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 * Visual plus Acoustic search - LEDs are used to show the distance to the victim, the direction using arrows and if there is more than one victim. Large LEDs are easy to read especially in poor visibility conditions and at night. The visual search mode is supported by intuitive search acoustics. Higher and fast sounds tell you that you are approaching the avalanche victim. * Just two buttons make operating errors practically impossible. Once switched on, it is possible to switch between transmission and search mode using the safety switchover button
