DISC 2
This control is identical to Disc 1 and allows you to further identify the target signal
being received.
With Disc 1 set at 5 to reject small iron and silver foil, commence searching.
Remember the detector is a motion detector, which means that the search head needs
to be constantly sweeping (except in pinpoint mode - see page 9).
You now need to set Disc 2 to ignore ring pulls.
Sweep the head above a ring pull and rotate Disc 2, at the same time depressing the
Disc 2 push select button with the thumb of the hand holding the metal detector.
When the ring pull signal disappears this control is set. Release the push button.
Your detector automatically operates in Disc 1 so commence searching (see
"Sweeping Technique" on page 13).
When you receive a signal, this indicates that the target could be a silver hammered
coin, 5p, ring pull, £1, 2p or gold etc.
Depress Disc 2 button and hold it. Sweep the target object again. If you are still
receiving a signal, then it is likely to be any of the metals found above ring pulls, e.g.
£1, 2p or gold etc.
Disc 2 gives you greater analytical skills than a single discrimination metal detector
but, even when Disc 2 does not give a signal, still dig up the target to avoid losing
silver hammered or 5p etc.
Three points to remember:
1.
Large iron objects, particularly if near the surface, can produce a signal
regardless of discrimination settings.
2.
Although Disc 1 and 2 are set to ignore metals at the same position there may
be slight variations in your detector and between different detectors.
3.
Practice, in air, with various metal objects so you understand the detector
capabilities and responses.
