Avalanche Transceiver and Beacon

ARVA or DVA: safety in the mountains

ARVA and DVA refer to the same device: a transceiver that helps locate a buried person. In practical terms, you ski in transmit mode; in the event of an accident, your companions switch to search mode to guide the probe and shovel. This is the core of the safety trio.

Mandatory? Not legally, but essential for your skiing activities as soon as you leave the marked trails—even for "amateur" skiing. An avalanche transceiver is no substitute for preparation or training; it complements your judgment and equipment (shovel, probe, sometimes airbag backpack). Choose a model with three antennas that is easy to read and has a range appropriate for your terrain; practice using it, and set off with peace of mind.

Which avalanche transceiver should you choose for the mountains?

Focus on the essentials. When choosing your avalanche transceiver, concentrate on these criteria that really make a difference:

• 3 antennas / 457 kHz: current standard, maximum accuracy and compatibility.
• Range & bandwidth: the wider, the faster the initial search.
• Ergonomics: easy-to-read screen, large buttons that can be used with gloves, clear selector (OFF/SEND/SEARCH).
• Ease of use: intuitive interface, responsive direction + distance guidance.
• Multiple victims: marking/deleting to manage a complex scene.
• Group check: quick test of group devices at the start.
• Anti-interference: filters and alerts near electronic devices.
• Auto-revert: automatic return to transmission after inactivity (secondary safety feature).
• Power supply: alkaline batteries recommended, reliable battery life in extreme cold.
• Updates: port or Bluetooth for firmware updates and training via app.
• Holster: secure chest mount, stable when moving.
• Pro options (if needed): extended analog mode, fine adjustments.

Tip: choose a model that you are really familiar with. A simple, well-trained avalanche transceiver is better than a device packed with options you don't use.

How an avalanche transceiver works

An avalanche transceiver continuously emits a standardized radio signal (457 kHz) and is carried in a holster on the chest. For avalanche safety, team members switch their devices to search mode: the screen and beeps guide them to the victim in terms of distance and direction.

Good habits before each outing: group test, check the selector switch (OFF/SEND/SEARCH) and make sure the alkaline batteries are charged. Slip a spare set into your bag. Dedicated training remains the best investment for mastering your avalanche transceiver.

The search procedure: 3 phases

Field training is better than a long guide, but remember the essentials:

• 1. Search for the signal: scan the area in strips (spacing adapted to the search width of the avalanche transceiver) until you get the first hit.
• 2. Approach: follow the arrow and distance, slow down below 10 m, eliminate large unwanted movements.
• 3. Fine search: device flush with the snow, precision cross to find the minimum. Mark, then proceed with probing (perpendicular, quick lock) and V-shaped shoveling from downstream.

Practice regularly (group check, multiple victims, self-revert). A transceiver that is used often saves precious minutes on the day.

Complete safety pack (avalanche transceiver + shovel + probe)

Save time and consistency with a pack that includes an avalanche transceiver, shovel, and probe. One purchase, compatible tools, controlled weight. To get started, go for a simple-to-read 3-antenna avalanche transceiver + 240 cm probe + telescopic aluminum shovel. For regular use, aim for increased range, multi-victim marking, and a 280–300 cm probe. ARVA/avalanche transceiver packs are designed to fit easily into your bag (dedicated pockets), ready for use and training.
