Speed gun
The Speed Gun is used to measure the speed of the ball from one end of the pitch to the other. The technology allows calculating the speed of bowler’s delivery. Implemented first in 1999, the speed guns gets mounted on a pole and positioned next to the sight screen. The device relays a beam from the radar head movement across the entire length of the pitch.
This technology actually tells us what is the speed of a delivery and what the highest speed the player achieved while setting up the record.
