The Ortovox Avalanche Transceiver is an essential item when venturing into the back country. Not only can it save YOUR life if you get buried in the snow, but it can save other peoples lives by helping to find them. The Ortovox 3+ is one of the best ones on the market. The patented SMART-ANTENNA-TECHNOLOGY ™ with intelligent position recognition automatically switches to the best transmission antenna, meaning you get almost double the range in the worst coupling area. The real time display is easy to read and will tell you the direction, distance and number of victims. It has intuitive search acoustics and visual support at fine search.
