Can anyone share what kind max depth they are getting with the sunray 5 inch coil, I just bought one from Bart a few weeks ago, found a few silvers with it, but they were not very deep, as I was in the woods. They don't seem to sink as much in the woods, as in the parks, etc. The silver in the parks and such hase been mostly about 7 or 8 inches. Maybe someone has fooled around with one of these in a test garden, or hit some fairly deeps coins with this coil. I want to try some more TTF hunting, I would think the small coil would be the better coil to use, but I have been wondering how much depth I am giving up droping down in coil size???
