The Pro-Slot Trainer fixes the most common power leak in golf: a collapsed lead arm and narrow swing arc. It gently limits your trail arm to a 90-degree slot position at the top of the backswing, creating the wide-to-narrow-to-wide arc that generates effortless distance.
Strap it on your trail arm and make swings. The trainer prevents the trail elbow from flying out or collapsing, instilling the feel of a tour-level arm structure. Once you groove the correct position, the width and extension carry over to your real swing without the training aid.
Works for full swings with any club. Lightweight and unobtrusive enough to hit real balls at the range while wearing it. Addresses the root cause of weak, inconsistent contact — not the symptoms.
