This was the first gen 3 night vision unit I have used and I was blown away by the optic’s clarity. Using the optic at night basically makes it seem like daytime but with everything being green. This is a real PVS-14. The package includes all the accessories of a standard military PVS-14 and the unit is extremely high quality. I found that using the optic as a monocular or mounted behind a riflescope are the most effective uses for the PVS-14. The head mount is cool but takes a lot of adjustment to get it just right. Mounting the unit to a helmet would most likely be much more effective. This is “real deal” night vision and would absolutely recommend it to anyone wanting extremely high quality night vision.
