Here's a radar unit that fits in your pocket. Guess that's why it's called Pocket Radar!

How fast is your kid’s fastball? How fast is your favorite car going at that NASCAR event you’re at? How fast did the neighbor’s kid drive past your house?  It’s easy to find out with Pocket Radar. It’s about the size of a pack of playing cards, but this device utilizes a Doppler radar signal detection and processing system coupled with re-engineered microwave and antenna components to deliver the same powerful performance of traditional bulky radar guns! Designed to be used by both professionals and everyday consumers in a wide range of applications, from coaches clocking baseball pitch speeds, to athletes seeking improved performance, Pocket Radar forges a new standard in speed radar performance. Accurate to within 1 mile per hour, Pocket Radar is able to take 10,000 speed measurements using one set of AAA batteries. Its small size and easy-to-use point-and-shoot functionality means that Pocket Radar users can get right to the action, while others are still setting up and turning on their traditional, bulky radar speed guns. $249.99 But there is an introductory offer if you pre-order at the company’s website. You pay $199.99, so you’ll save $50.
