combro cb-625 mk 4 chronograph ??

Hi jimmy D. The Combro is made by a guy called Robin Hewitt who lives on the south coast of England. He provides a superb return by post service for his little gizmo if you manage to shoot it, or it malfunctions.

It IS a real chronograph. One point is that if you're using it with an FAC PCP gun without a shroud or moderator, you'll probably need to make the first sensor stand an inch off the muzzle and avoid using it in moist air (which causes condensing water vapor to fool the first sensor).

I use it on all my airguns including an FAC airwolf.

I love mine. And the customer service is fantastic!

Robin is excellent! He repaired mine for free and sent it back to me from UK to US for free. I use it with the USB/Com port adapter on my laptop to display the velocity and record the strings.
