DEAD SILENCE=TARGET?

[THE SCURVY DOG]

Hello All.

Question: If Im running with a just barely audible threshold and suddenly I go dead silent..........backaway and threshold returns .........swing again over area and silent again...........is this nulling/iron? Or is this( when using a GT or EXCAL) a super deep target? Beach hunting .........wet-sand.

Thank you

I have a explorer and excal.I'm not too experienced with excal, but on the beach any change in threshold, silent or otherwise is worth a scoop.My theory has been proven to produce really deep and otherwise missed targets.

A change in the threshold like that can be a deep good target, unless it is concentrated on an area to large for jewelry or coins then it is most likely deep iron. Some guys hunt in Pinpoint mode and when this happens they have to take out a scoop or 2 of sand and recheck the hole. If a solid signal is then produced they switch to discriminate mode and check for iron null or good signal.

Oldbeachnut has some good videos on You tube showing him doing this exact thing with just a slight change in the threshold.

or black sand

Hello All ,

Thanks for the input. Seems as though the consensus is to scoop the sand above null area and see if the loop starts sounding off once I push it into the open hole ............then determine if the signal is repeatable ...............thereby letting me know to keep on a-scoopin..............rapido!! Wavering or broken return signals ............leave it be.

It sounds like it's nulling iron to me....When in doubt dig it out. Then you know for certain

the GT or Excal will null on anything at your disc setpoint or below. they dont just null on iron. deep targets and the soil can make them null also, try different sens settings, could be set to high if this happens often. also cross check in all metal and see what you get. like Dig says, dig and you will know and I will add learn what the machine is doing.

What they said.

As Neil says, i will add that almost 99% of the time a null from all directions is positive iron, a shady null with a squeek is usually something deep and worth investigating or at least taking some sand off looking for the solid null, especially if its faint in all metal.

Next time it happens switch to AM or Pinpoint and dig it up.
Then you will know.
