ToggleUnderstanding the Basics of Metal Detection.

At its core, a metal detector is a device that uses electromagnetic fields to detect metal objects buried in the ground or hidden beneath other materials. It consists of three main components:
- The Coil
This is the part that you sweep over the ground or target area. It generates an electromagnetic field.
- The Control Box
This houses the circuitry and controls, including the LCD display and settings for both sensitivity and discrimination.
- The Shaft
This connects the coil to the control box and provides stability while using the metal detector.
The Science Behind Metal Detection.
Metal detectors operate on the principle that different metals have varying levels of conductivity.
When the coil emits an electromagnetic field, it induces a current in any nearby metal objects. The detector measures this induced current, and based on the metal’s conductivity, it can distinguish between different types of metals, such as gold, silver, or iron.
