3D Motion Capture


GEARS is a full-swing club- and body-tracking system used by PGA pros, club fitters, and club manufacturers to measure and analyze every nuance of a swing, in FULL 3D, from address to follow-through. Built on the same technology used by biomechanists and filmmakers, GEARS is the most advanced motion capture solution developed specifically for golf.

Schedule your GEARS Session!
The Leader in 3D Motion Capture

< 0.2mm Accuracy

Through eight high-speed cameras mounted all around the golfer, GEARS can accurately measure over 40 motion capture points to less than 0.2mm of error!

Your game deserves the best!

Most systems rely on low resolution approximations of swing data, with algorithmic estimates filling in the gaps. GEARS provides hard data, actually measuring the entire swing as it unfolds.

Data. Lots of data. GEARS instantly analyzes over 700 3D motion captured images per swing. Between the club and the body, over 40 3D markers are tracked. GEARS provides significant insight into how the club and body move throughout the swing.

GEARS Club Data

  • Full Swing Path
  • Impact Location
  • Clubhead Speed
  • Deflection Droop
  • Shaft Deflection
  • Face Heading
  • In/Out Path
  • Loft
  • Lie
  • Angle of Attack

GEARS data is used by FlightScope, Trackman, and other launch monitor companies to verify their club data! It’s that accurate.

GEARS Body Data

  • Shoulder Angle
  • Hip Angle
  • Knee Angle
  • Toe Angle
  • Spine Angle
  • Major Body Lines
  • Kinematic Sequence

GEARS also measures things like pelvis or rib translation (lateral and vertical movement) and allows you to compare your swing to any other one in the system: whether that’s a previous swing you’ve made or an LPGA or PGA Tour player’s swing.

Please wear tighter fitting shirts, bottoms with belt loops, and a baseball cap when you come for a GEARS session.

This player kept delivering a face open to the path. So, we sought to "change the picture." If you can do it at slower speeds, you have a chance at higher speeds.

Thanks to @gears.sports for the measurements. #GetInGEARS

This @gears.sports video demonstrates a small change we made with a good player. His driver was laid off a bit, too "shallow," and he had trouble controlling the downswing and impact location as the club wanted to "torque out" (his words) or steepen during the downswing. ...

Doing a little fine tuning with a driver today. Spin loft started below 6 (6!!) and ended up at about 9-11. Swing speed comfortably 118-121, peak height 108-112. Flushed this one! #GetInGEARS ...

The average axis tilt of a selection of some of the better @pgatour and @lpga_tour players in @gears.sports.

Much of the axis tilt comes late in the downswing, even with the driver.

Note that these are averages. There’s a bit more data here (https://thesandtrap.com/forums/topic/112097-gears-pro-data-axis-tilt-drivers-and-irons/) including max, min, standard deviation, and the two quartiles.

Working on less axis tilt at impact (94° is exaggerated in the other direction here). Axis tilt is a “right” path piece, and this player was attempting to match a “left” hand path piece with too much axis tilt at 18-20°. We flipped those: hand path now more right, axis tilt and rotation more left. #GetInGEARS #golfevolution #golf

Schedule your @gears.sports session with me and get your game in GEARS.

Warmup before a baseline @gears.sports session with a long-time student and a hard worker. This ended up being a session that would have been tough to do without GEARS as we changed things by an inch or a few degrees. #golf #golfevolution #GetInGEARS

If you’d like to get your game in GEARS reach out to me.

It’s *really* getting good now. Some of the tougher things to change are the compensations you once added in order to hit the golf ball solidly. Removing them because they no longer require that compensation requires a small leap of faith. @gears.sports measures everything and lets you know immediately if you’re leaping in the right direction. #golf #golfevolution #GetInGEARS ...

Does your lead hip motion more closely resemble the left/gold golfer or the right/blue golfer?

Video on this coming soon(ish)…

#golf #golfevolution #GetInGEARS

Here’s some “late” “early extension” as seen on @gears.sports.

The gold golfer is in “decent” shape for the first chunk of his downswing, then thrusts a bunch during the second half. The blue golfer continues to stay in forward bend and crank the left hip deeper, which doesn’t push the right hip toward the ball.

This kind of stuff is tough to see even in high speed video. Find yourself an instructor with @gears.sports (I’d say or an equivalent but nothing really is) or get in touch with me to #GetInGEARS. #golf #golfevolution

This is the worst toe hit I’ve seen on my @gears.sports system yet. And YES, your club *actually* does that, especially when it’s 97 MPH off the chrome. 😜 #golf #golfevolution #GetInGEARS ...

If you record your golf swing (and who doesn’t?), it’s critical to put your camera in the right place, or things may not appear as they really are. No more recording from high above the target line! @gears.sports #golf #playbetter #golfevolution

If you set up with the weight in your heels and extend your trail knee too much in the backswing, try pushing down with your toes! It might help you like it helped my student today! #golf #golfevolution #playbetter #GetInGEARS ...
