The dry fire pro was some of the best money I’ve spent. I had a shoulder surgery in March of 2017. I didn’t think I was going to make the archery season here in AZ. But I added the dry fire pro to my P.T. and it made a world of difference. Got me ready and in shooting shape for the 2018 January season. I was able to take a beautiful mule deer and javelina. I owe a big part of my success to dry fire pro it is a great tool to stay in shooting shape anywhere and year round. Thanks dry fire pro!
