4 Knobs

Master your swing with 4 K***S. It gives the hitter instant feedback in real time: you will FEEL, HEAR, & SEE what’s going on in your every swing rep. The audible click of the sling hitting the metal stop will let you know when you are at max acceleration; the sling dowel will let you know if you are inside-out and your swing radius is tight, the spring in the handle lets you feel the tension. You will become quicker and freer - you will develop better intermuscular coordination. I’m excited for you to get this in your hands & make it part of your training protocol. You will go from good to great!
