Hi all, does anyone on this post have any good adjustments to the MX Sport to work an area with a lot of hot rocks and iron. There are good items to be found on this old homestead site but my detector goes crazy because of all the iron in the ground and its very mineralized. I'm using the smallest coil for the MX Sport, the DD coil I think its like 6 or 7 inches or so. The setting I was using was High Trash but it's still working quite erratic any ideas and help would be much appreciated... Thanks
