**6 Zones Walk Through Door Frame Metal Detector SA-IIIA for Events Entry**
The SA-IIIA is a high-sensitivity digital walk-through metal detector that utilizes advanced electromagnetic testing and digital processing technology. It offers excellent detection capabilities 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, it provides accurate horizontal positioning of metal objects using high-brightness LEDs, making it easier for operators to identify the source of detection.
**Function:**
This walkthrough metal detector is ideal for detecting dangerous items such as knives, guns, and other hidden metal objects on individuals. It's widely used in events, airports, and security checkpoints.
