Does anyone know roughly what metals the dial settings represent?
The dial starts at 0 and 'all metals' to 5. The instruction manual only says the further to the right you put the dial the more undesirable metals such as iron will be ignored. Is there a more detailed answer. For example say at position 3 will gold or silver be detected or ignored.
Your main metals are iron, brass, nickel, copper, gold and silver, aluminium, lead, chrome etc.
