get a response. Keep in mind that for accurate target ID, the coil center must pass directly over the target.

5.Note the response you get over small targets. For small iron or steel targets, the meter needle will usually lock in the “IRON” category. Most pull tabs, foil, nickels and the newer zinc pennies will also be correctly classified. Silver coins, copper coins, and the newer clad coins will ID in the highest category.

6.Note that an enlongated ferrous object such as a nail will give you a double “beep” as you cross it from end to end and a single “beep” if you cross its center.

7.Most silver rings will ID at the highest end of the scale. If you have enough gold rings you will note that some fall in the round tab category, some in the “FOIL” category, some in the square tab category, a few in the nickel category, and very few in the remaining coin categories. This is due to the fact that the combination of size, shape and conductivity of a particular ring will almost always add up to a target that is electronically identical to either a piece of foil, pull tab or nickel. Most metal detectors have a difficult time separating gold rings, nickels, tabs, and foil, but, the patented circuitry of your CZ-3D can easily tell the difference between nickels and most trash. Better yet, it will allow you to find many types of gold rings while completely ignoring at least some types of pull tabs and small pieces of foil.

8.Note also the different audio responses:

a)an iron target will give you a low tone

b)foil a mid low tone

c)tabs a medium tone

d)coins a high tone.

9.When you go over a large, shallow target the CZ-3D will respond with a distinctive belltone. This is due to the fact that metal detectors can only identify small targets. What usually happens is that the detector circuits will overload and identify a large target as “good” (silver, coin, etc.). Your CZ-3D, however, will alert you to the fact that the target is big and shallow and can not be accurately identified. Big deep targets, however, will usually be classified as a coin. Also, be aware that large coins on
