I have recently purchased a 5 inch F-75 coil for my F-70 and am quite pleased with it. While air testing on the coil I am amazed with the detector getting readings of 9 to 12 inches from a penny up to a quarter. This would mean to me in the real world I should expect amazing depth with this small coil. What are some of the deepest coins some of you users have found with this coil? Thanks in advance
