I finally detected that old beach club beach on Lake Michigan,and found-One old bottle cap,that sand has been moved on the bottom sooooo much,hard to tell if anything will ever be found.BUT,the water wasn't real cold,I was in for 1-1/2 hours,and it was crystall clear,could see a long way underwater.......This coming LABOR DAY,MRS. PHELPS AND I,are heading north for a nice 4 day getaway,got hotel reserved,and the beach where we will be staying can be detected by those staying overnight,AND,WE ARE planning on hitting a few State Parks beaches,that allow detecting:One I visited many times,1 I visited once,and 1 I have not visited.......!!!!
