Yes, I did lower the iron volume. Ā I had forgotten about that. Ā It got a little annoying at time when at 10. Ā I think I put it down to 7. Ā  Even though Iā€™ve hit that site many times with the 9ā€ coil, there are instances where a larger coil will unmask a target when the smaller one wonā€™t. Ā And vice versa. It depends on the distance between the good target and the junk target and the width of the coil. Ā I learned this from one of Loren Lemkeā€™s (not sure if Iā€™ve spelled his name correctly) vid
