Just received my new ATPRO last night,assembled it and read the manual quickly.Iwent out this afternoon for three or four hours at local small city beaches.I found three rings,a watch, and about five dollars in coins.One ring is stainless,one sterling and gold,the other is ten carat with two emeralds.I was hunting in pro mode,nothing notched out,iron reject set at 15,sensitivity at max.I had a wonderful afternoon and really enjoyed the ATPRO,I just wish there was a detector that would ID canadian coins.HH John.
