    Abstract: For this study a field test was carried out to determine the total time needed by independently working test persons to locate two active transmitters, placed 15m apart in a 50x50m area of simulated avalanche debris. A main point is to evaluate the effectiveness of electronic probes with an acoustic hit indication and/or a “deactivating function” for the transmitter. The interpretation of the results indicates that compared to other combinations, modern equipment (triple antenna beacons with marking function) brings significant benefits to resolving a double burial situation. Experts profit more from modern combinations than beginners. This clearly shows that special training and personal knowledge of all aspects of companion rescue are imperative in a slide scenario. Using specific searching techniques (Three Circle Method) did not prove significantly beneficial. However it is noted that only very few of the test persons know such techniques and are able to perform them correctly under stress. The use of an electronic probe is shown to be a big advantage, both with acoustic support only as well as with acoustic hit indication and a deactivating function. The latter brought the greatest improvement in overall search time. This result can in certain ways be seen as an assignment for manufacturers to develop fully compatible equipment.
