Natural Limestone (Fla)

[FloridaDigger]

I have a Fisher F4 and have found a very strong signal (90-100) above a large limestone slab. Could this be natural occurring with limestone? My Pinpointer also shows a broad area (square meter) of strong signal on top of the limestone formation. I'm new at this and before I dig any more, I want to know if Limestone can give off this kind of reading. Thanks...

could be rebar or something under the slab?? or is it just a large formation of limestone? Or is the slab your refering to a old home slab?

Thanks for responding. At first, I thought it was an old septic tank cover until I got a better look at it. I uncovered a two foot section and its clearly a natural limestone formation.

It's probably just some pirate treasure.

Seriously, check the bottom of your coil to see if there is a silver dime stuck to it.

Naw, just a gold coin. Must be something else causing the high readings.

Did you ever find out what is was? I'm in central Fl also if you need a hand flipping or digging under or what ever you need to do.

I'd say that reading would be unusual for limestone; I'd be tempted to check it further.

my question is will a detector read thru 1 - 2 foot of limestone ? i know it will read rebar in concrete .
if it can read thru limestone then i wouldl say flip it or bust it . of course after you check for any hole that may hold a nail or drill bit or even a bullet ?

If it was me I'd have to check it... If you scan further on limestone and get no reading, but do in one spot, it's got to be something, right?

That answers your question.

Do you know what "tabby" concrete is? It is a very old 100+ years way of making concrete. It has large rocks in it. Could what your looking at be "tabby"? It could have rebar in it. Don't stop until you figure this out one way or another. Get a big electric hammer drill and see what is inside it. Some of the drills will also accept a chisel blade for busting concrete/limestone. I have one.

Thanks, I'm considering breaking it up and taking a look-see.

I would, even if its just so youll know, if the same thing happens in the future.
