This is an interesting argument. You would think that iron mask would have no use in the all metal pinpoint mode but I'm not so sure it's as simple as that. The iron mask feature is different than the normal discrimination range of the detector and is achieved differently. You can see this with the Sovereign GT when switching between iron mask on and off. Turning iron mask off changes the detectors sensitivity to ground minerals, iron and even electrical interference which leaves me to believe that the difference has more to do with it's use of or change to certain frequencies between on and off as opposed to just filtering through normal discrimination.
