Even now when ancient pirates' treasure chests seem to be found only in the movies and books, people still do believe that treasures exist. There are still those who spend their time, exert effort, and spend their money only to locate and excavate hidden crates and chests filled with precious jewels and gold.

There are also those people who dive under water and stumble upon sunken ships and discover the treasures that these carried to the depths of the ocean. Both diving and surface treasure hunters truly require equipment to achieve their goals. Aside from the maps, they need metal detectors especially if the objects of their search are buried deeply in the ground.

Diving treasure hunters may be unfortunate enough not to find treasures on the seabed. After a period of time it is only natural for sunken ships to be buried in mud or muck. Of course, without the use of metal detectors, the divers can only be wasting the valuable oxygen in their tanks. Not only will their quest be unproductive; they also spend for their diving gear without profit from a treasure find. This is why it is necessary for them to equip themselves with a metal detector.

However, not all these detectors have the capacity to function underwater. In fact, majority of these are only meant for land use. If the ones meant for land detecting are used underwater, these battery-operated devices might short-circuit, making these permanently damaged and not anymore useful. Divers who like to look for treasures underwater and on the seafloor may need to use a special type of metal detector that is particularly designed for this use. You can find such types of detectors sold out there in the market. Aside from the detector itself, the divers can also avail of certain accessories that can make treasure hunting underwater more effective.

Detectors, that are either for land or underwater use, are effective only when the area of these treasures has been specified down to the least general. Thus, it is necessary for treasure hunters to primarily reduce the perimeter as much as possible. With the most specific site identified, the use of detectors will truly produce positive results.

It is also a necessity for one to be aware of one's level of expertise in using metal detectors if you are planning to have one for yourself. A more complicated detector is intended for the experts as the beginners must go for the detector suited for the novice.
