Depth of Use
Many metal detectors can sense items up to a foot below the surface. There are
several factors, which can affect the depth your instrument can detect an
object. They are the type of metal the object is, the size of the object, and
the composition of the soil. Certain soils contain minerals such as iron that
can cause interference, or the object's halo. Some items that have been buried
for a great amount of time can affect the conductivity of the earth. Another
cause of interference is from other objects that are buried, and most frequent
cause of interference is the brand and quality of the metal detector. There are
a few specialty metal detectors, which can sense objects as far below the
surface as five feet. Then there are the highly advanced metal detectors that
have displays in which you can pinpoint the exact metal, and how far below the
surface, the item is located.
The fact that many metal detectors are very similar, there are a few significant
features, and functions to keep in mind when deciding on the metal detector
right for you. You should do is identify the terrain you most likely be using
your metal detector. Then you have to know just what you want to search for,
like coins, relics, treasure hunting or gold and silver.
Coin shooting:
This is simply searching for coins after ball games, concerts, or just general
looking for old coins.
Prospecting:
This is when you search for valuable metals, like gold nuggets.
Relic hunting:
This when you look for historical items, such as Civil War weapons, belt
buckles, coat buttons, and such.
Treasure hunting:
Treasure hunting sometimes calls for research, and mapping in order to locate
where a cache of gold, silver or anything of value rumored to have been hidden
may be found. |
