V3I very faint tones at times?//

[Gregginohio]

noticed that sometimes i can hear very faint tones when sweeping,,maybe a very deep target...or a problem with the detector ,,using the spectra wireless headphones...eclipse 950 coil..coin mode..and somtimes in pro mode..think ive dug more trash in scrap metal than clad..using polar plot alot cause i forget the tones for different coins..found 22 widgets in a yard 1 inch square copper plates with a copper hook attached to the center,,all showed copper penny,,guy said it was early 1900,s electrical connectors,,cleaned out the yard of them..did find one penny,,gregg in hardin county ohio

it's modulation probably on a low setting, higher setting its going to be better distinguishing deeper targets.

Yes see if modulation is checked. If it is deep signals will be fainter.

I have dug hundreds of these which the old timers say are roofing tacks. Always show up as a coin from penny to quarter depending upon depth and soil. All are made of copper.

Yep, asbestos-cement and slate shingle anchors, most of us have found them around older houses. They are usually shallow and hit harder than a penny, I can usually tell when I'm over one.

Yep I have found a butt load of those rascals from one yard, they sound righteous and sure get your hopes up!

I just add them to the copper scrap bucket. Worth a little more than a penny a piece at Number 2 copper prices. I would rather dig these than pull tabs.

yep mine are square...and were all around the house ....thanks for the id..figured they were slate tile roofing holders..gregg

I've noticed occasional faint tones that I attributed to low/ no signal to the WHPs.
