Well, now days almost everyone uses a radar gun. Bat speed technology now exists through a few devices and we used the Blast Technology to test bat speed, bat velocity, and other important metrics. We also use a radar gun to test bat exit velocity along with throwing overhand velocity and pitching velocity.
12. A steel ball rolls with constant velocity across a tabletop 0.950 m high. It rolls off and hits the ground 0.352 meters from the edge of the table. How fast was the ball rolling when it left the table? Answer: 0.800 m/s 13. A ball is launched with an initial velocity of 4.47 m/s at an angle of 66° above the horizontal.
I ran some simple linear regressions to see which, if any, normal baseball stats could possibly be predicted by the hitter’s exit velocity. I only used players with at least 100 at-bats and 50 or more exit velocity counts. It turns out that the stats most likely to be predicted by a player’s average exit velocity are indeed the power stats.
was compared to jet thrust derived from a Prandtl tube velocity distribution. Testcraft speed had been measured by a radar gun during the 1983 trial, but it required two test personnel at a fixed station. One person aimed the gun and reported speed readings to a second person who had to record the readings.

In the old days, before Pitch F/X, you could get readings on both. Technically you’d get a speed out of the hand from one type of radar gun and as it crossed the plate with another.
