The simulator can be used with most shotguns and rifles. The camera sensor that registers gun movements and shooting direction can be easily attached to the barrel of your own gun. The shooting direction is calibrated by a single shot at a calibration target. The shooting scenarios include moving and fixed targets. Starting position, trajectory, speed of the targets are parameters that can be altered by the user creating a wide variety of scenarios to practice on. Hit position and the effectiveness of the shot are evaluated according to all contributing factors: ammunition load and weight, range, target size, trajectory and speed.
As you can see in the following ST-2 video, the shooting simulator also lets you choose from among different targets; bears, ducks and moose are offered as shooting practice.
The ST-2 shooting simulator is pretty close to the imaginative virtual shooting range described by Clifford Simak in his 1963 novel Way Station. Enoch Wallace, the Civil War veteran who mans the galactic way station, asked for something that would challenge him - something along the lines of a shooting range. He was given a lot more than he bargained for:
The basement was huge... carved deep into the rock that folded up to underlie the ridge...
Finally the gallery widened into an oval room and the walls here were padded with a thick gray substance that would entrap a bullet and prevent a ricochet.
Enoch walked over to a panel ... and thumbed a tumbler, then stepped quickly out into the center of the room... He stood on a little hillock and in front of him the land sloped down to a sluggish river bordered by a width of marsh.
Enoch felt the hair crawling on his scalp and he thrust the rifle out and ready. The very air of this place - wherever it might be - seemed to crawl with danger.

Like the ST-2, Simak's virtual rifle range offered a variety of targets, including wolf-like predators with smooth faces and toad-like monstrosities, among others.
