[QUOTE="Susquatch, post: 1655382, member: 31264"] The LabRadar does not need bullet info like that because it measures velocity directly. Muzzle brakes do affect optimum positioning of the LabRadar. It's best to think about the process differently. A radar system bounces microwave pulses off the base of the bullet as it speeds away and detects the dopler frequency shift to define the velocity. The accuracy of that signal improves as distance increases due to the Cosign Law, but the signal strength goes down as the bullet gets further away. Leaving the radar on to detect shots consumes a lot of battery power. So the unit CAN use the sound blast to turn the radar on. Very roughly, the speed of sound is a thousand fps. So when the sound reaches the unit, the bullet is about three times further away. A large bullet might only be 2x away. Signal strength for large bullets is much greater. Muzzle brakes increase the sound energy and can also "jiggle" the LabRadar. So the unit should be moved rearward a few inches. It's never been a problem for me. I believe that there are some FAQs on the LabRadar website. [/QUOTE]
