CZ6A penny ID in salt mode

I`m new to the forum and have found a lot of useful info here. I use the CZ6A with excellent results. Recently in the "normal" mode, the 6A sees no difference
between the clad penny and copper penny. This is quite annoying. In the "Salt" mode the 6A sees the difference between the pennies. I ground balance around 5 with sensitivity at 5 or 6. Question, Am I losing depth or sensitivity using the salt mode on non salt conditions? Does this machine need a tune up? Am I missing something? any ideas will be appreciated...Thanks

Hmmmmm. Almost sounds like this unit has been converted to CZ-3D status. . . . hard to tell. If you hunt in the 'Salt' mode......you will lose VERY little depth on coins. If you hunt for gold jewelry.......and you are in the 'Salt' mode; you will lose a lot of Sensitivity/depth on gold........especially smaller gold items. Do you know what your air-test range on a dime with your unit is?

Tom, It is not air testing well. With ground bal @ 6 and sensitivity @ 10 in all metal, dime @ 7 inches, quarter @ 8 inches, Penny @ 7 1/2
nickel @ 7 inches. No difference between salt and normal. In iron Disc. mode, Dime @ 8inches, quarter @ 9 inches, nickel @ 71/2 inches and penny @ 8 inches. These numbers seem low to me. I have found coins @ 8 inches but no deeper. The batteries are new. Is this info useful?...Thanks

Yes, , , , something is wrong/incorrect with your detector. CZ-6a should acquire a clad dime well beyond 11" with 8" coil.

Tom; can this be corrected? I think this is an analog machine. Are there adjustments that can be done?

In most cases; yes. Right now.......it's hard to tell if it is component error/breakdown.......contamination.............or simply just needs a tune-up.

Do you want to look at it or shall I ship it to fisher?

With the low depth abilities.......I would recommend sending it to Fisher. If not for that........I'd take a look at it.
