Protee VX Data in Detail

Protee VX Ball Data in Detail

Ball Speed

Ball Speed is one of the most important launch data parameters, indicating the speed at which the ball leaves the club face. This metric is crucial, as it directly affects the distance the ball travels. The ProTee VX Launch Monitor excels in capturing this data accurately, thanks to its high-speed cameras positioned overhead.

The VX records numerous images of the motion of the ball in it’s initial few inches of flight, recording the time it takes for the ball to leave the viewing window, which allows a simple calculation of speed.

Ball Speed

Back Spin

An essential piece of information for launch monitors is back spin. It controls the trajectory of a shot, how far it travels, and the ball’s reaction upon impact with the ground.

Protee Vx Screen Record

Side Spin

Side spin is the rate of spin on a hypothetical horizontal axis. In reality, the ball spins in a single direction— backwards and to one side—and has a spin axis. A ball’s ability to draw or fade as it flies is partially dictated by side spin (alongside club path and face angle).

Side Spin

Launch Direction

The angle formed by the target line and the ball’s initial trajectory after leaving the club face is known as the launch direction. This angle determines whether the shot will result in a push or a pull.

When combined with directional side spin, this can cause the ball to fade or draw back towards the target. However, if not executed properly, it could lead to a slice or hook away from the intended direction.

Launch direction is also referred to as side angle, horizontal launch angle or azimuth.

Side Angle Azimuth

Launch Angle

Launch angle displays the ball’s original vertical trajectory in degrees. It is the angle between the vertical path of the ball and the ground.

It is essential to optimise both the launch angle and spin rate when using long clubs in order to get greater distance.

Protee VX Club Data in Detail

Club Speed

Clubhead speed refers to the speed of the club just before it strikes the ball. This velocity is a crucial parameter for golfers to understand their swing’s effectiveness.

The Protee VX directly measures the speed of the clubhead, which allows for an accurate calculation of the smash factor, which we’ll delve into further below.

Typically, clubhead speed is recorded in miles per hour, though it can sometimes be measured in kilometers per hour. This precise measurement by the VX offers golfers a deeper insight into their swing dynamics.

Club Spped

Smash Factor

The smash factor is essentially the ratio of the ball’s speed to the club’s speed, serving as an indicator of how efficiently energy is transferred from the club to the ball. This efficiency varies with different clubs and their respective lofts.

For a driver, the ideal smash factor is generally considered to be around 1.5, representing an optimal energy transfer during the swing.

The Protee VX calculates the smash factor based on actual measurements, in contrast to some budget-friendly launch monitors that estimate it due to their inability to directly measure club speed.

Smash Factor

Club Path

An in to square to in club path, with the club face square at impact, would provide a flawlessly straight shot.

The club’s path can interact with the target line, as seen in the graphic below. In order to hit a beautiful baby draw, you might practice on an in to out club path. As an alternative, a power fade may occur from the out to in club path.

When attempting to groove in a specific shot shape, there are numerous other elements to take into account. You must be conscious of your face angle, club path, and face-to-path relationship.

Don’t worry if you’re a beginner golfer and this seems far over your head! You can enhance your skills by gaining knowledge about these factors and learning how to use them with the Protee VX!

Club Path

Face Angle

Face angle is the angle of the club face relative to the target line.

Imagine your club path is perfectly square to target at impact, but the face is a few degrees open. The ball will start straight and veer off to the right with a fade. A closed clubface (and a neutral path) will lead to a ball starting straight but drawing off to the left for a right handed golfer.

Face Angle

Club Face to Path

‘Face to path’ is one of the most complex parameters on this list of Protee VX data points, but it is one of the most important.

Note that both club path and face angle are measured in relation to the target line. Face-to-path combines the two and works out whether your club face is open compared to the club path, or closed.

A clubface that’s open relative to the path of the club will produce a fade, whilst a face that’s closed to the path will produce a draw.

If the club face angle is square to the path then the ball will travel straight down that path (which may be a push or pull depending on your club path).

Face To Path 1

Attack Angle

When approaching the golf ball, the angle of attack specifies whether the club is moving upwards or downwards relative to the ground. The attack angle might be either positive or negative. Using this data parameter in practice with the Protee VX can assist you in optimizing your ball hitting.

A positive attack angle indicates that you are striking the ball upwards, as many golfers do with their driver when the ball is teed up, as illustrated in the image below. A negative attack angle indicates that you are hitting downwards towards the ball, as is typical with irons and wedges.

Angle of attack is also known as Attack Angle.

Angle Of Attack

Dynamic Loft

The actual loft imparted to the ball at impact is referred to as Dynamic Loft. Another more complicated metric, dynamic loft, refers to the angle of the clubface in the vertical axis at the point of contact between club and ball when the ball is maximally compressed.

The dynamic loft, which is distinct from the launch angle, is a measurement of the amount of loft on your clubface when it makes contact with the ball. This is distinct from the static loft, which is the loft of the golf club when it is at rest.

Your attack angle, the flex in the shaft of your golf club, the compression of the golf ball, the face-to-path angle, and the impact point on the clubface all influence dynamic loft.

Dynamic Loft is usually a data point reserved only for the most premium launch monitors, so to see it on the list of data for the Protee VX is fantastic!

If the dynamic loft is too high, the ball will climb too high into the air and not travel as far as you would anticipate for your chosen club. A low dynamic loft will result in a low flying running shot, which can be useful at times but can be difficult to control.

Dynamic Loft

Lie Angle

The lie angle is the angle between the shaft and the ground when a golf club impacts a golf ball with the sole of the club parallel to the ground.

When the toe of the club rests on the ground, the lie angle can be too upright. This causes the club’s heel to hit with the ground first, sending the ball to the left.

A lie angle that is too flat means that the heel is pointed off the ground. In this case, the toe will contact the ground first, and the ball will most likely head to the right of the target.

Club Lie Angle

Impact Point

The exact location on the golf clubface where the ball makes contact at impact is referred to as the impact point. Golfers will seek to hit the centre of the clubface because it provides the most efficient transmission of energy to the ball and allows them to control loft, trajectory, and spin.

Impact point is measured in both vertical and horizontal distances from the centre of the clubface and is also known as strike pattern and impact location.

Again, this is a data point not previously seen at this price point, which is really impressive for the Protee VX!

Impact Point

Protee VX Shot Characteristics in Detail

Air Time

The amount of time a ball is airborne is called its flight time, which is equivalent to hang time.

By changing the emphasis from measuring driving distance to competing to see who can keep the ball airborne for the longest, this feature can bring a new and exciting dimension to group games. You can also practise and perfect your high-flying iron shots by keeping an eye on your flight time.

Distance To Apex

Would you like to strike shots with a gentle landing and high flight? If you aim to hit higher, more stunning shots into greens, optimizing the distance to apex height for a given club is key.

The ProTee VX Launch Monitor offers a calculated shot characteristic known as apex height, which helps you enhance your ability to land the ball softly and accurately on the greens.

Carry, Run and Total Distance

Carry distance, run and total distance describe how far the ball travels at each stage of it’s flight before it comes to rest.

Of course, you could have a low-running shot with low carry and high roll, or a high-soft landing shot with little roll. Being able to hit both is the mark of a better player! Protee VX will show you these parameters in detail.

Carry And Roll Distance 1

Angle of Descent

The angle of fall describes the steepness with which the golf ball will land. A high angle of descent refers to a high, soft landing shot, and a low angle of descent will be seen following a 2 iron stinger shot. Working on this parameter can help you improve your trajectory and distance control.

Flight Path

The Protee VX calculates all the above shot characteristics using the ball and club data measurements, then models this within the software to produce a real-time, 3D flight path within an impressively short time.


Offline refers to how far away from the target line the golf ball lands, in a horizontal plane. The ball could either travel straight to this spot (a push or a pull), or it could draw or fade. Lateral landing is also affected by environmental factors such as wind and is often referred to as Distance Offline or Lateral Landing.

Distance Offline

Which Data Parameters are not measured by the Protee VX?

The Protee VX offers an increaible suit of ball data, club data and shot characteristics, not previously seen at this price point. There are few data parameters not included with the Protee VX.

Those that are not included will generally only be available on the most premium launch monitors (eg Trackman 4 and GC Quad). They include the following:
