Son M this week returned a metal detector to me, ahead of his going overseas. The coils are pictured here. It is a design by the late Andy Flind, who was my favourite electronics designer with Frank Rayer -- I built this off his design. This metal detector has been said to be one of the best, if one knows how to use it. Andy and I became cyber-friends. He had a complex TENS design published, and I wrote in: not like that, like this. My own design was published, and the two of us stayed in contact until his death.
