For OVER 20+ YEARS the original Hitting Disk has been the batting aid of choice for Baseball and Softball players of all ages and skill levels looking to improve their swing. Simply throw the Hitting Disk and watch the way it flys to get instant feedback/results on your swing mechanics/technique! This training tool self teaches proper: swing path, swing plane, swing direction (staying inside the ball)/follow through(staying through the baseball), launch/approach angle, point of contact, hand position at contact (palm up palm down), short to the ball and staying long through it, plus much more to help master your swing and make solid contact more consistently! For example if you struggle with rolling over, the Hitting Disk will fly into the ground shortly after release to the pull side, if you struggle with dipping your back shoulder and casting the disk will fly up and to the opposite field side, stay through the ball and have the correct launch angle and the swing disk will fly long and far head high straight back towards the pitcher/center fielder. As all elite hitters know the most important part of a baseball/softball swing is the swing path/plane... and as parents know the ability to make quality and consistent solid contact with the ball is the difference from playing and sitting the bench. The Hitting Disk reinforces/analyzes a simple, yet important fundamental bat-swing motion and allows you to properly repeat it over and over without fatigue and strain while being fun to use, safe (no flying bats or hard balls), inexpensive, and endorsed by pros/hitting coaches because it gets effective results! Great for one (1) or two (2) handed drills! You don't need any coaches, balls, or a field to get the perfect swing and break bad habits! The Hitting Disk can be safely and effectively used in small spaces such as indoor cages/nets, garages, backyards, and large areas such as outside fields, parks, pregame warmup etc.
