THE BASICS OF METAL DETECTING
This metal detector is intended for locating buried metal objects. When
searching for metals, underground or on the surface, you have the following
challenges and objectives:
1. Ignoring signals caused by ground minerals.
2. Ignoring signals caused by metal objects that you do not want
to find, like nails.
3. Identifying a buried metal object before you dig it up.
4. Estimating the size and depth of objects, to facilitate digging them up.
5. Eliminating the effects of electromagnetic interference from other
electronic devices.
Your metal detector is designed with these things in mind.
All soils contain minerals. Signals from ground minerals can interfere with
1. Ground Minerals
the signals from metal objects you want to find. All soils differ, and can differ
greatly, in the type and amount of ground minerals present. This detector
has proprietary circuitry to automatically eliminate interfering signals from
minerals that occur naturally in the ground.
NOTE: This detector will not completely eliminate interference from all types
of minerals. For example, the detector IS NOT designed for use on wet
sand saltwater beaches. Another example of soil this detector will not
eliminate is any soil containing large concentrations of iron oxides, which are
usually red in color.
If searching for coins, you want to ignore items like aluminum foil and nails.
2. Trash
You can see the Target-ID value of the buried objects, listen to the sounds
and then decide what you want to dig up. Or you can eliminate unwanted
metals from detection by using the DISCRIMINATION feature.
Metal objects are identified along the 9-segment Conductivity Arc. This scale is an
3. Identifying Buried Objects
indicator of the relative electrical conductivity of different objects. Segments to the
right indicate more conductive targets. Iron objects, which are usually of lesser
value, illuminate on the left-most segments. Silver objects illuminate on the right-
most segments.
The 3-segment graphic indicates the relative depth of a buried metal object.
4. Size and Depth of Buried Objects
This graphic can indicate the relative size of different objects or their distance from
the searchcoil. For a given object, the more distance between it and the searchcoil,
the more arrows illuminated.
