Once the speedometer has calculated the difference between the pulses, it will convert it into a unit of measurement. In tennis, this will be either miles or kilometers per hour.

While it might seem like fun to grab a radar gun to find out how fast your eight-year-old can throw a baseball, it’s going to cost you.Find sources: "Radar speed gun"– news · newspapers · books · scholar · JSTOR ( August 2021) ( Learn how and when to remove this template message) The primary limitation of hand held and mobile radar devices is size. An antenna diameter of less than several feet limits directionality, which can only partly be compensated for by increasing the frequency of the wave. Size limitations can cause hand-held and mobile radar devices to produce measurements from multiple objects within the field of view of the user. Use a radar gun for tennis. You can use a radar gun to measure the speed of a served ball, which is similar to measuring the speed of the ball out of a pitcher’s hand in baseball or softball. You can often use the same type of radar gun for both sports. He had a recorded speed of 242.0km/h (150mph) at 2018 Wimbledon, but officials revoked the reading due to errors with the radar gun.

No more missed serves that upset your student and embarrass the coach. A tennis radar gun catches everything! There is no way any coach should even consider not having a radar gun device. Plus players can use it when they practice on their own. They can set up the radar gun on a tripod, use the Constant-On feature and look at their speeds at any time. Itʼs also incredibly accurate. This of course completely messes up your readings and limits the usefulness of the radar altogether! Nave, Carl Rod (2017). "Police RADAR". HyperPhysics.

You don’t need to break the bank, but it is also worth investing in a more sophisticated and well engineered speed radar if you are actually going to make use of it. As with most ball sport related technologies, there is a lot of variability in terms of quality and as the old adage goes, what you get is what you pay for.
