That's an interesting little unit. Since you have to put the muzzle so close to the box your actual numbers may be a bit different than what you see here. Most guys here place their chronys 2-4 feet away from the muzzle. Whats important is the relationship from one shot to the next, and that's what this chrony will give you. It looks like it is made for airsoft guns, be sure it will detect velocities like those from your marauder before you get it.

Ray,
Youve mentioned that the numbers may differ in my UFC chronograph, which one will give me higher velocity? The chrono which they used here where they placed their chronys 2-3 feet away or my chrony which i put in the muzzle? I shot some string today with jsb 18.13gr today with settings of
Valve meter 3.5ccw
Hammer spring 6cw
Hammer strike 8cw
This settings give me max velocity Around 830 fps with 2600 psi fill, i was hoping i would be getting a higher fps
