Went back to spot 2. It has been raining all week and the lake levels are rising. Lake I am working is about a foot over it's normal level. More rain coming this week. I got home from work late and only spent about an hour digging before dark. Found $1.72 in clad and two more silver rings Bottom is clay with a little sand over it. I have an old stainless scoop with a galvanized pipe handle that I hauled out for the day. It worked so much better than my all stainless scoop. The weight of the pipe handle lets the scoop really cut through the clay. I use a floating screen so that I do not have to mash the clay out of the scoop. I just dump it in the screen and break it apart. I wave the pieces past the coil until I find the one the target is in. Sounds like this takes a lot of time, but so far it is the fastest way I have found to work the clay bottom without scuba. When I dive, I use a three pronged weeder and scrape the bottom until the target moves. Then it is a matter of picking it up.
