I'm overwhelmed at the response I got from you all. Thanks so much! This is a forum of really great people. In my first post, I made it sound like my own yard was the only place I used my detector last year. That's not the case. I actually took it to a beach on Lake Michigan. I wasn't very successful, but the detector did well. My yard is mostly loam with clay underneath. I used it at my parents' house, which is all sand, and I got a lot of readings that jumped around. In some spots, I dug nothing. In both areas, there were a few times when I would get a number, then a different number, then nothing at all. That's the only negative I have found so far.
One other place I detected was an old cavern in southern Ohio. In the early 1900's, there used to be a merry-go-round out in front of it. I thought this was perfect. Contradictory to an earlier statement in this post, I got solid hits everytime in this wet sand. Unfortunately, they were all beer cans that people have buried.
I went ahead and ordered the small 6" coil. It'll be great to have on hand as I get out this spring/summer.
One other question I thought of... I've been tempted many times to stop and detect old abandoned homesteads, buildings..etc. I haven't given in to temptation because I want to follow good treasure hunter code and not make a bad name for us. So, when you're driving down a back road out in the country somewhere, and you see an old house or great area to detect, how in the world do you go about getting permission to detect? In the county I live, the auditor's site in online, so I can lookup a residence and find the owner. In my parents' county, where there are many opportunities, I don't have that luxury. I guess I'm curious of any tips/tricks to locate property owners.
In summary, yes Monte, I could definitely use some more experience. At the same time, I did use it a little more than I may have made it sound. Again, thanks everyone.
