Chronograph

[Shooter259]

a combro is around 30 quid. last i hear if you went onto their website they would send you one posted for £40.40

they do the job and can easily fit into your gun bag too. well worth the money. if you're thinking of doing a massive string of shots, they can be a bit awkward as you have to reset it before each shot, but work well enough.

I've been on the combro website and they want £49 now??

Hi all,

No doubt. These are the best chronographs available for the money.

I have 4 chronos, including the Combro.

Advice, however, is that the muzzle should be at least 10" from the chrono, to prevent spurious readings.

CO2, or heavy dieseling can greatly affect the readings.

This is an obvious disadvantage with such system.

My favourite chrono is the Skan, well worth investing in.

I noticed, during recent checks though, that my Combro runs about 4 fps lower than my others.

A best mid range chrono, and probably the most versatile, is the Chrony F1, though they can be a little light fussy.

Kind regards,



Phil

Have got the correct settings entered in your combro?
The box or instructions useually have a calibration number on which when entered here http://www.chronoscopes.com/ on the help me calibrate it page, will give you a number between 000 -200. 000 being -1% , 100 zero and 200 +1%
100 is the standard set calibration but mine from the calibration number is set at 109 which should read true. Remember, if your Combro is set at 200 = +1%, then a reading of 777 fps is actually 770 fps give or take a fraction..

1.....is it best to do Task2 first...then test for groupings
2.....do i need the interface cable - or just write down all the speeds .....
3.....does the lead come with the PC software
