Windage/Rangefinder

The windage scale can be used to make horizontal adjustments or as a rangefinder. Shifting the aimingpoint one division left or right will move the point of impact by 10cm for every 100m of distance. The dis-tance to the target can be judged by assuming that a 1m wide/long object fits between the small divisionsat 100m. Therefore, if an object is 5m wide, it will appear 10 divisions wide at 500m

Aiming Chevrons

The chevrons are provided to adjust for bullet drop at 1000m, 1100m and 1200m. Aiming with the 2nd,3rd and 4th chevrons accordingly. Note that the elevation turret needs to be set to 1000m before apply-ing the extended aiming chevrons

Rangefinder

The rangefinder works by placing the target between the horizontal baseline and the curved line with thescale. On the curved line locate the number closest to the point where the target touches the line. Multi-ply that number by 100 and this gives the range to the target in metres.

The PSO-1 is an optical scope specifically designed for the SVD Dragunovas a telescopic sight by Novosibirsk instrument-making factory around1964. It has a 4X magnification meaning that what you see with the na-ked eye at 50m will be the same size through the scope at 200m.

The objective lens diameter of 24mm gives an exit pupil size of 6mm. Asthe human eye only needs in the region of 4mm of light transfer througha scope in normal sunlight this scope will be sufficiently bright for goodweather daylight operations.

The military version of the PSO-1 uses an export restricted reticule cali-brated to a man sized target of 1.7m.
