G2 and Hot Rocks question

[2 Much Trash]

I've been hunting a new area that has produced some nice finds. Problem is, this area is loaded with hot rocks, I mean loaded. With my current detector they give the same tone as silver, brass and lead no matter how I adjust the machine. From all indications this spot should produce some good stuff but these rocks are wearing me out. When I get the G2 how will it perform in this situation.
Thanks Guys, Willie

My understanding is you should be able to eliminate hot rocks a lot by groundbalancing to the hot rocks....
Gold should still signal off and cold rocks will make a strange kind sound...
I think...I'm in NYC so I cannot check this at this time...

How deep are the hot rocks? Are you sure that's its not just bad ground and if you could get a picture I might could help.

Ground balancing to eliminate these hot rocks sounds great, but I would be worried about eliminating the good stuff as well, since these things read just like silver, brass, etc. I guess a test garden may help, burying some of these rocks along with the stuff I'm looking for.

I'm digging these rocks anywhere from 3 to 8 inches. I've dug a few of them thru the years and never gave them much thought because they were few and far between. But this place has them everywhere. I'm sure its not bad or hot ground, my machine runs extremely smooth in this area. Just last week I dug a merc dime and 2 3 ringers in a small spot but also dug a half dozen rocks because they gave me the exact same tone in all metal or discrimination settings. All these rocks are about 1 to 1 1/2 inches, jagged irregular shaped, medium brown color, almost hard as granite, but extremely light weight Can't send a picture right now camera's on the blink. I'm hoping these things have some iron content and the G2 will give a low tone. I'f that be the case I'm Sure I'll be diggin' some goodies.
Thanks for your response, really appreciate the interest

Look at the speed dial is it jumping ?

Hot Rocks are not really a problem with the G2 and your 1266x will see those on a regular basis. I was thinking about the G2 and you already had one. Sorry, about that

 

[JimGilmore]

So why post on the gb/g2 forum ?

 

[2 Much Trash]

No apologies needed my friend. I'm sorry I wasn't clearer with my original question. When I said you know that machine, I meant you know that machine because you have one. So the G2 can deal with the hot rocks, thats what I needed to know. Thanks, Ken
Talk to you soon

Well I hope you get one soon and see the differences in the detectors as far as old tech and new tech !

"but extremely light weight". Very important clue.

When most folks talk about hot rocks, they're talking about iron-bearing rocks, and discriminators can knock them out. It sounds like you're dealing with something entirely different, most likely coke from smelting operations or from coal-burning stove ashes. The stuff is conductive like nonferrous metal, and large pieces can even hit up into the high coins range. If most of it's small you may be able to discriminate it out. If you've got a good "ear" you may learn the sound difference, coins have a crisper response whereas coke has a broader duller response.

Because I'm purchasing a new G2 and just trying to get as much information on its pros and cons from you folks with knowledge and experience. Thought in would help when I finally get it out in the field. I've posted several questions here recently and have had extremely helpful and open minded responses. My question today, while fresh in my mind, was in regards to the hot rocks issue and how the G2 would deal with them. It wasn't about another detector. Please read the last sentence of my original post.

Jim took me too, but welcome aboard

 

[2 Much Trash]

You may be right. I've found quite a few iron legs and doors I thought from wood stoves. But may be their from coal burning stoves. I sure hope so. That means possibly a large camp site
Thanks for the info

The G2 / Gold Bug Pro, they have got to be one of the best detectors on the market right now for the money.

As Dave J. said, the coins will sound crisper, as does rings and some other jewelry. You really need to listen to the sounds while the target is in the ground before you dig it up. Move the coil all around and over the target at different speeds to hear what it sounds like, once you have mastered this, you will be able to tell what the target is, like them darn crown bottle tops, they can really sound like a quarter when in the ground, but if you use the coil to size and pinpoint the target, you will get a feel to what the target might be etc.

Sometimes can slaw can throw things out of sync, when it reads as 57 - 59 and sound just like a nickel, I still have trouble with this, still trying to find the tell tail signal on chopped up cans. Foil can also cause problems too, like when you think your digging a dime it turns out to be a small bit of foil that was used to wrap a sandwich etc. Big foil has a dull sound to it, it's not as crisp or pronounced like a nickel or dime would be.

The G2 / Gold Bug's love round things, even when on edge, sometimes a coin on edge is hard to track down if it's shallow (not every deep). Deep coins on edge will give a 1 - 2 digit number lower that what it should be for that coin (ie quarters 87 - 89) had some read in at 84 - 85 because they where on edge in the ground and down 6" or more.

The G2 / Gold Bugs love silver and gold, you will know when you have hit silver or gold, the sound is much more crisper / louder than a coin sound.

If there is a pocket spill with all the coins on top of each other, again the sound will be louder / crisper and you will get a larger number if it's 2 or more quarters, or an odd number if its a dime and a quarter and so on.

From my own experience with the Gold Bug Pro that I have, I can say that it's just about the best all round metal detector I have owned / used.

The feedback / info that I get from the detector is ...... well, there is no word or sentence to describe it !

 

[Ken in Georgia]

Preach it BH!!! You are right and watch those numbers on the deep targets and under iron targets they tend to bounce quick due to the recovery speed is so fast. Recovery speed is the best defence for trashy areas and this is the best around detector I've ever have had!

I diid not mean to imply posting here was wrong..Just that your question about hot rocks on the gb/g-2 forum did not make sense to me....if your using a different detector ...
When you get to using the g/g-2 you may well find the response different than with the 1266...i've never used one.
And the problem is not really hot rocks...at least not in the mining sense...
Most likely the metal/slag /coke and coal stuff from an area that has seen lots of stuff dumped and burned...
Quite different than the hot rocks in our mining areas.
