Thread: Night vision. Silly question

    Night vision. Silly question

    Hi, I'm toying with the idea of investing in night vision.
    Is digital in a completely different category to gen1, 1+, 2 etc..?
    If so what's the difference? are they better of worse than the above or the same thing but different?
    Like I said it's probably a daft question.
    Cheers

    Not a daft question. Digital is completely different technology - that came along much later.

    Gen'x' is a reference to levels of semiconductor technology in the creation of image intensifiers (tubes) and the advances in light gathering as a result. To give you an idea, Gen 2 has a gain improvement of about 10,000x that of Gen1.
    Doesn't make Gen1 bad - just means you need more (IR) light to get it to the same performance.

    Gen 3 is a further extension. BUT - these Gens are US standards. European Gen 2+ has equal capability of US Gen3, but because of the classifications, can't be called Gen 3 - you can read about this on the net if you're interested.

    Digital does not classify in this way, because the technology is totally different. Minefield? Oh hell yes.

    What I would do is look for some comparables - lpmm (lines per mm) is a good one - 64-72 is the rough benchmark right now. You can look at lux figures - to see how little light a unit needs - and you can look at FoM (Figure of Merit) - which is a sort of convoluted index where the greater the number the better the light gain.

    Better or worse - that's like asking for the best calibre on here....!! I would say you can spend whatever budget you have and get some form of NV - so I would look at use and capability v price and see if that helps you weed some out. I could go on, but I think I've answered your question. Feel free to ask more questions either in open forum or via PM....
    Nooooooooooooobody expects the Spanish Inquisition!! Our main weapon is.........

    Bear in mind that the image intensifier types can be damaged by exposure to bright light.
    Digital doesn't seem to suffer from that as badly.
    "Don't say I didnae warn ye !"

    A big thanks.
    I think that's cleared that up 4 me.
    All I have to do no is to put my hand in my pocket (& not in a mucky way)
    cheers

    To ad to the confusion. Digital tends to need more if than tube. The images are different and some people don't like the black and white I age of digital.
    in brief I still think tubed is better than digital but digital has come along in leaps and bounds.

    a better question now maybe,
    I have x amount of to spend on an nightvision device. I want to use it to shoot y animals at Z range. What do you recommend to do the job?
    I can speak in-depth and with great knowledge about most subjects until some bugger who actually knows what he is speaking about opens his gob .

    Always go and look through someone else's before buying if you possibly can. These things are incredibly difficult to describe.
    I have one of the original Ward-D-Vision digital add-ons. By standards of some of the gizmos that you can buy it is rubbish. However, I have it on a cheap Hawk Sidewinder scope mounted on my Tikka 22/250 and it kills foxes out to 200 yards. It's fiddly to use and I frequently cuss it. But at 600 and the second-hand scope for 110 I am not going to complain too much.
    Hell, it does the job I want it to do so that's OK.

    Hi Gnu,

    Tubed devices amplify available light in varying degrees and varying levels of clarity from Gen1 - Gen2 - Gen2+3 types.

    Digital is a technology that is sensitive to infra red light.

    Tubed benefits from additional IR, whereas with digital it's pretty much mandatory and the more the better.

    In terms of our civvi use of NV where using some IR is not the end of the world then the abilities of both technologies start to get on par.

    To put that into perspective when I'm out shooting there isn't really much that my top of the line tubed dedicated rifle scopes costing around 3500 can do, that can't be done with the new Ward D Vision 700 digital night vision add on at 695!

    Plus I only need one Ward D vision and not 2 or 3 dedicated NV rifle scopes.


    Cheers

    Then there's Daves (some bloke on nv forum) scopeless digital that needs very little ir, and comes either complete or just parts to build yourself. In fact just building one now for the .17hmr.

    Okay. I want to be able to shoot rabbits out to about 150 yards max and that'll be it's main use. It'll also be useful if at the same time, there's the capability to shoot foxes which are a bit further. The rifle I'm going to use has a low spec 3-9X40 on at present, so I don't mind ditching that and either getting a medium quality scope and an add on, or a dedicated night scope, although one with day capability would be ideal. My budget as it stands is about 500, but it could stretch further, but that would take time. I appreciate a reasonable normal scope would eat up most of that 500 or even more before I even thought of an add on. What are my options?

    wow its all a bit of a head f##k.
    recommendations please.
    was looking at photon xt got 800 ish to spend
    primary use would be for for bunnies with .22lr out to arguably 100 yrds. my foxes at the mo don't seem too adverse to a bit of light.
    thanks all.
