George Overton and Carl Moreland were two pioneers in the metal detecting industry who recognized the need for more advanced and reliable technology. Overton, an engineer by trade, began experimenting with metal detectors in the 1970s. He developed a new type of detector that used a balanced coil system, which significantly reduced interference and improved target accuracy. Moreland, a fellow innovator, joined forces with Overton to refine the design and create some of the most iconic metal detectors of the era.
Carl Moreland is another iconic figure in the world of metal detecting. With over 40 years of experience, Moreland is widely recognized as one of the most skilled and knowledgeable metal detectorists in the industry. His expertise spans a wide range of applications, from relic hunting to gold prospecting.
If you have ever wanted to understand how metal detectors work, you have likely come across the book by George Overton and Carl Moreland. It is widely considered the bible for hobbyists, engineers, and DIY electronics enthusiasts who want to design, build, or repair metal detection technology.
