A complete re-design of the industry-leading Pulse and Element beacons brings us the new Mammut Barryvox S Avalanche Beacon with improved performance, simpler operation, and better impact resistance. Improving on a great product is never easy, but Mammut s had the Swiss gnomes working overtime on the new Barryvox. With an improved, 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. The Barryvox S offers several useful features beyond those offered in the standard Barryvox, including: A Smart Search function that interacts with the searcher's actions while in use, simplifying the search, the ability to "unmark" marked victims, "Vital Data" transmission via W-Link, and the ability to use Lithium batteries as well as Alkaline.
