CONTROL PANEL
CONTROL KNOBS ARE AS FOLLOWS:
1. SENSITIVITY:
a. Click right to turn on. Click left to turn off.
b. Turning the knob clockwise increases the detector's sensitivity; the
higher the sensitivity, the deeper targets will be detected, and the more
likely the detector will be to detect very small targets.
c. As you turn the knob, notice that the SETTING value at the bottom-right
of the screen will display your current sensitivity setting.
d. The sensitivity has two ranges. From 0 to 70, the sensitivity increases
on a linear scale. Above 71, the sensitivity threshold level starts
changing. At values greater than 70, some internal circuit noise will be
noticed. The higher the number, the higher this background "static" will
be. Many seasoned detectorists prefer to operate at high sensitivity
level, with the accompanying noise. They call this "working into the
noise" When some background level of noise is audible, small changes
in the volume and tone will denote the presence of buried metal.
2. DISC / AT AUTOTUNE
a. Click counterclockwise to the AT icon to enter the AutoTune mode.
b. This is the detector's most sensitive mode of operation.
c. It is a motion mode of operation; the coil must be in motion to detect metal.
d. Autotune mode induces a hum whose pitch and volume vary with the
size of the target. Larger targets and targets moving closer to the
searchcoil will increase the tone's pitch and its volume.
DISCRIMINATION
a. After clicking on, the knob's rotation controls the detector's discrimination
setting. Left in the far counterclockwise position, without clicking the knob
off, turns the discrimination function off; all metal targets will be detected.
b. Rotating the knob clockwise increases the level of discrimination.
c. Notice that as you rotate the knob, the SETTING values at the bottom-
right of the screen will change. At the same time, target icons across
the top of the screen will disappear to indicate that entire target
categories have been eliminated
