Intelligent fine search guidance – Patented technology with complete interactive visual and acoustic guidance through the fine search.
Acoustic search guidance – A tone guides you in the direction of the buried subject and allows you to concentrate visually on the avalanche field during the search.
Voice guidance – Delivers complementary guidance and support during all search phases.
Analog Search Technology – The extended analog feature allows for a more efficient and accurate search and help in resolving demanding search scenarios with advanced algorithms and signal processing techniques.
Probe Indication – When the minimum burial depth is found, probe indication guides you visually and acoustically from fine search to pinpointing.
High-contrast, cutting-edge MIP (Memory in Pixel) display provides exceptional clarity and readability in harsh sunlight.
Extended Advanced Features - Discover the possibilities of the Barryvox® S2 with the alternative search mode and individually configurable settings, giving you freedom and control in any search scenario.
Compatible with Mammut app for firmware updates, configuration settings, Barryvox® search training, extended user manual, and knowledge base.
Intuitive visual interface provides detailed guidance through all search phases and an overview of multiple burial situations.
Self-Test function checks that the device is transmitting and searching correctly on startup and provides ongoing send and battery test.
Group Check function quickly and easily checks the transmission frequency and level of devices to ensure optimal functionality.
Interference Guard intelligently manages and mitigates signal interference and indicates if intererences are detected in both send and search mode.
Auto-Select function guides you to the strongest/closest signal first in case of a multiple burial situation
Buried subjects can be selected from a list, marked (MARK) and unmarked (UNMARK)
Deep Burial Mode – if a deep burial is detected, fine search is automatically started earlier (> 3m) and provides precise guidance.
Auto guidance: device continues to guide the rescuer to the buried subject in the event of signal failures or overlaps
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 – Automatic switch from search to send if a rescuer does not move for four minutes thanks to advanced motion sensor.
Reverse direction function prevents 180-degree search errors
Includes Barryvox® carrying system with SafeLock which prevents accidental activation of search mode
Compatible with lithium batteries (for battery life of 300 hours in SEND)
Updatable software
Pro Check – Verifies the transmit frequency, the pulse duration as well as the period lengths of the tested device.
The analog tone allows you to identify signal-overlap or other difficulties encountered during multiple-burial searches and helps in resolving demanding search scenarios. Automatic or manual mode possible.
Pro-Search Setting – The combination of a digital direction and distance indicator with an analog tone in standard search mode, and allows access to the Alternative Search Mode.
Clear overview and scrolling function in multiple burial scenarios: Gain an overview of multiple burial situations (up tp 16) for more efficient group searches and triage decisions.
Unmark function for multiple burials
Deep burial marking up to a distance of 6m
Vital data – Information about vital data and burial time is displayed in SEND mode for first responders.
Additional bluetooth channel supports in a faster separation of signals during complicated burial situations.
Individually configurable settings for audio guidance, visual guidance, Pro Check, vital data detection and time-out definition for rescue send and auto-revert to send
Fleet Management via Bluetooth
