Various Types of Metal Detectors
One unique hobby that you must heard of is the treasure hunting. It is also a bit expensive as one would have to possess a reliable sturdy metal detector to be able to have a successful gold hunting activity.
Thanks to the presence of thrift shops old yet slightly used metal detectors that come in affordable prices can now be easily had by just about anybody. No detector can be cheap but at least it won’t require anybody to break a bank and if it doesn’t work you can always return it to the shop owner.
He might just give you a great bargain for the next best detector that you will find. But wait you just might have to know yet that there are three kinds of metal detectors. Yes, there are truly three of them. These are the following: the Very Low Frequency (VLF) metal detector, the Pulse Induction (PI) detector, and the Beat Frequency Oscillation (BFO). Want to know if what you’re buying is a good one for you? Read on and you will soon find out which type works for the beginner and which one is good for the seasoned treasure hunter.
The BFO detector is meant for the beginners to aid them in their gold and silver hunts. It is also said to be the most inexpensive and the simplest.
This kind of metal detector makes use of two separate wire coils used for detection. It’s the first coil that gives off a signal constantly with a default sound while the second coil emits audio frequencies each detection of metallic objects.
Because of the simplicity of its operations, a BFO is unable to make accurate detection of metal-based items that are of value from those that are considered as trash.
Thus, if accuracy is what you need, then the PI detector is meant for you. These are the kinds of detector that are used in airports and by treasure-hunters searching for objects buried deep into the surface of the earth. The VLF works much like the BFO but it comes with a higher level of accuracy.
