The ball drops the instant your form breaks — so you feel the fault and fix it before your next swing. The "chicken wing" — your trailing elbow escaping your body on the downswing — is one of the biggest causes of the slice and lost distance in amateur golf. Most golfers have it and never feel it happening. The ArmPlane Smart Ball makes it impossible to ignore. Hold the lightweight inflatable ball between your upper arm and chest and swing. Keep your arms connected to your body and the ball stays put. Break the connection and it drops — instantly, every time. No mirror, no video, no coach required. Train the feeling a few minutes a day and the connection becomes automatic — the same move you see on tour players at impact. HOW TO USE: Place the ball between your upper trailing arm and chest (right arm for right-handed players). Make slow practice swings at home or at the range. If the ball drops, your arms have disconnected — reset and go again. Aim for 20 clean swings per session.
