##### From the moment you call for your custom-fitting appointment Pure Performance Golf Labs guarantees impeccable, premium service. Our goal is to improve your performance and your pleasure and enjoyment of the game of golf. We promise the latest technology in the fitting experience and customization of your tailored clubs. We strive to maintain ongoing relationships with all of our customers.

## Club Specs Explained

During the fitting process you will hit a series of shots with your current equipment to determine starting point data. From there our team will determine the correct loft, lie angle, swing weight, shaft weight and frequency that archives optimal performance.

##### Club Length

Pure Science Labs custom measurements include height, posture and arm length to ensure a perfect club that swing consistently with solid ball contact.

##### Club Lie Angle

The club lie angle refers to the vertical face of the club head. This is a custom measurement with your height, arm length and specific swing factored into the equation. Custom club fitting by Pure Science Labs will help correct too flat or too upright lie angles vastly improving both distance and accuracy.

##### Club Loft

Club loft is the angle of the clubface which directly affects the distance and flight pattern when the ball is struck. During your Pure Performance Golf Lab club fitting session, the loft of each of your clubs will be measured prior to taking your launch readings. Our expert fitter will be able to determine the exact ideal loft for your clubs for maximum accuracy and distance.

##### Shaft Stiffness

Shaft stiffness is the ability of the club shaft to bend or flex when force is applied. Our professional club-fitter will recommend the ideal shaft for you based on swing speed and tempo. Pure Professional Golf Labs has the latest in shaft technology and a range of shafts with graphite, steel and composite blends. Your unique swing will determine your own ideal shaft.

##### Swing Weight

Swing weight is a term which describes how the weight of the club feels when you swing it. It is also a balance of measurement which describes the degree to which the club balances toward the clubhead.

Our Pure Science Labs expert fitter can customize your clubs to find the optimum swing weight for your individual swing. We do this by changing grips, clubheads, and shafts and adding different fill materials inside shafts and club heads. Sometimes clubs feel too heavy or too light and this negatively affects performance. You will find your custom clubs are ‘just right’!

## TrackMan Technology

**Club speed**

The speed of the center of the clubface 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 clubhead 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”
