The crosshair is the most basic reticle for the AN/PVS-4 and is available as either a simple crosshair, A mildot crosshair or as an aimpoint crosshair. A simple crosshair reticle can be seen on the photo taken through a surveillance AN/PVS-4. The image was taken during a wide-area blackout on a moonless night in a remote suburban area.

The crosshair lines geometrically resemble the X- and Y-axis of the Cartesian coordinate system , which the shooter can use as a simple reference for ...

Stadia marks on a crosshair while viewing a metric levelling rod. The top mark is at 1.500 m and the lower is at 1.345 m. The difference between the rod readings is 0.155 m, yielding a distance to the rod of 15.5 m. A typical surveyor's instrument reticle has two pairs of stadia marks. One pair are on the horizontal centreline and the other on ...
