Radar Guns: Tool to Improve Tennis Serve Speed

A radar gun is easy to use, the device measures the speed of everything from baseballs, to people running, to cars driving. They claim to also measure tennis ball between 6 and 110 miles per hour up to 90 feet away on accuracy.

A radar gun is a device that measures the speed of an object that exceeds its field of vision.

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.

A tennis radar gun using the Doppler Effect is often employed for the tennis serve speed measurements. It is well known that such guns virtually always measure the line-of-sight or radial velocity of the ball and as such will return a reading less than or equal to the actual speed of the ball.

It let the player or trainer know about the speed they hit the ball at, and then measure that rate so that when they hit it, they get a feel for how fast they should swing racket-head speed-wise.

Improves the ability to tell your students how much they have improved every time they come out onto the court.

  • 76-105mph – Fast! People would do well to get the ball.
  • 51-75mph – pretty darn good! Thatʼs quite the arm you have there!
  • 21-50mph – the speed of your shot is pretty average; although it can be improved.
  • 00-20mph – indicating a slow serve; that’s okay, everybody has their off days.

The radar is behind the server not at the net.

The speed is calculated by the difference between the transmission frequency and the receiving frequency (known as the Doppler shift). So in a nutshell, the radars measure at least two times… one first moment to pinpoint and a second one (several ones actually) to calculate the distance went, and therefore the speed at which the object traveled.

  • Find out exactly how fast your shoot was.
  • The statistic that the tours could use to promote their players
  • Stopwatch. Very useful in practice.
  • More precise readings.
  • Just about as effective.

Radar is the ideal training tool and a radar gun for tennis. Dial in serve speeds to keep the opposition off balance, increase ground stroke power and provide instant, objective feedback to improve performance.

A tennis radar gun provides easy identification of your speed. The entire player will change their swing according to the speed of the ball. A radar gun for tennis is a straightforward and specific manner to test your power and compete along with friends.
