The Guide Probe is one of the easiest and fastest to assemble avalanche probes in a professional length of 320cm. Speed cones attached to the end of each probe section speed up assembly. It assembles in seconds by pulling the lead inner tube attached to a coated stainless steel cable. It locks into place with a simple, strong pop-button. The probe includes 5cm increment laser etched depth markings for accurate snow depth checks. The stainless steel cable has an adjustment knob to adjust cable tension if the probe is loose when assembled. Includes nylon storage bag. The storage bag has strap loops to strap the probe to any shovel handle.
