(I know ‘em, cause I’ve made ‘em…)

1/ Never using the cross sweep to determine how consistent a signal is. This results in a lot of elongated / micro targets that sound good in one direction getting dug up.

2/ Never using pinpoint to determine how solid, what size and shape a target is.  Pinpoint can also tell you if a signal is iron by the wide or narrow tone.

Pinpoint can also tell you when the machine is responding to part of a larger object—like wire. Without the “fail safe” of pinpoint, the machine’s high gain causes you to dig too many “flyspecks” that have zero chance of being of value.

3/ Not using the depth meter to get an idea of target size and location in the strata. The depth meter can help to correlate the other information you are getting to give a better idea of where and what size a target is.

4/ Sensitivity too high (targets don’t stand out), or small surface targets dominate the signal. Target tones become clipped sounding, machine loses depth.

5/ Bias too low (targets don’t stand out), dig unwanted alloys, (ie tin, bottlecaps), rust. While there’s such a thing as “reaching down” into the  iron to bring up signals, making the distinction between rust and non-ferrous metals is what the  Minelab Equinox does well.

6/ Recovery speed too fast, targets don’t stand out.

7/ Using a large coil with too much sensitivity—targets don’t stand out from the larger detection field.

8/ Using a large coil with the recovery speed too fast—machine does not have time to process the information from the larger detection field.
