Build a Magnetometer for 3D Ground Scanning | Ultimate DIY Metal Detector Kit Guide Stop buying expensive hunting gear and learn how to build a magnetometer for deep-ground anomaly detection. This comprehensive guide covers everything from unboxing your magnetometer kit, configuring magnetic field sensors, to assembling a dual-sensor gradiometer kit. We will show you how to make an Arduino metal detector that functions as a 3D ground scanner and high-sensitivity gold detector. Discover the electronics behind professional geophysical tools, filter out high-frequency noise, and build your own custom metal detector kit for finding cavities, tunnels, and deep buried chests. Using advanced magnetic field sensors (FLC100 / FLC101) combined with an Arduino and a 16-bit ADS1115 ADC converter, you can build your own DIY gold detector and cavity scanner.
