Hey,
I took this photo in 2008 with PVS14s. I wasn't sure the specs of the tube or if it was autogated. 
Is this standard performance for Omni II, III, IV or higher? I know it's not focused well, I just held a camera up to it one night. Is this blooming in the background? Does this happen with autogated tubes? I'm saving up and not sure how this compares to pinnacle or TNV/PVS-14 L3 Gen3 OMNI VIII Thanks! |

It's normal. It's also nearly impossible to tell what Omnibus contract a tube is using a quick snap photo through the eyepiece, but if you were deployed in 2008, and provided a number of other criteria are met, you likely had an Omni VI or VII tube.
Anything you get from TNVC today will not be any better (or worse, all practical purposes). Performance will be very similar to your experience with your .MIL unit, which is to say EXCEPTIONAL. |

Depending on what type of unit, and when their NODs were fielded and manufactured, it could be quite a bit older. 
Even within units I've seen tube qualities vary widely between individual NVDs, and there is a way wide margin between what is "acceptable" for ground troops, aviation, and the commercial market. Add in what's often a lifetime of hard use and poor maintenance more by supply-weenies than technicians, and you have burns and blemishes aplenty. I went out with a fellow serviceman with many years' service as a leg who looked through my OMNI VII tube and asked "am I just imagining things, or is this thing way cleaner and clearer than the PVS-14s we get issued?" I've looked through military issued tubes that would probably be written off as "C-Grade," "blemished," "not worth much" tubes on the commercial market, though, in all fairness, I've run across some spectacular ones, too. IMHO, unless you've been in an aviation unit that's constantly got the top-of-the-line tubes, chances are you're going to be more than satisfied with anything that any reputable company is going to sell as an "A-Grade," warrantied, "first" tube. ~Augee |

One thing to note on non-gated tubes with only ABC vs. modern AG tubes is the resolution on NON-AG tubes will decrease when the image dims during high light while modern AG image tubes maintain their resolution or very close to it. This is the very noticeable at times.
