Minelab's GPX6000 on the hot rocks

[@Maxkil]

I really want to go detecting for gold

Hi. Same problem with PI in areas where a lot of iron hot rocks exist. My SDC2300 was screaming, couldnt use it. Surprisingly the Gold Monster 1000 in discrimination mode can see those hot rocks, show the sign towards iron but not making any sound. I was able to detect with a VLF.

That’s some really hot ground

Hi Phil, might be best to try the 14" DD coil in that ground, it's a fantastic under rated coil and should handle those rocks better than the mono.

Yes, correct. I have put it on when the hot rocks are a bit noisy. Still sensitive to small targets and will ping deeper bigger targets. Will top out about 10” on a 5g where the 11” mono will punch a bit deeper. Mind you we are in Leonora, that ground shown might be more difficult to balance on. I know I can get mine to run dead silent on the laterite and basalt. I bit noisy on the magnetite iron stone. I wonder if the 6000 in this clip has a problem. It has been an issue on the early machines. Although I have spent a fair bit of time with two of them without issue.

@@goldfools5445 Yes the DD does make a diference on bad ground but these ironstone rocks give such a sharp signal there seems to be no fix for it on the 6000. This is my new 6000 supplied by Minelab under warranty recently. The old machine was trouble from day one but I put up with it for nearly tow years but after one repair and four coil failures Minelab replaced the whole unit and this is a much better detector.

When on the patch at Naneen we had two 6000's and tried both coils. The GPZ7000 and GPX4500 ran reasonably well over the same ground where the 6000 couldn't be used.

That's why I love my zed Phil. It still gets noisy, but in some ground the 6 is too sensitive and thinks everything is a target

Each to them selves, hot rocks. I just swing very very slow and not to use the stock coil. Try hunting those places before sun hits them.
