The Enforcer is a giant breakthrough in rope rescue. This little beauty fits in the palm of your hand, but has all the capability of a full sized dynamometer, and then some. Samples in lbs, kg, or kN, slow samples, fast samples (500x per sec) and can accurately measure forces to 4 kN (slow) and 20kN (fast). It has built in temperature compensation. It has built in swivels on each end, and can be used during a rescue to gauge forces. It is also blue tooth capable, and can transmit data to your smart phone!
