Question

[prodrigsr]

Went hunting with my cz6a today and got four nickels. Two nickels came in on solid pulltab (no bouncing), one came in at solid foil, and another came in at square pulltab-nickel id. Who can explain this to me and do I need to send my unit in for another calibration??

My guesses ... were any of them fairly deep? Deeper ones can read a little low like at pull tab or maybe foil. On edge or corroded can change how the detector reads it. Were you working a trashy area? Nearby trash can affect the reading. What year nickles? War nickles (from mid 1942 to 1945) had a different alloy. Those should read slightly higher on conductivity than other Jefferson nickles.

I think that explains the bouncing one (pulltab-nickel), It was a trashy area but I distinctly remember the solid pulltab Id.

i have a cz-5 and sometimes nickels register on the dollar sign just like a penny,dime,or quarter. try re ground balancing and see if that helps.just a thought.

I have a CZ-5, and sometimes nickels ring in lower than nickel. I think that this is the improvement that they made when they came out with the CZ-3D. It supposedly Id's nickels better than the CZ-5's and 6's.
I hope to upgrade soon to either the CZ-3d or the F-75. I'm not sure which yet.

Not all coins are mixed the same, I have seen 2 Barbers dime read as Zinc's, in and out of the ground, on a CZ 6a,CZ 5 and a Whites Classic ID....
Not all Tabs read the same...
