Attach a 9v battery (Vin pin on Arduino) and observe that the unit has started up ok (Arduino flashing lights) Place the search coil somewhere away from metal. Press the calibrate button. Each LED should light as it calibrates each of the 5 coils. Move metal close to the search coil and the associated LED should light.
The F-Pulse is a great pinpointer with a lot of strength. It has a great detection depth, with silver coins often found at 3.5″, and its ability to remove signals from ground minerals as a pulse induction pinpointer is a huge plus. To tuning for ground phase match, simply press the point into the ground and retune.
