This is the most popular avalanche probe in the entire range of Ortovox probes. The reason is simple: the Ortovox 240 HD pfa is built to last, super easy to use, fully-featured and popularly priced. Constructed from 7000 series aluminum, it is extremely light but very stiff, a very important feature for a probe. A virtually indestructible steel cable keeps the sections together and the patented flash assembly, or pfa, instantly pulls the sections together when seconds matter. The 240 HD pfa also features an insulating anti-slip grip sleeve and centimeter markings down the length of the probe. The Otrovox 240 HD pfa, in conjunction with avalanche rescue knowledge, is a lifesaving combination.
