Activities such as but not limited to mountaineering, rock and ice climbing, caving and technical rescue are potentially hazardous by their very nature. Any person using CMI equipment in any manner is personally responsible for learning the proper techniques through personal instruction by an instructor competent in all safety techniques and backup systems. The CMI catalog is not a substitute for proper instruction. CMI cannot be responsible in any way for misuse of any equipment described on this website or in our catalogs or flyers.
