Very reasonable price, no objections extent. Included software installed on Windows XP computer, tried camera, good! All interested parties who wish to inspect runs thus be said, the measured diameter of the camera head without the small ring at the head end is 7.40mm and not 7:00! With screwed ring there are 7.70mm. For caliber .308 (7.62x51mm) so it could become scarce. The K98 and 8x57IS it works very good though.
