I just received my MX7 Tuesday. Today I took it out for a short hunt at a local school field. I found 4 quarters, 2dimes, 1 nickel, 2 zinc pennies and 1 copper penny. One of the dimes was a 1964 Rosie. The 64 Rosie was about 6" down in the ground. I was using the 6x10 Sport coil. I was pleased with the machines performance. Here are the settings that I was using:
