Hello, 1. Problem: Combro 625 is made from transparent dark or blue plastic. Because during the day the sun light outside is much more stronger then diode light inside (also in the shadows) - measuring doesn't work (work only inside), to correct this problem you need to cover upper part with black tape. 2. Problem: Mechanically after 1 shot with 16J gun brake holder between the barrel and front part with computer and display via back kick of the gun (tested with Hatsan 55S) ... (read more)

Works great with my PCP Air rifle inc silencer. Dead simple to set up and use, consistent results. Clips on with elastic band. Good value for money. (read more)

Combro CB-625 Chronograph can't fault it..
Brought mine found out it was a Grey import from uttings I think the warranty not valid in the uk..
UK models should have fps and pds buttons not metric M/S and J.
I also got a serial cable and log the data to the computer through the software supplied that really makes the unit for me saves having to press the reset button after every shot. I get a big display of the numbers on the pc and a shot count. You can then feed the Pellet.log file it... (read more)

Cheap & cheerful chrono. Does what it says on the tin. Using the pc interface (available from Combro) nice & easy. Have used it with both PCP and Springers with equally good results.

Small, light, Compact, great for "on the go" Testing to keep you aware of your rifles power. When i saw the Combro CB-625 Chrono (mk4)on the web it looked pretty small to me. when i purchased one it was even smaller couldn't believe it.
I would recommend for PCP's/ Co2 Rifles. havent tried it on a springer/ gas ram/ pistol so i will not say i wouldnt recommend it.
Use of the chrono is straight forward you press and hold reset button to set the pellet weight or settings. then reset press... (read more)

Had this chronograph for a year now and tested several guns with it.
It seems to be accurate but I have had some strange readings but put this down to temperature etc. (.22 pellet fluctuating between 610 and 780 fps)
Very easy to use--once you have entered the pellet weight the chronograph will tell you the ft per second and at the press of a button the Ft Lbs. It also remembers your previous results.
Be careful to make sure your pellet travels between the sensors and not at an angle. One... (read more)

I'm wondering how much light is needed to run this thing accurately?
In dim lighting conditions mine is out by 1/2 a ft/lb?? (read more)

I bought one of these little chronographs for £39.99, and I think it was a good investment, It has a basic LED screen and you attach it on the end of your barrel when you need to use it, it is adjustable for all barrel sizes and also it will adjust to size if you have a silencer fitted
For an airgunner to keep an eye on the power level of his gun especially to keep within legal limits, or for an airgunner who likes to make modifcations to their guns it is a must have
It gives the pellet... (read more)

The CB-625 is a compact chronograph designed to be mounted on the muzzle of an air weapon. Its produced by a UK small company and is not always available, though Ramsbottom's came up trumps for me. It has a very simple design, a plastic oblong case about 6cm*4cm*1. 5cm. The pellet passes along the top of the oblong passing through two plastic hoops which contain sensors. The unit has three buttons, one to show Feet-per-second, one to show Foot-pounds and one to re-set for the next shot.... (read more)
