Notch Discrimination on the X-TERRA
Ever wonder what you're missing?
Part two: Wednesday, October 06, 2010
To get a better idea of what you might be passing over as trash, let’s
check out the conductive properties of various items some might “skip
over” while detecting. Again, these numbers are based on the X-TERRA
70 and 705 TID, using the parameters of factory preset Pattern 2.
Remember, as I mentioned above, TID numbers are not cast in stone.
If you are passing over targets represented by the X-TERRA 70 and the
705 with a numeric TID of +2, +4 and +6, you risk missing rose gold
rings, platinum rings, white gold rings and some foreign coins.
If you are passing over targets represented with a TID of +6, +8 and +10,
you risk missing more white gold rings, more platinum rings, thin yellow
gold rings, lead and brass shells and the U.S. nickel three-cent piece.
If you set your detector to reject TID numbers +14 and +16, you will
risk missing very thin silver coins, the $1.00 U.S. Gold coin, thin yellow
gold rings, Shield nickels, Liberty V nickels, 40% silver War nickels, many
wedding bands, 10kt class rings, tokens and more foreign coins.
If you set your notches to reject +16, +18 and +20, you will risk missing
gold rings, tokens, various gold jewelry, 14kt rings, brass, the U.S. $2.50
gold piece, Indian Head cents, Flying Eagle cents, more foreign coins
and even large 10kt class rings.
If you rejected notch segments +20, +22, +24 and +26, you risk missing
more Indian Head pennies, the U.S. silver three-cent piece, the U.S.
$5 Gold piece, large gold rings, small silver pieces, gold jewelry and
medallions, and still more old tokens.
So there you have it. A few of the items that some of you might be
passing over, in an attempt to not dig foil, pull tabs and other “trash”
items. I realize that each of us has our own preferences for setting
the discrimination on our detectors. I suppose you could say we are
all creatures of habit. But the next time you hit that old park or picnic
ground, you might want to ask yourself if you’re rejecting notch
segments that include targets that you wouldn’t mind digging.
Enjoy the Hunt!
