I got the F75 LTD for park hunting due to weight and coil selection. EMI has been a concern with sens. set over 30 in most places. Last 2 sites I have been to I ran 1f and it works really well for me with both coils but it really works with the 5" coil. Can run sens. at 90 and fairly stable. Decided to go to a field that is one of the oldest still being used and has given numerous gold finds to me and my friends. Used 11" with a sens. of 50. {looking for recent drops in grass} disc 8 and DE mode. When on a good target I get a solid signal. 3g.14k-p band. Not sure if its a petit ladies wedding band or a kids gold ring. #3 for the year. Going back with 5" soon and crank it up. I was getting some really deep repeatable signals. I didn't want to go to deep on a this field but temptation may get the best of me. A few silver coins have been taken there a couple of years ago so a chance for some silver is there. Thanks to Revier for sharing his F70 setting. Thanks for looking JR
