Question on CZ-3D

[mike56]

Hi, I have been reading this forum for about a year and this is my first post. I purchased a CZ-3D in January of 07, have had some moderate luck mercury dimes, silver quarters, Indian head and wheat's etc. but no nickels. Yesterday that changed. I went to an old picnic grove from 1860 - 1910, this area has been in beans and corn from one year to the next. Running my detector in enhanced mode and taping a piece of paper over the meter to listen only to the tones and not watch the icons. Anyhow I got a midtone in enhanced and switched to salt mode and got a high tone removed paper and checked again midtone round tab in enhanced, and high tone nickle in salt. Decided to dig because I wasn't getting many signals, out popped a shield nickle with rays. Went a little further same thing another shield nickle without rays, same reading. Also found a faty 1864 Indian Head which registered midtone square tab in both modes.
My question is? I thought the CZ-3D was supposed to bring older nickels into hightone in enhanced mode. I checked them out of the ground and same thing. Also ran my discrimination at zero but when I turned it up to experiment in enhanced mode it discriminates out nickel at round pull tab but does not discriminate out nickels in salt mode until 4. I s this normal? This was done while they were in the ground and out. Also found a 1868 2 cent, 1901,1888, and 1896 Indian heads, and all of these came in hightone and coins. Wonder if I would be better off to switch back and forth from enhanced to salt when I get the round tab reading.


Thanks,
Mike Simpson

P.S. Also wondering the best way to clean the nickels?

Older nickels and nickels near iron are some of the toughest targets for a detector to classify. I have seen them read up close to zinc on many different machines. Also the 3D's nickel window on the high end is not much different than a regular CZ's to keep digging tabs to a minimum. Why the salt mode locked on is a mystery, perhaps its the soil conditions or your machine is not quite in tune.

hi mike!
i don't own a cz-3d,however was considering purchasing one..to be honest,i am glad i did not buy one!..after much reading on this forum,i drew the conclusion that their effectiveness is limited to church grounds,private homes,and where you hunted,in old picnic groves..to my way of thinking,unless you are hunting these places
ALL the time,and running in "ENHANCED" mode,then you would be equally well served with the wonderful cz-5,and keep it in salt mode,or regular mode..in other words,i just cannot justify purchasing the cz-3d,because EVERYWHERE you hunt these days old.or new has "tons" of aluminum trash that the 3d "sees" as "high tone"..you are very limited to where you can hunt with it effectively,and leave it in enhanced mode!..i guess if you don't mind diggin' trash all the time.then you should rush out ,and buy one before first texas stops making them!

regards!
