The Mammut Barryvox 2 is a compact digital 3 antenna avalanche transceiver with a 70 m range. It guides you through a search with a display and tones, and connects to the Barryvox app by Bluetooth.

What it's for

A transceiver sends a 457 kHz signal while you travel in avalanche terrain and switches to search so you can locate a buried partner. The Barryvox 2 adds protective functions that put rescuers back into SEND if a second slide is a risk.

How it works

Rescue SEND: a mode for rescuers who are not searching. It switches them to transmit if a secondary avalanche buries them

Auto revert to SEND: a motion sensor switches the device back to SEND after 4 minutes without movement

Self test: checks transmission and battery at startup

Interference Guard: manages signal interference and shows it on the display

Group check: confirms the transmit frequency and signal strength of your partners' transceivers

Acoustic guidance: tone sequences direct you toward the buried person

Visual guidance: the display leads you through the search phases and gives an overview of multiple burials

Auto Select: with several burials, it leads you first to the signal it receives at the highest strength

Marking function: mark a located burial and move on to the next signal

Reverse direction function: prevents a 180 degree search error

Bluetooth: connects to the Barryvox app for firmware updates and training

Setup and installation

• Recall check: Mammut announced a voluntary recall on November 8, 2024 for Winter 2024/2025 units of this model. Look at the serial number on the label inside the battery compartment. If it does not start with 24, the device is not affected. If it starts with 24 and there is a green dot in the battery compartment, the device is not affected. If it starts with 24 and there is no green dot, the device is affected and should be sent to Mammut. Inspection or replacement is free of charge.
• Wear: on your upper body in the included Barryvox carrying system
• Before each tour: run a group check
• Training: Avalanche rescue gear only helps if you know how to use it. Get training and practice with your gear regularly. OMG runs AIARE avalanche courses.
