With the author of the videos statement that iron will not be detected in pinpoint mode. My Etrac readily pinpoints to iron, as everyone's will. What will happen is, if you switch to PP and then move your coil over the iron target, you will tune it out, and will be able to tell if there are collocated targets. This is clearly evident at 3:34 in the video. As the author begins to move the coil over the iron target, you will hear an audio response from the iron, and then hear it tune out. It must also be pointed out that for this method to work as shown, the detector must be set to the normal PP mode. Depending on the size of your iron target, and its positioning, if you where to slowly sweep across the area of the two targets where your coil would be crossing both targets, you can still get an iron response. The Etrac does however do a good job of tuning out the iron. In my testing of this method, I did find that careful coil control allowed me to isolate my good targets next to iron without resorting to this method. I do believe that this method will certainly help some increase their finds though, but this is no substitute for careful examination of targets and good coil control and technique.
