A guide for U.S. coin-shooters
A metal detector does exactly what the name implies. It detects metals. Set
to accept everything, you will nd nails, foil, pull tabs, jewelry, coins, tokens,
relics etc. Anything that is metal. In order to avoid digging those targets
you don’t want to dig, we implement a feature known as discrimination.
Metal detector discrimination is basically the same for all makes and models.
Some may do it better than others, but the theory is universal. Simply put,
discrimination is the ability to adjust your detector so that it accepts most of
the targets you want to dig and rejects most of those targets you don’t want
to dig.
Some detector models use a variable discrimination (such as Minelab’s
Sovereign GT). When you set a variable discriminator (potentiometer) to
reject a certain item, every item with a lower conductivity value will also be
rejected. For example, if you set your detector to reject a certain pull tab
with variable discrimination, you will also be rejecting U.S. nickels.

Notch Discrimination on the X-TERRA
Ever wonder what you're missing?
Part one: Friday, September 24, 2010
Discrimination on the X-TERRA is comprised of notch segments. Notch
discrimination allows the user to accept or reject specic ranges of targets,
based on their conductivity. You can reject individual notch segments,
groups of notches or randomly select those segments you want to reject.
With notch discrimination, you can chose to reject the notch representing
pull tabs, and set the notch representing nickels to be accepted. For many,
notch discrimination allows you to cherry pick a site more thoroughly than
variable discrimination. But don’t think for a minute that you are not missing
“goodies” with either type of discrimination.
