New Metal Detector Book!

[Fred]

Hi !
Just discovered the existence of this book, congratulations to the authors !
Probably the first book that technically reviews LRL´s with an open mind and a technical project.

I have plenty of high quality multiturn verniers knobs, just missing everything else for now

Thanks Geo. I seem to remember Carl telling me that he was able to trigger the Mineoro FG80 with his garage door opener.

Hahaha, that remind me some funny moments here on Geotech...
