Why would PI be silly?


I was thinking earlier today that having a small wand-coil to plug into my friend's Maxi-something would be a handy tool. The 2 by 4 foot coil leaves entirely too much space to wonder about, and the 4 by 4 foot only helps a little bit.

Re: Suggestions for a 'pinpointer' design

>What would be interesting would be a pinpointer that has far better depth that the currently available products - specifically the ability to pick up a dime at about 3 inches, with a zero motion, all metal operation. None of the universal pinpointers are capable of doing this.


Thought about this, too...


>I think that some type of BFO would be the best bet, and PI would be silly.


I think one of the commercial pinpointers is PI. Does anyone know for sure what the different makes are? An easy design might be a VCO-type detector.

That's a pretty steep price to pay for a "Pocket Compass"
