DVA - Snow safety

Winter sports in the mountains, such as off-piste skiing, mountaineering and deep-snow hiking, require not only excellent physical and technical preparation, but also adequate safety equipment. The Avalanche Victim Locator (AVL) is one of the most important tools for guaranteeing safety in the mountains. This guide takes a detailed approach to choosing the right avalanche transceiver for your needs, with technical advice for advanced athletes. Find out more about our best avalanche transceivers and other safety equipment.

1. Understanding the role and importance of an avalanche transceiver

An avalanche transceiver is an electronic device designed to quickly locate people buried under snow following an avalanche. Its operating principle is based on the transmission and reception of radio signals. In transmit mode, the avalanche transceiver emits a signal that other devices can detect in search mode. Each member of the group must wear his or her avalanche transceiver in transmit mode when traveling in avalanche terrain.

Technology at the heart of the avalanche transceiver: analog vs. digital

Analog avalanche transceivers, which are older, use a continuous signal and require a certain amount of experience on the part of the user to interpret the sounds emitted by the device. More modern digital avalanche transceivers offer an interface that guides the user through a step-by-step search process, with visual and audible indications to help locate victims accurately. The latest models incorporate advanced features such as multiple victim management, direction indication and approximate distance.

2. Selection criteria for an avalanche transceiver

a. Range and accuracy

Range, which generally varies between 20 and 70 meters, is a crucial factor. A wider range offers a better chance of locating victims quickly. Accuracy also depends on the device's ability to point effectively at the victim while reducing signal interference.

b. Ease of use

For athletes working in extreme conditions, ease of use is paramount. Choose a DVA with an intuitive interface and simple controls, accessible even when wearing gloves. Models with backlit displays are preferable for use in low-light conditions.

c. Additional functions

Some advanced features can make all the difference:

• Multi-victim mode: allows simultaneous management of multiple signals, while marking a found victim to continue searching for others.
• Self-test: checks all device components for proper operation.
• Interference protection: minimizes impact of other electronic devices on search accuracy.

3. Recommended practices and training

The purchase of an avalanche transceiver is essential, but must be complemented by adequate training in its effective use, as well as an understanding of snow and avalanche terrain dynamics.
The purchase of an avalanche transceiver is a serious decision that requires careful consideration of the technical features appropriate to your level of practice and mountain activities.
