It is a transceiver worn under the clothes by all the practitioners of the snowy mountain (off-piste skiers, hikers, snowshoers, glaciers …)
Use, instructions for use
To be effective with an ARVA you have to know how to use it in search mode. Do not wait for the accident to learn because, with the tress and confusion, research must be like a reflex.
Practice and train yourself again with ARVA before the accident.
In the event of an accident, the ARVA of each user must be able to “interact” with the device of the other persons present (those in remission and those in reception, of whatever mark they are). For this reason, all ARVAs today marketed in Europe transmit (and receive) on the same radio frequency: 457 kHz. It is an international standard.
Note, however, that in recent history other types of devices have been marketed
– the 2.275 kHz single-frequency devices (Pieps 1 type) are obsolete and should no longer be used
– The 2,275 and 457 kHz dual-frequency devices (ARVA type). 4000, Orthodox F2) are endangered
When traveling to distant countries, it may be wise to learn about the type of equipment used on site. Do not hesitate to rent equipment on-site if the frequency used is not the same as your devices.
Errors to avoid
– wear are ARVA just under his jacket: as soon as it is warmer, removing his jacket the ARVA appears in the open air: in case of an avalanche it may be torn off!
– leave without a snow shovel or probe: you have just found a person buried in less than 5 minutes, but you need 45 to release it by hand … the time to die asphyxiated under the snow
– to leave with batteries very worn (or without batteries at the beginning of the season)
– Do not practice using the device: in case of an avalanche, stress does not help, you must have reflexes that saves. For this, train regularly!
– leave the ARVA at the bottom of the bag: even lit, it only serves to find the bag if the force of the avalanche tears it.
It is necessary
– know how to give up a race, the ARVA is not an avalanche “shield,” nor a guarantee of survival …
– Check the good working order and the start of all the devices starting each hike. This avoids devices in breakdowns or stunned hikers who would not have connected.
– When traveling to another continent, check that the frequency of use of the premises corresponds to that used in Europe is 457 kHz
The ARVA is the only detection device adapted to the practice of ski-mountaineering or ski touring (or snowshoeing) because of the speed of its implementation in case of an avalanche, from the moment or all participants are equipped.
Use: skiing, snowshoeing, surfing, waterfall, winter mountaineering (and summer if necessary)
Weight: approx. 300 grams with batteries

Note: the probe is part of the trilogy ARVA + shovel + indispensable probe for the effective search of an avalanche victim.
