PNV-57
The PNV-57 is a family of night vision binoculars produced in the soviet union. The design has several variants, either using generation 0 or generation 1 image intensifier tubes. They use an external power supply, with a high voltage cable connecting the supply to the binoculars. Most variants then require an external power source to be connected to this power supply. Originally these units are mounted to a tanker cap style helmet with the power supply worn on the back of the cap.
