Early target ID through audio differences

[Batch]

Hello all,

I am re-posting in this forum in hopes of finding an answer to put my mind at rest! . About 35 yrs ago (1977 I'm pretty sure) a metal detecting magazine (I can't remember which one) that ran a small feature on a young man (teenager?) that could - using his ears and the audio output of his detector only - identify nickle, dime, quarter targets with excellent accuracy.

I know it is a long shot, but does anyone remember this? An even longer shot, does anyone have a copy of that article? I'm curious what that THer is doing now.

Thank you in advance for any information you can provide!

P.S. When I managed a couple of music stores back in the early 80's, I hated customers who did what I just did. They would come in and say, "I heard this song on the radio. I don't know who sings it or even the name of it and in fact I can't even remember exactly how it goes but can you tell me if you have that album?" <LOL>

Can't help you on that, but I can nail a pretty good percentage of correct calls between slight nuances in the sound combined with a bit of discrimination thumbing. It's taken me quite a few hours of detecting, but once it began to jell, it's gotten easier and more often accurate. The nuances just have to come with practice. I couldn't just try to describe the slight differences for another person, they would have to hear them repeatedly as they detect and develop the feel for themselves. I wouldn't say I could do the same with a different machine right off until I got to know it, either.
