Sports Radar Coach – Measure Ball Speed for Tennis, Pickleball – Portable

I got this to practice Tennis Serves all by my lonesome. Some other guns require another person to hold it to clock your speed. This one is large, and bright so you can place it behind the net, and see it from the service line. It will also say your speed out loud. Two things you need to be aware of, is when you turn it on, it often defaults to KPH instead of MPH. So when you serve a ball and 105 comes up, you could get excited, but that’s really just in KPH, that’s only 65 MPH. The other is that this is measuring the speed when the ball travels over the net. Professional Tennis matches measure the speed right as the ball leaves the racket, and there is a HUGE dropoff as tennis balls lose speed quickly. A 120MPH serve off the racket, will be just 82MPH when it bounces. So I bet this radar would clock that ball at the net, of about 90MPH. So you have to make an adjustment.Radar Ball Speed off Racket90 12085 11277 10070 9061 75But this works well, and people love it when they try to serve faster and faster. Seems very accurate to me.
