Mammut Barryvox Avalanche Transceiver Package: A digital three-antenna device reduced to the essential functions. The BarryvoxA(R) scores well on simple navigation and clear instructions. With a large receiving bandwidth and an effective search strip width of 70 meters, it offers users a simple interface and intuitive operation. From an easy-to-read display to buttons that can be operated even wearing gloves, shock-proof and break-proof housing and a revolutionarily simple visual interface, the BarryvoxA(R) shows that powerful performance and sophisticated search guidance do not need to be complicated. Design: ergonomic, impact-proof and break-proof. Can be operated while wearing gloves Display: display with background lighting, very easy to read even when wearing polarized glasses Visual interface: shows distance, direction and number of buried subjects Acoustic search guidance: allows the rescuer to visually search the avalanche field Group test with clear instructions Multiple buried subjects: digital signal processing in the event of several buried subjects Effective digital search strip width: 70 meters Digital receiving bandwidth: 70 meters Circular receiving field: almost identical receiving bandwidth for X and Y antennas Reverse direction function to avoid 180-degree search errors Automatic switching from send to search (Auto Revert): if a rescuer does not move for 4 minutes, we assume a secondary avalanche and the device switches to SEND mode (motion-sensor controlled) Attachment: includes highly functional Barryvox carrying system Alkaline battery life: around 300 hours SEND, followed by 1 hour SEARCH* Device tests: automatic self-test, frequency check and function test W-Link: Additional communication channel for improved search performance updatable software Manage the device fleet via W-Link Operating temperature: -25Adeg to +45Adeg Celsius (-13Adeg to +113Adeg Fahrenheit) Battery type Alkaline 3 x AAA 1.5 volt Batteries included Yes Sending frequency 457 kHz Digital search strip width 70 m EN standards EN 300718 Comes with: The PROBE 240 lightweight avalanche probe is safe and easy to use, even when wearing gloves, while the small and compact ALUGATOR RIDE avalanche shovel
