Brand new to NV/Thermal. Should I just skip all the research and impulse buy a GF31?

My thought process:
*Thermal is necessary/clutch for spotting humans/animals
*Clip on thermals aren’t nearly as good
*Downsides of digital NV don’t seem to apply much if at all here since the latency is so low and the thermal compliments the night vision and such a way that it makes up for some of the short falls.

*I saw videos also where someone had dual NVG tubes, but with the clip on the thermal, but the thermal capabilities seemed very weak compared to a dedicated fusion
* I saw a video where the set up was one tube was night vision and the other tube was thermal, which seemed pretty cool, but it doesn’t seem to work as well together since each eye looking at different things. The one cool thing I saw them do, though is that they would pop the thermal tube off their helmet and then pop it onto their rifle pretty quickly, which seems like a cool feature.
* it just seems like a really good plug-in play option. A few years ago, I had done some tactical training with guys who had been doing NVG stuff and they all complained that it was such a pain figuring out which mounts go with which tubes and helmets and getting everything working well together just get it all set up.
* from Grok: “The GF31 runs pure night vision at up to 100 frames per second. In outline mode the night vision side stays at 100 fps while the thermal overlay is limited to 50 fps, and full fusion mode drops both to 50 fps. That 50 fps figure is standard for thermal sensors and feels smooth with no noticeable lag for walking or scanning,”

Nvg

Im looking for a tube for this night spirit mp. I know the tube is made by ekran and is 43mm and its short so if anyone has one let me know.

Finally did the cheapest upgradable NVG

Here It Is, I wanted a super cheap solution for who wants a diy night vision instead of buying some NVG that give almost the same results but cost 5/10 times more.

I made It with 75€ (83/85usd?).

I designed and 3d printed all the enclosure and various parts, as the wilcox mounting. What I bought are an IMX sensor from ali (40€), a cheap lcd from an old camera (you can get It for 15/20€ from ali), a plexiglass lens protector from ali (5€) and a 3x zoom Lens from ali (8€).

The weight of this Is under 250grams and It uses a 11.1v lipo/lion battery, the length Is 180mm with the eye gasket on, 145mm with the eye gasket off.

It works with analogic signals so it has an almost inexistant input lag (10ms).

It handles well little light and clear night sky conditions, so I suggest an IR 940 Torch (20€) so you can see in total dark conditions too.

This Is a pretty nice experiment that can be upgraded to Thermal Imaging in less than a hour, so with a Total of 200/300€ you can compete with way more expensive solutions like some analogic NVG's without breaking the bank.

It took a lot of effort so I hope you enjoy this summer project :)

Homemade digital NVGs

Built this over the last month or so and got a bit carried away with it, if anyone has any recommendations for better sensor/ hardware/ software or any advice at all I’d be really grateful as always keen to improve my builds. This setup is using an IMX462 sensor plugged into a raspberry pi5 running just off libcamera with an OLED screen and optics plus IR illumination- low light performance isn’t as good as i had hoped especially after seeing people’s GNG2K’s on here. Hoping in future to make it a little sleeker and tidy up the cables, mount it to a helmet, possibly get a 940nm laser illuminator instead of 850 nm LED and finally integrate a thermal overlay or have a second ‘tube’ as thermal long term

GNG2K Optimal Setup (So far....)

Thought I'd post my GNG2k pano setup as there have been a few questions about mounting options.

I tried almost everything and this is what I've found to work really well. The screen layout of the 2K is excellent as a pano setup, latency is fine and it works with a USB battery pack x2. These work fine in the unit and I had read the 2K has inbuilt tech to manage USB power. Seems so! Not fully tested the battery life yet but north of an hour so far:

GNG2K x 2 on 3d printed pano adapters, with fabricated wedges (GRP with a dremel and a file). Link for pano adapters: https://makerworld.com/en/models/2359543-gng2k-8-degree-pano-dovetail-adapters#profileId-2581422

Clone KVC.

Clone Cadex shroud.

2 x low profile 50cm USB cables.

2 x small USB battery packs.

Clone SC battery bag.

I've also put lens protectors and cable ties for bungee mounts on the 2ks.

Hope this helps you guys.

Gng2k mount help

Trying to get my new setup squared away after upgrading from a nvg10. The botttom mount works fine I just don’t love the single screw mounting being the only thing holding my NV on. I got this duel mount thinking it would give me room to upgrade to binos in the future, but there is no way, unless I’m missing something for it to work. I’ve flipped the two sides and it’s either inside my eyeball, or too far away to use.

I feel like I have to be missing something since I see people running these units as binos.

Any help would be much appreciated!

First time hiking with Nightfox Prowl 2

Equipment:

Dual Nightfox Prowl 2 mounted on Fast Helmet, Uniquefire UF-H5 850nm IR flashlight as primary source of illumination at lowest setting to maximize battery.

CCW Glock 19 gen3 with Vitoinno VT-9054 Vis/IR combo Laser/Light aiming module

Garmin Forerunner 970 with Hike + GPS maps enabled

Please note: Compression of video is due to software, but the actual picture live in person is slightly more clearer and less laggy.

As a beginner, hiked a couple of paved and unpaved trails in an area above 10ft sea level for 2 hours in the dark for the very first time. I was low-key terrified, but 7 out of 10 would do it again with this digital setup.

Why can dedicated night vision sensors capture color in near-total darkness but phones can‘t?

Right: my phone, actively recording video (you can see the timer running), in a room this dark.
Left: the live output from a low-light color sensor we've been testing, same room, same moment.

The phone is genuinely trying to record — it's just too dark for it to capture anything usable. The sensor on the left is picking up full color detail in what's basically pitch black to the naked eye.

Not a staged comparison, this is just what real-time footage looks like from both devices side by side.

Prowl vs NVG40

I love the circular screen on these models, but I am well aware that they are just toys for airsoft....

Does anyone have experience with both? GNG shills say the sensor is better in the NVG40 which is the only thing it has over the prowl, at the cost of FOV.

If you just want to gush over the GNG2k or NVG30/50 instead, feel free. I will probably trade in down the road anyway.

Looking for toy grade/low end nvgs

im not sure if this is a great place to ask after reading a few posts, but i was thinking about getting low end Digital NVGS to mess around with, i dont plan to use these for any practical use besides fun with friends.

i got one of those old Cyclops goggles from 2009 at a garage sale and it was neat but i lost it a few years ago and there was a lot to be desired. However, im sure they have improved since then and im wondering if you guys have any recommendations under 100$ for me to look at.
