Avoid touching the jack while you measure without strings, springs or finger-snapping recoil! The Impulse laser measure is the modern, fast way to determine the scoring bowls. It can be used officially by bowlers in place of the classic string measure. Long measures can be made by a single bowler without needing a second bowler on the other end of the string. Plus the Impulse stores the shot measurements on its LCD screen so everyone can see and audit them.
