Abstract: A probe, particularly for locating trapped victims in avalanches, includes a receiver tuned to the transmitting frequency of transmitting units and with at least one antenna. The receiver is provided with a circuit for level evaluation of the received signals whereby the circuit indicates any surpassing of the signal level while approaching the vicinity of the transmitting unit to make probing easier for the rescuer, to reduce the time needed for this purpose, and to offer significant assistance in the interpretation of different objects detected by means of the probe.

Abstract: A locating device, particularly for locating trapped victims under avalanches, under debris or under collapsed buildings, equipped with a receiving unit (6-13) for signals from transmitters and preferably a transmitter (13, 14), as well as optical (6) and/or acoustic (12) display units, whereby the receiving unit is connected to three preferably orthogonally arranged ferrite rod antennas (2, 3, 4). All antennas (2, 3, 4) are disposed in a compact housing (1) together with the receiving unit (6-13) and preferably also the transmitter (13, 14) to ensure accurate locating of the trapped victim across the largest range possible at compact design whereby one antenna (4) is of substantially shorter length than the two other antennas (2, 3). The receiving unit is provided with a DSP module (11) for incoming signals of the antennas (2, 3, 4).
