HOW TO MAKE A METAL DETECTOR
Excellent tutorial. However it did not function in minnesota --too much iron in the grnd. I used it on wood chips at local parks. Was only good to about 6 inches, if that. Smallest bump and youd have to retune the coil. Very educational, but not so practical.
Heading to mexico in a month and id love to take one down to roam the beach. Most of the vlf schematics look pretty advanced for me. Anyone know of a good PI design? From the looks of it, bfo detectors are obsolete.
I seek coins and jewellery only
Im still roaming the arduino forum, but theres not much on here.
Thank you
