Yes my Youtube channel also has video instruction on building a plain mono-coil as well. Happy Hunting.

So just to clarify, The coils are wound, then taped with Scotch 33, then sheathed with the Davis Industries tubing, then shielded, then wrapped again with Scotch 33 and lastly epoxied with slow curing resin. As such I have zero concerns that there will be movement when bumped. Glad that you enjoyed the video. I truly enjoy building PI machines and the associated accessories and the videos are an instructive sideline that are an interest as well. Subscribe if you so desire. Cheers

For anyone interested in seeing how a Dual Field is put together, I recently did a video on making one after reading a lengthy thread on the Geotech Forum. Cheers
