ST3 featuresTracking
The hit on the screen is the hit you made
Optical tracking on Marksman ST3 measures where your firearm is pointing and maps the shot onto the projected screen. Precision is 0.18 MOA, about 5 mm at 100 m. A laser spot on the wall is a different method, and a beam that spreads by degrees cannot show a miss of a few centimetres.

What you can train
- 01
Aim
Mount and aim are measured on the firearm, not inferred from a spot on the wall.
- 02
Lead
A moving target stays readable because the track keeps up with the swing.
- 03
One correction
Change your feet or your hold. The next shot uses the same track, so you can see what moved.
What you see
- 01
A small miss stays small
You can trust a miss of a few centimetres. That is the difference between a correction and a guess.
- 02
ST-2 was the previous step
ST-2 tracked at about 1 MOA on a cable. ST3 is wireless at 0.18 MOA.
Realism, safety, ethics
If the track is wrong, you practice the wrong correction. The precision is what makes the lesson carry outside.
Questions
How accurate is Marksman ST3 optical tracking?
Marksman ST3 tracks the firearm at 0.18 MOA, about 5 mm at 100 m. The previous ST-2 tracker was about 1 MOA and wired. ST3 is wireless.
How does ST3 tracking compare with a laser simulator?
Typical laser simulators are limited by beam spread to about 2°, roughly 120 MOA. ST3 at 0.18 MOA is about 650 times more precise than that class, before ballistics or the firearm itself.
What is the Marksman ST3 shooting simulator?
Marksman ST3 is a projector-based shooting simulator for your own rifle, shotgun, or handgun. A wireless optical tracker maps each shot to the screen at 0.18 MOA, about 5 mm at 100 m, with about 1 ms from shot to picture. It is not a laser insert, a VR headset, or a game controller, and no live round is fired at the screen. The previous ST-2 tracker was about 1 MOA and wired.
The rest of the system
Figures are published Marksman ST3 specifications: 0.18 MOA tracking, about 1 ms from shot to screen, 235 calibers, 4,700+ rifle and handgun profiles, and 12,600 shotgun combinations.
