Purpose: The rocker arm (orange) design eliminates any target ball movement when measuring. It is repeatably accurate to 5-6 thousands of an inch (less than 2 hair widths!!) and due to the "no load lever" will not push a ball away even on a smooth surface.
The Accu-Arm method of measuring is to transfer the target ball readings to the top of the measure where it is easiest to read.
This device can handle target balls from 1" to 2.5" which is the complete range for, Petanque, Bocce and Lawn Bowls.
