Have been trying out my 5" coil on my cz6a and have noticed that a lot of nickels come in as foil. All the other signals seem to be OK . I had the cz6 converted to an cz6a and then bought the coil. Dankoski seems to imply that this is not too uncommon. Has anyone had this happen to them?? SkiWiz?? How has your coil performed on the cz5?

My coil is impedance challenged!!
- Thread starter prodrigsr
- Start date
Makes the unit really light and easy to handle, works well in trashy areas and places where larger coils won't go and gives good depth as one can usually run with higher sens.
One must remember older or deep nickles will come in as foil but a jefferson nickle at moderate depth should come in as nickle at least they did when I used a 5 inch coil.
Perhaps your coil is faulty or your mineralization is at fault ought ot cover it...One more thing they are more likely to give a large target alert on a large coin.

Mainly changed the connector to the box as many original CZ6 connectors failed..Your unit was made in 1992-1993....ever think it might need a tuneup due to its age..
I know some fellows had their CZ6 units tuned up and greatly improved their operation..Gosh I wish I could go in for a tuneup myself..

My cz will hit nickles solid most of the time but have had the foil to nickle bounce from time to time .I think it may have something to do with the ground conditions..
I've been testing a second hand CZ-70 Pro I just bought that came with both the 5" and 10.5" coils (it hasn't hit the dirt yet) and Nasa Tom suggested to do a nickel test on it, specifically on the 5" as they can become impedance "challenged".
To validate TID accuracy, the first test I did was on a variety of 50 nickels that included a mix of V's, Buffalo's, and Jefferson's (new variety included) some that had been dug and some not. The 10.5" AND the 5" coils ID'd 100% of the nickels correctly.
Granted these are only air tests, I'm sure in ground detecting may produce different results as you mix in the variables of ground mineralization, trash, iron, etc.

Ditto to what Dan just said.
Big target alert seems to be more prominant with the 5".
And don't let the size of the 5" fool you into thinking it won't go deep. I've found some really deep coins with mine.
Mineralization, moisture content and depth all play as factors as to what that older coin may actually read on the ID meter.
I've found many deep old nickels reading more on the higher side of the scale than the lower foil side. I've actually dug "V" nickels that read as high coin. They were deep and the length of time they were in the ground plus the type soil they were in must have had a "halo" effect leaching into the soil around them that caused them to read much higher than usual.
Usually...if it is actually foil under the coil...it will be at shallower depths and you can find it rather quickly.

Most of my Buffalo's and V nickles come in the nickle range with high tone with the occasional Foil to Nickle bounce.
So never discriminate past foil. I usually set disc on 1 which disc out Iron and click knob when I want to check out iffy coin signals.
If it's a nail you will usually get iron tone on one of the sweeps, I don't dig these.
When the CZ locks on to a coin it's a sweet thing.
