Thread: Question - 850nm or 940nm IR torch?

Appreciate your time

NFT - can you describe this in more detail - what do you mean by "when you change the focus, the beam heads for the trees!!"? I'm considering a 940 addon for my HT-60 and this was the obvious choice. Thanks

I think he's talking about the adjustable focus on the built-in IR, so when it's focused into a tight beam it's not in line with the crosshairs.

I'll be reviewing a torch with a VCSEL chip which is providing 800+ meters of decent visibility with my Pard NV008 S

Hi CM et all,

Yes thats right, when you changed the zoom function on the supplied IR torch.... I'd avoid that like the plague IMHO - seen the same torches on AliExpress for $25.00 - I kid you not.

I did some research and sourced an IR laser from the UK.... think it cost me $220 landed - no border fees.
I can link what I purchased, bearing in mind this was also in 940nm - wondering if I should have just got the 850 and be done with - but heres me, trying to be sneak sneaky with 940... pfft!

Anyways, its a vast difference than the supplied unit. Still getting used to using the 66 - what comes into play as well, is the ability of ones scope to pass IR thru! Some have optic coatings to reject some IR, and I feel my Burris ones do... I digress...

Link for where I bought from ; think its a one-man band in Kent, UK.... and supposedly he make these up himself? Or some anyways..

Think given that when you change zoom ( zoom in ) with most illuminators, they dont always zoom into true centre - so the Adjustable Low Profile IR Mount ( @Night_Into_Day ) would be most beneficial!! https://www.nightvisionstore.co.uk/a...nt-c2x28623988

The VCSEL lasers just throw more light than LEDs further, though everyone to their own.


Still wondering if I should have gone with a dedicated NV unit as opposed to the add-on - oh well, it works and the hares have no clue what's hitting them - that's enough win for me!

Adjustable Low Profile IR Mount

@cmthelegend

May have found some cheap(ish) adjustable mounts - have ordered a handful and will trial and see how the go... Ex China of course... !

Can you drop a link here? I'm trying to source something cheaper for some adjustable focus IR models I'm considering to stock. I had previously considered the Convoy L21B (fixed beam), but you get too much glare when close to the ground since you can't focus the beam in.

I'm using a no so cheap Chinese sourced adjustable mount. Has been working well on the Pard NV008 to attach an external zoomie 940nm illuminator.

Thanks for all the info and links. That UK IR looks good. I went out and shot 31 bunnies on Thurs night with the standard HT-60 850nm and surprisingly, I don't think any of them were concerned about the light, which I assume is just a red dot in the distance in the same way we see it. So I'm going to persevere with what I have for now and focus more on accuracy and reduce the rounds per kill equation. I need to get a good bipod that is easy to use on the go.

Cheers
Cam

I'm actually starting to think that external illuminators aren't really needed when the built-in ones are sufficient at the ranges we're usually shooting at. The Pard 008 S (850NM) is quite happy out to 500-550m, so I'm not sure how great a demand is for something better.

Another part of the equation is how long do you want your NV scope to run on a single battery? Running the external IR, and turning off the inbuilt IR illuminator means I get a lot more hours before faffing with changing batteries in the Pard.

Over time rabbits learn what that small red light means, and run for the hills as soon as they see it. The 940nm illuminator just makes it easier.
I only bought the external illuminator, as the inbuilt was 850nm, and at the time there were no NV scopes that gave you the option. Things have definitely changed in that space.

I would still like to get a real 940nm laser illuminator, rather than the VCSEL one I currently have. More photons equates to sharper less grainy images, especially at range.

OK, so found these - I bought 5 in though freight killed me - seller wasn't kind in combining freight costs...
though fits the bill for movement to allow non-centralised beam to be centred at will.


Happy to flick off at cost - $50 plus post... like I say, freight was the wringer...

Pictures below - Sytong illuminator just for demo purposes to show 25mm ( 1 inch tube fitment)









Thoughts?

Just don't forget us users who use the Add-on type devices - the Sytong HT77 has no illuminator at all - at the cost of an LRF - so external illuminators are very much required!!

I'm having trouble understanding the point of the HT-77 not having an all-in-one like the NV008 S LRF from PARD. Some say they like the HT-77 to reduce the size, but then you're mounting a larger torch on the side or elsewhere, which is much larger than what's on the PARD. The HT-77 is an add-on though, so is it too much bulk mounted at the rear of the scope? I don't know much about NV, I only purchased the NV008 for the purpose of trying to find something decent to sell instead of believing others.

I'll be mostly closed next year, so perhaps I wait until 2024. I'll be open maybe 1 week every month.

It suits my needs - I for one, did not want to commit a rifle to Night duties only, though understand they can be used during the day as well - moreso that I can sight my rifles 17 HMR / 223 Rem / .22 etc and fit each scope with the attachment ring - and swap the one NV unit between them as necessary - hence my investment into the UK-sourced laser - not to mention I have variable high power scopes on these too for longer-range daytime home load varminting...
Carrying a larger torch is the least of my worries - LRF and changeability is what I wanted.

Everyone is different as to what they need in a device - though Im certain the dedicated units probably work just a little bit better than the Add-ons - Add-ons need a vari -Parallax scope ( looking at you Sytong )


As for extra bulk - yes there is some, but acceptable. Depending on the scope - move it forward in the rings, or move the rings forward - this then helps eye relief for when using the add on unit so its not too far back - its not perfect - lets be clear, but sure is fun when hares have no clue wtf is going on at night when their mates explode next to them.
