If you bought one of Mammut’s brand-new avalanche transmitters last month — the brand has some bad news.
After discovering a potentially dangerous malfunction, the Swiss brand recalled all units of two models released in October 2024. According to a voluntary recall announced on the brand’s website last week, the Mammut Barryvox 2 and Barryvox S2 avalanche transmitters may have misaligned switch buttons.
As a result, some of the devices can inadvertently switch from Send mode to Search mode — or even shut down completely. That could make it difficult or impossible for an avalanche victim’s beacon to send the signal required to execute a search. The Send mode is what buried skiers or hikers would use, while their teammates would use Search mode to try and locate them.
Mammut said the malfunction, which may be present on units of both devices, came from an inaccurate assembly step. So, the Swiss company requests that all owners send in their transmitters for inspection and possible replacement — free of charge. Since these transmitters are meant to be “life-saving devices,” Mammut is taking the problem “super-seriously,” a spokesperson said.
“We sincerely apologize for the inconvenience this recall may cause,” Mammut said in a statement. “We know that many of you are already busy organizing your first trips to the snow. We promise to be quick and return the device once checked or send a replacement device for your beloved transmitter. The Barryvox 2 and Barryvox S2 are and will continue to be the best avalanche transmitters on the market, and for us at Mammut it is a top priority to safeguard the trust of our customers.”
Barryvox 2, Barryvox S2: Recall Instructions
After realizing there was a problem with the transmitters, Mammut inspected 100% of its inventory to confirm that only the Barryvox 2 and Barryvox S2 models may be affected, a press release stated. Sales of both devices have now been temporarily removed from the website and pulled from the shelves of brick-and-mortar retailers.
Previous seasons of transmitters, like the Barryvox and Barryvox S, don’t have the malfunction issue. A representative for Mammut could not provide specifics for how many units are likely affected.
“We are currently assessing the number involved in the voluntary recall of the Barryvox S2,” a Mammut spokesperson told GearJunkie. “While specific figures are still being finalized, our priority remains transparent communication and customer safety.”
