I went to the river today to try and find a man's wedding ring he dropped while working around his dock, but the water was too deep for my chest waders and too cold for wading without them. Even tho some young people were swimming, the water was too doggone cold for me. I found 9 cents and a marble and quite a few pop tops and beer caps. I thought hunting in pro mode zero with the iron audio on would help me miss some of those bottle caps, but I was wrong. I couldn't hunt the side I usually hunt due to the swimmers and just worked an area that didn't offer much, but it got me out of the house with my at/pro and that's the first time since 3/16 of this year. The pro mode did find a penny at either 6 or 8 inches and I just barely heard the signal on my headphones and started not to dig it, but I definitely will try the pro mode zero setting more than the standard settings from now on. I got a sweet sound on the nickel and it was a 53. HH.
