Introducing the latest version of Combro cb-625 MK4 chronograph
The new version MK4 features a hinged support that allows the user quickly swing the unit away for actual test firing at the target without the worry of damaging the unit. The measuring path is also enclosed so measurments under broad daylight are improved.
The cb-625 MK4 is a compact chronoscope specifically designed for .177 and .22 airguns.

Use it as a tuning aid, consistency test, to get the most out of a cylinder of air / gas, to detect problems before they become serious ( e.g. leaking seals...etc. ), and to ensure the airgun is within legal specifications.
