The Discrimination(DISC) and Sensitivity(SENS) have “stay-put” segmented position
adjustments. Segmented controls allow the operator to make adjustment without
removing the headphones to view the position numbers.
1. VOLUME CONTROL(VOL)
“VOL” regulates the loudness of target response. The volume control adjustment
is continuous and not segmented.
“VOL” has a power switch (ON-OFF).Through the “VOL” control, you can
easily power on or power off your detector.
2. DISCRIMINATION CONTROL(DISC)
“DISC” can help you to discriminate the target type. Rotate the ”DISC”
counterclockwise, the beginning position is ALL METAL. In this mode, the unit will
respond with a “di-di” tone to all kinds of metal. Slowly rotate the “DISC” control
clockwise, the ferrous metal objects will be rejected first. The unit will sound a short
tone, or will be silent to ferrous metal objects. This means the ferrous metal is rejected.
Rotate the “DISC” control further clockwise, the unit will reject more objects you
don’t want. The rejected metals in order of conductivity are: iron, zinc, copper and
aluminum. When the “DISC” is set to max, most metal objects are rejected, except
silver, the unit will respond with “di” to silver.
Most of the metal targets are alloy. A lot of factors will influence the detection
results, such as the different environments, size of the targets. You should detect
patiently and correctly and practice more times to determine the type of targets. The
rejected metals in order are iron, nickel coin(5￠ ), pull tab, zinc coin(1￠ 87
version),copper(1￠ 76 version) and aluminum coin. Notes: silver coin(25￠,50￠
and 1＄) will not be rejected.
It’s better to test your metal detector on a table before you use it the first time.
Place the detector on a wooden or plastic table, and adjust the search-coil so the flat
part points upwards. Please take off your watch, ring or other metal objects on your
hand or arm. Sweep a sample of the material you want the detector to find about 3
inches above the flat face of the search-coil. Slowly rotate “DISC” knob clockwise,
you can pinpoint the rejection point.
In general use, you can set the DISC to ALL METAL position. When you detect a
target, rotate the “DISC” till you could determine the type of the target.
3. SENSITIVITY CONTROL(SENS)
“SENS” is used for setting the sensitivity of the detector. In general use, you can
set the “SENS” to a higher and have no interference. Slowly rotate the “SENS”
clockwise. When you hear some sound signals, rotate it counterclockwise a little. This
will be the discrimination reference position.
OPERATION
1. Wear your headphones. If you are operating the detector with your left hand, you
should wear the control ear-cup on the right side, thus giving your right hand the
freedom to make adjustments.
