Jeepers. We use variations of notching all the time. If you're using 2, 3 or 4 tone programs to hunt, you're notching. Iron audio is notching, audio and visual target ID is notching. We can skip digging anything we see/hear at anytime. When I water hunt, I set up my detector to accentuate lower conductors in certain segments or the scale to make sure I hear them and the signals are brought to my attention. That's notching.

We NOW look at the target ID scale, ferrous to conductive and back again, as the entire spectrum of metallic objects. We can eliminate (audibly & visually), minimize or accentuate any segment on the scale we want. Depends on what we're looking for specifically or if we're just searching for ferrous or conductive targets in general.
