Launch monitors and simulator accuracy
Launch monitors and golf simulators have evolved over the years, with the technology becoming more accurate and sophisticated. Launch monitors are designed to measure and analyse various aspects of a golf shot, providing real-time feedback for players. The accuracy of these systems is dependent on the quality of the technology and other factors.
There are several methods used to track ball and club data. Photometric cameras take high-speed images through impact, which are then analysed to determine ball and club data. Doppler radar technology emits signals that are interfered with by the ball in flight, allowing the system to calculate various data points. Optical sensors, often placed inside a hitting surface, track the ball and club as they pass, determining the club path, horizontal launch direction, and ball speed. Infrared light systems track data as the ball passes through light waves, including ball speed, launch angle, and direction.
The most accurate systems combine two or more of these technologies to track both club and ball data. For example, higher-end launch monitors use infrared tracking with camera-based tracking for exceptional accuracy. Radar-based simulators, such as those using Doppler radar technology, can be as accurate as camera-based systems, although they may struggle to measure certain parameters like ball impact location.
The cost of a golf simulator or launch monitor is often indicative of its accuracy. Entry-level systems under $1000 will likely be less accurate, while those in the $4000-$10000 range can approach professional-level accuracy.
While golf simulators are generally accurate, there are limitations. Environmental conditions such as temperature, humidity, and elevation can affect the distance of shots, and certain building materials like metal roofs and steel walls can interfere with radar fields. Additionally, there is a difference of 1-3% in measurements between a simulator and real-life golf course performance, and they may not fully replicate the short game or putting.

Environmental conditions
Temperature, humidity, and elevation are critical factors that can significantly impact the distance of your shots, especially with longer clubs. For example, if you're from a region with high humidity, like Florida, and you use a simulator that isn't calibrated to match those conditions, you may find that the numbers suggest you're hitting the ball farther than you typically would in that humid environment.
The materials used for the simulator screens can also affect accuracy. Screens made of tightly woven polyester, such as the ImpactWhite® 350, are designed to withstand ball speeds of up to 150 mph while providing clear and sharp visuals. This durability ensures that the screen will last even with frequent use. Additionally, the ImpactWhite® 350 is ISF Certified for Accurate Color Reproduction, ensuring rich and vibrant colours that accurately represent the details of the virtual golf course, regardless of lighting conditions.
Another factor to consider is the physical space where the simulator is set up. Metal roofs, steel walls, and aluminium siding can interfere with radar fields, impacting the accuracy of radar-based systems. Therefore, it is crucial to choose a suitable space and consider the technology used by the simulator before setting up your simulator environment.
While advancements in technology have improved the accuracy of screen golf, it is important to acknowledge that real-world environmental conditions can still affect the overall precision of the simulation. These systems provide a good indication of your progress and can be highly accurate, but they may not always account for the complexities of real-world weather patterns and local environmental factors.

Radar interference
Overall, golf simulators are considered to be quite accurate. However, there are several factors that can affect the accuracy of a golf simulator, including the technology used, the quality of the system, and environmental conditions.
Radar-based golf simulators, such as the FlightScope Mevo, Garmin Approach R10, and FlightScope X3, use Doppler radar technology to track the ball's flight. These systems emit microwave signals that are interfered with by the ball as it flies through the air, allowing the system to calculate various data points. While these systems can be very accurate, they are susceptible to interference from certain materials and objects in their vicinity.
Metal objects, such as steel walls, garage doors, metal rails, and even appliances like refrigerators and air conditioners, can interfere with the radar fields and cause inaccurate readings. This is because metal is a reflective material that can disrupt the microwave signals emitted by the radar system. To mitigate this issue, it is recommended to remove or relocate metal objects away from the radar field of view.
In addition to metal objects, other electronic devices such as computers, TVs, and fluorescent lights can also cause interference. The user manuals of radar-based golf simulators typically provide guidance on how to minimise interference, such as by adjusting the placement of electronic devices or using microwave-absorbing materials.
While it is challenging to completely eliminate radar interference, especially in enclosed spaces like garages or basements, there are creative solutions that individuals have implemented. These include constructing vertical walls of water, using angled boards covered with metal foil, or employing metal mesh to diffract or reflect the microwaves away from the radar field of view.

Camera-based systems
Camera-based golf simulators capture high-speed images of the ball immediately after impact. Based on these images, various data parameters are derived, leading to the rendering of shot shape and distance. This includes launch angle, distance from the centre, backspin, and side spin.
These simulators can be used both indoors and outdoors, and they are considered quite accurate. The accuracy of a golf simulator depends on the quality of the system and other factors. The top golf simulators are nearly identical to what you would experience at a range or on a golf course.
The industry observes a difference of 1-3% for the same shot on a simulator versus outside on the golf course, which is very precise. However, it is important to acknowledge the limitations of golf simulators in replicating the short game, especially putting, and the total scores are often lower on the simulator than on the golf course.
In addition to the technology used, the accuracy of a camera-based system can be influenced by environmental conditions such as temperature, humidity, and elevation, which can affect the distance of the shot. Furthermore, certain materials like metal roofs and steel walls can interfere with the radar fields, impacting the accuracy of the ball flight metrics.
To ensure the best experience, it is recommended to choose a high-quality impact screen for a golf simulator. The screen material should offer image clarity, brightness, and colour accuracy. The ImpactWhite® 350, for example, provides exceptional image fidelity, a wide viewing angle, and is built to withstand high ball speeds, ensuring an immersive and durable golfing experience.
