Since it’s introduction at SHOT Show 2019 the TNVC TNV/PVS-14 PBM-A (Powered Bridge Mount) has been fielded by a number of users, including military, law enforcement, and commercial end-users. The patent pending Powered Bridge Mount is a unique product that allows individuals and organizations that already have PVS-14 Monocular Night Vision Devices (MNVDs) to obtain capabilities similar to dedicated Binocular Night Vision Goggles (BNVGs) at a fraction of the cost of purchasing new devices.
While bridge systems that allow two PVS-14 MNVDs to be bridged together are not in and of themselves unique, the TNVC TNV/PVS-14 PBM-A features a unique power control system that not only allows both PVS-14s to powered and controlled using a single power control knob and on-board AA battery located within the Powered Bridge Mount rather than individually, but also allows the device to use an external battery pack for extended battery life, similar to the USSOCOM AN/PVS-31A BNVD.
The TNV/PVS-14 PBM-A also features a distinctive “yoke and harness” attachment system to provide the best possible image to the end user by ensuring optical and mechanical alignment of the individual PVS-14s, and is stable enough for collimation.* Like the TNV/DTNVS, USSOCOM BNVD, USMC SBNVG, and Army ENVG-B, the TNV/PVS-14 PBM-A is an articulating system that allows the individual monoculars to be rotated up from the center hub, allowing users to move the monoculars out of their field of view without fully stowing the entire goggle. This can be especially helpful inside of vehicles and other confined spaces with low overhead clearance. When the goggles are fully stowed, the articulating feature allows the device’s center of gravity to be located much closer to the head, reducing end user neck strain and fatigue.
Binocular night vision goggles offer significant advantages over individual monocular systems, such as improved depth perception and situational awareness, allowing end-users to process information faster and more accurately. While purpose designed dedicated binocular systems do continue to have advantages over bridged MNVDs such as overall system weight, many individuals and organizations already possess PVS-14 MNVDs and it may not be possible or cost-effective to immediately replace them with dedicated binocular systems. The TNV/PVS-14 PBM-A allows those individuals and organizations to obtain many of the advantages of binocular systems without having to purchase brand new dedicated BNVGs.
