I have a big wolf eyes that runs on rechargeable 18650 batts. I think I get about 200 m of effective range out of it. I shall try it again next week when I go bush and I will let u know

There seems to be 2 different kinds of IR, one LED and one laser. Is this correct?

And apparently you need 850nm and not 940nm for digital night vision https://youtu.be/oKwiWIFVsck

I’ve got a cheapie, called the ST67. The bloke that sold me the Pard included it in the package.
Seems to be adequate out to maybe 150-175m
Think Night Hunters sell them as well. Interchangeable lenses.

From my reading there are two commercially available wavelengths. 850nm and 940nm.

I'm gonna go off on a tangent here.. If its Radio waves, IR, Visible light, Microwaves, Gamma waves etc.. its all the same. Its Electromagnetic Radiation.
It's the frequency that changes the properties ( 850nm is a higher frequency than 940nm).

Red light is in the lowest part of the visible light spectrum, that explains how sticking a red filter on a torch spooks the critters less but also allows us to see less.

850nm illuminators are a good compromise for hunters, it's a balance between human optical vision and nervous critter disturbance.

You can go lower in the spectrum ie. 940nm and cause no disturbance at all, the trade off being that you see a lot less.


If a being looks onto the illuminator of a 850nm, they see a faint glow. If a being looks into a 940nm they see nothing, hence why this frequency is favoured by the military. The trade off being, us hunters lose a lot of visibility.
What I read is, if your target are armed and are looking for your location, prol better to go for the 940nM...




If you're shooting rabbits, go the 850. :thumbsup:

Thanks, xdom. Here's a visual representation of where IR sits

850nm does seem to be the sweet spot for digital NV, whereas apparently the 940nm suits the photocathodes Gen 3+

"saving money on an illuminator is the worst mistake you can make". These guys suggest getting a cheaper NV scope rather than a cheaper illuminator.
https://youtu.be/dL3j1tDnqQw

Oddly, they say for digital NV a 915nm or 940nm is best. WTF? I thought 850nm was best for digital?

Apparently you also MUST have a focussing torch.

Beam adjustment is also a nice-to-have for longer distance shooters

Is there any way to compare one IR Illuminator to another? Some parameters so you can say one is more powerful than another? Or worth more than another?

Good question. I’ve never seen or taken notice of any parameters on IR illuminators.
If it’s anything like regular torches any specs would have to be taken with a grain of salt.

When you see a $200 Olight torch advertised at 1000 lumens and a $29 EBay torch advertising 4000 lumens, you have to think that the eBay torch is taking liberties in its description!

I guess the only real way is either personally comparing them which is difficult or take other posters words on different models.

As for that comment about 940nm being the best for hunting, I don’t know what to say about that.
As I said before, anything I know about this topic is from reading stuff on the internet as opposed to using in the real world!
There’s plenty of articles on 850nm vs 940nm ( not just for hunting but for all the other IR uses ). They seem to suggest as I stated before. 850 gives you more visibility but 940 hides the location of the IR source.

The thing is I've seen videos where the 940nm is barely visible on a digital NV scope, whereas the 850 works fine. Who to believe?
