The Avalanche Training Center ATC is a stationary facility for practising avalanche victim search with avalanche transceivers and avalanche probes. The transmitters, which are buried in the search field, send the same signals as an avalanche transceiver. At the control centre, the remotely controlled transmitters can be activated randomly (practice mode) or manually (expert mode). With these options, simple and complex avalanche victim scenarios, especially multiple victim cases, can be trained.
