How to Use SIGHTRIGHT for an English Billiards Cannon Setup Check

Define the cannon question before the trainer enters

A cannon in English billiards asks the cue ball to contact both object balls. That makes the playing problem more complex than a single-pocket setup, but SIGHTRIGHT should not be asked to solve the complexity. Decide the intended first contact, broad cue-ball route and safe practice direction using your ordinary knowledge of the table and the rules or coaching source you trust.

For this SIGHTRIGHT English billiards cannon setup check, keep one question narrow: does your physical standing start and walk-in remain repeatable while you look at the first cue-ball direction you already selected? The trainer cannot validate the first object-ball contact, rebound, throw, pace, side, cushion response or the second contact. Those belong to a separate, trainer-free playing record.

If you also practise pool, the English pool alignment guide explains why the discipline and layout should be named in your notes instead of treating every cue-sports table as identical.

Prepare a simple, open cannon layout

Start with a familiar arrangement that leaves room for the device, bridge hand, cue, clothing and a natural route around the table. Do not begin with a crowded cluster, cushion-supported bridge or extreme reach; those constraints can hide the setup question before a baseline exists.

1. Choose the intention.Write the first contact, broad cue-ball direction and cannon idea without using SIGHTRIGHT to discover them.
2. Keep positions fixed.Use the same cue-ball and object-ball locations for the full observation block.
3. Check the space.Confirm that the trainer, cue and bridge can stay clear of every ball and cushion.
4. Place the reference.Set SIGHTRIGHT gently along the already selected first-direction line.

Use the reference-plane guide for the curved notch, centre line and raised visual planes. Never force the trainer against a ball or change your normal bridge simply to make it fit. If the table is crowded, recreate the selected direction in open space or end the check.

Run a stationary, no-hit observation

For each pass, return to one ordinary upright starting mark. Glance along the chosen first direction, enter the stance as usual and freeze at address before the forearm or cue begins to move. Read the device only in that quiet moment, with every ball still. Rise completely, make the note and begin the following pass from standing.

1. Keep the entry familiar.Avoid curving, narrowing or stretching the approach merely to obtain a particular visual result.
2. Freeze before cue action.Check space for the bridge, cue and body before any chalk or feathering appears.
3. Write a neutral result.Choose left, centre, right or unclear, then note comfort, balance and physical clearance separately.
4. Leave the stance each time.Step back to the upright start so one observation does not flow into the next.
5. Keep the sample small.Three to five independent entries give enough evidence for this comparison.

Treat the series solely as a record of this cannon arrangement on this day. It cannot identify an eyesight condition, dictate where the head belongs or certify the selected route. End the exercise for discomfort, unsteadiness, a disturbed view or any loss of free cue space. The product does not test or treat vision.

Keep the two contacts out of the setup label

English billiards rewards careful separation of evidence. A stable walk-in does not tell you whether the first object-ball contact was correct. A correct first contact does not tell you whether speed, side, cloth or a cushion changed the route before the second contact. Write those as different fields.

This format prevents a successful or missed cannon from being turned into a visual diagnosis. If you change the selected first contact, cue, distance or spin intention, start a new record rather than averaging unlike trials.

Remove SIGHTRIGHT and test the complete cannon

Once the last stationary entry is recorded, come out of the stance and take SIGHTRIGHT off the cloth. Put it beyond all expected ball routes, walking lanes and cue space. Chalking and every form of cue rehearsal begin only after that clearance check; no moving cue or ball should approach the device.

Play a small trainer-free set with the same arrangement. Record delivery, intended first contact, cue-ball route, pace, spin, cushion response, second contact and score separately. A centred setup label cannot guarantee a cannon, while an unsuccessful attempt cannot single out setup alignment as its explanation.

Finish with a modest note such as “three full-reset walk-ins; first direction stable; bridge clear; trainer removed; four cannon trials recorded by contact and route.” For current product photographs, see the SIGHTRIGHT product page.
