Golf Fit Toolkit
Six fitting checks in the order that matters: length changes everything after it, gapping proves the whole bag. Each result tells you what to verify next.
Club Length Calculator
A static starting estimate from height and wrist-to-floor, with a practical trial range and a verification checklist.
Lie Angle Check
Read sole marks and start lines to tell whether your irons play too upright or too flat, without guessing degrees.
Grip Size Finder
A starting grip size from a hand measurement, with a glove-size fallback and the dynamic check that confirms it.
Shaft Flex Calculator
A flex shortlist from swing speed or carry, adjusted for tempo and release, with the reasons spelled out.
Swing Weight Calculator
Measure swing weight from total weight and balance point, and estimate what a component change will do.

Enter carry distances, see every gap and overlap, and keep the map on this device.
