Metal Detector is a user-friendly app designed for both beginners and experienced treasure hunters to locate metallic objects hidden underground, behind walls, and more. Featuring a sleek, minimalist interface, the app utilizes advanced magnetic sensing technology to detect metals such as steel and iron. It offers vibrational alerts through haptic feedback to ensure users never miss a find and includes a calibration feature for precise detection by simply shaking the device. For optimal performance, the app works best when the device's camera is near the target area. Key features include: Detection of metallic objects underground and behind walls Simple and intuitive design Vibrational alerts for immediate feedback Specialized in magnetic metals like steel and iron Easy calibration with a device shake Enhanced sensitivity when the camera is positioned near the search area This app measures magnetic field with an embedded magnetic sensor. The magnetic field level (EMF) in nature is about 49μT(micro tesla) or 490mG(milli gauss); 1μT = 10mG. When any metal(steel, iron) is near, magnetic field level will increase. Download Metal Detector today to embark on exciting treasure-hunting adventures and uncover valuable treasures and fascinating artifacts effortlessly. https://nasuf.com/metaldetector/privacy-policy.html https://nasuf.com/metaldetector/terms.html
