Just to throw in some more info here ITT is a manufacturer of Night Vision Equipment. ATN is an importer, assembler, and reseller of Night Vision Equipment. ATN will also sell products made by ITT.
As for easily getting a workable day night set up Vic has shown the way with, either the aimpoint or EO thingy for 1 X day use. Then throw a 3X magnifier behind either for some distance work. comfortably 150 to 200 yards. lots of people will say 300.
Night time use you have again, either the aimpoint or EO thingy in front of your NVD and if ya need some magnification at night put on the 3X milspec magnifier. Works like a champ. If you need more range out of your set up than that, save your pennies for the D 760.
I know the expense is not chump change for most. I REALLY know this as I buy tubes and each time I have to lay out a couple large for something that just two years ago was a few hundred bucks, it KILLS me.
However... coma pause for effect,
Once you look through good gen 3 night vision, everything else of lesser quality will never do it for ya again, and this is just glassing around the back yard. If you need night vision for work (what ever work that might be) then it is a must.
I have had a LEO out in California tell me about his first felony collar he caught with his spiffy new ITT 6015. It was a high speed chase of a stolen car. Perp leads them out of town into a series of orange groves. It is WAY out in the country and it is very dark. So the guy crashes the car into a field, then flees on foot. The only way they caught him was night vision. The LEO's partner kept watch as he directed him in on top of the guy who had crawled deep inside a bush.
I have known active duty military members who are going to the sand box buy thier own gear as they wanted better than what is issued, plus in one case, a guy's unit just didn't have enough to go around and he was a snipers spotter. Alas there are a ton of military PVS 14s running around with very spotty 45 LPM tubes in them.
So the moral is while this stuff is expensive, in no other field of equipment is this statement more true, you truly get what you pay for.
Night vision equipment and it's use is something that is almost magical. During the first gulf war I was stranded in the desert for about three days and we had to move at night. We did not have any night vision and it was a moonless time of the month. It sucked on all new levels of SUCK. I would have given (and I am not kidding here) a body part for a set of PVS 5s. I still look back on that with dread. It ain't like the movies.
There are of course caveats as to what you buy and whom you buy it from but do your home work, ask LOTS of questions, and this forum is a great resource. Thanks again to Victor for getting it off the ground. This used to be one REALLY long tacked thread in the optics forum that was getting laborious to go through.
So save your pennies and get something you won't be disapointed in later.
