Metal detectors are the most common tool amongst amateur prospectors and treasure hunters. Gold detectors are metal detectors but are used purposely to hunt for gold. Understanding how these tools find gold makes it much easier for you to use a metal or gold detector.

Metal detectors work by transmitting an electromagnetic field into the ground, then tells the user the return signal. The electromagnetic field that gets transmitted by the metal detector induces loops of electrical current within certain materials. These currents then generate their own electromagnet fields which the metal detector receives and analyzes.

Gold detectors take this a bit further; they measure inductance and conductivity. This is the amounts of currents produced in the target. Conductivity is how easy those currents flow. By measuring the size of the current and how fast they are travelling gold detectors can work out the time constant of the target. Time constants can vary between different targets, small bits of aluminium foil have short time constants, but gold and rings have a longer time constant. Scraps and steel parts have even a longer time constant. Gold detectors can specifically search for targets that fall within that range.

Tips on choosing a metal or gold detector:

When choosing a metal detector, always take into consideration the climate and what the land composition in your area are, this is a very important factor to keep in mind. The three main categories that metal detectors fall under are for land-based coin and relic hunting. Beach and underwater meat detecting and prospecting for gold and all types of other metals. But land detecting is the most popular type of metal detecting.

Decide which type of targets and land compositions are found in your area, for example, if you live near a desert you will not need an underwater metal detector. The best metal detectors used for local hunting would be this for coin hunting, jewellery and gold prospecting. 

Learn and browse a little bit of metal detecting and learn the basics. This will help you with getting a better understanding of all the different types of models and their capabilities.

if you love history, going outdoors, discovering new locations and territories, engaging and networking with people to get permissions, finding old coins and relics and from time to time collecting valuable items like Gold. Then, Metal Detecting is totally worth it.
