Innovative Bowling is pleased to announce a new, affordable, and highly functional measuring ball to compliment it’s fine line of Pro Shop Products. Innovative’s new Measuring Ball is unequaled when it comes to simplicity and accuracy. The span is measured by placing the thumb in a spring-loaded cavity and placing the hand over a span grid. On the other side of the grid is another spring-loaded cavity, which measures the angle of the thumb oval. Around the diameter of the ball is a complete range of 40 finger and thumb hole sizes. Spring mechanism pushes thumb to the front edge of the thumb cavity for edge to edge measurement. Span measurement to 1/16th of an inch. Custom plastic molded span grid is laminated onto the surface of the ball. Made from sturdy and attractive reactive resin bowling ball cover stock. Ball has a special hollow core so that the holes don’t meet under the surface. High quality bowling ball finish for an unmatched professional look. Another precision engineered product from Innovative Bowling Products.
