| Still needs | Practice, probe, shovel, training |
The Barryvox is Mammut’s well-known line of avalanche transceivers (beacons) used to transmit and search for signals during avalanche rescue. A modern three-antenna digital beacon operating on the standard 457 kHz frequency, it’s a popular choice among backcountry travelers — but like any beacon, it’s only effective with practice, partners, a probe and shovel, and avalanche education.
This is general educational information, not avalanche training.

Frequently asked questions
What is the Barryvox?
The Barryvox is Mammut's family of avalanche transceivers (beacons). Worn in transmit mode in the backcountry, it broadcasts the standard 457 kHz signal, and switches to search mode to locate a buried partner's beacon during a rescue. It's a widely used, modern three-antenna digital beacon.
Is the Barryvox a good avalanche beacon?
It's a respected, capable transceiver with the standard features expected of modern beacons — three antennas, digital display, and multiple-burial functions. As with any beacon, what matters most is that you practice with your specific device until its use is second nature, since the brand is far less important than your skill.
Does the Barryvox replace avalanche training?
No. The Barryvox, like any beacon, is only one part of a rescue kit (with a probe and shovel) and is useless without practiced skill, partners who also carry gear, and the judgment to avoid avalanches in the first place. Formal avalanche education is essential regardless of which beacon you own.
