Signal
Each time a target is detected, bars will illuminate showing the strength of the target’s
signal.
If all 7 bars illuminate, the target signal is strong.
This may be a large metal object.
Or it may be a coin-sized metal object close to the surface.
If only a few bars illuminate, the target signal is weak.
This may be a deeply buried object, even a big one.
Or it may be a very, very small metal object, close to the surface.
The depth of a coin-sized object can be confirmed using Pinpoint.
In DISC Mode, pr or – will change two detection parameters:
1) Tone identification
2) Target elimination
As the level of discrimination changes, the target segments along the arc on the screen
will be displayed in one of three states:
1) Blank (no segments displayed)
2) Grey (segments displayed in a shaded colour)
3) Black (segments are solid black)
The segments along the arc will remain illuminated in this state as you are pror-.
This displays your chosen target discrimination parameters.
At any time during operation, you can view the discrimination settings in one of two
ways:
1) On the bottom-right of the screen the DISC value is always illuminated.
•
This value is the division between the LOW tones and V.C.O. tones.
•
This value is the lowest target value which be detected with V.C.O. tone.
2) Whenever you press + or -, the arc will illuminate and show your current detection
parameters.
The first press of + or – will change the discriminate level by one value.
