The AT Gold with the 5" x " coil is a great machine for hunting the waters edge, where there are multiple targets and a smaller coil with great separation is needed. You just have to listen to those high beeps for the silver and copper. The ATX is good in the deep water where more deep targets exist.
I dug up a nice old vintage fishing tackle. Putting stainless steel shot in a tunmbler with some dish soap is an excellent way to clean silver, gold, copper etc. finds
Silver coinage from water hunting is always appreciated. The 1937 variety die had a smaller date, hence it wore down quickly. They enlarged the dates following this year.
