not made for rc cars

the manual does not tell about all the ports that are available on the device, there is nothing describing calibration; need of or tools to do, have moved it around and still not sure where is the best spot, behind the catcher or behind the pitcher ...

This product was a total disappointment. We tried to use it to track how fast our team could shoot the puck. This product did not work as advertised. Read shots inaccurately, picked up the stick hitting ground continuously at 64 mph. We did find out that we could whistle at 199 mph. Avoid this radar!!!!

It works great, gives accurate and quick readings. Some problems I noticed were it doesn't seem to work in direct sunlight. I don't know if it was the sun, or the unit got too hot, but on summer day, it doesn't work. Also, it's hard to tell if the unit is actually turned off/on, so if it's not working you can't tell if it's dead batteries, or just turned off, this can be frustrating. Also, you can't use rechargable batteris, why?

I'm a coach who also bought this for my little league team. It has provided consistently accurate speed readings and has been very useful in helping my team improve their throws and confidence.
