It was only in the 80's today so I gave it a try for 2 hours. Had permission on a older home I've been saving for awhile. Used my F75+ today with the Nel Sharpshooter coil. I have used it some this year and like this coil. Settings were sens.90, 3H tones with Iron and foil notched out. One thing for sure is it sure pays to get on sites which have not been hunted or not much. I was able to dig a worn 1892 Barber Quarter, 1914 Barber Dime in great shape and also a no date Buffalo as well as 6 Wheats. I'll be back for sure as I only covered the front yard some. Probably will try the stock 11in. coil next as it may go alittle deeper? Deepest coin today was around 7-8 in. I took a pic but it turned out poor.
