hi does anybody know if the chrono combro mk4 will work on underleaver air rifles i have a bsa superstar mk1.thanks

[MattyBoy]

Indeed it can

Just make sure you line the aperture up very carefully and keep hold of the combro when firing.

I have only shot my combro a few times doing this

As above,
You can, but its fidly. I found using insulating/electrical tap or a lot if rubber bands helps keep it in place while you load. But keep a hold whilst firing (Carefully!) as they tend to bounce.

You could of course save yourself a lot of hassel and get something along the lines of an F1 Chrony a little over double the price of the combro but no elastic bands needed and its very versatile being able to use it with any gun/rifle you may ever own and of course if you wanted to measure the terminal velocity at 30 mtrs or further you can.

I would have thaught the underlever would be in the way, as the combro needs a plain round barrel to fit on to.

You just mount it upside down on top of the barrel, instead of underneath.

I would have thought the lighting would/could be an issue unless you turn the rifle upside down.

Combros use an in-built IR light source, no other light needed.

I prefer a ProChrono myself, spent an hour today measuring who could throw a paintbrush the fastest. Try doing that with a Combro !

I get the odd bad reading but generally its not a problem.

hi baconbuttie what do you hunt with your paintbrushes? are they under 12ft/lb they may need to be on fac if you have a strong arm

[baconbuttie]

Just flys ! And 25 fps was the most we could manage with the indoor lights on, so I expect it's under 12fpe Would be more outside but I'm not risking that !
