Here's a low-cost radar (under $200!) from Pocket Radar that you can use in all sorts of sporting applications... baseball pitching speed, tennis service, speed, motorsports... Why spend thousands of dollars on an big and bulky old-tech radar gun? And this baby is aptly named, it will literally fit in your shirt pocket.
An old college friend is an engineer with the company that developed this high-tech gadget.
So, if you want to measure just how much smoke your star pitcher is hurling, grab one of these.
