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.

Abstract: A collapsible snow probe includes a tip and a plurality of elongate tubular members each of which has an interior bore. A cable is provided having a first end and a second end. The first end is secured to the tip. The cable extends through the interior bore of each of the tubular members with the second end protruding. A cable engaging member secured to the cable. A clamping member that clamps onto the cable engaging member and bears against a remote end of the plurality of tubular members when positioned in end to end relation, such that the cable is maintained in tension and the interior bores of the tubular members are maintained in axial alignment.
