Looks good Steve, will be interested to see what range you get :good:

 

From the video it is hard to see the screen or light from it. Is it bright? Will the quarry see the light from the screen much?

 

ATB Steve

 

its easy to see, doubt it will scare the rabbits, as when lamping from the 4x4 I normally leave sidelights on, so with this set up, Ill park up and sit in darkness, doubt the screen will even get noticed by them, we shall see though

You will find with using a large lamp with ir filter on it ,that the rabbits and foxes will get spooked by the light,as you will be flooding the area with ir.

Try and get a small ir laser and you will be amazed at the clarity you will be able to achive.

 

Or get a dimmer switch and keep it as low as you can,all you need is enough light to spot bunnys eyes which will glow from a long way out.

 

Good luck,would be good to see it used in the field. :good:

How will the foxes and rabbits be spooked by IR 'light'? It's invisible. The only thing they might see, is a dull red glow from the filter, and that should'nt bother them. I know, as I used to use this method of vermin control.

I used to use a light with filter material over it years ago and it was pretty clear the bunnies could see something going by the way they legged it when I switched it on.

Strange that, because when I used my Blazerlite lamp with dedicated IR filter, nothing would see any IR 'light'

The other night, while using my NiteSite NS200, we were watching a hedgehog ambling across the field, no more than 15 yards from us, and totally oblivious to the IR light 'shining' on it.

same as steve b has said, can rabbits/foxes see IR light :hmm: as Ive used this lamp and filter alongside a mono hand held nv in the past, and they have been totally oblivous to me being there, a small laser may be got in the future, but it'll cost more than this has cost to put together, which I cant justify, so its the lamp for now

 

 

I dimmer would be a good idea for close up ratting action with an airgun, have been working on my new project "The NV mk2", this little baby is the mutz nutz................. :good:

your contraptions always look better than mine pat :lol::good:

depends what DN is was, you can see a red glow from the thinner size, mine is totally black, in the video Im holding the lamp in front/above the lcd screen, any light from the lamp, would have been detected on the screen/rifle/scope etc,

maybe it was your aftershave :D

Same here Steve, i use both ir laser N1000 and a 170 L/Force with a home made 850mn filter and the 170 wins hands down it just doesn't seem to spook the quarry as much as the ir laser, the other advantage with the 170 is the wide FOV :good: Downside is size but 99% of my shooting is done off the top of my 4x4 so not a problem.

 

 

 

 

 

no furry toys were harmed in the making of this video.

full description in general shooting matters

 

Sorry stubby forgot to say well done on the home made NV :good:

It's usually down to how efficient the filter you are using,some filter everything , but a lot will still let some of the spectrum through,and that's what spooks,I first noticed it on my lamp I used to use with an nv add on,the first filter I bought was a cheap one and I had a lot of jumpy rabbits and foxes,when I thought I had lost it I bought a new one from the gun shop and this was better,but still had a few rabbits that would not sit still when trying to get a shot on them..And unless your filter seals onto the light you will get a faint halo effect around the edge of the filter where it fits onto the lamp,and rabbits and foxes notice it.

I now use a dedicated nv and a laser, and I don't get any spooked..

as stated in my post above, this is all down to the ND (nuetral density) of the filter, Ive yet to see a ir filter made for shooting to advertise its ND number, it can be from 720 upto around 960, camera filters do give this info, as do ir sheet (cut your own) so troubles you had with shop bought lamp filters, may only apply to you, or others following the same lines, most homebrew makers do not want to go to the expense of shop bought nv filters, and therefore make their own from either sheet material (like myself) or camera filters, thus using a higher ND and not having the problems you describe

I agree with this I cut my filter from a sheet with a ND of 962, the only way to tell if the lamp is working is to 'shine' it on your hand to see if you can feel heat. I cannot see any light at all through the filter. At first I thought my lamp was broke untill i felt the heat coming from it.

Sorry mate didn't see your reply, was replying to steve and skip read the rest :blush: I agree that the problem will be with filters that are bought as you have no control over how they are made,and as I found out cheap is not always best.

ok, had my first test run over the farm last night, noticed straight away a few bits that need tweaking, but these are not associated with the nv, firstly I have a rifle rest permantly fixed to my 4x4 door, of course its set up for leaning out window to look through a scope, therefore using the nv, the screen was too high to be comfortable, I'll need to make up a 2nd rifle rest if using this in future, my lamp worked brilliant with the nv filter, too good in fact, could do with a dimmer or sorts

my idea of an extra larger lcd screen mounted on centre of dash is deffo on the cards, as this would make viewing better for everyone, inc the shooter/me,

I can also appreciate why everyone say's get paralex with side wheel, having to reach forward to front was a pain

and I need to tweak the nv were it slips over end of tele tube, plastic tubing is ok, but some sort of rubber should hold the crosshairs in centre of screen better, last night in was slightly to bottom of screen

 

ok, thats the tweaking covered, so how did it fare,

brilliantly, straight away I was viewing rabbits playing at around 65yds which normally would have scarpered, I did'nt shoot these as its near a public footpath visited by dog walkers, but it showed it worked, they were totally unaware of us being there, even though the car was "running" and I had sidelights on :good:

 

my first field and I quickly spotted a feeding rabbit, had I being using the lamp he certainly would have been ready to run, but with nv, he carried on eating, bad news, one dead bunny, my last moan would be distance is hard to work out, I thought he was a good 40yds, yet it was only 20, so I can see this getting used more in areas where I can stay/sit and know a set distance where rabbits come out, a friends garden for instance is plagued by rabbits that only come from one entry point/area, sitting at the picnic table this nv would be ideal, but for driving around the farm Im saying lamping is better

 

Im happy that it works, and for £52.50, I'll continue to tweak it with the extra screen

also, the noise/click from the ruger in no way bothered any rabbits, I'll certainly be using it in future on the lamp

push bike inner tube over your scope does the trick.............

after sourcing an inner tube, realised it was my dodgy use of the electrical tape :lol: I had stuck the camera to the lens cap with cushioned double sided tape, before wrapping it all in black tape, I must of pulled the camera out of alingment by a gnats whisker, so I cut the camera off the unit and started again, being a bit more careful this time

 

sorted :good:

centred crosshairs

distance is hard to work out, I thought he was a good 40yds, yet it was only 20

 

Could you strap a laser range finder to it?

 

probably could, but it would increase prices, a friend thought maybe a normal laser, sighted in at 60yds to centre crosshairs, at least then you'd know if its closer or further,

 

alternativly, those using a side focus wheel would be able to see the focusble distance easier than I could,

 

or failing that, learn the distances on all areas before hand, easier in fixed positions rather than mobile

have just won a Vivitar DVR 20G HDD on evil bay, so now will be able to record my outings with the NV, plus after chatting to others on the hunting life, Im going to fit 2 x infra red spot lamps to the roof of 4x4, save having lasers or lamps on the rifle :good:

The best way to judge distances with NV I have found is remember how big a rabbit is in your scope at a known distance and then if the rabbit is bigger its closer if smaller further away. This works really well if you are keeping your shots under 100 yards, anything over and it gets ever harder to judge the distance :lol:
