Golf Monitoring: What To Track And Why

what should you monitor golf

Launch monitors have become ubiquitous in golf, with professionals and amateurs alike using them to improve their game. These monitors use ultra-sophisticated algorithms to interpret ball flight and provide data that can be used to improve performance. They measure a variety of metrics, including clubface angle, launch angle, spin-tilt axis, club path, face angle, and dynamic loft, to help golfers understand their strengths and weaknesses. While some launch monitors can be expensive, there are also budget options available that can provide valuable insights without breaking the bank.

Launch monitors

There are two main types of launch monitors, both of which use sophisticated algorithms to interpret ball flight: those that provide club data and impact detection, and those that do not. The former, such as the FlightScope Mevo Plus, are generally more expensive and offer a more comprehensive understanding of a player's swing. However, more affordable options like the Rapsodo MLM and the FlightScope Mevo are also available and can provide valuable insights to improve performance.

"Face Angle" or "Delivered Face Angle" is the direction the club face is aimed relative to the target line at impact. An open club face points to the right of the target, while a closed club face points to the left. "Delivered Lie Angle" dynamically measures the club face relative to the ground, indicating how "toe up" or "toe down" the club is at impact. "Low Point" measures the distance between the swing's low point and the golf ball, helping golfers optimise their contact with the ball.

Spin-tilt axis

A positive spin-tilt axis, indicated by a positive number on launch monitors, will result in a shot curving left to right. Conversely, a negative spin-tilt axis, denoted by a negative number, will cause the ball to curve right to left. The magnitude of the spin-tilt axis value also influences the type of shot; larger numbers correspond to sliced and hooked shots, whereas smaller values are associated with fades and draws.

To achieve a straight shot, golfers aim for a spin-tilt axis between \-2 and 2, as it is challenging to visually discern any curvature within this range. A zero spin-tilt axis indicates a shot with no curvature, akin to an airplane flying straight with its wings parallel to the ground.

Controlling the spin-tilt axis allows golfers to shape their shots intentionally. For instance, a slight negative tilt produces a gentle draw, while a small positive tilt creates a controlled fade. Additionally, by optimising the spin-tilt axis, golfers can improve their clubhead speed and overall golf distance. This is because a more predictable flight path boosts confidence, enabling golfers to generate efficient power and maximise carry.

Club path

The Club Path is integral to the curvature and starting direction of the shot. For a right-handed golfer, a positive Club Path value denotes an 'in-to-out' swing, resulting in a draw. Conversely, a negative Club Path value represents an 'out-to-in' swing, producing a fade. To achieve a straight shot, the Club Path should be zero, indicating a neutral path with the club face square to the path.

The optimal Club Path depends on the intended shot shape. For instance, a golfer aiming for a 5-yard fade would require a different Club Path than someone trying to achieve a 10-yard draw. Understanding the Club Path is crucial for golfers to make intentional adjustments to their swing and consistently hit their desired shots.

Launch monitors have revolutionized the way golfers analyse their swings. These devices provide precise insights into various metrics, including Club Path, that were previously challenging to observe with the naked eye. By reviewing the Club Path data, golfers can identify patterns and make informed decisions to improve their performance.

Instructors also benefit from the quantitative data provided by launch monitors. They can quickly identify areas requiring improvement and make targeted suggestions to their students. For example, if a golfer is consistently exhibiting an excessively negative or positive Club Path, the instructor can recommend adjustments to the Face Angle to promote straighter shots.

Face angle

The face angle is influenced by the golfer's grip, ball position, hand position at the top of the swing, and position of the hands at impact. It is also related to the club path, which is the swing path of the club head relative to the target line. The club path can affect the initial direction of the ball, but to a lesser degree than the face angle. For example, on iron shots, face angle is approximately 75% responsible for the initial direction of the golf ball, while club path accounts for the remaining 25%. On shots with a driver, the face angle becomes even more important, contributing about 85% to the initial direction.

The optimal face angle depends on the type of shot the golfer wants to play. For a fade shot, the face angle needs to be left (closed) of the target at impact, while for a draw shot, the face angle needs to be right (open). An open club face points to the right of the target, while a closed club face points to the left. It is important to pay close attention to the face angle at address, and golfers can use a face alignment tool to ensure the face aim is correct.

The face angle is also related to the dynamic loft or impact loft, which is the effective delivered loft of the club face at impact. Higher lofted clubs should generally lead to higher launch angles. Good club fitters can help golfers find the right balance between spin rate and launch angle. Additionally, the spin-tilt axis, which is the axis that the ball rotates around, can affect the shot's shape and lift. A shot with a spin-tilt axis to the right will curve left to right, while a spin-tilt axis to the left will curve right to left.

Launch angle

A higher launch angle results in a higher ball flight, while a lower launch angle produces a more piercing trajectory. The ideal launch angle varies depending on the type of shot, the club being used, and the golfer's swing characteristics. For example, a higher launch angle is generally desirable for drivers to maximize distance, while a lower launch angle is preferable for wedges to execute bump-and-run shots.

To optimize launch angles, golfers can adjust their swing mechanics, ball position, and tee height. A shallow angle of attack and positioning the ball slightly forward in the stance tend to produce higher launch angles. Conversely, a steeper angle of attack and moving the ball slightly back in the stance result in lower launch angles. Additionally, launch monitors and swing analysis software provide valuable data and feedback to help golfers fine-tune their launch angles for improved performance.

It's important to note that while launch angle is crucial, it's not the only factor influencing shot outcomes. Other factors, such as club path, face angle, and spin rate, also come into play. Therefore, golfers should strive for a combination of optimal launch angles and other well-executed mechanics to achieve the desired shot results.
