I recall in about '83, seeing the first ever Teknetics with target ID. Shown by a dealer at a club meeting, where he had the machine propped on a table, doing demonstrations for the 25-or-so attendees. Bear in mind, that at this time in history, all of us were accustomed to "progressive dial" discrimination . Where .... if you want to loose round tabs, you WILL ... of necessity, loose nickels and so forth. Or if you wish to loose aluminum foil, you WILL ... of necessity ... loose small gold rings. Etc....
The dealer waived a nickel. It gave a distinct tone. Then he waves a tab. It gave ANOTHER distinct and DIFFERENT tone. Then he waved a gold ring. It gave YET A 3rd DISTINCT and different tone. The crowd was spell-bound with awe ! Dollar signs appeared in all of our eyes. With images of digging gold rings till our arms fell off, while effortlessly leaving foil and tabs behind. Doh !
Naturally, as we all know, a million aluminum objects exactly mimic a million gold rings. The variations are endless, so to pick 3 random target examples was not going to show the true array of objects that appear in the field. But at the time, you can imagine how groundbreaking this was
For a look back at the concept invention, here's a cool legal briefing that surrounded the Whites Co. vs. creation of Teknetics. Interesting read:
