I found toys at the beach and change at the park testing these expert-approved metal detectors
Scanning parks and beaches with one of these can be a unique and fascinating hobby.
Recent studies have shown metallic objects have their own magnetic fingerprints based on size, shape and physical composition. Scientists look to leverage these observations to potentially create a ...
If you think of a metal detector, you’re probably thinking of a fairly simple device with a big coil and a piercing whine coming from a tinny speaker. [mircemk] has built a more modern adaptation.
WASHINGTON, January 21, 2020 -- Most traditional electromagnetic methods for detecting hidden metal objects involve systems that are heavy, bulky and require lots of electricity. Recent studies have ...
