It's me again. Forgot to ask a few other questions about the 505. I watched the learning videos and have been watching others as well as reading but, what I can't understand is: If gold has the lower tones of say a nickel or iron, how does one know what is really down there? Does the target identification read a gold ring as a nickel or other iron and does it indicate as such? Same question for the higher tones for silver/clad, how do you know if it is a ring or a coin? Do you all just dig? As for the lower/higher tones, how do you discriminate to weed out the iron and recover the gold?
Thanks all.
Thanks all.
