This high-speed training tool allows the batter to see, track, and practice hitting 6 different baseball pitches at speeds up to 65 mph. A quick jerk of the handles speeds the ball down the cords to the hitter. The ProZip SpeedToss is used with metal and wood bats. The device teaches the highly acclaimed "top-half" hitting technique. The ProZip cords serve as a "swing guide" to help batters develop great line drive swings. The device sets up in seconds and is great for team and home use. The device is suitable for advanced users including high school and college teams. The ProZip SpeedToss can be used indoors and out doors. It is a great pre game warm-up. The pitcher "pitches" the ball to the hitter by jerking the handles apart. The pitcher holds the handles with the cord fully extended, positioning his hands together with palms facing inward and the knuckles slightly touching. The ball should be near the handles to start the pitching process. To throw a pitch, the pitcher pulls the hands apart sending the ball to the batter. The quicker jerk, the faster the ball will travel.
