Discrimination
1) Press the DISC button to set the DISCRIMINATION mode. In this mode
the LCD screen displays “DISC” and the Max level (the first level) of the
DISC/NOTCH display lights up.
2) Press the DISC/NOTCH button, then press the (+) or (-) buttons to adjust
the discrimination range. The DISC/NOTCH display will change
accordingly. The patterns on the LCD screen also change depending on
the different discrimination ranges. For example: The left four pillars of the
DISC/NOTCH display light up to indicate that a quarter or a penny can be
detected. However screw caps, pull tabs and iron nails will not be
detected.
3) In this mode the detector produces a low audible tone when it detects
objects such as screw caps, nails and nickels.
Notch
1) Press the NOTCH button to set the unit to the NOTCH mode.
2) In this mode, “NOTCH” appears on the LCD screen and the Min. and Max.
Levels (the initial levels) of the DISC/NOTCH pillars light.
3) To adjust the NOTCH range, press the DISC/NOTCH button. Then press
the (+) or (-) icons. The DISC/NOTCH display pillars will light up, starting
at both the right and left sides. The pattern left unlit in the middle shows
the metal being “notched,” or chosen for detection.
4) In this mode the detector produces a low audible tone when it detects
objects such as screw caps, nails and nickels.
NOTES
1) A battery icon display indicates that the batteries are weak and should be
replaced.
2) When hunting for different coin types it’s a good idea to set the SENS to
4.5 inches. This is because the alloys used in pull tabs and some coins
can affect the accuracy of the unit.
3) The sweeping speed and the height of the search coil above the ground
will also affect accuracy. We suggest a slow sweeping action and a height
of about 1 – 2 inches (2 – 4 cm) above the ground.
4) While sweeping the search coil back and forth try to keep it level with the
ground for the entire width of the sweep. If you tilt the search coil you will
not obtain an accurate reading.
