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

seems to work fine. Maybe not as accurate as a real gun, but it is something!

Price is reasonable. I found that it is best for measuring the speed of your serves. It has pretty good reliability, the audio is hard to hear and it would be great if it had a Bluetooth capability so you can hear the speed, but it’s not broadcast all over the court. it doesn’t default miles per hour which I would prefer. When I try to measure my forehead while hitting with the ball machine, it’s not very useful because it needs a 4 second delay in between shots. It does help me cross reference from my phone app that measures all speed with a different technology .

This product is a very cool idea. It's easy to read...it just does not accurately measure the speed of a pitched baseball. It was off by ~8 mph on average vs radar gun. I wish it worked....but it doesn't.

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.

I was hesitant to make the purchase because there were so few reviews. So after I got it and tried it out I figured I'd write one. Works just as shown in the video. As someone else pointed out, to get your ball speed right off the racquet you should convert your speeds a bit due to the deceleration of the ball by the time it gets to the net. But still it works just fine and is a fair price for what you get.

Unlike the ones with the tuning forks at least this one actually works....Numbers are hard to see in sunlight and voice can seem muffled at times but hey after sending back 2 of its competitor I can't complain at least it works don't know how accurate it is however

The biggest thing I was worried about was consistency. I don’t mind if the accuracy off a little, I just wanted to make sure that all my tennis serves were around the same and that the radar didn’t give me a weird number.To my surprise this Radar Coach is extremely consistent! Most my first serves fell between 88-92mph with the fastest being 95mph. This is using used tennis balls. I think that with brand new balls I should be at around 100mph which I think is very accurate. I was worried buying this seeing only one 1 star review, but I’m really glad I bought it. Definitely recommend!

Not accurate. Seems about 20 mph off.
