TRACKMAN

GLOSSARY

Club speed: the speed of the center of the club face at impact (first contact with the ball)

Attack angle: the vertical (up-down) angle at which the club head is moving at impact. Positive means hitting up on the ball, while

negative means hitting down on the ball

Club path: the horizontal (left-right) angle at which the club head is moving at impact. Positive means to the right (inside-out for a

right hand golfer), negative means to the left (outside-in for a right hand golfer)

Dynamic loft: the loft (angle) of the part of the club that makes impact with and influences initial direction of the ball, relative to

vertical (vertical = zero degrees)

Face angle: the angle of the part of the club that makes impact with and influences initial direct of the ball, relative to the target

line (left-right). Positive means to the right (open relative to target for right hand player), negative means to the left (closed relative to

target for right hand player)

Spin loft: the difference between dynamic loft and attack angle. The spin loft is related to the static loft of the club, however shaft

flex and hands leading or lagging the club head will alter this.

Swing plane (formerly vertical swing plane): a measure of how vertical the swing is, where a high value represents a very up and

down (steep) swing plane and a low value a relatively flat (to the ground) arc. More technically, it is the angle made between the

ground and the plane of club head trajectory at the bottom of the swing arc

Swing direction (formerly horizontal swing plane): the orientation of the swing arc, relative to the target line, where positive

means to the right, negative means to the left. More technically, it is the horizontal direction the club head is traveling in at the bottom

of the swing arc

Ball speed: the ball’s initial velocity

Smash factor: the ratio ‘ball speed divided by club speed’, which describes the efficiency of impact. Note that the smash factor

depends on the spin loft and impact location, where the lower the spin loft the higher the smash factor and the more centered the impact the higher the smash factor

Launch angle (formerly vertical launch angle): the ball’s initial vertical angle relative to ground (horizon) level

Launch direction (formerly horizontal launch angle): the initial direction of the ball relative to target line. Positive means to the

right, negative means to the left

Spin rate: how many times the ball rotates per minute when leaving the club face. This is independent of the orientation of the spin

axis. Note that the spin rate drops during ball flight - typically 4% for each second

Spin axis: as the ball spins around an axis, the measure of axial tilt. Positive means the axis is tilted to the right (thus resulting in a

fade or slice for a right handed golfer), negative means the axis is tilted to the left (thus resulting in a draw or hook for a right handed

golfer)

Height: the apex point of the ball flight, measured relative to the height of the starting/launch position of the ball

Carry: how far the ball travels in the air. The number reported is carry “flat,” meaning how far the ball would carry if the ground were

perfectly flat relative to where the ball was launched from

Side: how far off-line the ball lands relative to the target line (right or left carry). Similar to carry, this is side “flat,” meaning how far the

ball would land off-target if the ground were perfectly flat relative to where the ball was launched from

Total: the sum of measured carry “flat” distance plus calculated bounce and roll. The calculated bounce and roll model depends on

three parameters measured by TrackMan: landing angle, landing spin rate, and landing speed

Side total: how far off-line the ball ends up, after calculated bounce and roll, relative to the target line (right or left). This is reported

“flat,” meaning how far the ball would end up off-line if the ground were perfectly flat relative to where the ball was launched from

Landing angle: descent angle of the ball as it lands (carry “flat” landing point), measured relative to ground level

Last data: distance at which TrackMan last recoded data. If the range is sloping upwards last data should be shorter than carry

“flat,” if the range is sloping downwards and the TrackMan radar has a line-of-sight to the landing area last data should be longer

than carry “flat”

Hang time (formerly flight time): elapsed time from impact to carry “flat”

Ryan Bonser PGA

With TrackMan, you have access to the most progressive and sophisticated performance enhancing software in the industry. The world's leading coaches and players are daily users and their insights and recommendations help us to constantly improve our suite of player development programs.

You also have access to hundreds of model swings from tour players and up-to-date stats through our work on the world's top tours.

26 TRACKMAN DATA PARAMETERS

We display a shot’s 3D trajectory together with 26 impact and ball flight parameters in real time.

You want to use the best so here it is.

When you start your lessons every shot will be recorded with 3 or more cameras. This gets uploaded to your account by the email you give me.

There you will find the information of all the shots taken during the lesson. This will be there so you can look at it now and forever.

You will love it!

Single radar unit has enjoyed the status of being the de facto training tool amongst the leaders of the game; from hundreds of PGA Tour players to thousands of coaches to every golf equipment manufacturer in the industry.

Why?

Because they trust it. Because it helps them perform better.

Because its single radar technology is unrivaled in its category.

Because it works.
