Beat – frequency oscillation detectors The BFO is a basic example of metal detector technology, which is a perfect starting point for understanding how metal detectors operate. It’s the best way to understand how metal detectors operate. Two radio frequency oscillators are calibrated to the same frequency in a base frequency metal detector. One is…
To say that all metal detectors are created the same would be a lie. Each and every metal detector brand and model are completely different. They all serve the same purpose though, and for the most part they all have the same basic parts. Almost every single metal detector can easily be broken down into…
Metal detecting could be defined as the process of finding metal objects using an electronic device, but between you and me, I’m pretty sure that sounds pretty cold and anticlimactic. It fails to mention the beauty and the aesthetic parts of the hobby you will discover as you dig deeper. There are of course different…
By the end of the 19th century, due to the growing knowledge and theories that surrounded electricity, magnetism and how the two could be combined, many engineers and also scientists used said knowledge to try to create a machine capable of detecting and pinpointing metal, this led to the creation of the metal detector. Now,…
The metal detector is a device used to detect as the name indicates-metal or the occurrence/presence of metal around. They are particularly used to find metals hidden within objects or objects such as treasure, coins, etc. that may be found underground. Metal detectors are usually units that are handheld and have a sensor probe that…
