Do nickles give a high tone on the CZ 21

[JASONSPAZ1]

Also what kind of coin depth are you getting with the 8 inch coil while detecting inland. I can only own one high end machine at a time. I would use the cz 21 often at parks woods and fields. However i want to do even more water hunting and i do not feel to comfy going deep in the water with my sovereign Gt. I need opinions as to how a cz 21 will perform equally inland as well as lakes and oceans. I am intrigued that nickles may ring in as a high tone on the cz 21.

thank you

From the manual:
"Note the different audio responses over the various
targets. Your CZ-21 will respond with a low tone over
most iron or steel targets. Pull tabs and foil will give a
medium-tone response. U.S. coins give a high tone
response."

So, yes, US nickles are high tone. I've used my CZ20 inland. It's heavy but can certainly be used inland with very good results. The CZ 20 and 21 is locked in salt mode. Over dirt it looses a little sensitivity to very small, low conductors when compare to a CZ in normal (not salt) mode; but it is not much of a difference compared to normal mode. It will pick up stud earrings, but maybe not just the broken off stem piece of a stud earring with no clasp on it.

CZ's are one of the deeper detecting VLF detectors under most most conditions. Best detection depth is normally gotten with a relaxed sweep speed; you do not want to rush it. 8 inch coil is the one to go with. There are trashy areas inland where you really want a 5 inch coil, but working slowly with the 8 inch you can handle most conditions.

CZ21 is just a land CZ without a meter in a waterproof box and cons are its locked in salt mode, heavy and bulky without a meter for land use...but excell in either salt or freshwater applications...

My CZ21 generally gives a mid tone for nickles - not always, but most of the time.

Ditto. Nickels are the only coins that seem to give me a mid tone also. Pennies, dimes and quarters are high tones.

Doesn't matter I dig all medium tones anyway, and for sure all high tones. I also dig all bell tones. Never know whats in the water here.

I just got my CZ 20 and don't know about real world applications but air testing on mine shows a nickel hitting mostly high tones, but there were some mid-tones mixed in. Obviously that can change in soil or sand depending on mineralization and ground matrix. I would definitely go with what the experienced folk here have posted. Either way it gave a solid beep, but my machine knock's out or at least diminishes/breaks up a nickel with the disc. set at 4. I have the 8" coil btw.

I'm with scubadetector...dig all mid, highs and any low tones mixed with mids or highs. one of my nicer finds was a Pt 950/18K Cartier combo ring that registered as a high - I thought it was US coin or silver ring and was pleasantly surprised. when in doubt, dig it out!!!
