In the past I purchased a really basic Garrett Ace 150 because I was going to be doing some landscaping around the house and being that the house was built basically built on the same site as a previous homestead that burned down I though I might find some old coins and relics. I did find a few silver quarters and dimes from the early 60s (not as early as the homestead) an old watch that had been crushed, probably about 20 pounds of nails, beer cans, pull tabs, glass and ceramics and melted metal roofing. I'm thinking about getting a better rig but no way wanting to spend a grand for this hobby. As Michigan doesn't have a whole lot of historical relics you are going to find on your own property unlike areas where the civil war or revolution war took place. ROI isn't going to happen. Probably going to hit some poor rock piles in the UP this summer and see what copper might be left around after the crushers pulverized the mine rock. Also going to hit my sisters quarter section and look for some float copper as well. What type of equipment are you running? do you use a pin pointer? What was your best find?
