Day and night periscope sight «Manul» is designed to replace the sight 1PZ-2 in armored personnel carrier BTR-80. The sight is installed into the place of the sight 1PZ-2 without any modifications. The sight has a device of the third generation, which allows using armament BTR-80 at any time of the day. The angle of elevation of the line of sight for a day and night branch corresponds to the angles of elevation of the main weapons of BTR-80 (-4º to +60º). Target range is entered by the operator and displayed in the eyepiece. The type of selected weapon (KPVT or PBC) and the elevation of the target are also shown on the display. The sight is equipped with a special connector that allows, not removing the sight from the car, to change the ballistic amendments introduced in the memory of the sight (e.g., for its using with arms, different from the standart weapons BTR-80, or with a different type of ammunition).
