Abstract: A golf swing analyzer providing a learning tool for golfers to help improve golf backswing and club face angle consistency. To gage the club angle relative to swing path, a fence is placed and held on the shaft perpendicular to the club face. During a golf swing, an air flow along this fence is created by the swinging motion of the club. For a perfect square shot, the pressures are equal on both sides of the fence; otherwise, as the fence angle changes relative to air flow, one side compacts the air, creating a high-pressure area while at the same time the opposite side dams the air flow and creates a low-pressure area. A differential pressure transducer detects this pressure difference on each side of the fence. When the ball is struck, a microphone in the device detects the ball impact and a microprocessor interprets the fence position relative to air flow based on the pressure transducer output.
