ABSTRACT:
Search device for locating a transmitter, in particular an avalanche-victim search device (1), such that for scanning a search area the search device (1) is swiveled by a user through a range of search angles that covers the region to be searched, which independently determines the position of an avalanche victim or several such victims in a reliable and economical manner, with a magnetic-field sensor that sends to a signal-processing means sensor signals related to the earth's magnetic field that are then sent on as processed signals to the output unit, and to every search direction there is assigned a fixed search angle relative to the earth's magnetic field, so that at every time it is possible to associate the signal received from a transmitter with a fixed search angle.
