after re-reading iron mask in andys book and reading about the tones on the f75 forum it made me take another look at tones onthe se.i put on stock coil and tried two deep targets (dimes) in normal the target would not read..set my gain at five and response to long.in came that sweet sound.made me super happy. the deeper coin sounds better than the shallower coin.then played with iron mask and sensitivity and don't have that part down real good,but higher sens did do better there.i think there must be more trash at the shallower coin. they are at 8'' and9''. just play with and be afraid to experiment. low 70's and cloudy here today.sorry you guys up north are socked in,just keep readin.hh
