Which Chronograph ?

[Airsporter1st]

I did the same test recently , a combro through my f1 beta and the combro was lower, i trust my f1 because it matches the skan at the club,

Thats the second combro i've come across that reads low, only 30-40 fps but if someone sets there gun at 11.5 it could actually be more!

Trouble is not everyone can afford a high end chrono and the combros are very popular, better to have one rather than nothing i agree, but unless you compare readings how will you know for sure?

Anyway back to the F1, works better in the shade even with the diffusers on, i was looking at some 12v led's so i can set it up in the shed, work in progress when i get round to it

I haven't found the thread, but I seem to recall that the Combro can be self calibrated. Perhaps someone will confirm this.

Found the thread

Yep forgot you can do this but again what do you compare it too?

Here is the way i got my Alpha Chrony to work inside, the light kit is expensive and if you are still close to strip lights it sometimes would show up errors,

So i went to B & Q and gota couple of LED spotlights and fixed them as shown in the picture, I have had no problems since and it only cost £10

Looks good. Minimal work and cost.

Already have some of those lights, which I use for target illumination during the winter, so I'll give it a go. Thanks.

Wow!.


I have not seen that footage on Youtube before.


Thanks Jonone


So if the combro was reading wrong and your rifle was confiscated by the police and tested


Possibly looking at a prison sentence.


Be Very Careful

Think we will just highlight the problem here.
Buy a new chrono and you cannot take it for granted it will read correct in 'your surroundings'

As we all know light changes, so does the readings!
The only way round it is with Infra Red or use in a controlled environment.

If the combro was wrong and if your gun was over and if you were pulled whilst going about your lawful pursuit and if your gun was tested......

This is just scaremongering.

How many responsible airgunners do you actually know that have been handed down a prison sentence solely for being over the limit?

Non, but not every responsible airgunner necessarily is a member of a forum and knows about chronos. IMHO all retailers, when selling an airgun to a newbie, should advise them to get one. The cb-625 is probably the most important and best VFM airgun accessory available.

I just watched that video again, according to the cb-625 his spread is 869 to 872. According to the Alpha it is 967 to 979.

Looks like a nice gun and as shot to shot consistency is the first thing to go out the window when cb-625 has a problem I think it is probably reading true

Wonder if the Chrony if folded right out ?

If not it would give a higher reading as it would be measuring over a shorter distance. Or have I got that wrong.

Spot on Ray, it would be higher.

My F1 always reads high (consistently 30fps) if I don't fit the shades.
Put them on and it compares very closely to the others I tried it against.
