Mammut Pulse Barryvox
This three-antenna, dual-platform beacon is a digital/analog hybrid that can be programmed for basic or advanced users. Features in the advanced user platform include a vital-data display that indicates the number, relative distances, approximate locations, and survivability ratings of multiple burials. It also comes with W-Link technology, which allows searching beacons to communicate with and share info—such as located victims—with other W-Link compatible beacons. [$490; mammut.ch]
Arva Link
The Link is Arva’s W-Link-compatible option. Like the Pulse, it has simple and advanced modes (with personal programming options), a marking function for multiple burials, digital/analog processing, and a new motion detector that protects a searcher in the event of a secondary slide: If there is no movement for more than four minutes, the unit automatically switches into transmit mode.
