Stud Find - 金属 探测器

------Metal Detector------
Use your iPhone to find nails or any invisible magnetic metals on wooden structures inside walls.
Two conditions need to be met for the normal use of this app: 1. The nails inside the wall must be made of magnetic materials; 2. Your device (iPad, iPhone or iPod) needs to have a built-in magnetometer. This app cannot detect non-magnetic nails, such as aluminum nails or wooden nails.
Note: If your system has a built-in Compass App, then your device has a built-in magnetometer.
------Instructions for Use------
Please remove the device case before using this app.
If you need to calibrate the magnetometer of your device, you can hold the device and draw an "8" shape, and then click "Strength" in the center of the app interface to reset the reading.
If you are using a device of iPhone 5s or earlier models, you can sweep the right edge of the device closely along the wall across the detection area, which can help you locate more accurately; if you are using a device of iPhone 6 or later models, then use the upper edge of the device to closely sweep along the wall across the detection area.
