ALL METAL- Used to search for all kinds of metal objects. Used in
general searching. In this mode, the unit will respond with a “di-di” tone to
all metal. This mode cannot discriminate metal type.
DISCRIMINATION (DISC) - This mode can help you to search and
discriminate the target type, based on different tones (short, long or
silence) for different metal targets. Set the DISC mode switch to “0”.
Slowly rotate the control clockwise to high position to reject more objects
you don’t want.
When DISC/TONE is set to 0, unit will respond to any metal object with a
long tone. As the controller is rotated clockwise, the unit will sound a short
tone, or even be silent to ferrous metal objects. This means the ferrous
metal is rejected. Rotate the control further clockwise. Nickel, zinc, and
copper will be rejected. When the control is set to 10, most metal objects
are rejected, except silver. The unit will respond with “du” tone to silver.
TONE - Based on DISC/TONE control, the unit can discriminate the metal
type with high or low tone. A rejected object sounds a low tone, which is
different from DISC mode. When DISC/TONE is set to 0, it sounds a high
tone to any metal. As it is rotated to high position (clockwise), it sounds a
low tone to ferrous metal such as nickel, zinc, or copper, and sounds a
high tone to silver. To get better tone identification, we recommend you try
testing your unit a few times.
TARGET- Used in ALL METAL mode to pinpoint the target accurately at a
lower sensitivity. When detect metal object, you can press TARGET to
pinpoint the object. Hold the searchcoil 50cm or more away from the
ground. Press and hold down the TARGET button. Sweep the searchcoil
over the search area and release the button when you hear a “di” sound.
After about 1-2 seconds, hold down the red button again, the “di” sound
disappears. Sweep the searchcoil closer to the ground and you’ll hear the
sound again. Repeat the above steps until you locate the object.
