10%. That is, if the device detects a coin at 30 cm depth in the “Econo-
my” mode, then in the “Norm” current mode there is a chance to detect
it from 33 cm. According to the place and search conditions, choose
whether increasing the depth of extra phantom signals (if they appear
with increase of current) and a possible deterioration in the identifica-
tion of shallow deep targets. However, when searching for very small
gold jewelry on a freshwater beach, especially thin gold chains using
small high-frequency sensors, use the “Norm” mode. A decrease in cur-
rent reduces sensitivity to similar specific objects.
MODE S ALGORITHM
From our experience we know that the majority of metal detectors react
to flat iron objects as nonferrous. To assist in solving this problem the
specially developed S algorithm is used to assist in properly identifying
these targets.
The most effective use of this algorithm is in identifying small flat iron
objects (15 cm2), such as beer caps, rusted pieces roof tin, etc., with a
signal rating greater than 10.
If the device detects an object with a “questionable” non-ferrous signal
(high tone) and it has a rating over 10 then using the S-Algorithm can
help to identify these type targets.
There is no need to use this algorithm for a definitive low-pitched signal,
i.e. when the subject is clearly iron. Remember though, to monitor the
signal rating level of the target.
It should be pointed out that this mode does not apply to general search-
ing, but only to help clarify the type of metal of a non-ferrous response
and to decide on the need to dig.
The S Algorithm has virtually no effect on the hodograph display of
non-ferrous targets.
It should also be noted that when increasing the surface area of iron
objects the effectiveness of the S-algorithm decreases.
Important! When using the S-algorithm, the sensor wiring over the target
should be wide, covering the entire sensitivity zone to this target. Only in
this case will the correct operation of the algorithm be ensured. In this re-
gard, the use of the S- algorithm in littered areas is problematic.
