The RNVG-VG is a further direct variation of the original RNVG fixed-bridge goggle design which redesigns the system for compatibility with standard 11769 image tubes typically found in the PVS14 monocular. This means that users of existing PVS14 monoculars who want to upgrade to a dual tube platform have the option of utilizing their existing image tube, paired with a second similar tube, in the RNVG-VG as an easy step-up that requires no tube modification. The RNVG-VG utilizes a four setting gain control knob to control output brightness, and a new throw lever control style. This goggle is an excellent option for those looking to go from a monocular to a binocular night vision system who do not have the ability or desire to sell their existing system, but also may not want to have the expenditure of an entirely new goggle.
