Product Description
The Innovative Span Gauge with 1‑1/2" Stud is a precision span‑measuring tool designed for drillers who prefer a larger stud footprint on the bowling ball. Manufactured at Innovative Bowling’s Pennsylvania factory, this gauge features a scale graduated to 1/16", allowing you to read span measurements in fine increments when fitting or duplicating grips for serious bowlers.
The 1‑1/2" stud is sized to fit securely into matching reference holes or plugs, giving the gauge a stable anchor point and allowing it to follow the ball’s curvature accurately as you align the grip centerline. This larger stud can offer added stability on certain layouts or training balls, making it easier to transfer spans from an existing ball to a new drill, check spans after plug work, or verify span symmetry for two‑handed or high‑rev bowlers.
Used alongside pitch gauges, automatic span gauges, and layout tools, the Innovative Span Gauge with 1‑1/2" Stud helps pro shop operators deliver more precise fits, improve comfort, and support repeatable releases. Combined with the 1" stud model and the automatic span gauge line, it becomes part of a complete measurement system for modern drilling and fitting workflows.
Innovative Span Gauge with 1‑1/2" Stud FAQ
What does the Innovative Span Gauge with 1‑1/2" Stud measure?
This span gauge measures bowling ball span—the distance between the thumb and finger holes—using a scale graduated to 1/16". It’s designed to give drillers precise span readings when fitting or duplicating grips.
Why choose the 1‑1/2" stud version?
The 1‑1/2" stud provides a larger anchor point on the ball, which can offer added stability when the gauge is seated in a reference hole or plug. Some drillers prefer this larger stud for certain layouts or balls used specifically for measuring and training.
How is the 1‑1/2" stud used on the ball?
The stud fits into a matching 1‑1/2" reference hole or plug, anchoring the gauge so it follows the ball’s curvature. Once anchored, you align the gauge with the grip centerline and use the graduated scale to read and mark spans accurately.
Why is precise span measurement important?
Span directly affects grip pressure, comfort, and release timing. Accurate span measurements help ensure the bowler’s hand sits naturally in the ball, reducing strain and promoting more consistent, repeatable shots.
Who typically uses the Innovative Span Gauge with 1‑1/2" Stud?
Pro shop operators, coaches, and advanced bowlers use span gauges when drilling new equipment, copying grips from existing balls, and troubleshooting fit issues. The 1‑1/2" stud version is a preference choice for shops that like the feel and stability of a larger stud.
How does this span gauge fit into a complete fitting toolkit?
The span gauge works in tandem with pitch gauges, automatic span gauges, grip charts, and layout tools. Together, these tools let drillers control span, pitch, and hole placement for a fully customized fit tailored to each bowler’s hand and release style.
