I have not used a cz70. I've used CZ5, CZ20 and CZ6a. On the beach I like to hunt auto tune (all metal) with a barely audible threshold and flip to discriminate mode to add target information. In discrimination mode, the CZ platform will slide an ID down as the target gets deeper. A deep gold ring can ID as iron. You are looking for short smooth target audio reactions in auto tune. If you run discriminate mode, don't run the sensitivity too high or you will be digging false signals.
Hopefully someone who has used a CZ70 will chime in ... if I recall it has notch setting capability, for the beach, I'd make sure nothing is notched out.
On most beaches, I'd opt for the big coil unless it makes it too nose heavy for you to use, the 8 inch is a great coil that does not give away much depth to the 10 inch, but does not cover as much ground either. The only place I see using the 5 inch at a beach is if it is very rocky with big rocks that you need to get between.

Here is an oldie but goodie hint page for CZ's, although it is mainly focused on detecting dirt rather than beach.

I have experience with the Cz 70 , but not on a beach. just land use. You could set it up like a Cz20/21 if a user would give their setting’s. The cz 20/21 is pretty much the same as any other CZ , only with no ID meter . HH Tony

I will be using it in land as well mainly on pasture looking for deep coins.

On land, you can , if you want just put the settings on the preset (red circle numbers) and go hunting. You need to read the manual on the ground balance procedure. The push button method is fine. The volume adjustment gives you the ability to have modulated audio. Below 5 gives you modulated audio, and above 5 is boosted volume (all loud). I like modulated because soft high tones tend to be good Deep targets. The sensitivity can be run higher in the digital czs , but 3-4 is fine and you won’t blow out signals . The higher than 4 numbers tend to make the targets seem larger than they are. In my test garden with sensitivity set at 4 , it still hits 8” targets. If you have any more questions , just ask and i will try to answer you.

On the beach I like to run the CZs well into the boost range to bring out the deep targets in autotune mode. Good targets still present as narrower than iron does although I still don't walk away from as many bottle caps as I might if I walked away from all the wider sounding targets.
