Someone informed me that the military manual on setting focus stop rings calls for you to set the ring slightly behind infinity. The reason for this may be that temperature changes can alter where your infinite focus is. So if you notice it seems like it’s changing over time it could be due to temperature. For now I’m going to leave mine set at the perfect infinite focus that I currently have them at. When the nights start getting colder I’ll be able to see if my infinite focus has changed.

Good shit! Would be very interested in more. That Focus stop is very helpful! :)

Amazing how the basics are overlooked and just “assumed” that many know these things.

This was damn informative!

Good stuff on the diopter white dot tips, but how do you know where is the real 0 is at? I mean what is the easiest way to tell

I wouldn’t move your stop rings either, they are set where they are so you can attach magnifiers to the objective lens and focus them in, reason I wouldn’t move them is it can warp the end of the of the tube, it will cause friction in the focus adjustments and as you screw that tightening ring higher up on the pod you are tensioning it down to thinner weaker polymer areas, also the set screws are super super easy to over torque and you will destroy the threads. I already made a comment on the diopter lenses, don’t move the white dot ⚪️. The dial the numbers are printed on moves freely by hand... the white dot is your “zero” or reference point. So if you have 20/20 vision you would turn the dial until -.05 is in line with the white dot. A lot of people don’t know the rear eye cup insert are removable and are only there for sacrificial lenses or amber filters or filters of any kind. I don’t run rear eye cup inserts, it makes the IpD much easier because of the bigger eye box. So that was solid information. I’ve never broken a rear lens before, I’ve only broken front lenses and the actual arms the pods connect too.

Try the tarsier eclipse iris attachment you might like it better

The range of visual acuity of average people begins at -4. Most professionally tuned night vision will have a base setting of -4.

FYI 20/20 vision you would have your diopter set to -5

I use Matbock Eclipse on my NVG's, they devices work amazing for infinite focus!

THANK YOU!!!! you helped me adjust all the OCD issues i had with all my NVG's! All my dots are in 1 position and match across all my devices now!! 😎👍

I took off the eye piece trim ring and then immediately proceeded to break the threads on the back of the eyepiece Those trim rings protect the very thin plastic threads on the eye piece It's literally paper thin plastic and will break if you bump it into a hard object without the sacrificial ring/rubber boot trim ring thing installed

You could always do the 556 mod with some bikini covers

I wish you put more details in the title.

hahaha yes! thank you for this

What size are the set screws in the DTNVS?

Umm you don’t have to disassemble the eye piece to move it to zero... the ring turns without any tools. So if you are in -2 all you would have to do is grab the part of the eye piece with the serrations and turn it by hand to the 0. Do not take your lock ring off to adjust the diopter, they literally turn by hand without any tools or disassembling

thanks for this

Scratchy low voice, couldnt really hear him.

hahaha yes! thank you for this
