Abstract: Designs of prior art art not usable in efficient dry-run target practice with hand firearms. The greatest drawbacks are, for instance, that it is not possible by the method to monitor the result of the dry-run training; that the method or means is not liable on ordinary guns without special measures or not at all or the method is so complicated that its implementation in practice causes that the means is too expensive to be in the personal possession and use of shooters. In order to eliminate said drawbacks, the invention is mainly characterized in that by a transmitter/receiver means attachable to conventional arms is emitted an optical beam towards a surface serving as the target which is set off from its surroundings due to its optic radiation reflecting properties relative to those of its surroundings, the hitting or missing of the beam being observed with the receiver on the basis of the return beam.

Abstract: An optic method for shooting practice in which a narrow light beam is used instead of a bullet. The light beam is provided by a light transmitter (2) of a visible or infrared area attachable to a gun, the ray transmitted by which transmitter is observed with a spot-sensitive optic detector (5, 6) from which is received continuous position information during aiming and discharging as well as, when desired, also the hit and the direction at the discharge instant (9). (FIG. 1).
