The TruLight Caver is a small, lightweight, LED light designed specifically for the exacting requirements of cavers (spelunking). There are a number of features that have been included after extensive consultation with local cavers.
The CMI Ultrascender is one of the strongest ascenders made. It is constructed of an extruded and machined body. The cams are made of 4140 chrome-moly steel which gives the cam the same corrosion resistance as stainless steel but increases both tensile and yield strength. The cams are harder than the best knife blades and are backed by CMI with a lifetime wear out guarantee. All springs and operating parts are constructed of stainless steel.
