evo.com | Mammut Avalanche Beacons > A complete re-design of the industry-leading Pulse and Element beacons brings us the new Mammut Barryvox Avalanche Beacon with improved performance, simpler operation, and better impact resistance. Revamping on a great product is never easy, but Mammut's had the Swiss gnomes working overtime on the new Barryvox. With an enhanced, 70 meter recommended search strip (previously 50 meters), clearer visual interface, and better one-handed operation even with gloves on, the Barryvox sets a new standard in avalanche safety tools. BarryMount Carrying System Adjustable and can be opened or closed with one hand. Beacons Require Training Wearing an avalanche beacon is no guarantee of safety in avalanche terrain. We recommend that backcountry travelers take an AIARE Level One class or the equivalent, and practice the skills they learn there regularly with their partners. Acoustical Search Guidance A sequence of tones guides you in the direction of the buried subject and ensures that you can keep your eyes on the avalanche field during the search. 3 AAA Alkaline Batteries Only SEND battery life ~300 hrs; SEARCH ~ 1 hr Improved Display Backlit display remains clear even when wearing polarized glasses. | Mammut Barryvox Avalanche Beacon 2026 in Gray
