Notch Discrimination on the X-TERRA
Ever wonder what you're missing?
Part two: Wednesday, October 06, 2010
Now that I’ve outlined how the ferrous vs. conductive properties are
represented by the visual and audio TID, let’s evaluate some targets. If
you turn your X-TERRA 70 or 705 to the Coin/Treasure Mode, and set it to
hunt in factory preset Pattern 2, you will be rejecting notch segments -8,
-6, -4, -2, +2, +4, +6, +14, +16, +18, +20, +22, +24, +26 and +48. You will be
accepting notch segments 8, 10, 12, 28, 30, 32, 34, 36, 38, 40, 42, 44 and
46. Those of you who have performed TID tests with your X-TERRA know
that this setting will accept U.S. pennies, nickels, dimes, quarters, half
dollars and dollar coins. A Coin hunters dream? Not necessarily. Although
repeated tests indicate that modern U.S. coins will TID within the
ranges set by Pattern 2, there are many variables that can aect the TID
information provided to the user. Some of these variables include coins on
edge, adjacent trash that distorts the information sent to the processor,
multiple coins in close proximity, target depth, soil conditions, ground
balance settings etc. There are simply too many variables to guarantee
that one TID number will always represent a specic target for every site.
Coins wear thin; jewelry can be of many dierent metallic compositions,
shapes and sizes. And, the mineralization of the site can uctuate
dramatically. Hopefully, what I am about to share with you will help you
nd more treasures. You will likely have to dig more trash while nding it.
But if you understand what your discrimination setting is doing for you (or
to you), you’re bound to nd more good stu!
