There are metal detectors that are specifically designed to sweep search for gold. Gold metal detectors work on the principle of cancelling out mineralization, so whenever you find a metal detector specifically for gold, look for the ground balance. The ground balance feature in the metal detector cancels out detecting minerals in the soil and focuses on finding the metallic objects beneath that are unnatural to the soil.
As far as gold metal detectors go (although they might not be exclusive) they work on two principles; VLF and PI. VLF or Very Low Frequency metal detectors work in low frequencies unlike conventional metal detectors have a wider range of frequency to an extent that these VLF detectors can find a comparatively small nugget of a gold as compared to the other metal detectors. If you are searching for gold metal detector. There are two coil types; Concentric and wide scan. Concentric coils are preferred for differentiating between metals and minerals while widescan coils cannot do that.
do check for the size of the searching coil, as smaller search coils are less sensitive to small pieces of gold as compared to the metal detectors that have large searching coils. Pulse induction metal detector are newer technology that work by sending short pulses of one type of polarity. When the search coil is encountered with a metal object (of an opposite polarity) the pulse indication detector sets off sensing the opposite polarity, sends the signal to the receiver circuit.
Gold metal detectors can detect gold as small as the size of the grain and as big as an average nugget. The principle is that the gold as small as the size of grain is easier to find in the shallow depth (of 1 or 2 inches maybe) whereas, gold portions of the size of nugget can be search scanned at the depths of 1 to 2 feet.
Some metal detectors have the ability to find common trash items such as iron and stainless steel. Pulse detectors cannot filter out trash items.
Some of the popular choices for gold metal detectors include; Garrett GI 2500 metal detector, Marko Geotech, DRS electronics proradar X5 system, XP DEUS goldfield program etc. You can also look online for comparisons and reviews of several metal detectors that are projected to be good gold finders.

Metal detectors work on the principle of electromagnetism. Every metal (in solid state) has its own electric and magnetic field. Metal detectors have 2 circuits; one circuit, which is connected to a small battery which powers it up. This circuit is called as transmitter circuit. It sends electricity down the shaft to the coil at the bottom. The coil gets magnetized (changes its magnetic field) when this magnetized coil is swept on the ground and if there is a metal object near its sweep area, the magnetic field of the coil charges the metal object. The magnetic field of the metal detector changes the magnetic and hence the electric field of the metal object. This change in electromagnetism of the metal object is picked up by the receiver circuit of the metal detector. Due to the change in the magnetism of the coil of the metal detector, the electricity flows up the shaft of the detector to the receiver circuit. This change in the electromagnetism registered on receiver circuit confirms a metal detected by the coil.
Gold is not something that you can find in your backyard. And it is highly unlikely and improbable that you will stumble upon a pot of gold. Gold as metal can be found in the size of grain or even as big as nuggets. The place to find gold are the places where gold has been searched earlier and excavated from earlier. Placer deposits along the river streams and river beds can accumulate gold in small amounts.
You need to consider those states in the USA that used to produce gold in the earlier years. You cannot expect to find gold where it isn’t to be found so, research your search area. You can head out to the regional libraries or look for details on mines and geological surveys that shed light on details about the type of land and what metal it is abundant of. Also, you need to consider the federal laws of the area you are searching for and the stakes that it will have on the gold you excavate. If the land has a certain ownership and patent, there is a good probability that you might have ‘struck gold’.
