1. The Forum Rules have undergone some minor changes and updates.  Please take the time to read them; it will only take a couple of minutes of your time. By doing so, you lessen the chance of incurring the wrath of the moderation team or making yourself look foolish to other members.

    90% of users posting adverts in the Sales forums need to be reminded to read the rules as their posts are wrong.  This is unnecessarily time-consuming and will no longer happen - if your advert doesn't follow the Sales Rules it will be deleted and you'll have to start all over again.

Even if this is just your own personal opinion, RESPECT YOUR FELLOW MEMBERS.'

  3. Dear members,

    Our membership (like our country) consists of people from all walks of life; different in far more ways than can be listed here and each with a different view based on their experience of life - regardless of their colour, religion or cultural heritage. Every single person in the UK has been born of mixed race – we are a multi-coloured and multi-cultural country.

    As many of you are aware there are a handful of individuals amongst this membership that persist in making provocative, inflammatory, racist and otherwise offensive comments. This has been happening across the forum to a certain degree but is most especially prevalent in the Adult section.

    The moderation team has tried to stay on top of this, however unfortunately because of the ‘offensive’ nature of much of its content we don’t monitor the Adult section quite as much as perhaps we should. As a result much of this behaviour has gone unnoticed unless it has been reported to us. While the team always intended to take a "light touch" approach to the Adult section it would seem that some people aren’t quite adult enough to be left unmonitored after all.

    This behaviour is, and always has been against Forum Rules as well as the specific stipulations of the Adults forum and it will no longer be tolerated. We feel it's time to draw a line in the sand and as such from this point onward offenders will receive an immediate and permanent ban from the forum.

    In order for us to achieve our goal of restoring the forum to the friendly and tolerant place it once was, we ask that ALL members be mindful of the content they post and help us to stop unacceptable behaviour by using the 'Report' tool at the bottom of any offending post - the results of which can be seen only by Admin/Moderators.

    You should all receive a copy of this message by PM.

  5. Postings on Politics, Religion & Controversial Off-Topic Material

    The majority of users do not want to read about these subjects and people have left the forum as a result of it – this is after all an 'Airgun' Forum. It’s all very well to say they don’t have to read it if they don't want to, but as most of us use the ‘New Posts’ button there is no easy way to avoid it.

    All AGF staff members are in favour of people being able to discuss what they want, but we have to draw the line somewhere if it is upsetting other users. We don’t want to read about these topics either.

    IMPORTANT- The discussion of politics and religion is no longer allowed anywhere on the forum (including the Adult section).  The only exception is if it's airgun related - they must be put in the Airgun Related Politics section..

    We will not tolerate bullying or personal attacks, racism or any other offensive 'isms'. we will remove these topics from the forum, we will not give you an area where you can abuse each other. We will not hesitate to ban offenders.

    Having built and used a couple of NV scopes I found that one of the main problems when out shooting was having to swing the gun around looking for targets. Now I know that there are plenty of NV monoculars around starting from around £100 and going up to stupid prices, but this hobby is all about building the stuff yourself, so I had a go at building a spotting unit that I could easily scan around looking for targets before (hopefully) shooting them with the gun mounted NV .

    This is what I built

    NV spotter 1.jpg NVspotter 2.jpg NV spotter 3.jpg NV spotter 4.jpg NV spotter 5.jpg

    The camera is a Watec 902h from E Bay
    The lens is from Stock optics - VF-MI-8-50-C-MP and can be zoomed from 43 degrees in to 7 degrees (the view on the LCD is with the lens fully zoomed in to a 7 degree field of view)
    The 4.3 LCD screen is from E Bay (multiple sellers)
    The IR Illuminator is the same as I have on my gun mounted set up and is described in an earlier thread,(Osram Ostar IR LED) but basically it's an Osram Ostar IR LED, mounted to a machined aluminium block with a maglight lamp head housing an Ant Supplies 50mm aspheric lens
    I normally shoot rabbits, but was invited out for some fox shooting a few nights ago and asked to take the spotting unit with me.
    Everybody (especially me!) was impressed by how far this unit can see targets. Admittedly it was a clear night with almost a full moon, but we were picking up shootable eyeshine at easily 400 yards plus.
    Hope you like it and if anyone wants more info on the details of the build, please post your questions here or drop me a pm


    Cheers

    Bruce

    Well done Mealie, that osram looks so compact and tidy. Nice job, what battery are you using?. Im thinking of building the osram, as my 5mw utrafire is just eating batteries.

    edited, sorry just read the ostram thread in more detail and seen the battery spec, thanks

    With the lens fitted at the moment, I would say you could differentiate between a cat and a fox at 100yds.
    The LED is illuminating targets at over 400 yds, but you would need a longer lens to be able to differentiate between a cat and a fox at that range

    Cheers

    Hi, sorry to be a pain in the arse but could you put up a nice shopping list for all the part i'd need for this build, in particular the wiring components? I've built the torch body but I can't get my head around the wiring!
    I don't like to keep asking for advice without giving anything back but electronics isn't my thing, advice on ferretting, net making etc I can help with!
