So I get a nice 73-85 hit and an old colonial ford site and start digging. MD indicates about 4 inches. 14 inches later and still nothing but a solid 83 right in the middle of the hole. Ground is too hard to continue with my lil' digger so I bail with the hopes of coming back soon with a shovel.
Question #1 - My coil was at top of hole and my MD indicated the target was 1 inch deep!! How is that possible. And no, target was not on sides cause I expanded the hole diameter and the target remained the same.
Question #2 - About 12 inches down I hit some brick fragments and what appears to be a small piece of coal. When cracked open it has that smoothe, black, glossy character - like obsidian... except this rock is more brittle.
Deductions?
