Roots and rocks

[sushidingo]

I recently bought a coinmaster gt and took it out yesterday for the first time. I had nails and horseshoe options discriminated. I kept getting hits on roots and rocks. Every dig was a root or a rock. I buried a quarter about 8' and it picked that up no problem. I was wondering if anyone else has had this issue. Could there be mineralization in the roots or the stones? I detected a small stream and found a charcoal stick and a lot of the larger stones sent the dectector into overload and others rang between -70/-95. Juat looking to hear some options of what could be happening with my detector thanks.

Sounds like you may have been in an area full of hot rocks and/or were running too much sensitivity.

Hot rocks?

HOT ROCKS:
Hot Rocks is a term that applies to terrestrial minerals that register (hot) on a metal detector or are 'attracted' to a test magnet or may visually appear metallic or meteoritic.

Basically, high mineral content rocks, for a variety of reasons... almost all of which annoy detectorists. To avoid, you might need to lower your sensitivity.

That or your rocks are filled with gold. If it's quartz, crack one for sure! And if you have a pinpointer, that'll help, too.

Quite likely though, it's only mineralization. Lower the sensitivity to put things back in line.

Cheers,

Ok thanks. What about the tree roots? Similar issue, turn down sensitivity?

Possibly. Tree roots are a funny thing, as they'll absorb minerals. I more strongly suspect they are hiding something small. I've found lots of pellets at the base of trees (lead pellets will beep as they're not iron), coins a-plenty, and other objects that fall out of people's pockets as they sit under the tree. This is where a pointer tool comes in. If you're getting an actual strong signal from an actual specific location, it's not likely to be the tree root.

Depending on whether or not the digging/cutting will damage the tree, sometimes I leave items in the ground. I've had signals below roots big enough to require an axe. Those will have to wait 80 more years for the next detectorist.
