Air Metal Detectors

Air Metal Detector is cheap but professional metal detector that uses phone as a part of device.

Metal detector (ground search) allows you to find various valuable metal items, such as: coins, jewelry, gold, electronics, wall wirings, etc. It can be useful in different areas: treasure hunting, archaeology, security. Detector is able to differentiate the metal type, so you can discriminate not useful items. All known metal detectors incorporate big and expensive control block. Air Metal Detector utilizes user’s phone (Android or iOS) with application on it instead of control block. That allows us to make our device cheaper and more compact, while keeping all features of professional metal detectors (visible range, functions, etc.). Also, phone app gives us opportunity to create more clear and user-friendly interface. Such a design became possible here and now due to computational power and connectivity capabilities (Bluetooth) of modern smartphones. This way we can carve out new niche: affordable professional metal detectors. At this point we already have a working prototype: the coil (with all electronics inside) and phone app. The cost of prototype turned out to be one order less than the cost of existing similar devices. By testing the prototype in the field we can argue that its quality is as good as of existing professional metal detectors: the depth of detection, the speed of response, metal discrimination.
