How to operate a handheld metal detector:

1. Turn on the power switch and hear a "click" sound, indicating that the power is on and the green light is on. If the green light of the handheld metal detector does not light up, it means that the battery is not installed or the battery has poor contact. If it makes continuous sounds or vibrates continuously, it means that the battery can no longer be used and should be replaced with a new one.

2. Sound and vibration switching switch selection: press the red button switch, the handheld metal detector alarm mode is vibration. Release the red button switch and the alarm mode will be sound.

3. After turning on the power, you can perform high-sensitivity detection. Hold the handle and scan the detection surface around the object to be measured. When there is a metal object in the hand-held metal detector, it will emit an alarm sound or vibrate, and at the same time, the green light will turn into a red light; Stop scanning, the alarm sound or vibration will stop, and the red light will turn to green.

4. Handheld metal detector low sensitivity test: If you need to exclude small metal objects, you can press and hold the low sensitivity switch. Scan the area around the object to be measured. When there is a metal object, an alarm sound or vibration will be emitted, and at the same time, the green light will turn into a red light. Stop scanning, the sound or vibration will stop, and the red light will turn into a green light. Because the sensitivity is reduced by more than 5 times at this time. Therefore, what is measured at this time are generally relatively large metal objects.
