This is being overthought - It is a simple tool to be used as the owner sees fit.
I remember my 1st pinpointer about 15 years ago when they were pretty rare, I was blown away, instantly saw the beauty and fell in love.... Had,a couple negatives though, for one is was pretty cheaply built, even with that thing it was hard to resist doing some aggressive probing and digging with it once the target was located, and that would snap the neck sooner rather than later. Another, it was shaped exactly like a pistol, which caused some concern at tot lots I used to detect when my kids were, well, kids, even though it was yellow & white .
Then I upgraded to a "Sherlock", its body was about like a deck of cards and had a stubby little neck, much less prone to snapping but not much reach and a bit awkward in deeper holes. Used that until the wave of modern ones we know now started coming out.
