GOING DETECTING WITH THE AT PRO. QUESTION

[sheiswe]

so I'm sure this is somewhere on this site. But, do I dig those faint sounds that tend to disappear and nothing even shows up on my screen? I heard they're just really deep targets. Can someone break this down for me?

Those signals are targets just out of detecting range (depth) where your machine see's something but the TID can't categorize the target. Dig them, some will be a surprise...

To get some of the harder stuff where I am I ground balance, max sens, and slowly grid or pick a smaller spot to work thoroughly. When deep enough some of the small old copper coins will give a faint or soft high tone and maybe only bounce up and down to say 60ish on the display. When I get that combo I become VERY focused and often do a small rotation or circle around the target to really hear it. I have no idea about the no see ums as I tend not to dig them, it's just too deep and I have gone down to pipes too many times. Alternatively however, as a fellow has already said, deep is often equated with old. It could be old junk, a Chinese cash coin from the 1700's, or a chunk of copper pipe. It's your decision to make whether to dig or not. What often determines whether I want to go the extra mile or not is the sites history. If it has proven to give old relics or coins, or is simply an old occupation site, then those are additional factors that I use to decide to dig or not. Turn of the century school yard with a deep soft high tone, I will dig deeper. 1980's urban grass strips by sidewalks, no, that's shallow clad, knick knacks and jewelry, if in an area with no prior development or historic use.

Yes, dig them all. Last time I dug one of those it was a 17th century knee buckle, 100% complete. Down 11" or more.

Mainly the area I dig is woods, found stuff from s early as around the 1700s

Great answers and all true. Another little blurb that causes this phenomenon is a deep, rusted chunk of iron that will break basically into red powder. Sometimes it is so far gone that you will find little to no trace of artifact, but was concentrated in one spot and was enough to set your machine off. Hope this helps, Ddf.

I dig everything because I'm desperate for something cool.

some times it is the halo effect on an artifact. The ground around the target is ionized much like the metal itself and thus make the deep target look bigger and more shallow. But when you start digging, you can disturb the ionized dirt and then the target is now its normal size and thus maybe 2-3 inches deeper than you have dug so appears to disappear.
