Hank, inland lakes or great lakes? Actually ANYWHERE. People swam EVERYWHERE before air conditioners. I hit as much of the shoreline I possibly can. Sometimes I hunt fast till I start finding targets and sometimes I just go slow and go an hour without a beep. You NEVER know where a old public beach or an old church camp was and it could actually be someones back yard now. I have found gold rings on dropoffs and no other targets around. I found an old camp or something that is now behind a house BUT after 8 gold rings and numerous silver coins and religous medals something besides a house was there thats for sure.
If you want new jewlery its in the roped off areas, BUT I like the old things also. A beach I discovered last year which is now noplace anybody swims gave me 4 gold rings and 34 pieces of silver. This beach I have been hitting recently is an accociation park and the house to the right of the park gave me permission to play in the lake, which means I can go ANYWHERE. There are a TON of long lost beaches, never to see a swimmer again. Those are my absolute favorite places to find. Another one of my favorite places to stumble across are where old swim platforms made of 55 gallon drums were anchored. I have an absolute hayday with those areas. Hope this helps and good luck. OHH and if your in Michigan forget the water. Nothing more to be found here.
