Just got an alpex lite, needs a torch and a mount.

Options are the nightblaster mini (the 50mm lense of the normal nightblaster i think is a bit large) maximum shooting distance 40m for me.

Nightfox XB5 low glow has 3 settings for low medium and high which i like the sound of.

Id like the 940 due to searching threads and reading up and most of my shooting is fairly close range and I should get a good imagine quality with the alpex with a 940.

My pondering is around batery life, and stealth. Id like to be stealthy for obvious reasons so would a dimable IR torch be better as I could get away with being on the lowest setting around farms and paddocks?

Has anyone had issues or experience with working around farms and using 940 on full power and it being too much or batery life being poor? Id like to get away with the minimum I can.

Seem to be plenty on the market from reputable sites and less reputable sites for under 50 quid.

Regards all, happy sunday!
 
I use a Uniquefire T20 torch in 940nm. It has three power settings and a focusable lens from flood to beam. The rechargeable 18650 battery life on a low power setting is very good and it has plenty of range available by tightening the beam or selecting a higher power setting.
They are readily available on eBay, either as part of a larger kit or just a basic torch.
 
Thanks that's helpfull for real world experinece with that set up. I had seen that torch but it looked extremely bulky with a 44mm head size. I guess you cant have it all though! Cheers
 
You need not worry about choosing 940nm over 850 nm. 940nm effectively halves the range as cameras are less sensitive to this wavelength. Scientists are certain that the eyes of rats and rabbits are not at all sensitive to red light let alone ir. Humans can not see ir either but we can notice the very small amount if visible red light that most leds emit. We tend to think of animals as reacting in the same way as we do but their senses work very differently and the quarry species that we hunt are prey animals and their senses are attuned to surviving so really very sensitive to sound, movement and scent.
The optimum ir torch will have adjustable power and focus which enables you to run at the lowest level of illumination which allows you to clearly identify your target and shoot accurately. It has become common for people wanting to record their shooting and they want better illumination for videos and far more light than is required just for shooting. The higher resolution of recently made digital scopes also requires more ir than would have been needed on an older unit with fewer pixels. At air rifle ranges most torches will be fine but once you start wanting to shoot at 100 yards plus then you do need better quality.
 
@Scubashot

I just went to order but I notice on the ebay link ot says there is 1 mode (high). How are you cycling through the power outputs?

Thanks for that input. @terry1001 as long as i can see 50 yards i think im happy. It would be nice to scan a field but at present im around farms and paddocks.

I have read some claiming that switching to 850 spooks quarry fairly rapidly.

My pard unit has quite a red glow emmited from the lense which i only noticed when i walked past a reflective tractor window and was suprised by the red glow. Its almost beam like to be honest if i point my gun at the floor i can see the red light projected.

Most torches change power level by a quick press on the on/off switch. Some will stay on that mode if switched off and left for a while before being turned on again, some don't which is a bit annoying. It depends on the driver circuit used, again some of these can be changed by soldering a link across a couple of terminals but unless you have the circuit diagram, which you won't get with a torch, it's near impossible. I used to buy the circuit boards and many could be altered.
I have been using IR torches for a long while and have made many plus the add on camera units and used to sell these from time to time. This became uneconomical as the Chinese started to produce them in large numbers. Some of their torches cost as much as a decent ir led bought from a reputable European supplier. These cheap torches claimed to use brand name led emitters but were of low quality so you might well get quite a lot of visible red from what is supposed to be ir. people wanted cheap kit and the way to do that easily is to use cheap (and nasty) parts.
As I said earlier I have been using ir torches for many years, in fact when I started there weren't commercial ones available for non military users so we had to convert our own. These were all 850nm units and I have never had a rat or rabbit spooked when being lit up with ir and even a red light is fine. White light is hit or miss but in an emergency will often give you a shot but it won't be very productive. The one thing that is guaranteed to spook any quarry is poor fieldcraft soas soon as you introduce sound, movement or new smells Mr Rat will be gone so shuffling about, smoking, noisy clothing, coughing or splashing on gallons of aftershave will kill your chances. Even moving around while scanning for targets generates noise. Being extra sensitive is whhat keeps these animals alive.
If you look back at an ir light source you can usually see a red glow which is noticeable if you are in line with a tightly zoomed beam, moving off to one side will make it virtually invisible and if the beam is zoomed out (and at low power) you probably won't see anything. However as I mentioned earlier cheap units may well have a lot more visible red light, if your Pard produces a beam which you can see on the floor that suggests it's a poor qualiity led being used. There are plenty of people on youtube posting rat shooting videos and I do watch a couple and have, in the past, watched many more and I have not seen instances of rats being spooked when illuminated but I shuld say that these have been experienced and competent shooters. Animals and birds seem to have different light sensitivity which I suppose has evolved according to their environment, woodpigeons apparently see ultra violet so can clearly see at a distance the white neck ring and wing bands of others. I have noticed that ducks and geese see red light and get upset if a red beam is swept over them, one place I shot rats was around a duck pond and the sleeping birds soon protested about a red light - I wasn't shooting the waterfowl just spotting for rat activity and I stopped that when I saw the effects.
You will find that many of these shooting accessories are being upsold to keep shooters buying as anything newer, different or shinier does cause many to reach for their wallets, it's peer pressure and the power of advertising.

I use my Pard with the T20 torch clipped to the scope. It extends the battery life of the Pard and gives me the choice of either the 850nm of the Pard or the 940nm of the torch.
I had read of the various scientific reports suggesting that rats etc don't see the 850nm wavelength, but also many regular hunters on here that disputed that. Certainly, looking at the 850nm Pard lamp, there is a big difference in the amount of visible red light emitted, compared the the tiny red spot produced by the 940nm torch.

I wouldn't bother with the extra hassle of the additional torch, mounts, batteries etc if I wasn't convinced. The 940nm set on medium power with a flood setting on the zoom works very well out to at least 25 yards, which is all I usually require.

Unfortunately, UniqueFire seem to have changed their power switch on the T-20 model to a single, max power only.
However, they have introduced the uf-2002 d940 model which replaces the original three setting switch with an infinitely variable dimmer type. I have only seen the 940nm version listed on AliExpress, although the 850nm version does appear on eBay. Hopefully the 940nm will also appear soon.
 
Thabyou both for your lengthy informative replies. I have ordered a 940 torch with a rotating dimmer switch under brand name ultrafire i think. Its not too large and has a smaller head rhan 40mm, will be trying it out over the next few weeks.

Thanks again
 
I prefer illuminators with variable power, simply as it does extend battery life and must reduce the chance of them associating that red dot with danger.
Most of mine are 850nm but I have recently purchased an XB5 Pro 940nm, but I've not had cause to use it. My standard fit is an XB5 850 as they seem a fair compromise of usability and price.
My maximum range is 40 yards to view, though I have lit up foxes further out to watch them.
