I don't know which detector you're alluding to, when you talk about those that "analyze targets" etc... But I can tell you that a machine like the Explorer, for me, has indeed increased my goodie takes in certain situations, d/t it's excellent tone IDs, grid/graphs, etc....
For example, in a certain ploughed ag.field, where we've dug reales and buttons & such: A friend of mine had a non-ID machine, and I had the Explorer. Depth was not the issue, since this was a plowed field. Neither was "cherry picking" an issue either, since we were both in the dig-all (except iron) mindset. However, at the end of each hunt, even though our target counts would be about the same, I'd always end up with more buttons and coins. At first, he accused me of "cherry picking", since I had a tone-ID explorer. But I assured him I was "digging all". So neither of us could understand why I kept spanking him on better targets, while he ended up with the lion's share of can shrapnel, flittly little junk, etc.... Finally, after the 4th or 5th such spanking, we figured it out: In this field, 50 to 100 targets (both age indicators "woulda-coulda's" and modern can slaw, etc...) in a hunt was not unusual. Apparently what must've been happening, is that in a place where targets are prolific, my mind must've been subconsciously favoring the nicer "round" sounding targets, that a good tone ID machine can provide (verses a "beep or no beep" no frills machine). Mind you, I didn't pass anything on purpose (as long as it was conductive), but I guess I subconsciouly was passing things that sounded like chopped up whispy small can slaw, pencil eraser top type lousy signals, etc... You can bet this friend rushed out and bought an explorer right away
That's just one example, and of course, wouldn't hold true for other type hunt sites. I can also imagine that junky old-town turf would be another place where the graphs and tones would help a person play the odds of what to chase (so that they can favor the coin-like deeper targets, and pass surface coins or shallow junk, etc..)
