The Avalanche Transceivers

What is a Avalanche Transceivers

The Avalanche Victim Detection Device is an electromagnetic transmitter and receiver operating on the standard frequency of 457kHz. A dva has two functions: transmission and reception.

When off-roading, the Avalanche Transceivers must be in the transmitter position permanently on (after checking the correct operation of the device)

In the event of an avalanche, the witnesses present switch their dva to reception mode to locate the victims.

In choosing his Avalanche Transceivers will take into account:

The signal range and bandwidth:

The more important these are, the earlier the victim's location will be.

Digital and analog modes.

Until 1998, manufacturers used analogue technology. In this case, the signal from the transmitting Avalanche Transceivers is converted by the receiver into sound waves. When a Avalanche Transceivers in reception receives a Avalanche Transceivers in transmission, it emits a "beep", all the louder because the two devices are close to each other or because they are correctly oriented relative to each other. A potentiometer makes it possible to vary the sound intensity of the signal, by adjusting the sensitivity of the receiver. All Avalanche Transceivers manufactured before 1998 are analog.

In 1998, a second generation of Avalanche Transceivers appeared, using digital technology, exclusively or in combination with analogue technology. This is called digital Avalanche Transceivers. The transmitter signal is analyzed by a microprocessor which converts it into two types of visual indications:

an indication of progress (numerical value appearing on a screen);
- a direction indication (diode or arrow that lights up when the receiving Avalanche Transceivers is correctly oriented with respect to the transmitting device).

The number of antennas:

Avalanche Transceivers are composed of 1 to 3 antennas. The recent models all have 3 antennas that simplify the search for victims by giving indications of distance and direction. They are also much more accurate in the final research.

Other functions:

Analysis and separation of signals in the event of burial, multiple victim marking, rescuer protection function with automatic activation of the transmit mode without movement for a certain time (over avalanche)

Simple rules for using Avalanche Transceivers

To be effective with a dva you must know how to use it in search mode. It is not necessary to wait until the accident to learn because with stress and confusion, research must be like a reflex. Practice searching with dva before the accident.

Do not wear your dva just under your jacket: as soon as it gets warmer, when you take off your jacket, the dva appears in the open air: in case of an avalanche it may be torn off!

Don't leave without a snow shovel or probe: you have just found a buried person in less than 5 minutes but it takes you 45 minutes to clear them by hand.... the time to die asphyxiated under the snow.
