Overview
The AR944M Underground Metal Detector is a professional detection device under the brand SMART SENSOR that uses the principle of electromagnetic induction. It detects buried metal objects by emitting electromagnetic signals, which can help users determine the location, size and type of metal objects.
Features
1. Adopting the principle of electromagnetic induction, accurate and reliable detection
2. With black non-ferrous metal discrimination function
3. Provide LED light and sound dual detection prompts
4. Sensitivity adjustment function
5. Built-in searchlight for easy night operation
6. With low power prompt function
7. Support the use of external earphones
8. Powered by a 7.4V 2000mA lithium battery, the battery life is 6-10 hours
Principle
The AR944M underground metal detector works based on the principle of electromagnetic induction. The detection coil emits electromagnetic signals. When the signal encounters an underground metal object, it will generate eddy currents inside the metal, and the eddy currents will generate a new magnetic field, which in turn affects the original magnetic field. The detector detects this magnetic field change and sends a prompt signal to determine the existence of the metal object.
Applications
Archaeological research, treasure hunts and treasure hunting activities, metal detection and exploration, safety inspections and dangerous goods removal, pipeline and cable laying and maintenance
Steps
1. Turn on the power switch
2. Selectively equilibrate or identify detection patterns according to detection requirements
3. Adjust Sensitivity to Appropriate Level
4. The handheld detector moves slowly on the ground to scan
5. When the detector emits an LED light or sound prompt, mark the location
6. Use the supporting tools for excavation confirmation
Notice
Do not use in extreme temperature environments
• Avoid strong impact or falling the detector
• Make sure the battery is fully charged before use
• Keep the detector moving smoothly during detection
Be careful to distinguish between metal signals and geological disturbances
• Conduct detection operations in safe areas
• Regularly clean and maintain the detector
