Product Operation Guide
For better understanding of the responses for detecting different kinds of metal from the detector, it’s recommended to test before first use.
Indoor
- To test the detector, please place the detector on a wooden or a plastic table, and let the bottom of the search coil face the ceiling. Take off anything containing metal like a watch or a ring you are wearing.
- Slowly scan a sample you want the detector to find (such as a coin) 2-3 inches or more above the surface of the search coil. If any metal is detected, there would come audible signals, and the corresponding area would flicker.
Outdoor
- To test the detector, please find a place outside where there is no metal, and place a sample (like a coin) on the ground.
- Keep the search coil parallel with the ground and scan slowly. Please do not swing the detector like a pendulum while scanning.
