cz-3d and cz-70 pro

Are these 2 machine comparable and would the notch function make the cz-70 pro more useful in the trash?

I don't have the need or use for notch function...they could eliminate it from detectors as far as I'm concerned.
I'm strictly a hunter of old coins and run my detectors without the burden of anything to slow them down or diminish depth. Many like and use notch and is a beneficial function for them. I don't like using any disc either...full out, tell me what you see and I will use my senses to pick and choose.

Depending on their tuning they should be comparable. Of course the notching would work better in trashy parks and such but again notch out one of the facets and one could lose a nice gold ring or gold coin or perhaps even a nice old coin. Indeed every facet on a detector has its plus and minus features..
