DISCRIMINATION
9
The disc control is enabled when you switch the all metal/disc. to the disc.
position .The fully counterclockwise position is marked in red - nugget. In this
position you won’t have any audio discrimination of metallic objects. You
should know, that in heavily mineralized ground tiny pieces of gold can
sometimes look like iron to the metal detector, and
small iron pieces can look like gold. So we
recommend this mode of operation for nugget
hunting.
The next zone is the AMD (all metal disc) zone. The
professional TH-ers use this mode of operation to
study the new sites they are working on.
The advantage of the
AMD adjustment is that you
won’t miss any metal target in the ground. The bad
thing is that you’ll have to loose time for digging too
many unwanted ferrous targets like pieces of wire,
nails, etc.
The next zone of this control is
relic . As we earlier mentioned in this position
the detector will eliminate only the tiny pieces of wire. All the bigger sized
targets will be accepted. Most professionals prefer working with this
adjustment of the
disc. control, because the detector is really deep with such
a low discrimination level.
The next zone is coins. Here you’ll have good rejection of the ferrous
targets, and you’ll accept all the non-ferrous targets. We recommend this
position of the
disc. control for searching areas littered with iron trash. If you
have too many pieces of foils rotate the disc. control after the foil zone. Have
in mind that the categorical foil rejection will bring to the rejection of some thin
golden jewelry.
If you decide to use even higher level of discrimination, for example the last
zone or the one before it you’ll reject the foil, more of the pull tabs, screw caps,
but you’ll loose some coins like the nickel 5 cents. The detector will keep its
good response to more of the coins, like 1 cent, dime, quarter. Even the lower
conductivity ancient coins like the Greek obols, diobols, the Roman asses,
follises, sestertii, the Byzantine follises will produce nice, smooth response. A
big part of the jewelry will be rejected, as well as the thin small gold coins. We
do not recommend such high levels of discrimination.
Even if you are with the highest discrimination level the big oxidized irons
will not be discriminated. Though they produce a clear response, the more
experienced detectorists manage to discern them and avoid their digging.
