K2 Avalanche Aluminum Probe 300: Shorter or flexible probes are adequate for collecting snow-pit data and identifying crevasses, and we hope that's the only time you ever need your probe. But when it's time to locate a buried avalanche victim, saving a few grams on a shorter, more flexible or fragile model could be a fatal mistake. So even though our probes are as light as anything you'll find on the market, we're most proud of the fact that they're among the strongest and stiffest available BACKSLIDE AUTO LOCK: Utilizes Trigger Pull Handle and non-slip textured shaft for ease of assembly with gloved hands. BACKSLIDE TECHNOLOGY: Delivers 300cm probe with packed volume of a 260cm model. RULER: 1cm markings for precise recording of snow pit data LENGTH: Extended 300cm / Packed size: 42cm WEIGHT: Aluminum 350g
