摘要:
A ball distance measuring system incorporates a support received over a reference ball. A reference on the support has a diameter differing from a diameter of the reference ball by a predetermined amount visually distinguishable from a circumference of the reference ball presenting an even visual separation confirming concentric coincidence when centered with respect to the reference ball.

摘要:
A laser distance comparator incorporates a case housing a laser controller for producing a laser beam. The case has a handle and a button for engagement of a positioning device over a reference ball. A switch control is present on the case for activating the laser controller and a central processing unit (CPU) receives an input from the switch control, providing outputs to the laser controller to obtain a distance measurement to at least one competition ball.
