Why Golfers Trusted The Gatekeeper To Improve Their Start Line And Face Control
Featuring Stewart Cink using the original Gatekeeper training aid.
Watch how simple feedback helped golfers build a more consistent, repeatable stroke.
What Makes The Gatekeeper So Effective
Instant feedback tells you immediately if your putter face is square, so you can start the ball on your intended line every time.
Build a square, repeatable motion through simple feedback instead of complicated mechanics.
Eliminate guesswork and create consistency you can trust on the course.
Lightweight, compact design. Set it up in seconds at home, indoors, or on the green without needing extra equipment.
Trusted by golfers worldwide. Thousands of players have used the Gatekeeper to sharpen their start line and build confidence.
Start with the largest ball for a generous margin, then drop to a smaller one as your stroke tightens. The gate gets harder, the feedback gets sharper.
How It Works
Clip the Gatekeeper to the lower third of your putter shaft. The ball hangs from the cuff, sitting just above the gate.
Address your putt. Make your stroke.
A square, on-path, tempo-controlled stroke swings the ball cleanly through the gate. Any deviation — a yanky takeaway, a face rotation, a rushed transition, a decel through impact — and the ball clips the gate. You hear the click. That's the miss.
Adjust. Repeat. Groove the stroke that doesn't make the click.
Introducing The Original Gatekeeper Training Aid
Stroke path. Straight-back, straight-through. Or the slight arc, repeated. The pendulum exposes both.
Face rotation. A rotating face shifts the ball off the swing plane. The gate catches it.
Tempo. Rushed transitions break the pendulum. The gate catches that too.
Ball-front stability. Use the front gate alone to stop the takeaway from sliding the ball off your aim.
Start Large. Shrink The Ball As You Improve.
The Gatekeeper ships with multiple ball sizes, and that's the training progression built into the product.
Begin with the largest ball. It gives you a generous margin through the gate, so you get clean reps early and learn what a good stroke feels like rather than fighting constant feedback.
As the strokes get cleaner, drop to a smaller ball. The margin shrinks, the gate gets less forgiving, and faults that used to slip through start showing up again. Same drill, tighter tolerance.
