Golf launch monitors are devices that employ advanced technologies such as radar, cameras, and infrared sensors to track and analyse various metrics of a golfer's swing and ball flight. These metrics include club speed, ball speed, launch angle, spin rates, and more. This data is immensely beneficial for golfers as it provides valuable insights into their performance, helping them understand their strengths and weaknesses. Launch monitors can be used both indoors and outdoors, with portable models available for outdoor practice sessions. They are versatile tools that cater to golfers of all skill levels, from beginners to professionals, and are designed to improve their game and optimise their equipment choices. Launch monitors work by capturing images or tracking the ball's flight using radar, and then mathematically analysing the data to provide feedback on the golfer's technique and performance.

What You'll Learn
Radar-based launch monitors
In its simplest form, a radar system sends out a radio frequency from its transmitter, which reflects off the golf ball and returns to the receiver. This allows the radar to plot the trajectory of the golf ball and produce a trace of its flight. The internal computer within the launch monitor then calculates the set of launch conditions that would have caused that particular ball flight and shot shape.
A key strength of a radar system is its ability to show how far and where the golf ball has travelled for each shot. This is why radar-based launch monitors are often used for shot-tracing on television coverage. However, using this method can cause issues when it comes to calculating the launch conditions, as the golf ball has already travelled a significant distance before the radar has enough data points to calculate from.
Doppler radar launch monitors work by sending out a radio frequency that reflects off the golf ball and returns to the receiver. This frequency shift allows the launch monitor to track the spin of the ball by analysing the difference in speed between the top and bottom of the ball.
Trackman, a popular radar-based launch monitor, features an inbuilt camera with two bespoke ultra-sensitive radars. This hybrid device’s multi-sensor technology synchronizes the inbuilt camera with its patented OERT (Optically Enhanced Radar Tracking) system.

Camera-based launch monitors
Photometric launch monitors typically sit right next to or above the hitting area, and take a series of photos of the ball as it is struck to calculate data. The images are then compared to measure how the ball is moving immediately after impact. Camera-based launch monitors process launch information through a ball-flight model to show the flight that the launch conditions would have caused. The quality and quantity of the images, and the launch monitor's ability to extract the necessary measurements, will determine how accurately the launch monitor can report the launch conditions and the resultant ball flight.
An important strength of a camera-based launch monitor is that it can take direct measurements of the launch conditions. It can tell the golfer exactly how their technique is affecting the golf ball, without interference from downrange conditions. This is known as closed data. The Foresight Sports GCQuad uses four ultra-high-speed cameras to take up to 200 images of the golf ball within the first 30cm of ball flight. Taking the images from four different perspectives allows the GCQuad launch monitor to produce a 3D picture of the golf ball’s movement, while the high-resolution cameras allow the system to clearly see the dimple pattern of the golf ball. This is a vital component when trying to measure spin.

Infrared methods
Infrared launch monitors work by querying IR sensors at a high frequency to detect when the ball "shadow" moves past them. This provides data on the launch direction and speed. Overhead infrared camera models use infrared light to improve their view of the hitting area without shining bright lights down from the ceiling.
Infrared launch monitors can be used in combination with high-speed, high-resolution cameras to capture thousands of images per second and build a virtual 3D model. This allows for a more complete and accurate picture of performance by measuring various data points. These data points include the spin-tilt axis, clubhead velocity, and the contact point of the golf ball on the club face.
Infrared launch monitors are generally easy to set up and can be used both indoors and outdoors. They are more affordable than other types of launch monitors, with prices ranging from $500 to $700. However, they may not provide the same level of accuracy as more expensive models.

Indoor and outdoor use
Launch monitors are devices that use advanced technologies such as cameras, radar, or infrared sensors to track and provide data on various metrics of a golf shot, including club speed, ball speed, launch angle, and spin rates. They are used by golfers to gain insights into their swing mechanics, identify areas for improvement, and make more informed equipment choices.
When it comes to indoor and outdoor use, there are a few factors to consider. Firstly, space requirements differ between indoor and outdoor settings. For outdoor use, there is usually more space for the ball to fly, which is advantageous for launch monitor readings. Indoor use, on the other hand, requires sufficient space to accommodate a full swing and the placement of the launch monitor. A minimum ceiling height of 9 feet, a width of at least 10 feet, and a depth of around 15 feet are recommended for indoor setups.
The type of technology used in the launch monitor can also impact its performance in indoor and outdoor settings. Camera-based monitors require good lighting conditions and may struggle with changing light or low-light conditions outdoors. Therefore, they are often better suited for indoor use. Radar-based monitors use Doppler radar to track the flight of the golf ball and are generally more suitable for outdoor use. However, radar-based monitors may be less accurate in certain outdoor conditions such as rain or fog.
Some launch monitors are designed for both indoor and outdoor use, offering versatility and portability. For example, the Foresight GC3/Bushnell Launch Pro is known for its accuracy in both indoor and outdoor settings. The Mevo+ by FlightScope is another option that can be used both indoors and outdoors, although it is particularly well-suited for golfers with indoor hitting spaces due to its impressive simulator feature. The SC4 Pro is another versatile and budget-friendly option, offering both indoor and outdoor capabilities for under $500.
When choosing a launch monitor for indoor and outdoor use, it is important to consider factors such as space requirements, lighting conditions, technology type, accuracy, and portability to ensure the device meets your specific needs and preferences.

Improving your game
Launch monitors can be an incredibly useful tool to help golfers improve their game and optimise their equipment. They can be used both indoors and outdoors, and work by tracking the flight of the ball and the swing of the club. This data can then be used to help golfers understand their performance and identify areas for improvement.
There are a few different types of launch monitors, each with its own strengths and weaknesses. Doppler radar launch monitors, such as Trackman, work by sending out a radio frequency that reflects off the golf ball and returns to the receiver. This allows the monitor to plot the trajectory of the ball and predict the outcome of the shot. Radar launch monitors are often used at driving ranges as they have unlimited ball flight to gather data. They are also good for showing where and how far the ball has travelled.
Camera-based launch monitors, such as Foresight, work by taking multiple images of the golf ball as it moves through the monitor's launch window. These images are then compared to measure how the ball is moving immediately after impact. Camera-based launch monitors can provide direct measurements of the launch conditions and can tell the golfer exactly how their technique is affecting the ball. They are also able to create 3D pictures of the ball's movement, which is useful for measuring spin.
Infrared launch monitors are another option, although they may not be as accurate as the other methods. These work by detecting when the ball "shadow" moves by two rows of IR sensors, which can give you the launch direction and speed.
Launch monitors can provide valuable insights into your performance and help you to identify areas for improvement. They can also be used to assist in selecting the right clubs and balls for your game. When choosing a launch monitor, consider your budget, the features you need, and whether you have sufficient space and lighting for indoor setups.
