I have been playing around with nite vision for for at least 15 years now and would like to pass along some of what I have paid to learn. Gen 1 stuff is very impressive if you have never seen nite vision before. It is also very cheap compaired to gen 2 and gen 3. That is for a very good reason, it is very low tec. compared to the later stuff on the market. Gen 3 + is the latest you can buy and you can see in some very low light without an ir lite. Gen 2 is far better than gen 1, but you will need an ir lite much sooner. At present I have a Core tec., about the same as gen 2, rifle scope and gen 3 goggles. I can glass an area without an ir lite with the goggles, but usually need an ir for the rifle scope. My opinion as of now, gen 3 + is the way to go if you can afford it. If now gen 2 with a good ir lite will work. I have also played with thermal, a $ 2000 unit, but feel you will need to spend much more to come close to gen 3 nite vision for nite hunting. Now as for gogles, I have the PVS7`s and they work great, problem is they are very heavy and with the head gear on you will get a head ache wearing them. I think the 7`s, which is a monocle would be much better. My nite AR has both a scope and an ir laser on it. The laser is great for fast shots, but the scope works better for longer shots where you have more time to aim. The more you spend up front on nite vision the fewer time you will have to replace it.
