  • "Our RevFire is a valuable tool in fall training. We can accurately gauge breaking ball performance and focus attention where needed. The RevFire feedback results in 
    measurable improvement. I would recommend it to any coach."

  • "Without a doubt the best training tool I have ever used in my pitching instructions!  My students work tirelessly to beat their previous best spin rates. This tool is a difference maker."

  • I was one of the first to buy your great product. No serious pitcher or coach should be without the RevFire. One of my pitchers started out with 17 rps spin on her rise, today she has hit 30. We use the RevFire almost everyday and use it even in pre-game. Thanks for helping the sport of softball."

  • "The impact on my pitching students was immediate and substantial.  The most dramatic improvement was the rate at which the pitchers were learning and developing.  It has progressed to a point, where I use the RevFire every day, for every lesson and every pitch. The RevFire system has far exceeded my expectations and would recommend it to coaches, instructors and individual pitchers alike."
