The digital Pieps Freeride avalanche transceiver is the most compact transceiver available, making it comfortable to wear and travel with while skiing in the backcountry. Freeride uses a single digital antenna to receive signals from transmitting transceivers and has a receiving range of up to 40m. LCD screen displays a flux line indication symbol that helps you align yourself with a flux line when searching for a victim. Screen also shows the approximate distance in meters to the buried transceiver and will indicate when multiple burials exist. Because the Freeride transceiver uses a single digital antenna as opposed to 2 antennas, it cannot automatically point you in the direction of the buried transceiver. Users must use the flux line indication symbol together with audio output and the distance indicator to find a buried victim. In multiple burial situations, the Freeride locks onto the strongest signal and displays the distance to that transceiver. To switch from transmit to receive press the Send/Search button 3 times to switch back to transmit, hold the button for 3 sec. Transceiver can be set to automatically switch from receive to transmit mode after a preset amount of time in case of a second avalanche user must activate this setting. Adjustable harness with pouch keeps the unit secure and accessible. Can be used with the Pieps iProbe not included iProbe can temporarily suppress the signal of a transmitting Pieps transceiver to make searching for multiple burials easier. Compatible with all beacons operating on the 457 kHz frequency. Pieps Freeride avalanche transceiver operates on 1 AA alkaline battery, which provides a minimum life of 200 hrs. in transmit mode 25 hrs. in receive mode.
