Mammut Barryvox Avalanche Beacon Black One Size — Triple-Antenna Transceiver, 70m Range for Skiers & Splitboarders

The Mammut Barryvox Avalanche Beacon is an intuitive, triple-antenna transceiver that gives clear distance, direction and victim count for fast, confident backcountry rescue.

Designed for skiers and splitboarders who spend time beyond groomed runs, the Barryvox simplifies avalanche search procedures with a straightforward control layout and a goggle-friendly screen. Its triple-antenna design supports a digital signal range up to 70 meters, while automatic mode switching and built-in group checks help reduce human error during high-stress situations. Included alkaline batteries and a snug carry case mean the unit is ready to wear close to your chest straight out of the box.

How does the Barryvox make avalanche search faster and clearer?

The Barryvox provides immediate visual guidance showing relative distance, arrow-based direction and how many buried transmitters are detected, helping your team prioritize targets. The display is easy to read with goggles on, and the electronics are tuned for quick reacquisition.

• Clear distance readout in meters for fast closure
• Directional arrow and signal strength indicators for efficient movement
• Victim-count display to manage multiple burials
• Goggle-friendly contrast and large digits for low-light use

What controls and features make it simple to operate under stress?

Mammut focused on straightforward ergonomics: a single switch, one main button and a dedicated flagging key reduce confusion during drills or real rescues. Group and self-test routines are presented with clear instructions so you can confirm functionality quickly before heading out.

• Single-switch mode selection for send/search/receive
• One-button operation for searches and confirmations
• Separate flagging button to mark located victims without switching modes
• Visible, guided group and self-test prompts for pre-trip checks

How reliable is the Barryvox in real-world backcountry use?

The Barryvox combines a robust triple-antenna receiver with a 70-meter digital range comparable to high-end transceivers, improving hit rates in complex burial scenarios. An automatic safety feature reverts the device to transmit after four minutes of no movement in search mode, protecting you if you’re immobilized while assisting others.

• Triple-antenna reception for better signal stability and reduced null zones
• Up to 70 meters effective digital range for wider search coverage
• Automatic switch back to send after four minutes of inactivity in search mode
• Supplied alkaline batteries and a low-profile carry case for reliable, ready-to-wear setup

How does the Barryvox fit into my avalanche safety routine?

Use the Barryvox as your primary transceiver during backcountry tours, combining it with shovel, probe and practiced companion-rescue skills. Regularly run the group test, carry spare batteries, and train with the unit so muscle memory complements the device’s intuitive interface.

• Perform group and self tests before every outing
• Carry spare alkaline batteries and check contacts periodically
• Practice multi-victim searches and flagging drills with partners
• Wear the supplied case close to the chest for consistent antenna orientation
