Frequently Asked Questions

The Vector® Ball is a Speed of Recognition / Cognitive Vision Training (CVT) device.  It can be caught, thrown, bounced, etc. and used to support a full spectrum of live action vision training drills.  It is useful for practically any athlete, youth to professional, and helps improve performance regardless of the sport.  The Vector® Ball’s patented technology represents the most versatile vision training device available.


Cognitive Vision Training CVT, sometimes referred to as Vision-Based Speed-of-Processing (VSOP) training, are exercises that develop information processing ability, specifically visual information.  Regular athletic training consists of drills conducted in accordance with the provided instructions, i.e. the athlete knows exactly what is required before the drill begins.  CVT is when the athlete does not know exactly what is required when the drill begins, and must accurately process visual information during the drill to be successful.  For example, if the athlete sees “A” during the drill then they must do “X”, if the athlete sees “B” then they must do “Y”, etc.  CVT exercises the mind’s ability to process visual information.  This is done by introducing unpredictable visual information during the drill that provides instruction on what is required to complete the drill.

It has a hard center core about the size of a golf ball that protects the electronics.  The core is surrounded by a clear thermoplastic (rubber like) shell that absorbs extreme shock and gives the ball its shape and look.

It is approximately the size and weight of a baseball (9 inches in circumference and 5.25 ounces).

The Vector® Ball emits a short burst of light, randomly changing the color of the Ball (red, green, or blue) each time it is struck, bounced, caught, etc. This provides athletes with unpredictable visual information that enables, live action, cognitive vision training (CVT) drills.

The Vector® Ball is very firm but not hard like a baseball.  It is firmer than a new tennis ball but can be compressed with a strong squeeze.

The Vector® Ball is very durable.  It can be run over by a car and thrown against a brick wall repeatedly at game speed without damaging the Ball or affecting performance.  The Vector® Ball was originally designed to withstand being hit with a baseball bat by youth athletes to teach them to keep their eye on the ball and see the impact.

The Vector® Ball is resistant to weather and can be submerged in water without damaging the Ball or effecting performance.  However, prolonged expositor to the elements (sun, snow, dirt, etc.) can degrade the Ball.

The Vector® Ball randomly and instantly changes color (red, green, or blue) with each impact.

The Vector® Ball requires a firm impact to change color.  It will not change color when thrown or shook.  It will only change color upon a firm impact with a wall, floor, hand, glove, etc.

The batteries are not rechargeable however they are the highest quality available.  Battery life is dependent on cycles and durations of use (workouts) however, the Vector® Ball is engineered to provide over six (6) months of live action cognitive vision training (CVT).

The Vector® Ball changes color for a split second upon impact and then locks-out for ½ a second before resetting.

The Vector® Ball can be used in practically any sports training environment.  However, the color change, generated via a pulse of colored light, is more difficult to see in direct sunlight.  Vector® Ball colors are easily seen in brightly lit facilities or in covered outdoor facilities.

The Vector® Ball is a speed of reaction, cognitive vision training (CVT) training device.  Training with the Vector® Ball improves the athlete’s ability to process visual information and enhances their mental awareness during the full spectrum of game situations regardless of the sport.

Vision training with the Vector® Ball improves the athlete’s ability to process visual information and enhances their mental awareness during the full spectrum of game situations regardless of the athlete’s age or skill level.

The Vector® Ball can be used to transform standard training drills into cognitive vision training (CVT) drills.  The number of training drills the Vector® Ball can be used in are infinite.

Terms of Use

Inspect Vector® Ball prior to each use.  Before using the Ball conduct a visual inspection checking for signs of damage, including but not limited to rips, cuts, holes, or gouges.  Do not leave Vector® ball outside, as prolonged exposure to elements (sun, rain, etc.) can degrade the Ball.  The Vector® Ball contains electronic components housed within a hard-protective casing inside the ball.  If the outer shell is damaged it is possible that the hard casing could separate from the Ball and strike a person or property.  Do not use if damaged and stop using immediately if damage is noticed.
