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.

When I got started, there was no 'Discrimination' as we came to know it. Metal / Mineral detectors sounded off on non-ferrous coins, rings, etc., and ignored most iron to include those magnetic Bottle Caps. The early 'conventional' TR's were enjoyable to hunt with in BC infested old picnic groves where old coins were aplenty!

Then hobbyists started fussing about the lower-conductive trash, such as foil from mainly cigarette packets, that was a problem back then, and engineers came up with Discrimination to reject the lower-conductive junk, such as foil and then we got those blasted pull tabs to deal with. That increased the Discrimination range to knock out lower-conductive non-ferrous trash.

The subject of 'Notch Disc.' ... as our momma taught us ... didn't come along until Coin Hunters wanted o just reject Pull Tabs and get the Nickels and lower-conductive gold jewelry. But going to the 'improved' Discrimination meant we started to get good hits on those magnetic Bottle Caps, and things got worse when we 'advanced' to VLF-Disc. That meant Bottle Caps started giving us more fits with a higher-conductive reading.

I have never been a big fan of 'Notching' as we initially learned it, but have tried to get more folks to understand that 'Notching', as you well described, includes both Audio Tone ID and Visual Target ID as well. Once we start to pick-and-choose what target ranges we want to search for and ignore, it does get into a personal thing about decision making.

One thing I do know is that when it comes to Bottle Caps, the favorite detector for me to use in such a trashy BC location has been the White's XLT. The Bottle Cap Reject on it is adjustable enough and works well enough that I feel it is still unmatched by today's modern digital units. I did quite well in several old picnic groves nabbing a lot of coins and ignoring the majority of the BC's with the XLT.
