Whats In Your Coil?

We've had a ferrite inside our coil all along it looks like. :tongue:

It's not in the photo you posted of the coil being tested in the Minelab bench, wonder if it's just an FCC compliance thing as some mentioned in earlier threads. It seems to be covering a wire junction or solder point in the middle.

Anyone know what that square thing in the GB2 coil is?

Also, I hope my Deus coil goes bad at some point just so I can take it apart without worry about breaking it and figure out how they crammed a whole detector into that tiny amount of circuitry. There must be more shielded in that tube thing.

The GB2 coil has a square windings connector. The 'fireworks' are 2x ground-shield sprays of light gauge wire to attempt deadening of ground noise. Always a difficult thing to attempt when utilizing concentric designs in the goldfield soil conditions. the rest of the loose wire is excess tuning wire to reach the correct induction and frequency match. Ive seen much cleaner versions of GB2 coils than that...musta been a bad day when that one was made lol

Steve 'looked' inside of a coil a few years back:

Thanks for that link.. I don't have the balls to open one up unless it's broken of course. 2014 was the year that I got hooked on this hobby..

Thanks for starting this thread and sharing wonderful insight into the inner workings of the sensing head of our various detectors.  Very educational.  In many instances there is much more happening inside the coil than meets the eye.  Do you happen to have any images of any of the White's Goldmaster 24k coils?  Just curious. ?

Thank you for that strick! I've been waiting for these ? It'd be good to see sometime if the 17" is fully spiral wound.
