Still having trouble... When using my Coin master pro it giving me good tone and the meter is saying its 50 cents or higher and lots of time 6-8 inches down, well i dig and i find iron nails. i have my detector set so that it should not pick up nails. i have changed the sensitivity up and down and sill getting them. Any ideas here?

Coinmaster Pro has Smart Notch levels. What are you running yours at?

Iron sucks. Fools a lot of machines. If your banging a loud signal and it's hitting half dollar, dollar, raise your coil up several inches and see if you still get the signal. If you are...probably iron. Even on my Vision, if I pass over a rail spike it rings like a half but with exp...I know to pass it up.

On some detectors, the 50c & $1 are for signals too deep for the detector to ID correctly. I had Coinmaster & Prizm IV, they are really detectors for areas of low
ground mineralization. Best wishes, George (MN)

Iron does have a tendency to fool detectors. A large piece of iron will return such a strong signal to make the detector think it has found something really conductive. Rusty nails can also do the same thing especially a nice round nail head or a nail that is bent to nearly 90 degrees or more. Rusty iron will form a nice conductive "halo" around it sometimes fooling a detector. So will balls of foil or aluminum. Iron harness rings will almost always signal around the dime area. It's because of the shape. It generates a nice return signal. Shape and size of an object does affect the return signal. So does the depth.

The nice about nails is they can tell the age of a site. If the nails are the cut "square" type then they are pre 1900.

my large number reading usually turns out to be an aluminum can real deep .
