TrackMan is a sophisticated golf launch monitor that provides golfers with a wealth of data to help them improve their game. With over 40 different data points, it can be challenging to know where to start when interpreting TrackMan data. However, understanding key measurements can benefit golfers of all levels. This includes data on club speed, club path, swing direction, dynamic loft, face angle, face-to-path, launch angle, spin rate, hang time, landing angle, and total distance. By analyzing these parameters, golfers can gain insights into their swing mechanics, ball flight characteristics, and overall performance. Normalization is another important feature of TrackMan, allowing for accurate comparisons between different sessions or environments by accounting for factors like altitude and wind conditions. Ultimately, TrackMan's detailed data provides golfers with a powerful tool to enhance their skills, make adjustments, and achieve their desired outcomes on the course.

Club path and face angle
Club path refers to the direction the club head is moving (left or right) at impact. Most golfers relate this number to hitting the ball "in-to-out" or "out-to-in". If you are swinging from in-to-out, the number will be positive, meaning you are swinging to the right of the target line, and that will typically create a draw shape. Conversely, if you are swinging out-to-in, the club path number will be negative, indicating a fade or slice shape. The higher the number, the more shape you will get.
Face angle, on the other hand, is the horizontal direction in which the club face is pointing at impact. It can be open, closed, or square. If the club face is closed, it will point to the left and the Trackman number will show a negative value. Conversely, an open club face will show a positive number, while a square club face will be 0 degrees and pointing straight down the target line. The face angle largely determines the starting direction of the golf ball.
The difference between the face angle and the club path is known as the face-to-path. This is a key factor in determining the expected curvature (spin axis) of a golf shot. Assuming centred contact, the ball should curve towards the face angle and away from the club path if the face-to-path is not equal to zero. A positive face-to-path means the face is pointed to the right of the club path, while a negative value means the face is pointed to the left.
By understanding the relationship between club path and face angle, golfers can more easily make the golf ball do what they want and adapt their technique while on the golf course.

Attack angle
The attack angle can influence the golfer's potential distance and their ability to control the ball on approach shots. A positive attack angle, for example, is necessary to maximize distance with a driver. The attack angle also plays a significant role in determining the club path and the quality of the strike. It is also important to consider when optimizing spin loft, ball speed, and total distance.
The attack angle is closely related to the club path, which refers to the direction in which the golfer is swinging the club. An "on-plane swing" can result in an inside-out or outside-in club path, depending on the attack angle. A positive club path indicates a swing to the right of the target line, resulting in a draw shape, while a negative club path indicates a swing to the left, resulting in a fade or slice.
The attack angle is one of the critical parameters considered when fitting a golfer for a driver. It helps determine the optimal club path and improves the golfer's ability to control their ball flight. By understanding their attack angle, golfers can make better-informed decisions about their equipment and technique to optimize their performance on the course.

Hang time
The hang time of a golf ball is influenced by several factors, including the total distance travelled, apex height, and the amount of spin on the ball. The wind can also impact the hang time, but TrackMan's radar system calculates what the ball would have done in neutral conditions (80-degree temperature, no wind, etc.), providing valuable insights for golfers.
To increase the hang time, golfers can focus on optimising their swing. Studies have shown that a slower swing speed can lead to a higher trajectory, keeping the ball in the air for longer. Additionally, hitting up on the ball with the driver can increase airtime, although this requires a delicate balance to avoid poor contact and weak hits.
Instructors and golfers can utilise TrackMan's precise data on hang time to enhance their game. By understanding how different factors influence hang time, golfers can make informed adjustments to their swing mechanics and equipment choices, ultimately maximising carry distance and achieving the desired ball flight.
Overall, hang time is a critical aspect of golf performance analysis, providing actionable insights that can lead to significant improvements in a golfer's abilities.

Launch monitor
There are two primary types of golf launch monitors: radar and photometric. Radar launch monitors, such as the Trackman 4, use radar doppler technology to read the ball trajectory, spin, and more after the ball is struck. They typically sit behind the golfer. Photometric launch monitors, such as the Garmin Approach R50, sit next to or above the hitting area and take a series of photos of the ball as it is struck to calculate data.
When choosing a launch monitor, there are several factors to consider. Accuracy is paramount, as meaningful insights depend on precise data capture. You should also consider whether you need a launch monitor that can transition between indoor and outdoor settings, as well as its portability if you plan to use it in different locations. The range of metrics provided and ease of use are also important factors to ensure an enjoyable experience.
The Trackman 4 is widely considered the best golf launch monitor available. It is known for its extreme accuracy, versatility, and high-quality data. It provides over 40 data parameters, including ball speed, launch angle, spin rate, clubhead speed, and smash factor. With its dual Doppler radar technology, it captures data for the entire ball flight, typically lasting about six seconds.

Normalization
The normalization feature provides standardized information about a golf shot's carry, side, and total. It measures every shot's actual trajectory from launch to landing, and normalization provides information on the trajectory assuming calm conditions at any altitude and temperature input by the user. This feature is particularly valuable for gapping, fitting, and finding a golfer's "normalized" distances.
For instance, TrackMan can determine how a ball would have flown under calm conditions by using the baseline aerodynamic model and launch data (ball speed, launch angle, and spin rate). The user can change the altitude and temperature within the TPS software to their desired values. Normalization will then calculate the ball flight based on the launch data, initial trajectory, calm conditions, and the new altitude and temperature settings.

Frequently asked questions
Club Path is the direction you are swinging the club. If you are swinging from in-to-out, the number will be positive, meaning you are swinging to the right of the target line, and that will typically create a draw shape. A negative number means you are swinging out to in (swinging left), which will create a fade or slice shape.
Face Angle is the horizontal direction your club face is pointing at impact. This is crucial because it's the primary factor in determining where your ball starts its journey.
Hang Time is the total time a golf ball spends in the air from the moment it is struck until it lands. This measurement is essential for analyzing the overall flight of the ball, including its trajectory, distance, and behavior under different conditions.
