Trashy
areas
Trashy areas. When you go out for the first time to one of your
favorite parks or school yards do not be surprised if you seem to
not be able to get a thresh hold. This is due to 2 different things.
First of all the stock coil being 10.5 inches covers a lot of ground.
if you have a target under your coil that is discriminated out in
your machine and you have a good target close to it you might not
be able to pick it up. This is better known as masking. I have tried
this, by placing a nickel on the ground where there is a piece of
buried iron trash near by and have not been able to pick up the
nickel no matter what direction I hit it from. The second reason
sort of goes hand in hand with the first and that is not only does
the detector "see" a lot more "horizontally"
on the ground cause of the larger coil, it also "sees"
a lot deeper, or "vertically" picking up that REALLY deep
trash. Between these two things, is the cause of having virtually
no thresh hold in trashy areas. Even some of those areas that you
have done before and thought where relatively clean of trash you
might start getting a hard time. I have come up with 2 different
ways to deal with this problem. The first is to turn the sensitivity
WAY down. I'm talking 10 or below until you get a semi constant
thresh hold while you are moving the coil. Sometimes this works,
sometimes it doesn't. The other way to deal with this problem is
to set your audio mode to "AUDIO 1" and see if that helps
out some. There is no sure fire way to fix this problem till Minelab
or someone else comes up with a smaller coil. We will just have
to do the best with what we have for now.
