In order to follow up the adjustment of a test gun, and for training of swinging movements, the emission is utilized of a beam of light from the gun towards an electro-optical target with consecutively arranged light sources 44 and photo detectors 45. By means of a particular control device the light sources are lit sequentially, and the position of hit is detected for a beam of light emitted towards the target by a first light source, which was lit at the moment of detection of the beam of light, being brought to light, and by a second light source, indicating the position of the photo detector detecting the emitted beam of light, being brought to light in a different way. <IMAGE> |
