Ortovox's Smart Antennae Technology determines your body's orientation and switches to the optimal transmission antenna for better transmission range to rescuers. It doesn't matter which beacon is being used for searching, and through a motion sensor the Zoom+ automatically switches back to transmission mode in case searchers are hit by an additional avalanche. Features include intuitive search acoustics, and large LED displays with distance information and directional arrows. Two operating buttons turn the beacon on or off and from search to transmit mode. It operates on just one AA battery.
