Yes the Explorer SE has an all metal mode. It should tell you how to use it in the owners manual or in Andy's book on the Explorer and E-trac. One way yo get to the all metal mode is to go to the iron mask setting and clear all of the iron mask off of the screen this will put you in All Metal. Hit detect and you are ready to go. Most people like to use a ferrous setting so that all metal will sound off in a low tone.
