at 3 feet, a large piece of a cast iron stove at 4 feet, and a larger piece of tin sheet
metal at 4 1/2 feet using the standard 8 inch Coinsearch coil. Sometimes all a person
has to do is go another inch deeper to find the target.
Case 2:
You have a signal that seems contradictory, having both good and bad
characteristics. Sometimes the target mimics a partially rejected trash target, or is
clipped, broken, or ragged sounding depending on how fast you swing your coil or
from which direction you come at the target. A questionable dig.
Solution to case 2:
It's usually a good target next to one or more bad targets. Most of the time just by
going very slow over the target will produce two signals. One good and one bad.
Sometimes it takes a ninety degree turn to produce the good & bad signal using a
slow coil sweep speed. You may have to dig the trash first because it is the strongest
pinpoint signal or you may try to pinpoint by staying in the discriminate mode and
sweep slowly one way then 90 degrees the other way.
Another possible solution is that it's trash but you won't know that until you dig it up.
Case 3:
You ID a penny or better in conductivity but when you dig you find a nickel instead.
Solution to case 3:
The nickel had been in the ground a long time creating a halo effect that makes the
nickel register in a higher conductivity range. Another possible solution is that the
nickel is laying on top of another target of higher conductivity. Don’t forget to
double check the hole after recovering the nickel.
Case 4:
You get what appears to be two good coin signals close together. When you sweep
the target 90 degrees you get one weaker coin signal. You pinpoint two coin signals
close to each other. You dig and find nothing in either hole.
