1. SENSITIVITY
Use
and
to increase or decrease sensitivity while the
SENSITIVITY line is highlighted.
Maximum sensitivity setting is 10.
Minimum sensitivity setting is 4.
If the detector beeps erratically or beeps when there are no metal objects
being detected,
reduce the sensitivity.
The searchcoil produces a magnetic field and then detects changes in
that magnetic field caused by the presence of metal objects. This
magnetic field that the detector creates is also susceptible to the
electromagnetic energy produced by other electronic devices. Power
lines, microwave ovens, lighting fixtures, TVs, computers, motors, etc….
all produce EMI which can interfere with the detector and cause it to beep
when no metal is present, and sometimes to beep erratically.
HOW DEEP WILL IT GO?
The Platinum Metal Detector will detect a coin-sized object, like a quarter,
to a distance of about 9” from the searchcoil. Large metal objects can be
detected to a depth of several feet. Detectability is directly related to the
size of the metal object -- the larger the object, the deeper it can be
detected.
Accuracy of target identification is also related to distance from the coil.
Beyond a distance of 8”, the accuracy of target identification begins to
diminish.
Discrimination and All Metals modes have independent sensitivity
settings. First highlight the mode, then adjust the sensitivity level for that
mode.

2. DISC. LEVEL
Use
and
crease or decrease DISCRIMINATION level.
Each time you press
, a target category is eliminated from detection.
Elimination occurs from left to right. When a category description (for
example “IRON”) disappears from the display, then targets classified in
that category will not be detected.
Pressing
reverses the discrimination process. With each press of
, a category description will reappear, indicating that targets
classified in that category will again be detected.
Discrimination is a cumulative elimination system. Targets can be
eliminated from left to right on the scale, with each additional press of
, resulting in more objects being eliminated from detection.
3. NOTCH
Use
and
to notch target categories IN or OUT while the NOTCH
line is highlighted.
Whereas the discrimination feature eliminates all categories sequentially
from detection, the NOTCH control allows you to selectively include or
exclude target categories from detection.
With each press of
or
, the notched category moves across the
display screen. As you move the position of the notched category, you
are
changing the detection status of the selected category.
• If a target category was previously eliminated (word not visible)
then notching that category will return it to detection.
• If a target category was previously retained (word is visible) then
notching that category will remove it from detection.
Only one target category at a time can be selected for notching. To notch
multiple categories in or out, press
again while NOTCH is
highlighted. Each subsequent press of
allows you to set an additional
notch. Each time you press
, followed by
, the notch
program will begin by changing the status of the IRON segment.
