If you've been bitten by the treasure hunting bug, then you know that a metal detector or two is a necessity. It's important that you pick the best metal detectors for the type of detecting that you want to do. Some detectors will find treasure deep in the ground while others work better with stuff that is closer to the surface. Some work underwater, some are better on sand and some are better on dirt. Whatever your treasure hunting pleasure is, you want to be sure to arm yourself with the best detector you can.
Metal detectors have come a long way since the 1880's, growing in popularity and necessity in a range of industry's and uses from home to business. The secret to metal detection lies in the electromagnetic induction used by the device. It is really not a complicated piece of equipment with thousands parts and pieces. It consists of a mere four primary parts in the form of a control box containing all the device mechanics including controls, circuits and batteries, detection coil normally easily visible at the bottom of the device which is the actual metal detector, a shaft which links detection coil and control box and an optional accessory stabilizer for stabilizing the device during movement.
A.G. Bell was the first inventor of the metal detector for the purpose of detecting a bullet lodged in President Garfields' body. Although a very good idea and the start of a great invention, the first patent failed miserably, unable to detect the bullet. Another inventor called Gerhard Fischar came along in the 1920's who with great success re-invented Bell's patent. From then on, it was only a matter of time before the best metal detectors were used for recreational as well as commercial purposes.
Almost anyone can take up metal detecting as a hobby because most detectors, while a bit heavy, are quite easy to operate. There is no need to be a rocket scientist to operate a metal detector. Switch the device on at the designated power switch and off you go. Select an area you want to search and slowly sweep the detector over the area. An oscillator inside the control box will generate a current which will run through the search coil. The coil in turn generates a magnetic field, detecting any metal in the area. A clearly audible sound will be produced by the detector indicating metal detection.
Metal detector technology has come a long way since Bell and Fischar with the latest and greatest technology employed for metal detector design these days including very low frequency, Pulse induction and beat-frequency oscillation technologies. Today's detectors can find a small coin buried deep in the ground and, if you configure them properly will disregard all the trash allowing you to hone in on the treasure.
Metal detector have grown so much in popularity and technology that device uses are endless, from the well known beach combing and treasure hunting to metal leak detection at large beverage, food and chemical manufacturing plants.
