WILLISTON, Vermont (Nov. 8, 2024) — Mammut has always stood for quality, safety, and innovation since 1862. The safety and protection of our athletes and consumers are at the heart of everything we do. Hence, we continuously test and improve our materials and products to uphold our high standards. During this process, we identified a potential issue with the power switch of the new avalanche transceivers Mammut Barryvox 2 and Mammut Barryvox S2 in some cases, and we therefore decided to recall all potentially affected products for inspection, and where applicable, repair or exchange.
The potential malfunction is based on an assembly issue. As a result, the main switch on the affected devices may be misaligned leading to unintentional switching from Send to Search mode with lateral pressure, or possibly even turning the device off completely. This defect can pose a potential safety risk to users and requires rectification.
Upon identifying this issue, we conducted a 100% inspection of our stock, confirming that only
Barryvox 2 and Barryvox S2 models may be impacted. The Barryvox and Barryvox S models from previous seasons are not affected by this issue.
Fortunately, we were able to identify the root cause of the potential malfunction and immediately started the mitigation process, to ensure the timely inspection or replacement of affected devices.
Please return your Barryvox 2 or Barryvox S2 for inspection and replacement.
We have a solution in place for all impacted devices. We, therefore, ask you to:
- Check if you own a Mammut Barryvox 2 or Barryvox S2. Please refer to the pictures and style numbers provided for identification of the correct models.
- Go to our return form:
- Fill in your customer details
- Select “Avalanche Equipment” as item category
- Fill in all details for your device (see list below)
- Mention “Barryvox Recall 2024” as issue description
- Leave empty “Proof of issue”
- Submit form online
- Once your request has been processed you will receive a return label via email to print out.
- Pack your Barryvox 2 or S2 and send it to Mammut for inspection (address on return label) by following the instructions provided by Customer Service. If you purchased a package with shovel and probe, you’ll only need to return the Barryvox device.
- We will check the products and return or send replacements within 7 business days* after receiving your product. Alternatively, you can drop off your Barryvox 2 or S2 at your nearest Mammut store**.
- The rectification of the defect is free of charge.
This process applies no matter where you bought your Barryvox 2 or S2 device.
