Small Arms Review just did a pretty decent article comparing Gen 3, Gen 3 enhanced, and Thermal imaging, and discussed the early NV gear. I wish I had held off and gotten the Gen 3 enhanced. But back then they were playing with Gen 4 and still hadn't a clue that it wouldn't work.
OK, so it depends what one intends to use it for. Based on the article... TI was/is pretty incapable of discerning details. When seeing a person all one could see was the light colored sillouette. Good NV allows seeing details, like if a rifle was being carried. With TI one can't see the rifle easily. But the person was very easy to see since he "glowed".
I'd like to have a hybrid unit, both NV and TI, and merge the images for the best of both worlds. Yeah, and I'd like to have the taxpayers buy it for me too.
Yardburd, good NV or TI, if you can swing it, allows you to totally own the night. Combined with amplifying earmuffs, and a suppressor one is a force to be reconed (sp?) with. The first 2 are self explanatory, the suppressor is the best flash hider one can buy (even if one has NV and is looking for the flash), and the target can't tell where the shot is coming from. The blast is absent, and the sound wave from the supersonic round impinges the ear at 90 degrees from the direction of the bullet passage, not from the source of the shot. So one can see, hear, and not be detected even if shooting. Of course TI would easily spot the shooter and see the hot suppressor.
Let's see if I can make this work... No, it reverts back to the direct link. That's the pits.
The PVS14 is mounted behind the sight. The sight does what it does day or night, the PVS14 is mounted or not and uses the sight for aiming. Yeah, I live in a free state that allows cans.
