Hyper Active Real Time Technology / H.A.R.T. Control Technology
First of its kind in the prosthetics space, the patented H.A.R.T Control Technology provides continuous valve adjustments without preset positions. This means the valve diameter (hydraulic resistance) the user requires at that time can be whatever they need it to be (from fully open to fully closed, and anywhere in between).
“ I spend a lot of time on the golf course and traveling with my wife. Quattro allows me to do all that with greater ease, comfort, and confidence. The Golf Mode helps my golf game substantially. It allows me to be able to put it into a preset fixed position and when I shift my weight I don’t worry about losing my balance. From walking up and down slopes to getting in and out of a car, the transitions are seamless."
