(4) Sights.—The sighting gear is operated from the left side and is fitted to the left saddle trunnion. The sight bracket carries an open or telescopic sight, and is provided with a lateral-deflection gear, a range drum, and means of adjustment for line and elevation. Magnification of the telescopic sight is threefold. A battery for lighting the graticules for night shooting is fitted.

The range drum is graduated in black for AP (Pz.) and in red for HE (Spr.). The figures 5-8-10-12-14 on the AP scale correspond to ranges of 500, 800, 1,000, 1,200, and 1,400 meters. Ranges of 300, 700, and 1,100 meters are set on intermediate graduations, which, however, have no figures against them.

The scale for HE is marked 4-6-8-10, etc., up to 24. These figures correspond to ranges of 400, 600, 800, 1,000 meters, etc. Ranges in between are set on the intermediate graduations.

A small lever with a worm screw operates the lateral deflection gear. When a tank approaches directly from in front, the lever should be pointed towards the gunner. If the tank is moving across the line of sight, the lever should be turned two notches in the direction of travel (for example, the lever should be turned to the left for engaging a tank moving from right to left). The lever should be moved only one notch for an oblique target. Lateral deflections may be set in this way for targets traveling at less than 12 miles per hour.

For targets traveling at more than 12 miles per hour the graticules on the sight should be used. The central mark should be employed for tanks approaching from the front, and the left and right laying-off marks for targets moving to the right and left, respectively.

The Germans use the following table as a guide to avoid frequent alteration of the sight during action:
Range
(yards) Range-drum
setting Part of tank laid on
1,100 to 880 8 Pz Between top and center of tank.
880 to 550 8 Pz Between center and bottom of tank.
Less than 550 8 Pz Center of tank.
For example, to engage a tank 770 yards away and traveling obliquely to the left at 18 miles per hour, the layer sets the range drum to 8 Pz., moves the lever one notch to the left, and lays the right laying-off mark on the center of the target.
