I went to the river for 2 hours with the at/pro and the 5 x 8 coil and pulled a sterling silver ring and a copper ring plus 17 coins for a total of $ 1.63. Enjoyed myself and had a hard time getting out of the water, but it was great. I usually prefer the stock coil at the river, but it is so trashy, the smaller coil plucked these two rings out amongst the trash. Hope after the 4th of July, I can hit it again and maybe detect longer. Will post photos later this week when I have more time. HH.
