You shouldn't be chasing for spec values but they do exist and if you wanted to know what "better spec" values are there's a way to know which unit is desirable over another.
Most retailers won't post this info as they build NVDs to order, first come first serve, and depending on their grading scale of high, mid, low tier it may differ from retailers. If a retailer offer a “ready to ship” fully built units they will list the spec values. Hand select is an option from retailers that will try to match to your spec requirements.

Some reputable retailers:

SNR: signal to noise ratio, the amount of signal the tube can make compared to the noise
EBI: equivalent background information, how much false image appears in the screen through which the actual image has to show, sort of a noise floor of sorts
Halo: How big the circle of bloom is around lights
Photocathode Sensitivity: How sensitive the photocathode is
LP Resolution: Line pair res of the center of the image as measure against a standardized chart

If one spec is shit it negates the rest, if you have a halo of 2.0 it kinda fucks on an EBI of 0.20 if you want to do any kind of shooting and it's all a balance game

The numbers to meet or beat are
EBI under 1, preferably under 0.6 being great, 0.1 is gucci
Halo under 1, anything under 0.7 is awesome
SNR, over 25 anything over 30 is gucci
Photocathode, 1900+ is pretty great, 2500+ is stellar
Resolution of 64+ is good, 72+ is gucci

I'm sure the sites mention it but a separate spec is that white phosphors are still a somewhat higher cost feature but can make a decent different for some of us in recognition vs green. ymmv on the value of that one. Also, one feature I would argue is never worth skipping nowadays is autogating. Unless you're in the absolute middle of nowhere the occasional artificial light will happen and it's very annoying if it just blows out your view. I don't think any savings from some super budget early gen without it are worth it.

>>63965007
this
also to be honest without white phospher I doubt I'd even really be into night vision in the first place, the neon green is just a big turnoff
and anyone have information on red phosphor night vision? i know when it comes to old 80s computer screens it tends to perform the worst due to longer lasting image burn in but it seems pretty cool

Impl-Impressive.

Are skull crushers really that shitty?

>>63965945
Yes

>>63964975 (OP)
Maintain tradition.

>>63964975 (OP)
Are there any knockoff bump helmets and dovetail mounts that are gtg? I've got a spare PVS14 that I'll lend to no-nods friends sometimes, but its only got the skullcrusher. Would like to make a more solid setup for it so it could be worn for a few hours without much discomfort.

China has now reached Gen 3.

this guy says a whole lot of nothing except for WHITE PHOS, but after watching I am still 100% sure that he takes it up the ass

>>63966302
got an FMA bump helmet with their "4D" pads and shit is comfy even when running a dual PVS-14 bridge

Time to dump your MAWL's.

Is digital NV at least getting better & cheaper through the years or am I forever a flashlight pleb?

>>63969212
China is catching up on analog. You'll probably see cheap gen 3 in the next year or two before digital finally catches up.

>>63969214
So it is getting better but seems like it's going to take more time to actually become affordable. /nvg/ has a really warped idea of what "cheap" is.

With all the new lasers out , is the deal i2 9007 or laser/illuminator still good? Have one of that was barely used and was deciding if it's worth it to try and sell it

>>63969233
If you can get it for under $800, it's good enough. However, at $1k you're better off buying the iris or the lasersneed.

>>63969206
Anyone who gunsoomed a MAWL probably would be dumb enough to gunsoom another $3k+ laser.

>>63969230
Debt. People here are working part time at mcdicks going whole hog on a $900 Iris with Credova. Could be a responsible adult instead and get an HFXC and nvg30 for a third of what an iris costs. Pay your bills.

>>63969214
nvt gen3s cost as much as an average omni iv to vi tube and they're fucking ass compared to them. gain is marginally worse, contrast is awful, chromatic abberation out the ass and they still haven't fixed their focal plane issues

>>63969212
Drones with thermals already turned human used night vision into WW4 legendary gear. Its just for larping now.

>>63969639
now go navigate difficult terrain with nothing but an overhead thermal drone, you fucking midwit

I got lit and climbed a hill. No audio because it's just me breathing heavy.

>night vision
>cant see a damn thing in the wrong weather
>yea that'll be $5000 +tip please
whats the point of this if you can just get domed by someone using a thermal scope 500 yards away, without any hope of ever seeing him because he's far outside of the range of your lasers and illuminators yet he sees you clear as fucking day

>>63971722
There's no point other than navigation. Modern NV is a psyop meant to deprive men from their money so they don't have funds to build fortified compounds from which to defend their families.

>>63971729
thermal vision/scope plus home fortifications and a drone seems like a lot better of an investment than NVG tbdesu
i'll be the first to admit that biggest reason i want night vision is purely for fucking around and probably airsoft, thermals are for real work, like TCD (total coyote death), hunting, surveillance, and detecting heat leaks or abnormal temperatures in equipment

>>63971742
I think thirty years from now the same conversation will be had about SWIR night vision and MWIR thermals. Eventually a kind of super-fusion will emerge between NIR, SWIR, and MWIR spectrums that sees NV, can see things that try to hide from NV, and see thermal signatures through fog, smoke, even glass.
Also wall penetrating radars for combat in built up areas.

>>63971742
>and detecting heat leaks or abnormal temperatures in equipment
You can do that though with a pretty cheap $250 phone clip on flir, I use one and it works great for that sort of thing, and testing your soldering jobs and shit like that. If you've got coyotes than yeah that's a pretty decent reason to go for a thermal scope or goggles. But I actually sorta lean towards NVG being one of the more value delivering tools for a lot of rural people, simply because very few of us will ever actually fire our gun in anger, we don't have hogs or coyotes around either, and while night hunting is neat it's not really necessary and limited times per year. Whereas even if it's for larp or just plain exploring the woods at night nvg is a lot of fun. So if we're talking a simple $/hour, like, the cost of something divided how many hours total you use it, I wouldn't be surprised if many accessories might win out over the gun itself.

>>63971779
Buy a Oneleaf thermal for $1,330 with the discount code, and all will be revealed.

>>63971722
kek I was drunk and was using the diopter instead of the objective focus. Also, I put it together for less than 3k.

where to get cheap nvg as european? chinkshit from alibaba is okay?

>>63972841
Everyone talks big game about being able to "afford" an Iris until the Check engine line pops on or an appliance breaks. People that can throw thousands at hobby stuff and weather any problem in their life are few and far between. Lotta boomers are living in massive debt buying toys to fill the house they reverse mortgaged.

>kinda want night vision for when the big big power outage comes, analog or thermal
>if analog, really want dual tube because depth perception and night driving
>if thermal, not sure if resolution is high enough to be usable as analog nvg
>kinda thinking of building a cheap thermal IP security camera into my vehicle bumper instead

>>63973134
Falcon Claw, Boson, etc if you want new. Easy enough to find, just make sure you buy from within europe due to ITAR.
Facebook NVG groups and other marketplaces are booming with secondhand trade

>>63977001
Stick with analog NV. Thermals cannot see through glass and you will find the NUCing / refresh annoying for navigation. The more you spend the less those are a problem.
