cz5 foil reading
- Thread starter Sonny(IN)
- Start date
As a nickel corrodes, it degrades the signal. Crusty corroded nickels will start "bouncing" Foil / Nickel, then as they corrode more, will come in solid Foil. I've seen really toasty Shield nickels bounce Iron / Foil.
The 3D changes the segments of the meter and lowers the segment for Nickels.

one of the main advantages of the 3D as Allen said.
I have found many old nickels with my 3D that shoed up as foil in "salt" mode. Sooo.. dig your foil signals to find old nickels with your CZ5.

On any unit older nickles, buffalo, shield, V because of their metalic composition just come in lower than a traditional Jefferson and may hit foil or have a foil nickle bounce. Over the years have seen this on various units not just a CZ5..Allen is correct as the CZ3D advanced mode nickel segment is just geared a little lower to catch these in nickle. Made especially for old areas and old coins..Must add deep Jefferson nickles will also read lower into the foil zone on most units also and don't know he reason for that...Certainly nothing wrong with your CZ5 just the way it is(period).....

the nickel reading in enhanced mode. You still get plenty of foil readings. The worst offender is the beavertail. They read nickel and can drive you nuts.

Not only will some Foil targets come in as Nickel in Enhanced, but some pulltabs will hit as coins as well, as really crusty/corroded IH's bounce Zinc/Pulltab.
WVADigger, don't get me started on the beavertails! I drive myself nuts with those things, thinking an indicated 4" deep Foil/Nickel bouncer might just be a Buff (I don't find many of those, and haven't found a V Nickel yet). Each time it ends up being a beavertail @ 1". GRRRR!!

But I don't think it's the metallic composition of the Nickel itself, but rather the corrosion present on the surface of the coin that affects a the Nickel's conductivity. Take a Buffalo Nickel or a V Nickel that have never been buried, and run an air test.
Most of the Buffalo nickels that I've recovered hit Nickel, with the ocassional Foil bounce. I've recovered a couple early Jefferson nickels, one a '39, the other a '41, and both were heavily corroded. Both gave Foil/Nickel bounces. The '39 was in an old road-side park that dates back to the '30's. Once I had it out of the ground, it gave only a Foil hit. The '41 Jefferson was under a pine tree at an old zoo. The turpentine and pine pitch had corroded the nickel so much that the COPPER in the nickel had leached out and turned green on the exterior of the coin.
Five years ago, I went with a couple other friends to a ghost town here in OK. One of my buddies was more of a sifter than a MD'er, as he would clear the brush from an area, dig 6" of dirt out, and sift/detect the dirt by hand. Then he'd dig another 6" of dirt out and repeat. He recovered three Shield Nickels that day. They were heavily corroded and had started to flake away. I did a quickie airtest on one, and it would only hit as Iron. Go figure.
Heck, I've noticed lately that Zinc Pennies that are really eaten up will bounce Square Tab/Zinc, and may only register as Square Tab. Maybe my meter is going on my CZ-5.

I have seen 2 Barber dimes read as Zink on a CZ 6a,CZ5, and on a Classic ID, in and out of the ground.The mix was wrong when they made them. 1 was a 1906.
I dug a 1898 "V" Nickel that read as as foil on a CZ 6a.
I saw 2 war Nickels give a nickel to tab bounce, one was nickel to SQ tab and the other was nickel to beaver tail tab bounce.
If your in a old area, you better dig everything above iron.
I hunt with a father and son that use the old 1260 &* 1265 and they have dug some real good coins, yes they also dig a lot of trash, but you never know for sure what a target is until you dig it.
I have dug good coins that were just a one way hit and so have my hunting buddies.
Good rings also read in the foil range.
You never know what people have lost, until you dig it.

Yup, they bounce all over the place.
You're right about digging everything above Iron in old places. Did you see over on the F-75 Classroom board that someone out in California found a $5 gold coin? Came in as a Tab on his meter.
Probably the best gold rings, thin women's rings with stones, come in as Foil. I've found several LARGE gold rings, many that come in as a Tab, and two real honkers that register Zinc Cent.
Oddball Silver objects, like earrings or something that does not form a closed loop (like a broken ring), small silver objects, like crucifixes, and large silver chains, will usually come in around Tab.
