Marksman ST3 vs TrueClays

No. Marksman publishes 1 ms from the shot to the screen. TrueClays publishes 4.2 ms as the spacing of each recorded barrel sample, on the tracker page and the features page. It is the time resolution of that trace, not a measured shot-to-screen delay.

TrueClays' setup guide uses a skeet clay at 25 m/s and says 1 ms of travel is 2.5 cm. At that speed, 4.2 ms is 10.5 cm. An ISSF clay is 110 mm, so 1 ms is about a fifth of the clay and 4.2 ms is almost the whole clay. At station 4 that is about 4.5 MOA against about 19 MOA.

On a straight bird, almost not. The delay runs along the bead, so the angle does not change. On a hard 45° Olympic trap bird the cross-track shift is about 7 mm in 1 ms and about 28 mm in 4.2 ms. Crossing skeet is the presentation that makes the clock matter.

TrueClays states laser detection at 0.1 pixel, often 0.01 pixel, on a 1920-pixel image. That is where the camera places the laser spot. The screen itself is entered in centimetres, and gun alignment is one point or three points, repeated if the test target is off. TrueClays also says a surface that moves a fraction of an inch makes the calibration invalid. Marksman holds the screen map at 0.1 pixel, the same result each time, with subpixel image processing.

The setup guide says 94% is the default, and Advanced Reaction slows the first metres further, because a 240 Hz projector is still a series of frames and shooters otherwise break the target later than on the range. Perceived Lead then shifts the picture by up to 40 ms either way, one millisecond at a time.

Marksman mounts one tracker on any real rifle, shotgun, or handgun. You do not build a shot detector for each trigger-guard shape. TrueClays ships a replica shotgun; using your own gun needs a custom trigger. The shotgun screen is 12,600 setups: 7 pellet materials, 12 shot sizes, 6 speeds, 5 charges, and 5 chokes. The ballistic calculator behind that screen is built from empirical tests and from the published work of Ed Lowry and John Harradine with the British Association for Shooting and Conservation (BASC). The library already holds 1000+ scenarios, and a new one is a normal step in the scenario tools.

Yes. Marksman opened hunting simulation in 2002, when the first systems went to Swedish hunting associations. Marksman is the original, not the copy, and is still the one leading the way. Later competitors shipped that same form. Development of the original work has continued without a break, through ST3.

Marksman is mainly installed in shops and ranges that serve the public, where the business depends on people coming back. Repeat sessions are traffic and recurring revenue, across rifle, shotgun, and handgun, not only clay.

Yes. Software updates are included in the ST3 Trainer Pro license, together with basic support. Marksman keeps the system on the latest features. TrueClays charges for each update.

Yes. The Marksman simulator is fully mobile, and it does not need an extra screen calibration when you set it up or when you move it. TrueClays is incredibly complicated to set up. That setup is fragile, and a problem can mean sending the system back to the factory.

The error can be very large, and the system is then inaccurate. A laser cannot solve that. The camera can still find the laser spot, and the spot is still drawn in the wrong place, because the map between the wall and the picture is wrong. Marksman holds the screen map at 0.1 pixel with subpixel image processing, the same result each time.

Marksman ST3. The published path is 1 ms and 0.18 MOA on the real shotgun, with a screen map that does not depend on re-shooting a cross. TrueClays fits a clay-only lane whose coaches already live in its analytics and will keep calibration and Perceived Lead under control.
