Field Notes
Notes from the sensor rig — plain explanations of how your wrists actually set, hold, and release the club, and what to do about it.
The Wrist Set Angle at the Top, Explained
What "hinge angle" actually measures at the top of the backswing, and why the number alone doesn't tell the whole story.
Read article →Radial vs. Ulnar Deviation: What the Terms Mean
The two wrist motions most golf instruction lumps together as "hinge," and why separating them changes how a fitting gets built.
Read article →Lag Pressure and Hinge Retention
How much hinge angle actually survives from the top into the downswing, and why "lag" is a retention problem more than a formation one.
Read article →Cocking the Club Early vs. Late
Two legitimate ways to form a hinge on the way back, and why fitting one style with the other's equipment causes problems.
Read article →The L-to-L Drill and Hinge Timing
What a classic swing drill actually teaches about hinge formation, and how we use sensor data to check if it's working.
Read article →How Grip Thickness Changes Hinge Feel
Why grip diameter shapes hinge formation more directly than most golfers assume, and how we test it during a fitting.

Reading about hinge mechanics is a start — seeing your own angle-over-time graph on the sensor rig is where it actually clicks.
