    Hi guys, I'm pretty much new to airgun shooting so wondering if the Combro Chrono is a good buy compared to the more expensive Skan's and the likes. Any info would be appreciated..cheers.

    Always found accuracy of the Combro more than acceptable and very portable

    I had one, use new good battery's in it & watch the lighting at times. Good things they are.

    Having read your previous post I think you have had it explained, you cannot possibly know what the exact fps your rifle is running at, and unless this is known you cannot know if the chronographs
    you are using are 100% accurate, Any of them!,
    The chronoscopes we buy are mainly used to check and ensure we keep to the 12 foot pound limit in the UK, and as most of us run our rifles at just over 11 foot pounds one percent accuracy is acceptable, granted some chronographs may be more accurate and this will usually be reflected in the price but not always,
    The Combro is one of the most affordable on the market and sells in the UK for about £50, it is accurate enough for most peoples needs and is small enough to carry in your gunbag so whats not to like

    1% if I set correction value to zero. But if I enter correct value from manufacturer it will shows me 232m/s instead of 240m/s, so error will be ~3%. And you can accidentally set your velocity over limit.

    I compared 4 chronoscopes at shooting range, so 3 of them showed the same velocity, but combro lower.

    Agreed. But my current chronoscope is small too, it can be used outdoor without any light issue (closed tube), it shows correct velocity, it can export log data to PC or my smartphone and its price just ~30GBP. Here is a video how it works

    No, it was just test shots from a pen, paper sheets and my breath :D

    I posted the real log some days ago here LG110 accuracy and it was made with export function of my chronoscope

    This chrono shows velocity in m/s. So 5-6 m/s is really possible from a pen
