We have used radar guns for years to prove how improved mechanics can improve velocity or develop more effective change ups. Without proof, players simply go back to what they are comfortable with… and as coaches, we just watch pitchers undo what’s good for them.
Dave Marinelli is one smart engineer who developed this revolutionary Rev Fire Spin and speed detector.
It quite simply shows in real time, how many revolutions per second your pitchers will throw and give any coach a more willing student…one who should easily buy into new ideas as they see the immediate results and improvement.
It is astounding how many Olympic teams, colleges and training facilities rave about this one of a kind fastpitch training product. It’s no gimic… That, I will guarantee!
