Glossary of Terms

90Understanding your X-TERRA - Final Words

Concentric coil

A Concentric coil has an inner circle and an outer circle wire winding. Its search

pattern is cone shaped and can be useful for accurately pinpointing a target.

Conductivity

Conductivity refers to how well a target allows electrical current to ow through it.

In other words a highly conductive target has low electrical resistance and therefore

allows current to ow more easily.

Discrimination

Discrimination is a metal detector function that recognizes the dierences between

various types of targets. The discrimination feature on Minelab metal detectors

measures two target properties: ferrous properties and conductive properties.

Double-D coil

A Double-D coil has two overlapping wire windings in the shape of two D’s (one

reversed). The characteristics of a Double-D coil are stability (especially in heavily

mineralized ground), good depth and sensitivity, and a very thorough search pattern.

Eddy currents

Eddy currents are tiny electrical currents that are induced into targets when a metal

detector’s electromagnetic eld is present. These eddy currents then generate an

electromagnetic eld around the target which can be received by a metal detector’s

search coil.

Ferrous

Ferrous objects/targets contain iron and therefore are attracted to a magnet. e.g.

horse shoes, nails, tin cans.

Frequency

The frequency of a detector refers to how fast it is sending (transmitting) signals into

the ground and receiving them back. Dierent frequencies nd certain targets better

than others, e.g. high frequencies nd very small targets while low frequencies nd

deeper/larger targets.
