Whether you go with the 240 centimeter or 300 centimeter option, this probe is ideal for long, strenuous days in the backcountry where weight really does matter. The Carbon Speed Tech probe is built with triaxially-woven carbon fiber for incredible strength and weight savings, with the 240 centimeter version coming in at 220 grams and the 300 centimeter at 284 grams. Bright five millimeter increment markings and a quick-draw deployment system, like that of the pull-start on a lawnmower, help shave time during a rescue, too.
