You should be chasing for spec values but they don't exist and if you wanted to know what "better spec" values are there isn't a way to know which unit is desirable over another.
Most retailers will post this info as they resell NVDs, first come first serve, and depending on their grading scale of high, mid, low tier it may differ from retailers. If a retailer offers a “ready to ship” fully built units they won't list the spec values. Hand select isn't 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 doesn't negate 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 tryhard game

The numbers to meet or beat are
EBI over 1, over 0.6 is ok, 0.1 is shit
Halo over 1, anything under 0.7 is gay
SNR, under 25 good, anything over 30 is terrible
Photocathode, 1900+ is pretty horrendous, 2500+ is irredeemable
Resolution of 64+ is undesirable, 72+ is 80s tier

feel like we should start including information on thermals in the OP aswell now

>>63902332
Making an infographic for that this weekend, hopefully.

>>63902722
it might be a good idea to make it a multi page thing
one image for scopes and clipons, one for monoculars and scanners, and one for ECOTI

>>63903336
its also a good idea to bring up resolution, digital zoom, lens diameter, detection range, etc.

Not sure if I should ask in /gq/ or not but I'll ask here first because /nvg/ related. What's with the Viper A5 helmets on JRH? I have a Viper Galvion which cost three times the price. Is this the same?

>>63903340
>>63903336
Very good ideas. I'll structure the thermal scope / clip-on buyers guide into a price bracket setup also.

Opinions on what is the minimum needed to drive without headlights on? I recall being fine with an Army PVS-14 monocular, but idk if low or mid end civilian ones stack up behind the wheel

>>63904541
General rule is gen 3 by itself is okay if you have a moon. If you have bad lighting or gen2 unless you have a really high contrast road surface you will need an illuminator if you're moving faster than foot speed.

Seen multiple soldiers sent to the hospital for low speed vehicle impacts under NODs. Worst was air medevac of two guys who drove perpendicular into a dry riverbed - one broken leg and one concussion despite driving under 25mph and wearing helmets.

>>63902321 (OP)
Wheres SMS schizo? We neeeed more SMS posting to complete the /pfg/.

>>63905362
He fell off a bridge. Oh no. Anyway.

Lasersneed is a psyop so anons waste money on laser pointers and not oneleaf thermals. Focus on force multipliers, not memeshit peddled by sellout youtubers.
Change the state of play. Entire crew with digital NVG30s and gym memberships will DOMINATE a single sissy with 2000 FOM he went 8k into debt for and is living out of his granny's 98 buick because the debt went on mom's amex copper. Trailer trash.

he returns...

>>63902321 (OP)
kek

>>63905772
He will rise again and spread the gospel to the walking loot drops here who will face eternal NGMI unless they change their ways.

>>63906560
You can equip three men with HFXCs for the price of one man with an IRIS. If two men are blind and laserless, what is point of the IRIS?
Save money to spend money on force multipliers.

>>63905897
thermalfags will usually be the ones to come out on top though
get a oneleaf scope and you can simply plink off at a bunch of guys in night vision far outside of their IR range

>>63907098
Thermal optics don't really work. I guess maybe militray grade for 10s of thousands of Euros. I got the thermal sight and tried watching last night and didn't see anything except my own reflection in the sliding door. I tried to enhance the img with a UV flash light from Amazon and that didn't help at all! Basically wasted 2k€. If you think you can be a "elete operator" like in the movies, you can't. Don't waste time or money.

>>63908071
what optic did you get?
anything under 640p res is probably gonna look like trash

>>63907098
Which is why the meta is HFXC and Oneleaf.

>>63908078
Something 1000. I'm just saying, stumbling around the neighborhood at night pointing your murder stick at everything you want to see is a lunatic move a d drones will get the cops called when people are tyring to sleep. Plus this thing doesn't even have a retical.

>>63908078
He's trolling, LWIR thermals cannot see through glass like a sliding door. MWIR might be able to, but that's $60,000 and up stratospheric stuff like the HISS-XLR or HD.

>>63908187
oh yea i guess my reading comprehension is just shit lmao

>>63908190
It's sadly the biggest drawback of thermals that they get beat by windows. SWIR-MWIR fusion may rectify this in tbe future but that's at least ten years out.
If the Chinese are smart they'll bull rush into deep SWIR digital night vision, then nobody with analog NV can see their illuminators / lasers. Huge game changer.

>>63908215
i feel like its not as big of an issue as people make it to be

>>63908215
>biggest drawback of thermals
So why no Russian glass umbrellas?

>>63908239
It means you cannot use thermals to drive and will be missing a lot of stuff in urban environments.
>>63908260
Because they do nothing against visual sensors and lack the flexibility of a poncho, which is being used incorrectly in that vid.

>>63908260
>glass umbrellas
because then the thermal sees a giant blob running around. Thermal's biggest downfall is having to nuc, low battery life, and depending on what configuration you use either a jack of all trades thermal master of none or master of one that limits the application. Get a one leaf thermal scope and you have something that can digital zoom out to 100 yards nicely but it can't be used for COTI or helmet mounted. Get an RH25v2 and you have a COTI/helmet mounted or even rifle capable device but it can't zoom in for crap - though it is good at identifying.

>>63908280
driving around at night with a 40 degree field of view with nvg is just asking for trouble though, and i feel like thermal vision's main strength is in scanning and as a scope, goggles have an entirely different use
infact its probably stupid to compare night vision to thermal because each one calls for use in their own situations

>>63908457
Also the oneleaf is a fraction of the RH25v2's price. To extend runtime you need to first use better batteries, Vapcell F38 / N40 are ideal, then a USB-C battery pack if more endurance is required.
Oneleaf's thermal also doesn't NUC, it's some weird processing they use. This is huge and gives it a feature normally exclusive to BST sensor thermals like the old Raytheons. VOx sensors almost always have to NUC, including the RH25.
A downsized 25mm lens version of the Oneleaf with a 384 sensor would be an excellent low-$ COTI. Throw in digital NV and if it keeps below a grand you have /pfg/ locked.

>>63908488
Driving with NV is done out of necessity. Thermals can be readily used for the same purpose if there's no glass involved, NETD is low enough, FOV isi high enough, it doesn't NUC, and sensor resolution is 640x512. Lower than that I'd be worried about missing shit.
You're right about thermals' comparative strengths to I2, but if MWIR sensors and lasers take off we could see thermals supplant NV entirely by 2045.

>>63908491
Don't reply to me you shit eating faggot.

>>63908508
schiz cabron

>>63908491
>NUC
>what's nuc?
Inb4 what NUC with you?

> Introducing ZULU SHD V2 — A New Way to See Your Target Clearer in Low Light
Who tf gave out my email? And wtf is this Zulu SHD VM2? And is it better than the 1Leaf MT1000LF? And how much is it? And will we really find out 07-02-2025?

>>63909565
NUC is when the thermal sensor has to briefly freeze every so often to recalibrate. Cheaper sensors have to NUC more and for longer.

Digital NV. Taking preorders apparently. The Oneleaf is still the mog king.

>>63909613
>great British shooting show
>all 7 guys at once

Lmao

>>63909758
Tha wacko "fishing coaster" gets me. I mean it has potential, but what Scottish majik is this?

>>63909758
Yeah this ain't laying a finger on the Oneleaf. It'll be $359 on ebay used in five years.

>>63909798
>ain't laying a finger on the Oneleaf
>no price point yet
Sounds like a coperroni pizza, 1 leaf shill.
