A batter hitting a baseballThere are four basic skills required in baseball: hitting the ball, catching it, throwing it, and running all over the place. Among all of these, it is throwing the ball that is most crucial in defense.

The pitch

Baseball is built on the pitch. This is where the game begins. Kids start out knowing only one pitch, the fastball. They try to throw as hard and as fast as they can. Players learn other types of pitches as they play the game. At some point, a player would settle to be the catcher, and someone else is noticed as the best pitcher on the team. That is the dynamics of learning to play in a game. From learning how to throw, then getting stronger with the throw, the pitcher then learns other pitches, including the curveball. A pitcher needs both speed and versatility in order to defeat a hitter.

A spectator’s tool

For spectators, a radar gun for baseball is one of the best tools they can bring along with them when watching a game. This is an easy-to-use tool, which can give the speed of the baseball during a pitch. The radar gun is pointed at a distance of one foot away from the release. This is usually an approximate direction, but there is no way to point to the exact direction of throw properly. Although not everyone has a radar gun, it can be a fun tool to use in amateur games. It can even be used for other sports where the ball’s speed is key.

Doppler shift

Radar guns work on the Doppler shift of an electromagnetic pulse. The gun emits a microwave beam. Shot in the general direction of the ball, the beam bounces back and this return is calculated for the speed, according to the difference in frequency. It may take a while to get used to, but it is important that reading a ball’s speed is done properly.
