Here's a good question you guys give me your opinions!!

[88junior]

Why does it seem that CZ'S and most Fisher detectors seem to do better in mineralized soil compared to others which require dd or widescan coils to get through bad ground? My CZ-5 ground balances around 5 on the faceplate and they are just the easiest detectors in the world to ground balance. My soil consist of red clay and slate rock which have tons of mineralization but I've found coins and relics over 11" deep stuff that I had missed with other detectors even with dd coils. So my question is why do these detectors cut through ground minerals with out the use of a dd coil and get targets so deep?

If I had bought my CZ5 first I would have saved a fortune!
Just sayin...

From the manual:

Two VLF ground compensation signals are
transmitted (one at 5KHz, one at 15 KHz), giving the circuitry
two ground compensated target response signals to
analyze, compare and identify.



The Minelab units that use FBS and muli-frequencies also are great in bad soil.

I have spent so much money looking for a unit better then the CZ and have not found it yet. When Dave Johnson designed the CZ he out did himself and everyone else.

Hi, yeh as "tmanly" quoted the CZ machines have dual frequency 5kHz and 15kHz.
