No, you probably shouldn't buy a PVS7.
Biocular night vision has all the downsides of monocular night vision, none of the upsides of monocular night vision, and even a few downsides unique to itself. This video is a comparison of the principles of biocular night vision (like the PVS7 and cheaper NVG7 or WOLF7), and monocular night vision (like the PVS14 and cheaper NVM14 or WOLF14). More of a theory video, and not a review of the housings themselves.
