Calipers Meaning in Lawn Bowls

Calipers serve as a precision measuring tool used by the game umpires. These metal instruments determine which bowl sits closer to the target jack. Umpires use them when the distance is too small for the eyes. The tool features two adjustable arms that lock into a specific width. Using calipers ensures a fair and accurate score for every single round. An official places one tip on the jack and one on the bowl. This measurement proves that the red bowl is closer by two millimeters. Accurate readings prevent arguments between competing teams during very high stakes matches. Every club house keeps several sets of calipers for official league play.
