Tried my new/used Excalibur a few times. I got a nice threshold and would start searching and suddenly the threshold tone would go to a deep growl. I think it saw iron. If I moved the coil towards my aluminum scoop, it would reset the tone to the nice high tone. I did find things with it and think I know the clear beep of a 'good' target, but am curious about the deep growl. With other detectors I've used the low tone is iron, but after removing it from the area the detector resets to the 'normal' threshold tone. The excalibur didn't do that. Ideas on what's going on?
