SIGHTRIGHT · BRIDGE-HAND CLEARANCE
How to Use SIGHTRIGHT When Your Bridge Hand Is on the Cushion
Check a rail-supported bridge as a stationary setup question without turning the trainer into part of the shot.

Short answer: first choose a safe, legal cue direction and your normal bridge form without SIGHTRIGHT. Then check whether the trainer, cushion, bridge hand, cue, body, clothing and balls can all remain clear. Use the device only for a short stationary standing-start, walk-in and still-address observation. Stand up and remove it before chalking, feathering, practice strokes or striking; bridge stability, cue elevation, contact, speed and outcome belong to normal practice.
Define the bridge-hand question
A bridge hand partly on a cushion or rail is a physical setup condition, not a universal technique. The hand may be supported by the cloth, rail top or cushion edge depending on the table and the shot. Your cue direction, bridge shape, grip, reach and comfort still need to be chosen with your ordinary cue-sports process.
The question for SIGHTRIGHT is narrower: after you select that direction, can you walk into a still address while the trainer has a stable, visible place away from the hand and cue? The device does not decide whether a rail bridge is legal, comfortable or technically best, and it cannot calculate contact or cushion response.
Keep this intent separate from the cue-ball-near-cushion check. That guide addresses the cue ball creating bridge and cue clearance limits. Here, the bridge hand itself is the layout constraint. If the cue must be raised, read the separate elevated-cue setup guide rather than combining two questions.
Check the rail, hand and cue corridor first
Before placing anything, stand back and trace the selected cue direction. Look at the rail, cushion nose, bridge-hand support, cue shaft, butt, sleeve and clothing. Include nearby balls and the space needed to walk in. SIGHTRIGHT must sit flat and stable; it must not touch the hand, cue, cushion, balls or clothing.
If the hand would cover the trainer, the cue would pass over it, or your body would have to twist to avoid it, stop. Do not balance the device on an edge, shorten the bridge solely to make it fit or move a ball without recording a new layout. “No safe space for a trainer check” is a useful conclusion.
For the curved notch, silver centre line and raised reference planes, follow the SIGHTRIGHT placement guide. Use only the product’s ordinary flat orientation and keep the table free of unnecessary objects.

Run a short stationary, no-hit observation
Choose one uncomplicated direction with enough room to approach normally. Place SIGHTRIGHT only after the direction and bridge form are fixed. Begin upright, walk in at your usual pace and settle at a still address before any feathering. Observe the reference, hand support and cue clearance without moving a ball.
- Start upright.Return to the same general starting area before every entry.
- Walk in normally.Keep your selected rail bridge and cue direction; do not chase a preferred label.
- Stop at address.Keep the cue still and check trainer, hand, cue, body, clothing and rail clearance.
- Record neutrally.Use left, centred, right or unclear, plus balance and bridge stability.
- Stand fully up.Repeat only after a complete reset and only while the setup remains safe.
Three to five entries are enough for a short block. Do not rotate SIGHTRIGHT or alter the hand while you are down. If it rocks, the cushion crowds it or your hand loses support, stop instead of forcing a conclusion. The full-reset guide explains why standing up between entries matters.

Compare one bridge variable only
After the unchanged baseline, you may compare one modest, comfortable alternative, such as a small change in hand support or bridge width. Keep the selected line, trainer placement, starting area and observation language stable. Do not combine a different cushion, cue elevation, spin or shot direction in the same block.
Use descriptive notes: hand feels stable or unstable, cue corridor clear or crowded, body balanced or strained. A label is not an instruction to move your head, twist your wrist or force the hand onto the rail. Stop for pain, loss of balance, restricted cue travel or visual discomfort.
A rest or mechanical bridge is a separate equipment question. Use the rest-shot setup guide when that support is part of the shot, and do not place SIGHTRIGHT where the rest head or shaft could contact it.
Remove the trainer before normal bridge practice
When the observation is complete, stand up and lift SIGHTRIGHT entirely from the playing area. Store it beyond the cue, bridge hand, balls and walking route. Confirm the cloth and cue path are clear before chalking, feathering, making practice strokes or striking.
Now practise the rail-supported bridge without the device. Check hand stability, cue elevation, tip contact, cue delivery, speed, cushion interaction and ball travel as separate factors. A clear stationary view does not validate the bridge or aim, and a miss does not explain which part of the shot changed.
Use the trainer-free transfer guide to keep normal cue-sports work larger than the visual block. Review the real images and confirmed specifications on the SIGHTRIGHT product page before planning another safe observation.
Keep the limits clear
Do not use the trainer as a rail bridge
SIGHTRIGHT is not a hand rest, target, obstacle or cue support. Keep your hand and cue in their own space.
Do not confuse the rail with the cue ball
If the cue ball is the source of the crowding, use the separate cue-ball-near-cushion process rather than rewriting this bridge-hand observation.
Do not turn an unclear view into a vision claim
Check position, light, contrast and comfort. SIGHTRIGHT is not medical equipment, an eyesight test or an accuracy guarantee.
Bridge-hand-on-cushion FAQ
Can I place SIGHTRIGHT beside a bridge hand that rests on the cushion?
Only if the trainer can sit flat and stable with clear space around the rail, hand, cue, body, clothing and balls. If any part would crowd or touch the setup, do not force the device into the layout; use a safe open recreation of the selected direction instead.
Does SIGHTRIGHT tell me how to form a rail bridge?
No. Choose a legal, comfortable bridge form yourself. SIGHTRIGHT can provide a short stationary setup reference, but bridge stability, cue elevation, tip contact and delivery must be practised separately after removal.
Is this the same as checking when the cue ball is near a cushion?
No. This guide focuses on the bridge hand being partly supported by a cushion or rail. A cue ball near a cushion creates its own cue and bridge-clearance question; use the separate cue-ball-near-cushion guide for that layout.
Can I feather or strike while SIGHTRIGHT is in place?
No. Complete the standing-start, walk-in and still-address observation, then stand up and remove the trainer completely before chalking, feathering, practice strokes or striking.
