Product Description
The Innovative Pitch Gauge – Purple (Interchangeable Thumb) is an extra‑large, color‑coded gauge engineered to measure pitch in modern interchangeable thumb systems. Designed for oversized thumb‑hole diameters used by VISE IT, Turbo Switch Grip and JoPo Grip thumbs, this purple gauge provides accurate readings of forward, reverse and lateral pitch in outer sleeves and interchangeable thumb holes.
Manufactured at Innovative Bowling’s Pennsylvania factory, the gauge features a scale graduated to 1/16", giving pro shop operators and advanced bowlers the fine resolution needed to verify or replicate precise pitches across multiple balls. Its XL size allows the gauge to fit comfortably into interchange thumb holes that are too large for standard thumb gauges, solving a common measurement challenge in modern fit systems.
Used alongside Innovative’s black standard thumb gauge and green finger gauge, or as part of the complete 3‑piece pitch gauge set, the purple interchangeable‑thumb gauge helps ensure that outer sleeves and drilled interchangeable holes match a bowler’s desired specs. This improves grip consistency, reduces surprises when swapping thumbs between balls, and supports more repeatable releases on the lanes.
Innovative Pitch Gauge Purple FAQ
What does the purple Innovative Pitch Gauge measure?
The purple gauge is extra‑large and color‑coded for interchangeable thumb holes. It measures forward, reverse, and side pitch in oversized outer sleeves and thumb holes used by systems like VISE IT, Turbo Switch Grip and JoPo Grip.
Why is a dedicated interchangeable thumb gauge needed?
Standard thumb pitch gauges are too small to fit common 1 1/2"‑style interchangeable thumb holes. The XL purple gauge is sized to fit these larger diameters, allowing accurate measurement of the actual hole pitch rather than only the removable inner thumb.
How precise is the purple pitch gauge?
The scale on the gauge is graduated to 1/16", providing fine resolution for small pitch adjustments and accurate replication of existing interchangeable thumb layouts.
Who typically uses the purple interchangeable thumb gauge?
Pro shop operators and advanced bowlers using VISE IT, Turbo Switch Grip, JoPo Grip or similar systems rely on this gauge to verify outer sleeve pitch and ensure that interchangeable thumbs feel consistent across different balls.
Can the purple gauge be used with standard thumb holes?
No. This specific model is sized for extra‑large interchangeable thumb holes. For conventional thumb holes, Innovative’s black standard thumb gauge is recommended; for finger holes, the green gauge is used.
Does the purple gauge come in a set?
Yes. Innovative offers a 3‑piece pitch gauge set that includes the black standard thumb gauge, green finger gauge, and purple interchangeable thumb gauge, providing complete pitch‑measurement coverage for all hole types in a bowler’s equipment.
