I bought the F70 about a year and a half ago. I haven't used it but maybe an hour or so...and haven't found a lot. I did not know how to navigate the settings very well. After reading alto on these forms (downtime at work), I got it out last week with my daughters and found lots of clad right in my own little back yard. When I first got it I dug several holes with nothing in them and lost confidence. I have it back now a little and want to use it on some of our land. We have approx. 1000 acres about 20 miles from town with 4 old home sites on the property. The home sites are mostly 1800's possibly very early 1900's with one of them. What settings should I use. I would love to find very old coins...etc but don't want to turn down any old relics either...maybe a silver spoon...or whatever. Thanks for the advise!
