Once you have assembled this SK-9904 Metal Detector Kit, lets take a look at how it works. It is related to the early army mine detectors and the sensative solid state metal locators of today. Not only is this SK-9904 Metal Detector Oscillator educational, it could get you started in a fascinating new hobby! Its easy to construct and fun to use.

This SK-9904 Metal Detector Kit is an oscillator and radio transmitter. It transmits a signal to a nearby AM radio receiver. The radio will emit an audio signal or tone. The frequency transmitted to the radio (and thus a tone produced) varies as the metal detector is brought close to a metal object. With no metal near, a tone of a particular pitch is heard. When the metal detector is is brought close to metal, the pitch drops and a difference can be heard in the tone.

This kit comes with step by step instructions, Explanation of Operation, Reading Comprehension Questions, Circuit Board Schematic Diagram, Pictorial Diagrams, and there are also Troubleshooting Instructions.
