That video describes exactly what I was trying to get across with my post. Just a simple thought. Put ALUMINUM in the same tone class with iron. Low tone= ferrous target and also equals aluminum. Everything else high tone. Forget the numbers ID for now, maybe that could come later.

Size, shape, depth, orientation, nearby metal, mineralization, and heck sometimes it seems like even planetary alignment can affect a target's ID and sound. Sure, a flat lying round gold ring and a piece of jagged can slaw are pretty easy to differentiate with even a bit of practice using methods like edge pass rejection and quick out. A Tesoro is an excellent detector to learn those techniques. Bobbing the coil can help gauge thickness as well, particularly on a TID machine. But throw in any of the above mentioned factors (particularly depth) and all bets are off. The more I realize this, the more junk I dig, and the more I'm rewarded with goodies I'd have otherwise missed. So no, barring some as of yet undiscovered technology aluminum will remain a pain in the a**.

For most detectors, this is just a matter of cranking up the disc until all the aluminum is gone. If you want them to also grunt like a nail, some detectors can also do this. Obviously you will also say 'so long' to nickels and most jewelry. In some situations, that might be the best you can do.

No, I'm not. My bad. The (5.32) written by myself had to do with 5 minutes & 32 seconds in, in my video!
Not TID's. Nothing to do with that. Sorry for that confusion!

Oh, by the way, I never 'notch numbers on detectors', but I do 'cherry pick' TID's
In this case, what I wanted to say was I would normally ignore 12, 15 and 18 when coin shooting.

Dan, yes, there is an ability to tell concise equal-sided objects, versus elongated / irregular shaped objects. Granted. But .... praytell .... what good does this do when trying to discern gold vs aluminum ?

I'm still not talking about gold. If I was, I'd agree with you completely.

JmaryT, "smoothness" or "raspy" or "sharp", etc.... don't even need to be learned on any machine, to pick coins out of trash . Assuming you meant higher conductive coins, then it's simply a matter of adjusting one's discrimination control to knock out the lower #'s.

Des-D : Whether a person does the "notching" by control settings on the actual machine, or does it by "ear" (cherry picking TID #s he's seeing cross his screen), either way : THAT'S STILL NOTCHING. You can elect to let the machine classify #'s as to what sound they give (or nulled out, or whatever), or do it by ear. Either way, it's still notching.

i don't disagree,however,i am referring to being able to "tell" the difference from"tonal quality" of various hits,REGARDLESS of where the discriminator is set! my apologies!..'clarification" was necessary!..to be frank,it's what i love about the analog responses of a single tone tesoro.

(h.h.!)

Target profiling using every feature available to you is your best offense against aluminum trash.
