Transceiver Interference Guidance

Avalanche transceivers are susceptible to interference by electronic devices, metal objects, and magnets if they are too close.

The document below provides practical guidance on how to avoid problems with interference. It was created through a collaboration by Avalanche Canada, the Canadian Avalanche Association, the US National Avalanche Center, Colorado Avalanche Information Center, Utah Avalanche Center, Northwest Avalanche Center, and manufacturers of avalanche transceivers.
