Some areas of the country do throw the weight in youth competitions. If you or one of your athletes is scheduled to throw in a youth meet, you will need to contact the meet director and check what size weight they will be using for the age group.
In the sense of performing as designed, most radar detectors do detect the presence of police radar in the immediate vicinity of a speeding vehicle. Whether or not that information will actually prevent a driver from receiving a speeding ticket remains to be seen, however.
Let's get down to the real how it works of a radar detector. When police use radar to detect speed, they cast a beam across the section of road they want to monitor. These beams are essentially a police broadcast across a band â either X, K, or super wide Ka bands. These radar bands, like AM or FM radio bands, vary in wave shape and frequency. X band is a short range radar wave.
