Treasure hunting is as old as civilization itself. In the ancient days, pirates raided ships as explorers ventured into the far off islands in search of treasure. While much time has passed, the passion for treasure hunting has remained with us and the earth still contains many rear gems that can be discovered through metal detecting, ranging from old coins to gold nuggets, bullets and other stuff. Whether you are planning to go treasure hunting as a hobby, or as a serious activity to unearth massive treasures using some state of the art equipment, a metal detector will be indispensable in your ventures.
Metal detectors were invented in the early 19th century by Alexander Graham Bell and evolved over the years to incorporate more powerful functionalities, features and accessories for a seamless performance. Today, there are a lot of brands in the market producing a broad range of metal detectors, from simple budget-friendly devices for amateurs to professional-level metal detectors used by some of the world’s leading diggers. Some of the leading brands include Bounty Hunter, Garrett Ace, Fisher, Teknetics, Treasure Products and Lesche, amongst others.
All metal detectors work via a principle of electromagnetism and include search coils that emit electromagnetic radiation during the prospecting. When this radiation field encounters a metallic object in its reach, it energizes the electromagnetic field of the metallic substance which sends back an electromagnetic wave to the detector search coil. Since every metal has a unique radiation frequency and wavelength, this radiation can then be processed to produce a target response signal. Additional technologies are usually incorporated by various manufacturers to improve the efficiency of these detectors and make them as accurate as possible.
Before venturing into productive metal detecting, it is important to carry a decent amount of research to learn about various promising sites, and also the laws governing this activity. The historical societies or libraries can be great sources of information on the metal detectors. You can also check out the newspaper archives and your local town plans which contain some useful information on the various promising locations for relic hunting. Other popular grounds that you can check out include the beaches, picnic grounds, camping grounds, old houses, old public buildings, river banks, ancient town sites and woodlands, amongst others.
Important considerations about metal detection
When you are planning to carry out some search, there is a bunch of factors which you need to consider, such as the device’s depth of reach, which determines how deep you can go in your metal prospecting. You should also consider the target sizes and shapes, the degree of ground mineralization and the actual target material which you are searching for, such as gold, silver, brass, or bronze. These considerations will help you choose the best metal detector for the job.
