How does the Omega improve over the F5?

[marcomo]

For those of you who use or have used the Omega 8000 and the F5, what improvements do you see in the Omega over the F5?

I have a F5 and like it a lot.

I know the Omega is about a year newer design.

Expert detectorist Mike Hillis prefers the F5, I want to hear what others who prefer the Omega say.

Thanks!
