L3Harris PVS-31a VS ACT in Black DTNVS
HTML-код
- Опубликовано: 2 окт 2024
- One of the most common questions we get is L3Harris PVS-31a or ACT in Black DTNVS. We are firm believers that night vision is application driven. We never want to push customers on direction or another but rather give the community the education and tools to make an informed decision. In this video we go over the features of both the PVS-31a and the DTNVS with pros and cons to each system. No night vision system is perfect, they all have nuances that differ from one another.

I’ve had my DTNVS since June…literally the most badass thing I own. I put NV above full auto in terms of fun & coolness. Worth every penny.
@Dan Deller well I actually didn’t buy from these guys if you’re talking about this YT channel
Oh you just mean the housing itself? It’s been plenty for me! I baby them but they feel plenty sturdy.
I would go thin filmed bino's from Night Goggles with very small spots for $6 -7 grand for DNVG's or DTNVS's than $3,500 - $5,000 for just one night vision lense, PVS-14.
But if that's all you can afford, oh well.
The DTNVS is a carbon fill polymer which makes it substantially more rugged than the glass fill DTNVG. We would not say that ruggedness would be a concern on the DTNVS comparably in the world of electro optics. Feel free to call us with any questions. We are here to be a resource.
I mean full auto is free if you're handie.
The Taliban love them!!
This makes me want to cry..
🤣 but actually 🤬
@Emmanuel GoldsteinThose things arent cheap either. I've been looking at an ATN X-Sight for coyote hunting
Thanks Uncle Joe!
They don’t know how to service them or take care of them so they’re probably broken by now. Same thing with the tactical vehicles we had there. They’re all trash now bc they don’t know how to service them at all and don’t have the parts. So that money went to nothing
The DTNVS has an adapter for an external battery. It's way TF overpriced, but it works
from a guy who was dead set on getting 31A's i went with DTNVSes instead and I am completely happy. 31As are really for two kinds of people: active military and cloners. The 31D on the other hand is a whole nother beast... If I could of had the option to get a high spec 31D i would of got that instead of the DTNVS.
No manual gain is a huge downside of the DTNVSs
@@totenfurwotan4478 I don't really find it a huge issue personally...
@@Josh-wv3mn I’ve found most people just think it’s to adjust the contrast. Manual gain is extremely useful as it allows you to use the tubes AND retain your natural night vision. This allows your peripheral vision to still work which when using tubes with 40deg FOV that’s important when moving around wooded areas or structures. On a wide open range it’s a non issue, when you start trying to make complex movements at night you will realize how nice the peripheral vision is
@@totenfurwotan4478 my natural night vision is still retained even in areas where my DTNVS start auto gating from over brightness.
Looking through my nox 35 however will ruin my natural night vision. I think people over emphasize on things. Yeah it would be a nice feature to have but at the same time its just one less thing to mess with in a stressful environment. KISS
@@Josh-wv3mn as someone who has used DTNVSs there is zero chance you retain any natural night vision looking though those tubes. I’m talking all the time, not just when something auto gates your tubes. You literally can’t see anything around the tubes because they are so bright. It’s not some equation I need to calculate to turn my NODs up or down, it’s a big nob that is easily turned.
Got some PVS7's that I've had for years. Now thinking about getting a new pair and leaning towards the DTNVS.
The DTNVS is a great system 🤙🏼 HUGE improvement over what you’re used to.
Your mind will be blown by the difference
Are they affected by EMP? Would they require a Faraday cage for storage?
I am just not a big fan of 31s not turning off when you flip each pod up. That is a hard thing for me to get over
Good point, I don’t think he mentioned that about the 31’s.
I prefer my DTNVS over my 31As, you can get the best tubes out there hand selected for under 12k with DTNVS but for almost 14k with the 31s you can get 2300 fom and other low minimum specs. 2.5 ebi is the maximum ebi allowed and anything over 1.5 your nods are get effected seeing in the dark. Lower the ebi the better by the way. PVS 14 lens are high quality and were military standards for years.. I’m pretty sure quad nods use pvs14 style optic but I may be wrong.
GPNVG's use the same objective lenses as PVS-31a's.
We need a video on the Pvs-31-D. That’s an interesting housing I never hear much about.
We got it coming 😉
@@LicentiaArmsCo maybe the newer programmed Mawl C1 vs the older programmed divergence would be a cool video too.
Whats the difference between the 31 and 31D?
@@BeastHunterSam The PVS-31a is manufactured by L3Harris and uses L3 unfilmed 2376 min FOM white phosphor image intensifier tubes. The PVS-31d is manufactured by Elbit systems of America, and uses a variety of milspec Elbit thin-filmed tube options. They are entirely different systems with different feature sets. The PVS nomenclature is a military designation which is why they are close in name.
@@LicentiaArmsCo thanks for the reply, I'd love to see a comparison between those systems!
I love my DTNVS. It is possible to make the DTNVS as light as the PVS31As with RPO objective and eyelenses. It can also be adapted to a battery pack with JAG consulting's adapter.
DTNVS is a great system. However, while true, the battery pack adapter kills the ability to simultaneously have an onboard battery and the rpo PVS-14 glass is still inferior to the PVS-31a optics. The biggest feature that cannot be upgraded is manual gain. Manual gain is an extremely valuable tool. These points still don’t fully negate the benefits of 31s. Night vision is all pros and cons with all systems. Glad you love your goggles 🤙🏼
@@LicentiaArmsCo I guess what this means is I will have to own both at some point and decide which I enjoy more, lol.
@@LicentiaArmsCo also from what I have heard the DTNVS housing is marginally more durable than the PVS31A housing which ultimately was the deciding factor in my purchase but I could still be mistaken. My close friend through highschool was in 3/75 and issued the PVS31As, he said he saw a lot of them break during the line of duty
@@Jewifer333x2 if they were issued DTNVS they would break those too. ;)
@@twdunn9 lmao they sure would
What about the price of serviceing from L3 on the 31's outside of the warranty.
That would all depend on what exactly was being done with the unit.
In before “hOw mUcH dO tHeY cOsT” comments come through
haha lucky for them we have a stellar website with all the pricing they could want lol
The dtvns now comes in manual gain ? I can’t seem to find any info on that
Kinetic Consulting likes his DTNVS's over PVS31's. That's all that needs to be said.
He was also involved in the design process for DTNVS.
No manual gain is all I need to know. Just wish the 31A would turn off when rotated up
@@totenfurwotan4478 I guess it’s a give and take. I feel the PVS31’s are more for the advanced users and may require a bit more training.
Or you could go the route of the 1431 mk2 system with Elbit or L3 tubes…. The darkhorse of bnvd.
I’ve only used 31a’s (between these 2, I’ve used some prior tech before the pvs31a) in ranger bat. Never used NV in civ life. Would love to. Can’t justify the purchase just yet lol
Can you wear prescription glasses with NVGs?
Yes, you just need to focus the ocular adjustment while wearing your corrective lenses.
I know you can’t but it would be so cool to see inside of L3’s factory!
I opted for the 1531s to go with my DTNVS unit. Adjustable diopters and pvs 14 components was a no brainer for me. Sometimes I shoot with the 1531s and sometimes the DTNVS. Can’t go wrong with either set. The simplicity of the DTNVS is kinda nice. One simple pvs 14 style knob as opposed to a push button power/programming setup. I’ll never use any of the settings you can program the 1531 to do but that’s just me. One thing I wish the DTNVS had was a remote battery port in the unit itself so I could go back and forth between goggles using my pack without buying adapters but it is what it is.
Allegedly the adapter for the DTNVS they sell will take L3 battery packs
@@Jewifer333x2 indeed they do. Probably gonna run the AB night vision pack. I like the fact you can use AA or 123s!
Thank god you made this vid
Glad you found it useful 🤙🏼
POV: you came hoping to see some cool footage of nods at night 😔😔
As a poor I would agree deez both some very guud boyo’s
Great video. I’m definitely interested
What’s the difference between the white phosphorus versus the aviation grade?
aviation grade is simply a spot spec and doesn't affect the color of the tube. Both of these units in the configurations we offer are white phosphor.
Whats the 31s wrap?
Will the 31A tubes individually turn off, if they are rotated out to the side?
They will not. However, DTNVS will.
My 31’s turn off when stowed individually
@@Tragic387 the only PVS-31 variant that has independent pod shutoff is the PVS-31d. The PVS-3d is the Elbit goggle and is a completely different system than the L3Harris PVS-31a.
@@LicentiaArmsCo you know, I thought of this the other day during my use and realized I was wrong. I could’ve swore they did, but they definitely don’t
Can you tell me which ranger band size are you using in front lenses to hold bikini covers? 31s come with just one in the back :(
We just snag the variety pack on amazon and use the ones that fit.
DTNVS > pvs31. Aib are 17 oz. So the same but the cr123 lasts 22+hrs w/o a battery pack. Why have a battery pack. More shit to snag & break. Don’t need manual gain bc ur constantly fiddling w it.
The pvs-31 are not any better in any way for me.
DTNVS can have "manual manual gain" via iris diy in the butler creeks
Going that route simply cuts light transmission and increases noise. Apertures are really designed to increase focal distance and not replace a manual gain control. You will get a substantially better image with using manual gain to decrease brightness over an aperture. But they can be used to dim the image, just not ideal.
Thr DTNVS can accept a battery back. Or am I mistaken?
It requires a DICC or TSC adapter for the battery cover first, but you are not mistaken.
Nice video!!!!
I feel like manual gain isn't all that important if you have adjustable focusing devices. If the environment is too bright I'd rather use my tarsiers since that way I also get better focus.
It is all personal preference. However, keep in mind that apertures increase noise and do not replace manual gain. They will cut light transmission, however, it is not the same dynamic control that manual gain provides. manual gain can increase the crispness of an image. Apertures simply cut light and increase noise.
It’s super important. It’s the difference between having peripheral vision under the NODs which allows you to read lighting conditions and navigate better. Very rarely is it “pitch black” out where you have no vision at night. Manual gain allows you to see through the NODs and still be able to look around and under them. Auto gain is alway way to bright and the only thing you can see is through the NODs
@@totenfurwotan4478 that's laughably incorrect. Have you ever used an automatic gain unit?
@@LordPerique yes I have both. I have 1531s AND DTNVSs. Auto gain units are ALWAYS too bright to retain your “normal night vision” while using them. Manual gain allows you to dim the brightness enough that you can use ambient light around you to see your surroundings with your natural night vision while also being able to look through the tubes and get that benefit as well. Manual gain has NOTHING to do with focusing the tubes, it controls the brightness. When licentia arms talks about “making the image crisper” they mean it cuts down on the tubes scintillation, not that it changes the depth your tubes are focused at.
@@totenfurwotan4478 I don’t know what people don’t understand about this. I guess they’ve never had to stumble through the woods at night with their night vision ironically wiping out their night vision.
Website is slick!
