1. DVA
Evo BT
DVA (Avalanche Victim Detector) -
The Evo BT is a high-end avalanche transceiver (DVA - Détecteur de Victimes d’Avalanche) from the brand Arva that combines performance and connectivity to meet the needs of the new generation of users.
Equipped with a search band width of 60 m and Bluetooth technology, you can connect it to the ARVA® app to access a range of services: configure the transceiver, prepare your outing, or even train for rescues. Furthermore, during your search it will automatically switch back to transmit mode in the event of a secondary avalanche. You can also easily ensure that everyone in the group has activated their transceiver thanks to the Group Check function: simply place the device in proximity search mode.
Finally, in multiple-victim situations, this device features a marking function for up to 4 victims and 3 antennas to improve search accuracy. It is also equipped with a flexible holster that adapts to all body shapes.
As you can see, the Evo BT, with its multiple features, is perfectly suited to ensure your safety during your outings in snowy terrain.

| SEARCH STRIP WIDTH | The search strip width corresponds to the area scanned by the search device. The larger the search strip width, the greater the area covered by the device. This can be used to compare the performance of different beacons. |
| AUTOMATIC RETURN TO TRANSMIT | During a search, in the event of a secondary avalanche, the return to transmit function automatically switches the device back to transmit mode without user intervention. The return to transmit occurs either by timer, i.e., after a delay without user action, or by motion detector, after a delay without device movement. These delays can be configured in the device's settings menu. |
| DYNAMIC INTERFERENCE MANAGEMENT | Interference management optimises the device’s performance when searching in an environment “polluted” by electromagnetic interference. To do this, the device in search mode automatically reduces the search strip width to focus on the signal of the sought device, ignoring parasitic frequencies. This function can be disabled by the user. |
| GROUP CHECK | The Group Check function allows you to simply ensure that all members of a group are wearing a beacon in transmit mode. The group check function places the device in close proximity search mode, allowing each group member to be individually checked by standing within one metre of them. |
| MARKING FUNCTION | During a search, once a victim is located, the marking function allows you to disregard that victim to focus on searching for another. The signal from the “marked” victim is no longer taken into account for the remainder of the search. |
| AUTOTEST | When switched on, the device performs an automatic check. It monitors battery level, proper device functionality, and informs you if there is a problem. |
