When you head into avalanche terrain, every person in the group carries the same three tools: an avalanche transceiver, a probe and a shovel. Together they make a companion rescue possible. Each one only works if everyone has all three and knows how to use them, so they are best thought of as a single system.

The short version

In avalanche terrain, everyone in the group carries a transceiver, a probe and a shovel.
The transceiver leads you to the burial, the probe pinpoints it and the shovel digs it out.
A metal shovel blade cuts through avalanche debris far better than plastic.
An avalanche course and regular practice matter as much as the gear.

Avalanche transceivers (beacons)

A transceiver is worn on your body in send mode all day, transmitting a signal on the international standard frequency of 457 kHz. If someone is buried, the rest of the group switches to search mode and follows the signal to the burial. Modern transceivers are digital with three antennas, which makes the search more intuitive and helps pinpoint the location in the final close range search.

When choosing a beacon, look at how simple the display and controls feel to you, how it handles multiple burials, and its range. A beacon you know well is worth more than any feature. Check your group's beacons at the trailhead every time, and practice searching every season.

Probes

Once the transceiver brings you close, the probe confirms the exact location and depth of the buried person so you know where to dig. Probes fold into sections and snap together with a pull cord. Longer probes reach deeper burials, and aluminum and carbon are the common materials. Many backcountry skiers carry a probe of 240 centimeters or more.

Shovels

Digging is the slowest part of most rescues, so the shovel matters more than people expect. Avalanche debris sets up hard, and a metal blade cuts through it far better than plastic. Look for an aluminum blade, a telescoping shaft for leverage and a grip you can hold well with gloves on. Some shovels convert into a hoe mode for moving snow quickly.

Tool	Job in a rescue	What to look for
Transceiver (beacon)	Leads you to the buried person	Three antennas, simple controls, multiple burial handling
Probe	Confirms location and depth	240 cm or longer, quick assembly
Shovel	Digs them out	Metal blade, telescoping shaft, a grip that works with gloves

Packs and airbags

A ski touring pack with a dedicated avalanche tool pocket keeps the shovel and probe organized and quick to reach. Airbag packs add another layer of protection by helping keep a caught skier closer to the surface. They are a supplement to the beacon, probe and shovel, not a replacement.

Education

Gear is only part of being prepared. An avalanche course teaches terrain choice, snowpack observation and rescue practice, and it is the best investment you can make in the backcountry. Our backcountry safety guide has more on getting started.
