For years, I trusted that the sanding pads, compounds, and polishes used produced the labeled grit. Laser scanners were available, but were bulky and expensive. The adaptation of a handheld glossmeter to bowling ball surfaces is pure genius. I love the affordability, portablity, and most of all being able to check and recheck the results as needed. This is a game changer for bowling. Thank you, Ron Hickland and CTD.
