Chronographs

Another vote for the skan for an extra £50. Have used one out to 45 yards with a protection guard in front, although I never did hit it.

You could use an old mobile as target cam and connect it with a tablet or phone using the alfred app for android. Not sure if they do it for apple phones.

The get thick poly carbonate to protect the chrono display if using something like the chrony type chrono's.

Mark, Combro service is outstanding (speak from 3 times personal knowledge . The latest was about 6 months ago...)

I bought a chrony, it's very good but just gives you velocity- you have to do the rest. Okay downrange but the fiddle of setting up so you get a shot in the right place will send you to an asylum

So as long as it's working I always use the combro!

Hope all is well long time no see.

Hi old chum! Hope you're doing well down in the countryside. By Chrony do you mean the LMBR2? You're quite right about the Combros they are great, but another thing I don't like about them is having to elastic band the thing onto the end of the barrel. It works well with my HW100 but is a pita for the HW97 ...

All well down here in the Duchy thanks!

Combro's and break barrels are problematic. That's when I shot mine (twice ) The problem occurs when you close the barrel... Don't ask me how I know

Hi All

Well, I reckon it's horses for courses. I have a SKAN, Chrony F1 and a Combro of which the F1 and Combro are the workhorses selected for ease of use in the application at hand! The Skan is used as a useful cross check but can only really be used close to the muzzle and with care.

The F1 is the main workhorse for MV measurements and string comparisons for MV consistency tests and pellet comparisons and can be used downrange (although not too far) and with my home built illumination source mounted on the sky screens; is readily usable under fluorescent lighting. This has worked well for over 12 years with only one pellet impact incident (which was non-fatal!).

The Combro is barrel mounted but using a special adaptor made to support the Combro through the sensor shield mouldings and attach to the muzzle via a standard screw thread interface for which individual special adaptors can be made for each special (non-screw-cut) barrels. This grew out of the requirement to measure both pellet exit times AND MV for the same shot whilst undertaking rifle dynamics experiments and Robin was kind enough to suggest to me the optimum take off point for the first sensor signal (the only supplier prepared to do this so a big thank you for that as it saved me the task of reverse engineering the unit(s) to determine the tap off point myself!). This has worked happily for about 10 years and ever so many tests without incident. Before this, a separate "light gate" was used for exit detection and the F1 for MV!

It's all great fun isn't it!

atvb and stay safe and well.
