Individual Mechanical Advantage System IMAS - North American Rescue 90-5005  

The Individual Mechanical Advantage System is an ultra-compact lightweight - Grab & Go “piggy-back” Mechanical Advantage System. Engineered to accomplish full spectrum operational requirements for full-spectrum users from urban through mountain with the highest possible efficiency and safety margin. Often referred to as a riggers’ “get out of jail free card” due to its innate ability to solve and fix complex vertical rescue problems. The iMAS size, ease of use, and capabilities makes it an easy decision to be included in the load-out for any vertical mission set while easily carried or packed / attached onto an aid bag, mountain pack, cargo pocket, harness gear loop, or fast-rope bag. Its use is simple enough for the vertical novice, but its capabilities expand with the level of expertise of the rescuer and the complexity of the rescue.
