The Arva Neo avalanche transceiver features three antennas using state of the art digital technology to operate as a homing beacon should the wearer be caught and buried in an avalanche, or make locating burial positions as easy and simple as possible.
The Ortovox 3+ avalanche transceiver is simple and reliable for use in single- and two-victim scenarios. On the downside, the Ortovox 3+ offers less accuracy in distance readings over its range than other transceivers we tested, and when there are multiple victims the 3+ can be easily confused.
With their Pieps DSP Pro transceiver, Pieps appears to have traded off a bit of range for improved reliability in multiple victim searches. The marking function is clearly improved, especially in the presence of older, noisy analog beacons.
