Base Metal: Aluminum: Aluminum Decorator Foils: Aluminum Plate: Aluminum Sheet: 14 Gauge (0.064") Just remember, the more you discriminate, the less depth you are going to have and one can easily miss a small nugget or coin. Even large objects are properly read on the meter with the precise audio tone given. As soon as the detector search coil encounters a metal object (say a coin) it surrounds it with a magnetic field which caused interference to the frequency and thus the tone produced by the detector will alter. Some models of Compass can even give you a clue on its meter if you have found anything less than gold. Gold bearing material is collected from the mine bedrock area and run through a screening process to remove the large rocks and it is then made available to you. Get ready for the hunt of the season. You may need to use several over a period of time to find your best metal detectors but don't give up.
