CZ 21 - Going from the Wet to the Dry

[berryman]

Any one out there try using the CZ 21 in both the surf and on the dry sand? I'm interested to learn where you get your best performance and how you have to tweak the settings when going from one medium to the other.

Well, I've got a CZ20 but the CZ21 should behave like the CZ20. Very little if any adjustment is needed going from the water to wet sand to dry sand. You may have to reset the ground balance slightly, but most beaches I've been on, it isn't much of a change. I used to run with the volume between 4 and 5 but now I run about max and don't worry about trying to figure out how deep the target is in the sand. Sensitivity as high as it will go without falsing, that's normally 4 to 5 on mine. Discriminator set on 0 to listen to all tones.

And are you getting good target recovery with your CZ 20 in both locations?

Yes! At least in my opinion I am.

Same experience here with my CZ20 converted to CZ21. Very easy detector to learn, although with anything else, the more you use it, the more you pick up little tips on what to dig. Rarely if ever have to do much with ground balance moving from salt water to dry sand. CZ20/CZ21 hits really hard on silver and coins, good on gold (except thinner gold chains which most non-PI detectors have trouble with) - probably not as deep on gold as the Excalibur/Sovereign GT, but that depends on experience I think.

I'll say one thing too - since you're in the sand, don't skip past those really faint/deep signals, even if they sound like iron or especially if they bounce between the 3 tones. MANY times, after you take out the first scoop of sand and re-check the hole, the signal will lock on, and quite often it's NOT iron. At least often enough to be worth digging them since it's sand and easy to do.

I'm thinking of getting another CZ-20/21 for my wife so she can join me in the wet sand and shallow water.

Truer words were never spoken. Can't tell you how many times on a clean beach with few targets, where I'd get a low tone, dig out a scoop, pass the coil over the target again and now she'd return a mid or high tone. You'll recover a lot of goodies that would otherwise have been passed up this way. When a good target's just out of range, it'll drop down into the low tone/iron range.

I also have a CZ 20 and recently bought an Excalibur2 and I'm wondering if the iron tone on deep targets applies to the Excal also?

My take on this. With all machines...accuracy diminishes with depth. With excall2 nulling out iron sure there is a given chance you will either misss a target because it thinks its iron and really isn't...or because its buried beneath an iron target. The excal 2 usually picks up the targets under irion objects.

I was not a fan of the cz 20 for a few reasons. One of them was the tone id system. You ended up hunting in pinpoint mode more then anything. Things are built like a tank though.
