Abstract: Electromagnetic interference can complicate avalanche rescue searches by reducing receiving range or causing unstable indications. Potential sources of interference include personal electronic devices, metallic and magnetic objects, electrical or electronic infrastructure, and atmospheric electrical activity. Their effects depend, among other factors, on the specific combination of avalanche transceiver and interfering source, the distance, and the operating mode. This paper considers interference separately for transmit and search mode and combines published studies with qualitative internal observations and practical measurements. The 20 cm recommendation in transmit mode and the 50 cm recommendation in search mode are discussed as important practical guidelines. In particular, practical implementation in search mode shows that this recommendation alone does not guarantee interference-free searching. The paper focuses on a conceptual six-step process. It is intended to support advanced users and professional organizations in considering potential interference during preparation, detecting it during a search, and adapting their procedures to the specific device.
