New Metal Detector book!

Thank´s a lot Qiaozhi.
All is working how it should. The problems were the samplepoint was set a little bit to far away and my ground in the bucket was not compressed enough.
Now it´s time for real fieldtest.

Wow, what a great detector.
After going on a field and setting GB, the Raptor (with 11" DD coil) has outperform my Explorer SE (with 12"x15" DD SEF coil). The Raptor is rock stable, with extrem good target pinning (make a x with the coil) and very good iron-discrimination. I found only some solid iron-part´s, most a sort of ring, that came through with a good sign.
Thank´s Qiaozhi and Carl for writing the book and development the Raptor. And thank´s also to silverdog for selling the PCB.

Thank you for the feedback. The iron rings always get detected due to the shape, as it enhances the eddy current flow and creates a strong receive signal with a lot of phase-shift.
If you find anything valuable, please let us know.

Do you have any photos of the finished detector?

Congratulations to constructors and remaker?

Does silverdog sold Raptor kit or even PCB?

Thanks. Ordered.

Seems it is limited in stock, I was not allowed to order 2 PCS of those PCBs

Here it is.


The stem and batterycase is from the Garrett GTI 2500.
