avalanche Beacon was introduced last season on a very limited basis among full time patrollers and mountain guides, and went straight to the head of the beacon class. With its 80m search strip and a new Interference Protection System (IPS), along with Dual Signal Processing (DASP) technology, the Pieps Pro IPS blows other top transceivers out of the water. Interference Protection System (IPS) A unique technology that compensates for the influence of electronic and metallic interference to the transmitting device by analyzing and adapting to the interfering source. Users of the PIEPS PRO IPS are better protected against interference from personal electronics and metal items that could otherwise influence transmitting power. Dual Antenna Signal Processing (DASP) The PIEPS PRO IPS processes the signals on both the X and Y antennas simultaneously, a first in avalanche transceivers. This provides a more accurate, faster and more stable indication of the victim/s location.
