Golf Swing Groover Created For Our Own Needs

While testing the sweet spot precision training method, we started to look for a training aid that would allow successive hits with as little distraction as possible. There was nothing available that would satisfy our needs so we began to upgrade an already existing idea, "swing groover"—a ball hanging on a rope.

Rock solid

Our aim was to build a robust, reliable device, and now, after years of development and testing, the device is extremely strong with a rock solid build.

The rubber stopping member above the shaft prevents the ball from rotating around the axis and causes the ball to quickly return to its initial still position.


Real golf ball

Sg3000 is the only groover on the market that uses A REAL, STANDARD WEIGHT GOLF BALL (45g) for an authentic impact feel.

The ball hangs on a very high tensile strength climbing rope (330kg).


With the mat underneath, the ball lies 8 - 10 mm above the standing platform for iron shots. This corresponds to golf course conditions. Practically always, either on the fairway or in the rough, there is some grass under the ball, sometimes making it much higher than 10 mm off the ground.


Driver setup - the height of the ball adjustable to one's preference. Below the ball is unraveled cord that provides a braking function, causing the ball to quickly return to its initial still position.


  • REAL, STANDARD WEIGHT GOLF BALL for authentic impact feel.
  • No picking up the balls: No distraction between practice shots. No need to bend over to tee the ball.
  • Comes with two balls/ropes, one for driver one for irons. The ball, after being hit, comes back into its initial stationary position in about 5 seconds.
  • Comes with Impact-masking tape, which makes it a perfect tool for sweet spot precision practice.
  • The ball, after being worn out, is easily replaceable. It hangs on a very high tensile strength climbing rope (330kg). Hand-made ball-rope fixture for max. durability.

In combination with Dr. Scholl's Foot Spray or Impact-masking tape, it is PERFECT for practicing the most important (and the most difficult to master) basic element of the golf swing—Sweet Spot precision.

  • "It's an absolute must"

    The Groover is definitely the best device because it gives a golfer the chance to work on making actual changes to the golf swing without worrying about the ball flight. At the same time, you do develop feedback on how well the ball was struck. It's an absolute must in my personal training as well as my students.

  • "Great for practicing impact!"

    It is a great tool to use in the backyard to practice getting your swing to the correct positions, especially at the most important place: impact!

  • What about swing path and club face angles?

    “It’s about hitting the ball in the center of the club face and hitting it hard.”
    Bubba Watson

    Sg3000 is not meant to completely replace practice on the golf range and using high tech equipment. It is a tool specially designed for a comfortable and effective practice of the most important basics of the golf swing.

    To master the sweet spot precision is drastically more difficult than to adjust the swing path and club face angles. It can take years to master the sweet spot precision, even only close to that of tour pros, but you can adjust your angles and swing path in a lesson or two.

    Let us compare hitting a golf ball with shooting with a rifle. Golfers’ incapability to control the sweet spot precision can be compared to a ramshackle rifle. No matter how good the shooter is and no matter how precise he targets (aligns the angles of the rifle to the target), with a ramshackle riffle he will always be imprecise because the bullet leaves the barrel in a randomly different way.

    To accurize a ramshackle rifle can be a very difficult task and can take a significant amount of time; the barrel must have an absolutely uniform dimension (to a ten-thousandth of an inch) for the length of their bores in order to be accurate, and, there are other factors that might need to be worked on. However, once the rifle is accurate, it's all downhill from there.

    You take the improved rifle to a shooting range and although you aim precisely using scopes, the bullet might repeatedly miss the target in one direction. You adjust the scopes accordingly (angle of the barrel in relation to the target) and now the bullet hits the target every time.

    Similarly, adjusting the club face angles and swing path of a golf swing is really a piece of cake in comparison to mastering the sweet spot precision.

    So, you should not worry if the swing path or club face angles are one or two degrees off while committing your full attention to the sweet spot practice using the groover. The optimal scenario is that you combine your groover practice with that on the range. For example, during the week you practice at home on the groover, and then on the weekend, you go to the range. There you can fix any face/path discrepancies you notice and then bring the adjustments to your groover sweet spot practice. In this way, the discrepancies will be minimized and become negligible.

  • When can using the groover be a better choice in comparison to practicing on the range or with high tech golf simulators?

    When working on the shape of the swing and when working on impact location precision (sweet spot precision), because it allows you to detach from the result − the ball flight. It allows you to fully commit to these two important basics without worrying about the ball flight. Many pros hate sending their students to the training range before they learn proper swing sequence.

    When the aspiring golfer learns the swing technique (shape of the swing), he is not yet able to make solid contact with the ball. He goes to the training range to practice his new swing and because the balls fly all over the place, he thinks that something must be wrong with his swing movement and then he starts to tweak it. This is very detrimental because his inability to hit good shots might have nothing to do with the shape of his swing; he just hasn't yet developed enough skill to hit the ball solidly enough.

    Here is an example of how Johnny Miller, one of the legends, benefited from being prevented from seeing the flight of the ball and therefore was forced to focus solely on the impact:

    In the winters when I was a kid, my dad had me practice in the basement of our house. I'd hit balls for hours into a canvas tarp tacked to the ceiling. Because I couldn't see the ball flight, I relied on two kinds of feedback: how the shots felt and how they sounded. Thin shots, balls struck on the toe, and shots hit a shade fat have distinctive sounds. You're always looking for that crisp thwack at impact. Even from the TV booth, I can usually tell immediately if an iron shot is mis-hit and if it will come up short or not have enough spin to hold. Sound can definitely give you clues as to how well you hit the shot.

  • What max. clubhead speed is recommended for the groover?

    The device, the frame, can take any clubhead speed, however, to prolong the longevity of the ball, it is recommended to use clubhead speeds up to 110 mph.

    AMA (average male amateur) golfer's drive clubhead speed is 93.4 mph. LPGA Tour players swing is about as fast as the average amateur male.

    Under such conditions you should be able to use one ball/rope set at least for a season of regular use
