Well I tend to run my -14s close, and my -7s with the eye cup folded back but almost touching, as in I sometimes feel my eye brows touching the folded over cup so it maybe fine for me.

No, if you buy bare housings, my understanding is that it is assumed you are already an expert in the field and can perform proper tube installation and have the tools for proper installation. You're basically just buying bare parts and it is no different than buying bare car parts or parts for anything. The housing is a "kit", but only in the sense that it comes complete with everything the end user would need to get them going once the tubes are installed. You'll get a manual, but it will be about device operation, not building the device.

Seems extremely likely that at a minimum the housings are identical.
Probably not going to be a hard confirmation from anyone official.

Nice, how's the eye relief and usability of this setup?
Link Posted: 5/6/2020 4:05:40 PM EDT
To set the stage for review: I've spent a grand total of ~1hr under nods, a little with some friends gen2 goggles (surplus aviation maybe?), the BNVD-40 (gen3 thin film green) ,  and an assortment of single PVS14s and the majority just running around the house with these new ones.

I cheaped out and went for an un-specified gen 3 tube, and personally I'm glad I went for the binoculars over a higher spec single tube system.
Eye relief is shorter than I'd like, so my normal shooting glasses touch the eyecups, but not enough to cause a problem yet.
I was afraid of fisheye/distortion from the 51deg optics, but honestly I don't really mind it. As the OP noted, it's not terrible and a bunch of years wearing less than perfect eyeglasses has made me tolerant.
Haven't gotten a chance to get out on the range or do any night hiking due to the current lockdown situation, so have a cell phone photo of my well lit suburban neighborhood:

Same question, as I really don't want the eyecups.

Everything I've seen that was "permanently afixed" or "retained at all times via mechanical means, e.g. tether" has magically been "made removable".

Just required a big enough pair of cutters.
Link Posted: 5/6/2020 7:38:28 PM EDT
they do come off, but on some of these smaller diameter lenses, you might actually prefer the eyecups. I will be curious about your feedback when you get them in hand.
Link Posted: 5/7/2020 2:38:11 AM EDT
has anyone tried driving with the 51' lenses - i hear they are slightly less than 1x mag -  does that affect  distance perception enough to make it harder to drive ?
if they work ok the extra field of view would be nice
Link Posted: 5/7/2020 9:59:38 PM EDT
Do you think it’s worth it to take the tubes out of my loaner dual 14s and put in one of these housings?
Link Posted: 5/7/2020 11:02:03 PM EDT
Not if you already have dual 14's.

The mag issue did not effect me when I was walking around for 30 mins. The wider view is okay, after seeing it I can live with out it. only time it is even really noticeable is when looking at things closer than 30 feet. Maybe if a tac situation the wider view could keep you alive but for normal use its not a huge deal. When looking at things further away I tended to look at the object, and center it in the view so the wider view did not matter.

Also they just raised the price on these by 350 bucks.

Got the PVS14 compatible AGM 51 lenses in today.   Housings are aluminum (or at least non magnetic mystery metal) and the glass looks pretty clear. The RNVG housing is 2 to 4 weeks out, so no thru the tube evaluation yet. Looking at engineering grid paper thru the glass, the objective fisheyes at the edges, the eyepiece optical element does not.

Holding both optical elements inline, it looks like the eyecup is going to be required to get a good picture given how much smaller the lens is. Slight fisheye at the very edge of the glass, but not over a majority of the increased FOV.

For a 100% unscientific test, at a distance of 11 feet from a wall, with the floor at the bottom edge of the fov, I can see my ceiling in the top edge (about 7'8" from floor to ceiling). With a PVS14 40 fov lens, I can only see a range of 6 feet, from floor to part way up the wall.

I'm really curious how this is going to look all assembled.



Link Posted: 5/16/2020 8:34:50 AM EDT
I have really only noticed fish eye effects if they are slightly off axis while viewing. If you have them lined up correctly, the image is quite good.

Very similar to eyeboxing issues with scopes.
Link Posted: 5/17/2020 12:48:14 PM EDT
Any issues with walking around with the 51s over the 40? Is it similar to your normal eyes or does it through you off? I’m trying to decided between the two.
Link Posted: 5/17/2020 1:29:22 PM EDT

At $1350 I agree, better options for not much more money. At the price of 1000 I paid I am happy enough that I will probably keep it.

I have about 2 hours on mine now, I have learned to live with the weight, and field of view. I was out walking under the trees the other night, bush wacking, not on a trail and had no issues with the mag or lack of magnification. the depth perception is good. When I got to a field I saw and IDed a deer about 200 yards away, just star light no moon. I could see it as a dark spot in the field.

Gotcha. That makes mor sense than the simple dollar figure difference. Your last update made it seem like the price increase was the final straw.

The flair is there, best way I can describe it is dirty windshield. You know how when your windshield is dirty and a another car is 90 degrees from you and their lights hit your windshield you can "streaks" of light across. I can see it being a problem for some in a high light environment, but in my situation where i have basically no lights around me it does not bother me.

Is it perfect, no, it is worth the weight difference and the bino setup to me for 1000 yes. Call it the pvs 7 of dual tube binos, it has its flaws but for the price I can live with it, or use it as a stepping stone to something better.

Too much misinterpretation that the AGM is just as good as domestic binos on the market. I didn’t try to frame the information that way, but it was overwhelmingly received as such. I’ve gotten over two dozen PMs from different guys trying to convince themselves these are good to go compared to an RNVG with mil spec glass.

AGM/Apache (importer) are undercutting quality, dependable American made products produced by American small businesses out of American materials.

Nonetheless JW is correct. The original content you posted was good and useful info and should not be self-censored. You could have amended the first post with a statement in ALL CAPS explaining what you just wrote here.

Wiping out useful information from public domain is what countries like China do.

Never said I was entitled to your writing (prolly what you meant?). You are free to censor your own posts, sure.

Many of us are on here to learn and to share information about night vision devices with each other. Whenever I read a well-written and detailed post on a night vision device many are curious about (that most don't yet have access to), I appreciate that much more the community and growing knowledge base here that Vic and others have built. Whenever some of that information suddenly disappears, it diminishes that and feels less like the American ideal.

I, JW and others here actually LIKE what you wrote and found it useful. So please at least take that as the compliment it is intended to be.
