| Problem | Likely cause (per Overton & Moreland) | Fix | |---------|----------------------------------------|-----| | Constant beep/no null | Coil misalignment | Adjust RX position / add trim cap | | Weak depth | Low TX amplitude | Increase TX voltage or coil turns | | False signals on wet ground | No ground balance | Add ground balance pot or auto circuit | | Poor discrimination | Phase reference drift | Use crystal oscillator; stabilize supply |

As they lifted the chalice out of the ground, the forest seemed to grow quieter, as if the trees themselves were holding their breath in reverence. | Problem | Likely cause (per Overton &

It explains how induction and eddy currents work, teaching readers why a gold coin "screams" while a nail "grunts". the forest seemed to grow quieter

His work explained why detectors false on wet sand, how ground balancing actually works, and—most importantly—how to build your own from scratch. how ground balancing actually works

(simulating Overton & Moreland’s experiments):

The detector measures both amplitude and phase of the received signal relative to TX.
