Every Bowler, one tap away

Search your Bowlers by name and open anyone's Fit, Release and every ball you've drilled for them.

A Bowler's record

Their current Fit and Release in one place: spans, hole sizes and pitches, PAP, axis tilt and rotation, speed in km/h or mph, and rev rate.

Every ball drilled

Each ball keeps the Layout, Fit and Release it was drilled to. Retired balls stay in the Bowler's history.

Layout calculator

Enter a Layout in dual angle or VLS, or in 2LS for a ball with no thumb hole. You get the pin, CG and PSA positions measured from the centre of grip, with a diagram to check by eye.

Why Driller's Book

Drill sheets pile up, fade and get lost under the press. Driller's Book replaces the stack with one record per Bowler, there whenever they walk back in.
