Club Tracer Worker Portal

1. Club head: click the centre of the club head. 2. Shaft line: place a two-point line only along the visible shaft, from where the golfer's hands meet the club to the last clearly visible point on the shaft. Do not snap it to the club-head dot. 3. Blur: drag a box when too blurred, then optionally swivel it. Once a blur box exists, drag it or its edges to adjust it. 4. Not visible: mark if neither a centre point nor blur box is reliable. 5. Remove: keep the image out of training.

7. Ball: only when the ball is clearly sitting on the ground at address, click its centre. 8. Partial ball: use when the club or hands hide most of the ball and only part of it shows. The ball is optional — if there is no ball on the ground, just leave it unmarked and move on. It never blocks moving to the next image.

Use zoom when you need to inspect the club head closely. When zoomed in, scroll the image area to pan around the frame before placing labels.
