  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.

Pard Nv007 Problem

    Funnily enough....

    tonight a Rimfire shooting friend called around to borrow my Pard 007 for his cz455 .17hmr / 6-24x50 endurance rig...
    he’s buying a 007 and I said he could use mine for weekend to get a taster...

    I know his scope would benefit from an infra red add-on torch... because it’s quite high mag...6-24

    I had an identical scope and it was a little pixelated using the on board pard IR so I set him up with a dark engine illuminator.

    earlier this week, following @mealiejimmie advice, I removed the diffuser from my 2019 pard 007... and the improvement in IR brightness is staggering!

    tonight surprised me hugely... we took the rifle over to the farm gate in pitch dark (yes...distancing and face snoods used!!)

    and scanned the lakeside 140 yards away.

    my mate commented that the pard onboard IR was better than the large 50mm dark engine illuminator...

    I chuckled and said he must have it lined up wrong... it will be much brighter than the 007 ir

    I took his rifle and looked through the scope... switched on the dark engine... then switched on the pard IR (minus diffuser...)

    I was amazed to see for myself that the little pard onboard ir laser is indeed MUCH brighter than the dark engine!!!

    both were fully focussed to tight spot beam...

    the pard IR now blows the much bigger IR torch out of the water!!!

    it was so powerful I had to reduce the laser lens focus or it was whiting out the pards view

    removing the diffuser from the emitter has transformed the inbuilt IR completely!

    no more bulky IR torch needed for 150+ yard use!

    Bellissima. Non capisco una cosa però. Cos'è la rimozione degli altoparlanti? Come si fa a farlo? Perché lo migliora? Scusate ragazzi ma la traduzione dall'inglese all'italiano a volte non funziona bene e sono nei guai. Nel frattempo vi ringrazio tutti. Tu sei prezioso

    Thank you very much friend! So you have to remove that little transparent square that you pointed out with the arrow? Because they put it if taking it off makes more luc

    Guys, has anyone found a way to make 18650 batteries last longer? To me it ends in 2 hours. Even less. Can't there be a way to feed the Pard from the outside?

    through the micro usb port can not be powered? When I connect it to the computer, the red LED lights up even if Pard is off. Seems like power flow or data flows?

    Charging the PARD with external power (which is what you'd be doing unless I've misunderstood) is warned against in the manual isn't it? :confused:

    You can power the PARD through the USB port, but take the battery out first.
    Frankly, using an external battery is just a PITA.
    It's simpler to buy a few decent batteries and carry a couple of fully charged spares with you when you go out.
    Also, USE THE SLEEP FUNCTIOJN when you are not about to shoot.
    A short press on the power button shuts down the camera and the IR to save battery power.
    Another short press on the power button immediately powers them back on again.

    Cheers

    Bruce

    A related question for you Bruce @mealiejimmie

    You can burn through a decent battery in a couple of hours with onboard IR

    So how come using a seperate T20 instead can yield so much more than double the usable time?
    I regularly go over 6 hours runtime with this set up so is the pard IR illuminator particularly inefficient do you think?

    I think it's because the battery indicator shows low voltage much sooner than it should, and it switches itself off sooner than it should.
    I've done power measurements on an 007, 2 x 008s and an 008 LRF (all old models) including the voltage at which the number of bars on the battery indicator changes, then changes to the orange warning and then when it switches it self off because it thinks the battery is too low
    I used a variable voltage bench power supply and this is what I found when I tested the 008LRF
    The battery indicator changes from full to 2 bars at 4.00 volts
    From 2 bars to one bar at 3.70 volts
    From 1 bar to orange low battery indicator at 3.55 volts
    It switches itself off at 3.40 volts
    Bear in mind that a fully charged 18650 is approx 4.1 - 4.2 volts, the nominal voltage of an 18650 is 3.7 volts and the minimum voltage that an 18650 should be operated at is around 3 volts.
    For me, the PARD is too conservative in it's battery warning and low voltage shut off, and changing those values would lead to longer run times
    T 20 torches don't have any low battery voltage detection (unless a protected battery is used, when it's inside the battery) and will continue to pull power out of the battery as long as the battery can provide sufficient current to the driver to put the specified current into the LED or vcsel.
    That results in more power being drawn out of the T20 battery than the PARD battery. so it lasts longer.
    Pull a flat battery from a T20 and the battery voltage will be less than 3 volts

    Cheers

    Bruce
