Voluntary recall: Mammut Barryvox 2 and Barryvox S2

Mammut is recalling the new Barryvox 2 and Barryvox S2 avalanche transceivers from the 2024/25 winter season. It has been determined that the functionality of the main switch may be impaired in some cases.

The possible malfunction is due to an assembly problem. As a result, the main switch of the affected devices may be misaligned under certain conditions. This may cause the device to accidentally switch from transmit mode to search mode under lateral pressure or even turn the device off completely. This defect may pose a safety risk to users and must be corrected.

After identifying this risk, we immediately checked 100% of our inventory. The inspection confirmed that only the models Barryvox 2 and  Barryvox S2 could be affected. The previous models Barryvox and Barryvox S are not affected.

Fortunately, we were able to determine the cause of the possible error and immediately initiated a damage limitation process to replace the affected devices in a timely manner.

We have a solution for all affected devices. Therefore, we ask you:

• Check if you own a Mammut Barryvox 2 or Barryvox S2. Please use the images and model numbers provided to identify the models.
