Done and sorry.

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.

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.

A nerd masquerading as a tough guy.
Typical look of the sixties and seventies, last century.

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.

133 onwards is some sort of addendum on mine repeats some parts with corrections including the pictures....

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.

Somehow i simply knew there were some Slavic roots there!
