I began using this with my catchers a few weeks back. It is a great tool for teaching the catcher to work to the ball with "strong hands." The catcher is assisted by this tool from the beginning of receiving all the way up until the ball is received. One can mix inno-glove drills along with drills using a catcher's mitt. The CRT belt is easy to use and is quite easy to include with the catcher's other tools and equipment. It will fit into the catcher's equipment bag without taking up much room at all. It's a tool that is used at the MLB, NCAA and HS level.
