Combro - CB625 Chronograph mounted on a TM G36c (Stock, Gearbox not upgraded)

I purchased this unit direct from the mfg in the UK and up to now I've just been trusting the people I buy airsoft from on the gearbox upgrades. Well now I can test to see the fps!!!


Combro - CB625 Chronograph Computer Program

The unit itelf is all plastic, and I also bought the PC adapter and everything works great!!! Each shot get's registered on the Chrono unit itself and with the PC adapter it show's up directly on the PC with things like averages and conversions. All logged data is saved to a text file.

Chronograph results in FPS out of 5 shots:
