See chart below for description of tones induced by different metals in different modes:
Ferrous, gold and silver targets will generally register within their
corresponding category icon ranges. Targets that are not gold or silver register
within the same range according to their electrical conductivity.
Note the electrical conductivity of a target depends on both its composition and
size. Silver is more conductive than gold so it registers farther to the right; and
the larger the silver object, the farther it registers to the right. There are a wide
variety of metals and no target can be identified for certain until unearthed. See
coin reference table below.
Jewelry, Coin and Artifact modes have predefined audio tones for the various
Target Category groupings. The All Metal mode has a single proportional tone
(V.C.O.) for all categories. The Custom mode is programmable and users can
assign any tone to any of the Target Category groups. The Custom modes
default tone for all categories is a single proportional tone (V.C.O.). V.C.O.
varies in pitch and volume depending on the depth and size of the target. The
custom tones are automatically saved when the unit is turned off.
