the 5000 and cole

a bloke in my home town who's a fulltime prospector, he has said that the 5000 is picking up the fire ash (coal) more than the 4s and the 45s. is this because they have trimmed down the timings like the fine gold and have them running a bit smoother so you hear these signals abit easyer? has anyone picked this up as well?
cheers

How ya goin Paul,

it's just my opinion but most of the detectors I have used will pick up an old fire. Which means ash & coal will give you a target. Once ya start diggin, if its an old fire, move on.
Then again, some old sod may have buried his stash under the coals

I very rerely hear charcoal on my 5, and thats only when i'm running very extreme settings and
the ground is wet, then i hear a slight warble from it, but i just have to suss out the slight warbles
could be a deep bludger.

Has the bloke noticed it more with a certain coil than others ?



Pete

Now this raises a good subject, I have dug up burnt out tree stumps, I need the experts to tell me, why do they give a good signal ?? Please explain ?

the bloke that said this has had every M/L detector and said the 5000 seems to pick it up more than 45s and the 4s, it could be the settings he is runnig
cheers

my old gp extreme picked up more charcoal than my 5000. could be his settings.

My Extreme, 3000 and 4000 all picked up charcoal and ash, especially burnt tree stumps. I just got used to it and moved on after a quick scrape.

I think its carbons ability to soak up water, and when that water is alkaline the salt stays in the carbon.
So wet or dry it has a much different decay then the surrounding soil.
That and carbon can be conductive. Combine that with salts conductivity.
This is just speculation on my part.

Buried charcoal was a real issue with my 3500, particularly
using a DD coil.
it was even more of a problem is the soil was wet.
My 5000 using mono coils does not seem to suffer the same
problem. NV chris is probably on to it with his explanation.
The 5000 will trundle over day old burnt ground with lots of fresh charcoal
without a whimper.

Got to agree with Chris.

Carbon is conductive and often you'll get a soft but somewhat broad signal thinking it's a largish nugget at depth, only to find it's an old tree stump burnt into the ground.
Many of these are lightening struck trees, possibly hundreds of years ago, and sometimes you're down 12" or so before you see the charcoal start to show.

My 4000 loves charcoal.....loves to find it!
Where as my mates 5000 doesnt even make a sound over it.

Madtuna,you will probably find those charcoal deposits are the roots from a tree a few meters away. When a stump is burned the roots will smoulder for months in the right conditions,burning all the way to the tips over a period of time.
