DVA Packs - 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.

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.

The technology at the heart of an 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 pinpoint the precise location of victims. The latest models incorporate advanced features such as multiple victim management, direction indication and approximate distance.

DVA selection criteria

a. Range and accuracy

Range is crucial to your choice; it can generally vary between 20 and 70 meters. A wider range offers a better chance of quickly locating victims buried under snow. Accuracy also depends on the device's ability to point effectively towards the snow, while reducing interference.

b. Ease of use

For athletes practicing in extreme conditions, it's vital that your equipment is easy to use. Choose a model with an intuitive interface and simple controls, accessible even with thick gloves! Devices with backlit displays are particularly recommended for use in difficult lighting conditions.

c. Additional functions

Some advanced features can make all the difference:

• Multi-victim mode: often allows users to manage several signals simultaneously, while sometimes having the option of marking a found victim to continue searching on others.
• Self-test: checks that all components are working properly.
• Interference protection: minimizes impact of other electronic devices on search accuracy.

Recommended practices and training

Buying a high-performance avalanche transceiver is only the first essential step; it must be complemented by proper training in its use! Specialized training courses will teach you not only how to use your device effectively, but also how to understand dynamic snow and avalanche terrain.
The purchase of an avalanche beacon is a serious decision requiring careful consideration of the technical features appropriate to your level of mountain activity.
We therefore recommend that you choose a robust, reliable device equipped with the latest technological innovations to guarantee the safety of your fellow adventurers! Don't forget that being alone shouldn't encourage reckless risk-taking!
