Can I use a metal detector to detect aluminum coil?

Yes, you can use a metal detector to detect aluminum coils. Metal detectors are designed to detect various types of metal, including aluminum. While they are often used for detecting ferrous metals like iron, they can also pick up non-ferrous metals such as aluminum. The effectiveness of detecting aluminum may vary depending on the type of metal detector and its sensitivity settings. Ground conditions and the size and composition of the aluminum coil can also affect detection. It's important to adjust the metal detector to the appropriate settings for detecting non-ferrous metals to increase the chances of successful detection.
