How to Position SIGHTRIGHT: Curved Notch, Centre Line and Reference Planes

Know the three SIGHTRIGHT placement references

SIGHTRIGHT is an aluminium-alloy training accessory measuring 150 × 23 × 18 mm. Its shape gives you three practical references: the curved front notch, the silver centre line and the two-level structure that creates front and rear visual planes.

None of these parts calculates the correct potting line. The player still reads the shot and selects the intended direction. The trainer makes that existing direction easier to preserve while moving from the standing view into the address position.

Set the line before positioning the trainer

Begin with a simple, familiar layout. Stand behind the cue ball and read the shot as you normally would. Decide the intended cue-ball direction before placing SIGHTRIGHT. If you rotate the tool until the view looks convenient, the tool is choosing the exercise instead of preserving your original decision.

Keep the cue ball still. If the venue allows removable position markers, they can help you rebuild the same setup without damaging the cloth. Otherwise, use fixed table features or an overhead reference photograph. Clean, dry hands also reduce the chance of moving the aluminium tool as you release it.

Use SIGHTRIGHT only as a stationary visual reference. Do not strike the cue ball while the trainer remains in the playing area.

How to position SIGHTRIGHT step by step

1. Select the cue-ball direction.Finish the standing read first and keep that direction in mind.
2. Approach from above.Lower the trainer onto the cloth without sliding it into the cue ball.
3. Place the curved notch near the ball.Use the notch to establish the front relationship while leaving the cue ball undisturbed.
4. Point the silver centre line.Rotate the trainer so the centre reference follows the intended direction rather than the edge of the table or another unrelated feature.
5. Check the full length.Look from above and confirm the rear of the trainer has not swung away from the selected line.
6. Release without nudging it.Lift your fingers vertically and recheck both the ball relationship and direction.
7. Return to the same standing view.Start every observation from the same comfortable area behind the shot.

How to use the two visual planes

Once the trainer is fixed, look from your standing position and note the relationship between the front and rear references. Walk into the shot using your normal rhythm, settle comfortably and inspect the same references again before feathering the cue.

Use a neutral observation label such as left, centred, right or unclear. The label describes what you see in that setup; it is not a medical result and it does not prove why a later shot is potted or missed.

Stand up fully between checks. If the view changes, confirm that SIGHTRIGHT and the cue ball are still in the original positions before changing feet, head position or approach. The trainer cannot be a stable reference if it moves at the same time as the player.

Troubleshoot a SIGHTRIGHT placement that keeps changing

The centre line points in a new direction

Recheck the entire trainer from above. A small rotation at the front changes the rear direction. Reset it to the line you selected rather than adjusting your stance to match the new angle.

The notch-to-ball gap changes

Confirm that the cue ball has not rolled and that you are lowering the trainer instead of pushing it across the cloth. Rebuild the front relationship before making another observation.

The view changes before you walk in

Your standing location or head height may be different. Return to the same comfortable starting area and use the same upright viewing routine. Do not force the body into a painful position merely to copy one picture.

The placement looks different in a phone image

A phone held at a different height or angle can change the photograph. Treat a picture as a setup record only when the camera position is also consistent; do not use an angled image as proof of the playing view.

Make the placement repeatable between sessions

Record the chosen layout, the cue-ball relationship, the direction reference and the standing start point. One overhead photograph can be useful when it shows the complete trainer and table landmarks. Keep the trainer orientation obvious rather than cropping to the front notch alone.

Before a new practice block, place SIGHTRIGHT twice from scratch and compare the result. If the two placements differ, improve the setup reference before collecting stance observations. This keeps tool placement error separate from player movement.

For the complete practice sequence after placement, read how to use a sight alignment trainer. If the tool stays fixed and you want to investigate a repeatable left-centred-right pattern, continue with the snooker stance and sight-line check.

Common SIGHTRIGHT positioning mistakes

Changing the selected line to fit the tool

Read the shot first. SIGHTRIGHT preserves that decision; it does not supply a new potting line.

Checking only the curved notch

The front can appear correctly placed while the rear is rotated. Confirm the full centre-line direction.

Moving the trainer after every view

A moving reference cannot show whether your repeated approach changed.

Letting the cue ball move during placement

Lower the trainer carefully and reset the layout if the ball is nudged.

Interpreting the planes as a medical test

SIGHTRIGHT is not a medical or vision-correction device and cannot diagnose eyesight.
