cz3d question

I have been getting frustrated with getting 'HIGH COIN" hits then digging up rusty nails and other similar junk EVEN THOUGH I AM RUNNING MY DISCRIMINATION IN THE PULL TAB AND EVEN IN THE ZINC CENTS NOTCH.I always run sens at 4 or 4.5.mostly in enhanced mode since I work old sites.Is this normal or is there a problem with my machine?Any help would be appreciated THANKS IN ADVANCE!!!!
 
dem,
You will get lots of high coin sounds while using the 3D. What you want to do is dig only the "repeatable" hi coin sounds. First, I recommend running 0 disc. Listen to all of the iron grunts. They will help you distinguish iron targets from good targets. When you get a hi-coin sound, pinpoint it to center it. Now sweep from all 4 directions. If you only get a beep in one direction, leave it in the ground. If you get a beep in 2 directions, your odds have gone up. If it repeats in all 4 directions, hit your knees and dig. Now is this a perfect solution? NO, but this is my experience and I dig very few nails with my 3D. Iffy targets can produce but the good/bad ratio won't be high. It's up to you and how much digging you're willing to do. Also, when you pipoint, how big is the target? This will clue you in to whether or not this is a coin sized object. Practice pinpointing with a coin to find out how to profile a target. If your target is larger than coin sized, your odds of digging a coin are reduced. But remmember, often times coins are dropped in groups and can give you a larger pinpoint profile.

Good Luck,
Dave
 
Dem,

Dave gave you very good advice. Definitely set your disc to zero so you can hear those iron signals, as well as the rest. It will help you learn what the machine is telling you. If the sites you are hunting are still active, and have a lot of aluminum trash, you might want to hunt in the salt mode. Depth loss is very minimal only on very small (earring backs, etc.) gold targets, but the coin sized targets will still sound off just fine. Often I will check signals in both modes for more information.

which is older sites without a lot of aluminum trash. To answer your queestion, try to descriminate out a zinc penny while in the enhanced mode by cranking your descrimination all the way up to 6, I'll bet you it will still hit on the penny. Now flip it to sale mode, it should descriminate out the zinc.

Now, if you get yourself a hand full of nickels and either bury them or pass them in front of the coil, check to see how many of then will register with a hi tone and how many with a mid tone, mine either registered a nickel with a mid tone or a mid to hi tone bounce and registered round pulltab on the meter.

So, when in the field, if I came across a round pulltab signal whether it be mid or hi tone, I would flip to salt mode and if the meter stayed at pulltab, it was mostlikely a pulltab, but if the meter switched to nickel, it mostlikely was a nickel.

Now, the end of this story is, in order to find good targets, you must dig a lot of junk, but if you only dig hi tones like the manual says, you mostlikely are leaving nickels behind.
 
You are right about the coins in groups,,,Here in Japan I fine more than one many time and just today also...two in the hole and they both had different readings outside the hole.
Found these in the old picture together two were stuck together and 3 were just in the area.
Later Dave
