Our personal favorite and top hitting tool with coaches is now available to everyone.
The FBT Flat Trainer wood baseball bat is a great tool for teaching proper swing path.

These specially designed flat bat trainers allow you to approach your work on the tee or live batting practice with immediate and constant feedback. When a proper path to the ball is exhibited, the ball will launch straight forward. Any imperfection in your swing - dropping the rear shoulder, rolling over of the hands or misalignment, is expressed by the outward path of the ball. Take a set of swings off the tee with the flat side, then simply roll the barrel to the normal curved surface and see the dramatic impact this trainer makes. Offered in 33" 33 oz.
