The 5″ DD coil for a gold metal detector is a large-diameter coil with a coiled wire at the end of it.
The coil is placed around the object that you want to find, and then it is moved along the ground while you are
holding down the button on your metal detector. When you press down on the button,
it activates your metal detector’s internal circuit and causes the current to flow through your coil. This allows you
to detect objects that are buried in the ground such as gold nuggets or jewelry pieces.
When using this type of device, it’s important not only to pay attention to where you are walking—
you should also try not to wave your hand around when you’re detecting for gold because this could cause damage to your device’s internal components.
