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.

  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.

    I have the 'Beta' chrono and its a good bit of kit. Good build quality, will do far more things than I want it to, but all in all I have been really pleased with it. I gave £138 or there about for it, two years ago. Shame your not somewhat closer, you would be welcome to use it.

    Many of the members on here rave about some of the chrono's that you see on the 'bay' for around £40. So I would take a look at those were I shopping again. KB1

    The one I think you are referring to is the Combro Mk 4 which I also have. It is fine for PCP but if you had a pretty twangy springer or rammer, or wanted to check a pistol or two you would be better going for something that doesn't have to attach to a barrel.

    That's correct. I have just looked on the bay, and there are some 'Alpha' and 'Beta' chrony's going for under £80. They have come right down in price assuming these are new. KB1

    The search function is your friend ;)

    In short, the Combros are a cheap (£55) option and work well enough for casual testing; however they do have their limitations (don't work too well on CO2 guns and springers if inadiquately restrained) and have to be reset after every shot unless you're using a serial / USB PC connection.

    Shooting Chrony F1 / Alpha / Beta models represent a good middle of the road option (£99+); resetting after every shot and allowing the unit to be used at range - opening up all manner of possibilities regarding measurement of velocity at distance; as well as being more friendly towards CO2 and spring guns. I have a number of these - they're great when the light is good, but don't like being used indoors / under fluorescent or LED light. In addition the sensor area is only about 1" wide; so they can be frustrating to use at ranges where the rifle's accuracy is starting to tail off. The units are compact; packing down neatly into their original cardboard box which is maybe 2.5 x 3.5 x 8".

    The F1 is the basic model and will record a string of 32 shots; the Alpha and Beta models add to this feature set (avg, std. dev etc) however I usually just write down the raw data and leave the post-processing in Excel to work out all the information I require from the shot-strings - so the cheaper, basic model suits me fine.

    The daddy is the Skan Chrony - these are around £200+, are self-calibrating and have their own light source; so can be used pretty much anywhere and are very reliable in my experience. They may also have a larger "detection area" however I've not tested this. When assembled they're more compact than the Alpha with their sky-screens, however they don't pack down and require their own (off-unit) 12v power source; not a problem at home with a transformer running off the mains, but a bit of a pain if using in the field (I'd probably lash up a battery holder for 8 x NiMH AAs if I had one).

    :)

    Pro chrono digital for me had this one two months now and in my opinion a fantastic bit of kit.
    Also this week checked it with two skans and its spot on, very happy.

    I have a F1 Chrony, with printer and I was pleased with it until I found out that it really sensitive in its readouts - as well as sensitive to light as Cloverleaf has already mentioned.

    Thanks to the Airgun Centre they have run 5 mags worth of my HW100KT over their skan and they came out with totally different results than I did....so now I have the numbers from AGC I am working with my Chrony to see how best to set things up to get the consistent results.

    I haven't quite given up on the F1 yet, but I can feel a Skan would be a worthwhile investment.

    I also have the Combro - but recently its been given be @bad@ errors, so waiting for some new batteries so see if that cures it...

    Thanks
    Tim
