Swing Perfect! is a revolutionary golf swing trainer that helps you set the perfect swing path into your muscle memory. Swing Perfect is a swing trainer that analyzes swing plane and club face position simultaneously through your complete swing and gives you immediate, continuous feedback when you swing any club, indoors or out, at home, on the driving range, even on the course. Included is an instructional video on how to use SwingPerfect!. Swing Perfect is universal for both right and left handed golfers. The Swing Perfect trainer uses advanced electronic microcircuitry, a minature swing analyzer gyroscope and a unique four-position switch to help align your swing to within 3 degrees of the perfect plane. If you move beyond the plane, don’t rotate or transfer your weight correctly, you’ll feel a slight vibration in the grip, just enough to alert you change what you’re doing. Swing Perfect! is manufactured by a leading ISO certified aerospace firm and calibrated to 0.010 of an inch tolerance. The SwingPerfect trainer is durable, with no mechanical moving components within the swing sensing system. ***Due to state regulations restricting the usage of Mercury in electronic switches, we cannot ship the Swing Perfect to the following states, CA, CT, IL, ME, NY.
