Smart Antenna Technology - analyzes the positions of the antennas in the avalanche and automatically awitches to the best transmission antenna * Secondary avalanche switchover: 120 sec. - If the transmitter registers no movement for more than 120 seconds while searching, it automatically switches back to transmission mode. Rescuers are thereby protected from follow-up avalanches at all times. * Recco Reflector inside * Fast Find - real-time display is limited to the essentials. It displays the distance and direction. Once you are in the refined search area, the displayed circle shows whether you are getting closer to the victim or moving away from him/her. Battery status and number of buried/marked victims appear small. * Fine Search - the patented circular display shows you whether you are getting closer to the victim or moving away from him/her in increments of 10 cm. The optimized, distinct search acoustics supports you in the search by pitch of the tone and volume.
