I was testing my F5 with the new 11" DD coil and wow does it separate targets. In the picture are 2 rusty nails a quarter and a dime (both clad, oh well) and they were all in the same hole. All 4 targets were within 3 inches of each other. I could hear lots of targets in a short space, but moving the coil slowly back and forth just an inch each way it separated each target, it sounded off great on the quarter with an 80 and the dime with a 70, the nails were giving 90's and bouncing around. On the dime and quarter I could not always get a solid hit in every direction but when it sounded off it was the solid pop you get on coins with the F5. Nothing valuable here but it just shows how good the F5 with the 11" DD coil can separate targets.
