STEALTH 270 avalanche probe - BCA's mainstream probe for recreationists. Collapsed length fits in most packs. — EVERY SECOND COUNTS - BCA’s updated probes feature dual-sized depth markings that are easy to see when you’re performing a rescue or logging a snow profile. Pro-level aluminum models are laser-etched to prevent wear. Our Stealth Quick-Lock hardware creates a smaller bundle when folded up and eliminates loose cables that can whip you in the face when you’re furiously probing.
