Every detector I've ever used has this falsing flaw. It is frustrating but until a better system comes along and it doesn't cost you the mortgage on your house to buy, then we do what we have to do.

It is very difficult to overcome the laws of physics. Iron's response to a time variant magnetic field is direction dependent. Non-ferrous materials respond in a direction-independent manner.

Ferrous materials may sound good in one direction, but will show it self to be iron if swept in a direction 90 degrees from the direction it sounded good. Should sound broken in angles in between.
