TIP : If the signal detected with the subthreshold setting is large and
you can increase the sensitivity level, you can take the signal over
the threshold level and make it audible by increasing the sensitivity
for an instant. This way you can check the signal and see what kind
of a target it is.
Audio Boost
Boosts the sound of weak signals received from small or deep targets
making it easier for you to detect those uncertain targets. It is active
in the All Metal and Expert modes. It is recommended that audio boost
should be used on a temporary or as-needed basis because it will not
only boost the target signal audio but it will also boost the volume of
ground noise and false signals along with the threshold hum.
Audio Boost consists of 5 levels. As factory defaults, the Audio Boost
level is set to 3 in the All Metal mode and 5 in the Expert mode. To
increase the Audio Boost level, use the plus (+) and minus (-) buttons.
Discrimination
Discrimination is the ability of the device to ignore all metals below a
certain Target ID. In the discrimination process, the filtered ID range
is shown on the color ID scale at the top of the screen with black
color. For example, if you set the Discrimination to 30, 0-30 on the ID
scale will be shown in black and the device will not produce an audio
response for any metals with IDs between 0-30.
Discrimination cannot be used in Basic and Ground Anomaly & Cavity
modes. The factory default for discrimination is 0 for Expert and All
Metal and 10 for others.
When discrimination is selected, the colored adjustment bar with a
cursor showing the discrimination level, is displayed on screen. You
can adjust the discrimination level using the plus (+) and minus (-)
buttons. The adjusted level will be indicated by black color on the bar
and it will also be shown numerically inside the cursor.
In order to change the discrimination value, press the SETTING button
and choose Discrimination. Decrease or increase the value using the
plus (+) or minus (-) buttons. Please remember that certain targets,
other than the ones you want to ignore, may also be missed or their
signals may become weaker when using the discrimination setting.
In the case of receiving multiple IDs for the same target - let's say 35
and 55 - due to the orientation of the target or the composition of the
metal itself, if you set the discrimination to 40, because 35 will fall in the
filtered range, the signal strength as well as the depth may diminish.
NOTE : Discrimination setting works inversely proportional to depth up
to level 49 in Fast and Deep modes. In other words, as the discrimination
is increased, stability will increase but depth will be reduced and vice
versa. Above 49 though, both depth and noise will increase.
Stabilizer
This setting is present in the Expert mode and All Metal mode but it
has different functions in these modes :
Stabilizer setting in Expert mode :
This feature has 2 sub-settings: AutoReset and Stabilizer. These 2
settings are shown on the right and left in the same window. Stabilizer
consists of 5 levels shown in beige, AutoReset consists of 3 colors
shown in gray. The adjusted level of both settings are shown in orange.
If no orange bar is present, it means that both settings are off.
AutoReset and Stabilizer cannot be used simultaneously. In other words,
when one is active, the other one will be off and cannot be used.
AutoReset is active in the detection screen with the IPTU sensor only.
Stabilizer, on the other hand, can be used in both detection screens.
These settings are used to eliminate the drifts caused by ground and
temperature changes. Drifts may happen in the positive or negative
direction. During negative drifts, the Drift-Metal bar at the bottom of
the screen will up to the left, in the drift direction. Because positive
drifts have the same effect as metal, these will make the bar fill up to
the right, in the metal direction.
To eliminate these drifts, first pull the trigger once towards you and
release it to manually retune the device. If the drifts are substantial
and retuning does not improve the situation, please follow the steps
below :
If you are detecting with the IPTU sensor, increase the AutoReset
setting gradually until the drifts are eliminated. At level 3, the device
may miss weak signals. Therefore, if you suspect the presence of
metal in a spot, decrease the AutoReset level to scan over the spot
again.
If the drifts continue, you can increase the Stabilizer setting to 5 to
eliminate the drifts. As the Stabilizer is increased, the device may detect
weaker signals but will not be able to detect the targets anymore if you
hold the coil stationary or sweep back and forth over the target.
If you are detecting without the IPTU sensor, you can eliminate the
drifts by increasing the Stabilizer setting only as the AutoReset is
