I've read where Fisher has hidden secret setting in the F75. Now some of these we know already, like, disc below 5 or above 20, puts the F75 into a more sensitive mode. But the one I've read about is in all metal mode with the threshold set at either -2 or +7. If anyone in the world knows, please explain.
