How to Use SIGHTRIGHT When Your Bridge Must Clear Another Ball

Separate the ball problem from the visual question

An interfering ball can sit in front of the bridge, beside the shaft, or under the line your forearm would normally occupy. These are different spatial problems even when the shot name is the same. First use the rules and your own table reading to choose the legal target, first cue-ball direction and intended outcome. SIGHTRIGHT should enter only after that decision exists.

Write a one-line brief such as “bridge hand passes to the left of the blocker; cue travels above it; no rail contact.” That brief is a planning record, not an instruction supplied by the device. SIGHTRIGHT’s aluminium body, centre line and reference planes can help you describe a selected setup; they do not calculate contact, select an aim or rule on a shot.

Do not fold a rail-supported hand into this experiment. The cushion-bridge guide deals with support from the table edge. If the blocker forces a raised cue, keep that separate and consult the elevated-cue guide.

Build a clearance map around the blocker

Leave the balls exactly where they are and inspect the layout from above and from the player’s entry side. Imagine a narrow vertical plane through the bridge hand and a horizontal tunnel through the cue shaft. Add a third boundary for the butt, sleeve and torso. SIGHTRIGHT needs its own patch of flat cloth outside all three boundaries.

1. Mark the hand zone.Note where the bridge fingers or heel would sit, including any lift needed to clear the blocker.
2. Mark the shaft tunnel.Trace the cue’s intended height and angle without making a stroke.
3. Mark body access.Leave a route for the walk-in, withdrawal and a safe rise.
4. Reject forced placement.If the device would touch a ball, cloth edge, hand, clothing or cue, use a surrogate layout instead.

For documented product images, visit the SIGHTRIGHT product page or cue-sports supplies. Never wedge the trainer against a second ball to keep it still.

Observe the chosen setup without a hit

Place SIGHTRIGHT in the mapped patch, then begin from your normal standing viewpoint. Walk into the address you intend to use and pause before the cue moves. Check four relationships: the hand clears the blocker, the shaft clears it at the chosen height, the body stays balanced, and the trainer remains untouched.

Make independent entries rather than sliding into the next one. After each entry, jot a short spatial note—“upper edge clear,” “knuckle crowded,” “butt path open,” or “trainer too close.” This vocabulary is deliberately different from a verdict about correctness. If the view changes, inspect the map, lighting and placement before changing your bridge.

Stop immediately if a ball rolls, the hand loses its support, clothing catches, or the device shifts. The observation has answered its question: the proposed corridor needs a safer arrangement.

Use an open-space surrogate when the real position is too tight

A surrogate preserves the selected first direction while removing the dangerous crowding. Move to an open part of the table, or rebuild a simple cue-ball line with a spare marker placed well away from the trainer. Keep the direction, approximate cue height and bridge side; do not pretend the rail, blocker distance or body access are unchanged.

Record the differences explicitly: “surrogate removes vertical obstruction,” “rail support absent,” or “cue elevation not reproduced.” That note prevents an open observation from being mistaken for a full simulation. It can still show whether your chosen entry and reference remain intelligible before you return to the original layout.

If the shot needs a mechanical rest, use the rest-shot setup guide instead. A rest head is equipment with its own clearance map, not a substitute for a ball.

Clear the table, then practise the actual stroke

Finish the final still observation, stand clear and remove SIGHTRIGHT from the cloth. Put it beyond the cue route and ball path. Only then chalk, feather, take practice strokes, move the cue or strike.

With the trainer gone, assess the bridge-over-ball shot on its own terms: hand stability, cue elevation, tip contact, speed, cushion response and ball travel. A tidy clearance map cannot validate the aim or delivery, and a miss cannot tell you which physical variable changed.

The trainer-free transfer guide helps keep ordinary practice larger than the reference exercise. Return to the product record at SIGHTRIGHT when you plan another controlled session.

Know what this experiment cannot establish

The blocker is not a measuring jig

Another ball provides the physical constraint; it is not a rest for the trainer, cue or hand. Keep every object supported by its intended surface.

A clear tunnel is not a prescribed technique

Your notes can say “fits” or “crowds,” but they cannot dictate a universal bridge height, head location, wrist angle or cue elevation.

A visual note is not a health or result claim

Lighting, contrast and comfort can affect what you notice. SIGHTRIGHT is not a medical device, eyesight test, rules authority or promise of accuracy.
