摘要： Search devices fitted with only one send and receive antenna do not enable buried persons to be found in a quick and reliable manner because the strongest signals can only be detected at extremely short distances when the antennae of the transmitter and reception devices are placed in a parallel position.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 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 intenisties 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 piste.
