The NVD-BNVD-SG Binocular is a dual tube goggle with gain control. The BNVD-SG operates with a single gain control knob that controls both eyepieces simultaneously. Depending upon the amount of ambient light, the user can adjust the tube brightness (gain) lower to compensate for overly bright conditions or to increase the gain under extreme dark conditions. The BNVD-SG can be used as a monocular by choosing which side you want to use as your night vision eye and rotate the other side/arm of the binocular up and out of the way. This enhanced capability allows the user to rotate either monocular channel away from their eye while leaving the other monocular channel in place. This provides the operational flexibility to use the BNVD-SG as either a dual-eye or single-eye device. When used as a monocular, the user can operate the BNVD-SG with weapon mounted sighting equipment without sacrificing night-time situational awareness. Best of all with all the added features, the BNVD-SG is still substantially lighter than the AN/PVS-7 single tube goggle!

NVD-BNVD-SG now features a 'Tactical Monocular Cutoff', which turns off power to each channel of the binocular whenever a channel is rotated up out of the users' line of sight. This eliminates stray light emitting from the monocular eyepiece, which would reveal the user to anyone else on the battlefield. The BNVD-SG has an automatic system power cutoff whenever the BNVD-SG is flipped up into the helmet mounted stow position, and then powers back on when it is flipped back down. This feature can also be turned off via a four position ON/OFF switch. The BNVD-SG is submersible to 66 feet (20 meters) for up to 2 hours. The BNVD-SG is available with an optional battery pack, which holds 3 AA Alkaline batteries for an additional 85+ hours of run time.

The BNVD-SG can be used with optional 3X Afocal Magnifiers. Each 3X Magnifier can be either slide onto each objective lens or screw into the threads on the objective lenses. For extended use, it is recommended to screw them on to prevent the lenses from falling off. These magnifiers transform the BNVD-SG into a fixed 3X Magnification Binocular. The optional external battery pack will only work with our Night Vision Devices manufactured binoculars with an external power port in order to extend the operating life of the system. If you would like to use this battery pack with this system, you must add the power port now when first assembled. The body cannot be modified afterwards. You may however, add the battery port now and purchase the battery pack at a later time.

The BNVD-SG has been rigorously tested for US Military and DoD EMI compliance by an independent, Gov't support facility, and qualified for conformance to MIL-STD-461G, RE102, RS101 and RS103. This means that BNVD-SG has an extremely low electronic emission signature, making it nearly impossible to detect its use, even in close quarters. The BNVD-SG was also shown to not be damaged
