The Stealth 240 Probe features Backcountry Access' quickest deployment system to date, because you don't want to be fiddling with a probe when every second counts. BCA's Quick-Lock deployment lets you toss the probe in the air and simultaneously pull a notch to deploy the probe instantaneously, and the deployment tucks inside the first probe section to reduce pack space. Laser-etched depth markings assist with measuring snowpack when you're doing stability tests.
