Pulse Induction And charcoal
Does anybody still have problems with charcoal setting their detector off?

Re: Pulse Induction And charcoal
What do you mean still, it always did and still does, even on the Mighty GPZ7000, you will get a signal on charcoal, but hey dig right through the charcoal because sometimes, just sometimes there is a nice nugget under the charcoal
Like this 13 grammer from a few years ago using the GPX4500

Re: Pulse Induction And charcoal
Nice one Dave,always best to keep checking your holes b4 filling.
As to your question Adrian ,charcoal gets me every time ,all I can do is dig it out and check ,no easy solution.

Re: Pulse Induction And charcoal
Yep & because of such finds, every in ground target response has to be thoroughly checked.
Carbon is an interesting one Adrian. Charcoal or Graphite, being an allotrope of carbon (a form or structure of which it can exist in, different to that of diamond) poses both properties of metals & non metals, making them both electrically conductive, as well as conductive to metal detectors. Yet graphite, in its atomic structured form is soft, whereas diamond is extremely hard. Not that your question refers to nor asks for any of this, but I thought I'd throw it in anyways.

Re: Pulse Induction And charcoal
Just a topic that I thought might be of interest to some of the more recent starters on the forum to gold metal detecting.
Speaking from my own exp with charcoal, the only detectors of my own that have been effected by charcoal have been VLFs.
The Infinium and the TDI seem to be unaffected. A small piece that I detected the other day with the Gold Bug Pro gave a medium strong signal in all metal and an Iron tone in the middle of the gold disc range. I had the iron break point set at 40. At that disc setting a sluggy 1.6g nugg also gave an iron tone. Normally I would set the iron point at approx 20 but at that level the charcoal gave a positive signal in disc mode and I had to set it to 40 before the tone changed to an iron tone. There was no way that I could separate the gold from this bit of charcoal.
The TDI & Inf did not respond to the charcoal but gave a nice hi tone on the gold.
The weight of each these items is very similar.

G'day Adrian,my 4500 is a sucker for charcoal too
But my SDC never has a problem with it,or any problems with ground noise,hot rocks etc. In fact,if the SDC gives off a signal that there's a target under the coil,it will always be a METALLIC target..every time!!
Not always gold,unfortunately..but always metal

Re: Pulse Induction And charcoal
Maybe has something to do with the pulse rate, or maybe the GPXs are not pure PI, or maybe there has been nuggets inside all of those noisy bits of charcoal. or maybe they are not charcoal, or um um err I dunno.
