For speed on the sand, the F series...since its competition, the CZ's dont like a lot of other detectors around..and the F has that HZ function.
The lightweight of the F will allow you to really cut an enormous swath fast! The heavy control of the CZ even if its hip or chest mounted would get in the way if its a matter of speed. Full disclosure: I have never done a competition, so I dont know how deep they plant targets, or if they just toss them out there. But I do speed sweep beaches with great success with the F and an aluminum 5" sandscoop. Practice with each to see which one you are more comfortable with, settings and all...it will be a matter of tones, and speedy recovery methods, I would think, so the faster you are at that, the more ground you can cover. It sounds like fun, maybe I will give it a try sometime. Good Luck!
