Maximum robustness for accurate probing. The PROBE STEEL 320+ is our longest steel avalanche probe. Designed for accurate probing and very deep snow, it is a reliable tool for professional use. Its reach can be further extended, if required, with an additional 40 cm extension piece. The rigid steel, a 12 mm bore diameter, and the voluminous probe tip guarantee maximum probing accuracy, even in hard snow. The robust steel cable system ensures consistently reliable tension, while replaceable components extend the probe’s service life. UIAA certified for maximum reliability. RRP SPECS Material: Steel segments (12 mm diameter) Fully extended length: 320 cm (with extension option) Collapsed/package length: ~40 cm Weight: ~675 g Assembly system: PFA Quick-Assembly 2.0 (steel cable tension, quick-release strap) Visual depth guide: Clear 1 m mark, neon-orange bottom segment Tip: Large diameter interchangeable probe tip Grip: Rubberized handle for ice-free handling Compatible for extension: Yes, via add-on segment BUYER'S GUIDE Material - The stronger (and heavier!) the material, the more effective it will be at probing. The lighter the probe, the more expensive it gets. Carbon is the lightest (and most expensive), Aluminum is stronger and cheaper, but heavier, Steel is heavy and expensive, but the best at the job. Length - You'll see probes ranging from 200cm-320cm. We don't sell anything less than 240. Successful extractions have been done up to 3m. Keep in mind you'll need to hold on to the probe as you enter the snow. Longer probes mean more ferrules, so count on them being a bit heavier (but not much) and having more mass. Assembly - How quick can you get it together and secured (like really secured!) into place? Practice will help, but make sure it's got an easy lock.
