The size, shape and orientation of the metal particle also is important. Since size, shape and orientation of metal contaminants is not possible to control, it is best to operate a metal detector at the highest possible sensitivity setting. Providing treasure hunting supplies to the beginner as well as the seasoned professional. Manufacturers of metal detectors are constantly tuning the process to make their products more accurate, more sensitive and more versatile. On the next page, you will find links to the manufacturers, as well as clubs and more information on metal detecting as a hobby. The most basic way to detect metal uses a technology called beat-frequency oscillator .
The AT Pro balances user-friendliness with more advanced features, while also being able to handle almost every type of terrain you might search. Metal detectors work by producing specific noises whenever you scan an area with metallic items in it. There are additional settings that can help you fine-tune the signal to locate specifically the kinds of items you’re looking for. But if you’re just starting out, it can be hard to find the correct balance. A handful of preset modes on your metal detector (such as “jewelry”, “coins”, etc.) can help you strike gold — literally or metaphorically — much quicker.
Of course, you can expect to find valuables left behind by beachgoers on the sand, but don’t forget that there will be things in the water too. If you plan on using your detector underwater, the coil needs to be waterproof. We made sure that all of the models we tested were advertised as having waterproof coils.

The metal detecting community and professional archaeologists have different ideas related to the recovery and preservation of historic finds and locations. Archaeologists claim that detector hobbyists take an artifact-centric approach, removing these from their context resulting in a permanent loss of historical information. Archaeological looting of places like Slack Farm in 1987 and Petersburg National Battlefield serve as evidence against allowing unsupervised metal detecting in historic locations. Hobbyists often use their own metal detecting lingo when discussing the hobby with others. This 156-troy-ounce (4.9 kg) gold nugget, known as the Mojave Nugget, was found by an individual prospector in the Southern California Desert using a metal detector. People can use metal detectors in public places (parks, beaches, etc.) and on private property with the permission of the owner of the site.
Thick padding and Velcro-strapped forearm rest make this the comfiest metal detector. The displays of metal detectors come in a wide array of options, some better than others. In general, an LCD display is preferable over the old knobs and meter layout, as it gives much more information along with more options for customization. We found that when the different components on a detector snapped together, this provided a sturdier frame than those that were screwed together. Also, the component of the metal detector that rests on your forearm should be large and comfortable, as we found that much of the weight of the detector rests on this spot.
