Been detecting an 1897 yard. Not finding too much. I have been running 6x9 cool but switched to stock coil. Ground balance is regulating at 72-78. I’ve tried that but it is the lowest I have seen a gb so I have manually tried the 80’s. But my problem I’m having is my vdi numbers seem off. Clad pennies are consistently reading 88-93. With numbers like that, I will always dig. I did get 1 silver dime at 82. What is making pennies read so high?
