The Avalanche Probe is long enough for professionals and deep snowpack, with the benefit of being lightweight. The Avalanche Probe with Advanced Locking System is an absolute essential for backcountry travel. The Avalanche Probe is 270cm long and collapses down to easily fit in your backpack. Lightweight, so there's no excuse for not carrying this avalanche probe. Depth markings are easy to see when you're performing a rescue or logging a snow profile. The avalanche probe has quick-Lock hardware and creates a small bundle when folded up, and eliminates loose cables that can hang up or even whip you in the face when you're furiously probing.
