Barryvox S2

The Recall has been addressed and replacements have been issued. These units have been tested & verified by Mammut.

The compact avalanche transceiver is essential in avalanche-prone terrain, with intuitive operation & 70m range, it guides & supports your search for buried subjects - even in complex rescues. To keep you safe on tour, the Barryvox S2 continuously checks its own operation with a self test function. For added safety on rescues, the avalanche transceiver is equipped with a rescue SEND function & automatic switching from search to send. While searching for buried subjects, it guides you quickly with clear instructions via audible search guidance and cues on the easy-to-read animated display. With fine search, it offers reliable guidance down to the last meters. You can perform updates, configurations & avalanche training on the Mammut app, so you're ready to make fast, smart decisions in emergencies

• Intelligent fine search guidance: patented technology that guides you through the fine search with fully interactive visual and acoustic guidance.
• Probe indication: as soon as the minimum burial depth has been found, the probe display guides you visually and audibly from the fine search to pinpointing.
• MIP display: the high-contrast and innovative Memory-in-Pixel display is clear and easy to read even in bright sunlight.
• Voice guidance: your Barryvox® assists you with additional instructions in all search phases. This feature is currently not available in Germany, Austria and Switzerland and the US.
• Rescue SEND: Protective function for non-searching rescuers. In the event of a secondary avalanche it automatically switches to SEND to allow the rescuer to be located
• Auto-revert to SEND: safety function for rescuers searching with an avalanche transceiver in the event of a secondary avalanche burial. If a rescuer does not move for four minutes, the avalanche transceiver automatically switches from SEARCH to SEND thanks to a motion sensor.
• Automatic self test: your Barryvox® checks your transmit and search function signal when it is switched on and carries out regular transmission and battery tests.
• Interference Guard: your Barryvox® manages and reduces signal interference and indicates any interference in transmit and search mode.
• Group check: check the transmission frequency and strength of other avalanche transceivers quickly and easily with this function to ensure correct functionality.
• Acoustic 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.
• Intuitive visual interface: guides you intuitively through all search phases and provides an overview of multiple burials.
• Auto-Select: in the event of multiple burials, your Barryvox® will guide you to the strongest signal first.
• Marking function for multiple burials
• Reverse direction function avoids 180-degree search errors
• Deep burial mode: if a very deep burial is detected, the fine search automatically starts earlier (> 3m) for precise guidance.
• Compatible with the Barryvox app for firmware updates, configuration settings, search training with the Barryvox®
• Barryvox carrying system (included in delivery): safe and comfortable wearing of the avalanche transceiver on the upper body.
• Additional functions for advanced users: discover all the possibilities of the Barryvox® S2 with the alternative search mode and individually configurable settings, which let you retain flexibility and control in every search scenario.
• Analog search technology: the extended analog function for more efficient and accurate searches helps to solve complex search scenarios thanks to complex algorithms and signal processing techniques.
• Pro Check: in this mode the transmit frequency, the pulse duration and the period lengths of other avalanche transceivers are checked.
• Pro search settings: combines a digital direction and distance display with an analog tone in the standard search mode and allows access to the alternative search mode.
• Configurable settings for acoustic guidance, voice guidance, visual guidance, Pro Test, vital data detection and time-out definition for rescue send and automatic switching from search to send.
• Scrolling function for multiple burials: gives a clear overview of up to 16 buried subjects for more efficient group searches and triage decisions.
• Selection function for multiple burials: in the case of multiple burials, burials can be selected, marked and unmarked on a list.
• Marking for deep burials up to a distance of 6m
• Additional Bluetooth channel: enables faster separation of signals in complicated rescue scenarios.
• BT vital data detection: the vital data transmitted via Bluetooth helps rescuers to make triage decisions in order to focus on buried subjects with an increased chance of survival.
