The probe and the DVA (Detector Victim Avalanche) are part of the triptych of the base, with the shovel, the perfect big mountain riders !

Precision Ski will help you to better understand their utility, in order to choose the equipment that you will match the most.

The DVA : essential element from freeride

The DVA, formerly known as the TRANSCEIVER, allows both of you to find your companions were buried under the snow and to be regained if it is you who are caught up in the avalanche. When you leave, all the detectors must be switched on on the mode to "issuer", in order to be able to be found. When a person is swept along by an avalanche, his companions will pass in mode "receiver", to find in less than 15 minutes. After this period, the chances of survival are significantly reduced.

Regardless of the brand of your DVA, they will communicate all between them. This is the number of antennas which will determine its performance, in particular for the search mode. The best-performing models are intended mainly for mountain warned. It is best for hikers and freeriders casual to choose a DVA more simple, so as not to be lost in the midst of different features, and to respond more quickly.

Which sensor snow choose ?

Once you have identified the approximate location of the victim using your avalanche transceiver, the probe, snow will allow you to locate with precision, the skier under the snow.

The probes snow differ in their length, their diameter, their materials and their assembly system and closing. It is up to you to analyse if you prefer the weight, the resistance or the length. When we go up in range, the sensors will be more robust, and more expensive, but will also have a longer life span.
