Peter Vizmuller or others:
Thanks for the great info on the magnetometers. I was interested in
building my own or buying one. I'm not looking to spend a whole lot and I'm
not quite sure how much these instruments are going for.
What I am interested in, is looking for a magnetometer to look for "buried
treasure" or mineral prospecting. If you or anybody knows of any convenient
or affordable magnetometers that I can experiment on please let me know.
Thanks everybody at ProtonMag for their input.
P.S. The attachment sent by Peter Vizmuller: What program do I open up
this document with?
Thanks again,
Tim Duguid
