Quite wrong! I was never a nerd. Being a family man, pulse induction was, and is, only a part of my life. Still have a beard, by the way, but a little more trimmed.

Mine also but you might notice that the second half is repeated at the back some sort of printing error (might make it worth more).

Mine seems to be ok. Page numbers go from 1 to 175. No duplication of pages.

I've just ordered a copy of 'Metallortung mit Detektoren' by Wolfgang Schuler from UK ebay for £5.19 with free delivery. There's still one copy left if anyone else is interested.
Can't have a hole in my collection.

The book has just arrived.
Looks like a new copy and completely unread. Lots of photos, diagrams and descriptions, but no schematics.

Myself taking readings from Claus Colani's PI detector in 1967. A technician is positioning the search coil on the 10m square nylon grid placed on the ground. The grid is divided into 1m squares with 0.5m markers.
