Hammerhead PI with large coil

[Thomas]

Are there any experiences of the Hammerhead PI with a large coil, about 1 m square, in regard of sensivity to ferrous objects?

I'm looking for a combination of PI unit and coil to build myself, capable to perform equal or better than the Pulse Star Pro II PI detctor (wich is a very nice device).

Thanks!

Hi, the coil of one square meter, that means seven turns and the neutralization resistor about six hundret ohms. At least from my experience with a transmitter on the picture. Sid
