There are many NVG systems out there, but the ones I have used on a regular basis are the PVS-14, BNVD (Binocular Night Vision Device), and DTNVG (Dual Tube Night Vision Goggles).
The PVS-14 is a monocular system that is used over one eye. There are several advantages to this system but the biggest is price. This is generally due to the other two having two image intensification tubes as opposed to one on the PVS-14. You will also need to purchase a J-arm for the purpose of mounting the PVS-14 to a helmet.
The PVS-14 comes with an on/off switch and IR flood switch. The PVS-14 comes in 1 or 2 Aa-battery compartment models.
It is manufactured or rebranded for a number of companies including Armasight, ATNM, E-otech, Bering Optics and FLIR. Prices range from $2,200 to $42,499 depending on options.
The BNVD and the DTNVG each have two image intensification tubes, which allow you to look through both eyes at the same time. Both of these units have a dovetail interface that mates with the NVG mount. With these units you do not need to purchase a J-arm. The BNVD and DTNVG come with on/off and IR flood switches. Both have CR123 battery compartments.
BNVD-G: $7,914-$8,274 DTNVG Dual Tube Night Vision Goggle: $8,730-$9,900
