I have been coaching travel ball for over a decade. I have been using RVP since Don first put it on the market. It is in my opinion one of the best tools for teaching hitting there is. It has made a huge difference with our hitters. It is not magic, it will take time to film all of your players and time to evaluate but it is well worth it. Take the time to really understand all the features and what it enables you to do. I cant tell you how many players upon seeing a clip of their swing have said, "wow I didnt know I was doing that".
