Zeagle Envoy Vs Zeagle Onyx

[theiszy]

I was wondering what was tje difference between the onyx and the envoy 1st stages? What makes the onyx a "high performance" reg vs the envoy.
I understand one is a cold water reg and has a different finish, but what is internally different that makes the envoy perform better?

They explain it all in the Zeagle regulator owners manual available on their website. It contains info and explains the differences on the envoy, onyx and F8.

thanks Helimech,
looking at the manual is describes the special features as: "rapid air adjust knob" and "cold water thermal sink" and the onyx is also environmentally sealed. the first 2 features are both for the second stage, so does this mean that the Onyx is really just a cold water Envoy? the main differences being the 2nd stage that come with it?
does anyone else know more about these or has pulled them apart personally?
