Consumer metal detectors pair a search coil, discrimination electronics, and—on serious units—waterproof coils for beaches and fields. They do not make you an expert, but they open a find channel with strict legal rules.
Before the waterproof detector CTA, grasp frequency, coil size, and tone ID—the triangle separating toys from tools that hit coins at ~15 cm.
How the coil works (no PhD)
The coil emits an EM field; buried metal distorts it. The machine maps that to tone and ID numbers by approximate conductivity.
Discrimination: friend and trap
Cranking discrimination skips pull-tabs… and sometimes small silver or low gold. Learn to lower disc on historic ground and dig thoughtfully.
