Long Range Gold Detector Underground Metal Scanner with High Definition Screen for Gold Silver Copper Item Type: Long Range Gold Detector Material: ABS Maximum Detection Depth: Approx.30m / 98.4ft (This instrument can detect at least 6m / 19.7ft for a 5 x 5cm / 1.97 x 1.97in object. For a 30 x 30cm / 11.81 x 11.81in object, it can detect 5 to 12m / 16.4 x 39.4ft, and if an object of this size is buried for a long time, it can reach Approx.30m / 98.4ft. If the area of the object is larger, its detection depth will be deepened.) Specific functions: Metal detector can accurately determine the buried location of the object and can be located. Metal detector can also rely on frequency regulators to identify specific types of metals.
