TrackMan 4 is a golf launch monitor that provides data on ball flight, club delivery, and ball impact. The accuracy of TrackMan 4 indoors depends on several factors, such as the quality of the indoor hitting area, the type of golf ball used, and the calibration of the system.
Generally, TrackMan 4 is designed to perform well in both indoor and outdoor environments, but there are some limitations to its accuracy indoors. For example, the ball flight data may not be as accurate indoors due to the limited space and lack of natural lighting. Additionally, the indoor hitting surface can affect the readings, as some surfaces may absorb more of the impact force and create inconsistent results.
That being said, TrackMan 4 is still considered one of the most accurate golf launch monitors on the market, and many professional golfers and instructors use it for both indoor and outdoor practice sessions. To ensure the most accurate readings, it is important to calibrate the system properly and use high-quality golf balls.
