Double D Setting
Monoloop (Mono) Setting (with Double D coil)
Strongest Signal
To pinpoint a detected target sweep the general area with the
coil taking note of where the strongest signal is received.
By shortening the length of the sweep it should be possible
to draw an imaginary line in the ground where the strongest
signal is located.
Line up the target at 90° from the initial direction and repeat
the process. The object is located where the two imaginary
lines cross.
Note:
With the Coil/Rx switch set to Monoloop or Cancel, when
using a Double D coil, pinpointing will not locate a target in the
centre of the coil; the target will be slightly to the left. The left
edge of the coil can be used to pinpoint shallow targets.

Tip:
If detecting on loose
dirt or gravel you can
actually draw the lines
using your shoe or pick.
