Overall, I highly recommend "Inside The Metal Detector" to anyone interested in metal detecting. The book is well-written, informative, and engaging, making it a must-have for anyone who wants to get the most out of their metal detecting hobby.
By visualizing this on an X-Y graph (a feature popularized in their technical breakdowns), the "Discrimination" knob suddenly makes sense. You aren't just "turning up the power"; you are setting a phase-angle window. The PDF doesn't just tell you how to hunt; it teaches you how to tune an orchestra of invisible waves.
