For the modern detectorist, revisiting these PDFs is not just historical curiosity; it is a masterclass in signal processing, analog design, and the physics of eddy currents. The next time you swing a coil over a buried treasure, remember that the fundamental principles inside your machine were likely discussed, diagrammed, and perfected in a Geotech forum post by Overton or Moreland.

In the late 2010s, Carl Moreland updated his designs. The "Surf Pi" evolved into the "Surf Pi 1.2," and later the "Cointrack" series. However, the original PDF remains the canonical text because it includes the theory of operation —the "why" behind every resistor and capacitor. " and later the "Cointrack" series.
