The small, lipstick-sized device is clamped below the barrel of the rifle or pistol during regular training sessions. A special infrared camera downrange monitors the action. Coaches can watch the targeting in real time, while the session is recorded for later review with the athlete.

If they're losing concentration, their hold will be poor and they would be all over the target. If they jerk the trigger they can't stay aimed properly. The laser shows what they can do better.
