 you know, the targets that people have the hardest time with. So we duplicate that. And then in your own gun, we insert in the muzzle a device called the laser shooter. And the laser shooter has a wire that comes down with a finger ring. And when you touch your finger, your shooting finger, and when you touch your trigger, it fires the laser. So now you've got a moving target that you set up in the direction and the speed of your choice.
