Easton knows the needs of every player. Now with the Thunderstick, Easton offers a unique hand-eye training aid. The Thunderstick is a training bat that drastically helps improve hand-eye coordination. Hand-eye coordination is a vital part of successful hitting, and without it, hitting at your potential is virtually impossible. The Thunderstick T10 is a training tool that forces the hitter to make contact with the ball using a smaller bat. Using the Thunderstick at bat, you're training yourself to make contact at the sweet spot of the bat. The Thunderstick training tool works best when used with soft toss drills, and if you can hit with a 1" barrel, imagine what you will be able to do with a standard 2 5/8" barre!.
