I found, ordered and tested my kit probe. It came as a kit from Velleman Part# K7102. Anyway I have no experience with electronics so I thought this was a bad idea. It was idiot proof. I read their .pdf file online [looked at the pictures]. Before long I was air testing my new probe. It has an LED that gets brighter as it nears metal and a buzzer that makes sound. In air tests I got 3 1/2 inches on a dime. In the dirt I got about the same. You can also adjust the sensativity by placing it at the desired range from a coin and twisting a knob. I am impressed with this experiment. I am sure that a person with a clue can easily build a quality probe, but this kit was easy enough that I could manage it...very cool indeed.
