If you could have any detector you wanted, money was no object, what detector would you pick? What treasure would you go after. Time is no object either. Dream on!

By acquire, we are talking five finger discount, right

Imagine a radar generated picture of a gold ring projected on a LCD screen, you'd never have to dig a pulltab again! Deep silver coins would be obvious coin shaped images, deep iron nails with strong halos would be obvious visually.
Frankn said:Eagle Down, I think you hit the nail on the head. I mentioned it in a prior post. I was trying to explain to a new member how the detector knew what metal was down there. This is just a theory of mine, the manufacturers don't tell. The transmitted frequency is reflected back with the resonate frequency modulated on it. Kind of like a radio transmission. The detector reads the resonate frequency to identify the metal. Needless to say, the process is far from prefect ed.
