Weighing only 12 lbs. the Perfect Pitch is the lightest 45 MPH mechanical machine on the market. Plus, with Perfect Pitch's heavy-duty small structure, transporting is a breeze. Easily fits in your car or truck so you can quickly move from the backyard to the ballpark. Here's how it works: 1) Set your desired speed from 15-45 MPH by attaching the heavy duty spring to the foot pedal. 2) Set your pitch height on the throwing arm - ground balls, strikes, or fly balls. 3) Load a baseball or softball on the throwing arm. 4) Step on the foot pedal with your foot to apply spring tension. 5) Pull back on the release handle and throw a perfect pitch every time! Other mechanical machines are heavy, bulky, expensive, and difficult to understand all the components. With the Perfect Pitch, you'll get an affordable, accurate, light-weight, portable pitching machine that is simple to operate and perfect for both baseball and softball players. The Perfect Pitch is great for coach pitch, slow pitch, fast pitch, and league games.
