Abstract: The invention uses four antennae in order to pinpoint the exact position of the transmitter, especially at a close distance. The four antennae form two pairs of antennae placed at a specific angle to each other. The pairs of antennae are respectively comprised of two antennae that are also placed at a specific angle to each other. The pairs of antennae are respectively comprised of two antennae that are also placed at a specific angle to each other. The direction of the field line of the send antenna can be detected by comparing the signal intensities of the antenna pairs. Lateral deviations and forward or rear deviations from the shortest distance point can be recognised by comparing the signal intensities of the corresponding antennae. All signals have the same intensity at this point. Search devices are mainly used by wilderness skiers and those choosing to ski off piete.
