Features & Facts

The key to effectively improving your pitch or hit is in the accuracy of the data


baseball seams

Yakkertech uses vision imaging technology to provide uncompromising ball kinematics for the purpose of analysis and iterative performance enhancement for pitchers.

Unlike most systems that employ radar technology, the Yakkertech device applies the only methodology capable of direct measurement of spin rate and spin axis. With the use of vision imaging technology, the actual movements of the baseball seams are identified, which allows for a very accurate calculation of the spin rate/axis.

Produced by long-time veterans in the sports imaging business, known for unprecedented work with golf ball kinematics, the Yakkertech team delivers a state of the art system that delivers real-time data to enable reactive training, operating within low margins of error.

Features & Facts


Release Velocity:
Speed of each pitch at the point of release, and as it crosses the plate. 

Horizontal and Induced Vertical Break:
Inches of break that resulted from the spin applied to a pitch. These values are in relation to a pitch on the same plane, and velocity, that has zero spin. This is the best way to quantify the “ride” of a fastball, or effective movement of a breaking ball.

Spin rate:
(measured in RPM’s): how fast the ball is spinning





How much possible late life is on that pitch for that certain velocity and spin axis

  1. You want every pitch except for a slider to be between 85-100%. A slider has the most gyro spin of any pitch, meaning it is spiraling dead straight more than any other pitch
  2. Efficiency: measures how the axis is correlated with the spin rate. The lower the percentage, the more the pitch is moving in a straight path, and not taking advantage of the spin rate. For example, two fastballs both with similar velocity and spin rate of 2400. Fastball #1 has a tilted axis causing movement, and thus taking full advantage of the high spin rate, would show 85-100%. Fastball #2 has a slight tilt of axis and a high degree of gyrospin. This scenario might show 40%, which means less movement of the ball and not taking advantage of the spin rate.

going to be between -180°and 180°. A slider will be the closest to -180°and 180° of any pitch. Axis refers to the direction of the spin:

The ball rotates on three planes— X, Y and Z. Gyrospin is the amount of spin in the “Y” direction. With the exception of the slider, you want this number to be very low.



Exit Velocity:

Two measurements – straight exit velo as the ball leaves the bat, but also hitter generated exit velo, which takes out the impact of the speed of the ball coming into the bat.

Launch Angle:

All angles are captured to help understand the direction and distance in the air.

Spin Rate & Spin Axis:

The rate of spin combined with the way in which the ball is actually moving around its axis – impacts the flight of the ball.

Hang Time & Distance of Hit:

Will show how long the ball was in the air, and how far it actually went. 

Contact Location

Relative to the back of home plate, this data will provide exactly where contact was made.



Stereo Vision
Mono Vision.


Stereo Vision vs. Mono Vision

Yakkertech's data collection benefits from the use of two cameras vs. just one. Think about how much more you can see when you look with both eyes open versus one. Our stereo vision technology uses what is known as "stereo triangulation" to determine the exact location of the ball while it is moving. Because mono vision cannot do this, it has a much higher error rate. In addition, stereo vision captures at least twice as many images of the ball than the current mono vision systems. This also leads to a more accurate set of kinematic data on each thrown ball.

& Storage.


Data Collection & Storage

This is such an important feature of the product. The Yakkertech system allows for a pitcher to work on a skill, then analyze the data for optimum numbers and a conclusion on what needs work. With our system, you can store data, adjust pitch for another round of practice, and then instantly compare your new data. Whatever you are doing to improve performance, you have instant feedback. And then the data is there forever for further reference.




The Yakkertech system can be used both indoors and outdoors, and thus is perfectly suited for baseball and softball training wherever it takes place. It can be moved about the indoor training center, and then outside on the practice field.

With Yakkertech, data capture is brought into the 21st century with an app that eliminates the use of "pad and pencil" data collection. All data goes right into the database system.


There is no other product on the market that can better help you improve the movement of a pitch or to add a pitch to your arsenal.
