Newbie - Metal detector sensing something inside a large rock

[killrz]

Hi all. I just started metal detecting 7/10/2012. I purchased a White's DFX 300 to start off, and so far so good. I've done a ton of research about metal detecting, but I'm having an issue finding information regarding a rock I happened upon in the woods yesterday. My detector is going absolutely nuts when I scan the rock, and I'm wondering if I should crack it open? Other rocks in the same area are not setting the detector off at all, but this one is and on every type of default setting the DFX offers. So is this worth cracking open? I do realize there is high iron in New England where I'm from, but I'm very curious.

oh yeah: If you all vote to crack the sucker open, is there a preferred method of doing so?

Thanks!!!

It may be a geode. Sometimes these have crystals and/or minerals inside them.

Ok cool. Thanks for the reply! The rock is pretty large; I would say it's around 100lbs. Any suggestion for cracking it open?

A sledge hammer and a wedge might work. I've never actually split one open that was that large. Most that I find are the size of softballs, but I have seen some that large already split. I've just never done it.

Thanks that was my first thought too. Well I'll post my findings when I break the sucker open.

Good Luck!

Show us a picture of the rock, then smack it open !

I think you're too late on that request... I can see him sifting through a bunch of pebbles now

Don't worry guys I'll take a pic before and after.

Since your taking requests...I would like to see an action shot of you in mid swing with the sledge hammer...

Make sure you wear your safety glasses.

I think its whats called a hot rock,My DFX picks up some rocks that have iron in them.Good luck whatever you do .

It could be a meteorite, they're usually full of iron, so don't crack it open just yet! Do some research on identifying meteorites...and post a picture of it first.

EDIT: OH! I almost forgot to mention the Meteorite forums here on TreasureNet! Take a picture and make a thread there about it. Also, see if a magnet reacts to the rock.

Move a compass past it to see if it is iron. I found a large magnetic rock in VA once.

IF you do cut it open save yourself some hassle and get an Angle Grider. You can pick them up pretty cheap at Home Depot or Menards. Then But a Diamond Tipped blade (probably will cost more than the grinder haha) and cut it with that. Thats what they use for cutting boulders to fit landscapes and stuff. Well they use a bigger saw, but same idea. Good Luck, post some pics.

Hello everyone again, and thank you for the massive input...much appreciated. I did do research on meteorites as part of my pre-metal detecting research, and coins, and rings, and relics too. However, this was definitely just a big rock. So, I purchased a sledge hammer, and swung away at it 1 or 2 days ago, and all I saw was what looked to be a rock very high in iron. However, I didn't have my metal detector at the time, so I am going back to scan the rubble pile. I'm doing this, because my DFX pin-pointer function zeroed in on a target within the rock, and did not go off when pin-pointing other sections of the rock. I know it's probably silly to continue with the rock, but I have enjoyed the hell out of figuring out what is inside it. Call it a learning experience I guess. I will also try the compass trick mentioned in this thread.

The kid and i left a large boulder found in a barn foundation,it rang up silver. To big to be reading through, partner wanted to look under the beast but left it alone.(hope she doesn't,t read this thread!)if your ever in area with your sledge,look us up! H.H.

No, no; continue smashing that rock, I know it's there Once you pulverize the rock and the dust settles ( I do mean dust if you are really pounding it) then the treasure should appear. If not, at least you'll have arms like Popeye
