SD2100 with 2 modifications. I look for ironstone patches especially. There is one patch that is pure Ironstone that has a conglomerate patch in the middle of it that sheds gold.
I remember in the early days I had a garrett Deepseeker that you couldnt even put the coil within a foot of this patch, the SD just managers to handle this patch, only just..
Each time I get gold on it though even after it's been pounded over the years. Very hard to detect so I think most prospectors miss alot of the gold. Very much ironstone, and magnetic black sand there.
