200m Visibility PVS31/SA31 Digital Night Vision NVG

This is a full set of PVS31/SA31 2.5th generation digital night vision.
It allows you to see up to 200 meters in the dark of night.
The view is clearer to the naked eye than in the photos.
The unit can be used on its own, or for longer periods with the external battery case.
The set includes the main unit, 5 batteries, an external battery case, a charger, wiring, and a hard case.

To operate: from the open state shown in photo 3, unfold to the deployed state in photo 4, and turn the knob in photo 5 counter-clockwise three times to power on.
The main unit's battery compartment is located below the knob.

For the external battery box: as shown in photo 8, first open the box and insert batteries. Then, connect the main unit and the battery box with the wiring for up to 7 hours of operation.

The image quality of the scenery through the night vision appears grainy due to the camera used for shooting; it looks much clearer to the naked eye.

There are several minor scratches on the unit from the time of manufacture.

Please feel free to ask any other questions you may have.
