Accelerator is the stage that rewards planning more than shooting. Two targets close on the left, two far on the right, and a stop plate on the center line between them. It looks scattered. It is actually two clean pairs and one obvious finish, and once you see it that way the stage gets a lot faster.
One 10-inch plate, one 12-inch plate, two 18″×24″ rectangles and one 12-inch stop plate. One 3′×3′ box. Five strings, best four counted.
Our own scale plan of SC-105 · Accelerator, drawn from the dimensions published in Appendix B of the SCSA Competition Rules, edition 2026-03. Seen from above, shooting box at the left — the near pair sits low-left, the far pair high-right.
| Target | Size | Distance from the box | Offset from center | Height to top |
|---|---|---|---|---|
| Round plate | 10 or 12 inches | 30 ft | 12 ft left | 5 ft |
| 18″×24″ rectangle | 18 x 24 inches | 30 ft | 4 ft left | 5 ft 6 in |
| Round plate | 10 or 12 inches | 60 ft | 6 ft right | 5 ft |
| 18″×24″ rectangle | 18 x 24 inches | 60 ft | 20 ft right | 5 ft 6 in |
| 12″ stop plate | 12 inches | 45 ft | on the center line | 5 ft |
The rulebook diagram specifies one 10-inch and one 12-inch round plate but does not label which position gets which, so we have not guessed. Check the stage as it is set at your range.
The stage peak is the aggregate of your 4 counted strings. Divide it by 4 and you get a par time you can set on a shot timer today.

Peak times verified against SCSA’s live classification system on September 8, 2026. The full 16-division table is on our peak times page.
The left pair is at 30 feet: a rectangle 4 feet off center and a round plate 12 feet off center. Both are close and both are easy. The right pair is at 60 feet: a round plate 6 feet off center and a rectangle 20 feet off center — the widest target on the stage, and twice as far away as the left pair.
The stop plate splits the difference at 45 feet on the center line. That geometry is what the stage name is about: the run accelerates, or it should. Easy and close first, hard and far second, then a short move back to the middle.

Peak times from SCSA’s live classification system, retrieved September 8, 2026. The diagram above is our own drawing made from the published dimensions. If a measurement here does not match the stage as your club sets it, the rulebook and your match director are the authority — and we would like to know about it.
The date under the headline is the last time we checked this page against its sources — not the day it was first written. Rulebooks get amended, regulations change and season dates move, so we review these guides on a regular cycle and re-stamp the date whenever we revise one. If you find something here that has changed before we caught it, email [email protected] or tell us at the counter; we will verify it against the source and correct it.
We write these because people ask us at the counter. Everything in them we either sell, service, or shoot ourselves — and if you'd rather talk it through than read about it, come in.
