How do metal detectors work?
In a simplified manner, all metal detectors work on the principle of electromagnetics and
the effect on conductive metals. A metal detector uses battery power to create a
penetrating magnetic field that enters the ground. Anything metallic will then become
charged with the magnetism, similar to a paper clip becoming magnetized after touching a
standard magnet. The magnetized metal below ground then sends a signal back to the
metal detector alerting the user (usually by sound) to the fact that there is something
metallic below ground, what kind of metal it found (high-end units), and how deep the
metal is (high-end units). NOTE: Most metal detectors can detect up to 12 inches below
the surface. Many will work much deeper..

The Basics of Metal Detectors
All metal detectiors, regardless of brand or model, have the same
components.
1) Stabilizer--this is usually an arm brace that keeps the unit steady
as it is swept back and forth over the ground.
2) Control Box---this is the "brains" of the metal detector and contain
the circuitry, controls, speaker, batteries, and microprocessor. It may
also contain a jack for headphones,
3) Shaft---this connects the control box to the search coil. It is often
adjustable so it can be set at a level for your height.
4) Search Coil---this is the part that actually senses the metal below
ground.

Components of Metal Detectors
To make an educated decision about buying a metal detector, there are several things you should
consider:
PRICE---metal detectors are relatively inexpensive, but you must decide how much you intend to
spend, not only for the detector, but also for accessories like headphones, digging tool, and carrying
bag, if desired.
USE---if you plan to use a metal detector many hours a week, then we suggest one with more
electronic features than if you plan to use it only occasionally. It is a fact that the more features you
want, the more you will need to spend.

LOCATION---do you live near the water or inland? Do you intend to search for coins and jewelry,
hunt for relics, search for gold or use the detector under water? The fact is, all detectors,
regardless of brand, have water proof search coils so they can be used in shallow water at the
beach. They cannot be used entirely under water, although there are units on the market for this
use. There are also different detectors on the market for searching for coins and jewelry, relics, or
gold. But the fact again is, that most common detectors purchased today are "general purpose"
coin, jewelry, and relic detectors.
Now that you know all about metal detectors, you should know that it's a fun hobby and detecting
can provide hours and hours of entertainment. Plus, you may even find valuable coins and more.
Maybe, it's time to get out there!!!
