Remove golfer shadows without moving the hitting zone blindly

Map the shadow before changing anything

A shadow means something interrupts the light travelling from the lens to the screen. Note whether it appears at address, during the backswing, through impact or only in the follow-through. Test right- and left-handed positions if the bay serves both. A location that works for one golfer can obstruct another.

With no balls in play, photograph the lens position, the hitting position and the screen from the side. Mark the approximate beam boundary and the full swing envelope on a room sketch. This is often more informative than the projector’s ceiling height alone.

Check the competing constraints

• Image size: a new mounting point must still fall inside the lens’s documented placement range.
• Swing clearance: check the full projector body, mount and cables, not only its lens.
• Launch-monitor geometry: an overhead unit may require a precise position relative to the ball; a rear radar unit needs its own clear measurement path.
• Screen containment: moving the golfer closer to the screen can increase bounce-back risk or put mishits outside side protection.

Work through reversible changes first

Remove an unnecessary object from the beam and confirm that it caused the shadow. Check whether the current image is needlessly larger than the intended screen opening. Where supported, optical zoom or lens shift may offer useful adjustment without relocating every component.

If a physical move is still necessary, recalculate the lens distance using the actual model and aspect ratio. Test the proposed position before drilling. A floor enclosure is an installation option only when it fits the projector, protects it appropriately, maintains ventilation and stays clear of feet, clubs and balls.

Verify the whole bay

After a move, recheck focus and image edges, all intended golfer positions, the launch monitor’s ball zone and the screen’s clearances. If the hitting position changes, revisit the launch monitor’s installation and calibration instructions rather than assuming the old settings remain valid.

For a room-fit question, send us a side-view photo and four measurements: screen width, finished floor-to-ceiling height, ball-to-screen distance and lens-to-screen distance. Add the projector and launch-monitor models. That lets the conversation start with the actual geometry.
