Has anyone done any testing concerning how much detection depth is lost if a coin is in the ground on-edge , versus lying flat ? I use a screwdriver both to locate and remove coins..it occurred to me that out of the thousands of coins I "popped" up last year, I can't remember a single one that appeared to be on-edge when I first hit it with the screwdriver..best as I could determine, they were all either flat, or nearly flat.." I F " it's the case that on-edge coins are nearly "invisible" to a detector, there must be a lot of coins left in areas that have been extensively hunted...no law, that I know, saying a coin has to go into the ground flat..another question is whether there's any reason to think that an on-edge coin might move to become a flat target over time...If a MD'er changed the angle of the search coil with the ground, i.e. from the parallel 180 to an acute angle, would that give the search head a better surface to detect with on-edge coins ? Any professors out there ?...RR
