W-Link: Additional communication channel for improved search performance 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) Visual interface: shows distance, direction and number of buried subjects Group test with clear instructions Design: ergonomic, impact-proof and break-proof. Can be operated while wearing gloves Circular receiving field: almost identical receiving range for X and Y antennas Operating temperature: -25° to +45° Celsius (-13° to +113° Fahrenheit) Manage the device fleet via W-Link Display: display with background lighting, very easy to read even when wearing polarized glasses Digital receiving range: 70 meters Device tests: automatic self-test and function test Reverse direction function to avoid 180-degree search errors Acoustic search guidance: allows the rescuer to visually search the avalanche field Multiple buried subjects: digital signal processing in the event of several buried subjects Attachment: includes highly functional Barryvox carrying system Effective digital search strip width: 70 meters updatable software
