**SAFE HI-TEC 6, 12, 18 Zones Walk Through Archway Metal Detector Door SA-IIIA**
The SA-IIIA is a high-sensitivity digital walk-through metal detector that uses advanced electromagnetic testing and digital processing technology. It provides excellent detection for both ferrous and non-ferrous metals, as well as personal items such as coins, keys, and belt buckles. The highest sensitivity can detect a 20 mm diameter steel ball. With a multi-layered overlapping coil design and high-brightness LEDs, it accurately indicates the horizontal position of detected metal objects, making it easier for operators to identify potential threats.
**Function:**
This walkthrough metal detector is ideal for detecting dangerous items such as knives, guns, and other hidden metallic objects on individuals. It is widely used in security-sensitive areas like airports, schools, and government buildings.
