Abstract: An improved battery-powered device and system for avalanche transceiver rescue. The device comprises a transmitter, a receiver, microcontroller firmware system, graphic display, audio speaker and input switches residing in a single portable housing with a flip lid. When the flip lid is closed, the system transmits a radio frequency signal at a predetermined interval. When the flip lid is opened, the system deactivates the transmitter and activates the receiver. The receiver comprises three mutually orthogonal tuned-coil antennas. The system digitally processes the received signal strength and polarity of the signal from one or more of the antennas to guide a user to a transmitting beacon. The antennas are spatially isolated permitting the use of higher-sensitivity antennas. The system digitally controls the sensitivity of each antenna enabling scans for signals based on a specified proximity range to the exclusion of other proximity ranges.
