VLF - Very Low Frequency
As the name suggests, these types of detectors are the most commonly used ones. With the VLF detector several types of metals can be detected and it uses two rounds of wire. The coil of wire on the outside is the transmitter while that on the inside is the receiver. The transmitter emits a low-frequency magnetic field which is responsible for the transmission. The receiver receives the signal and interprets it according to the magnetic pulse. Since, this detector can be used to detect metals hence, it falls in the category of gold metal detectors.
Pulse induction detector
This type of metal detector uses a magnetic field to generate a pulse. Unlike the VLF detectors, it consists of only one coil. This is the most common type of detector which is used by the treasure hunters because of its ease of access. When a metal which is present underground reflects the signal, the pulse inductor switches the mode and listens for the source of the reflected sound and hence determines the position of the same.
Beat Frequency Oscillation
A metal detector which uses this technology is the simplest and the most inexpensive metal detector. They are mostly used by beginners because of their ease of access. Just like a VLF detector, this also uses two set of coils for the effective detection of the metals. An oscillator is used to create constant signal at a particular frequency and that is emitted by one set of coils. On the other hand, the second coil is responsible for interference of this frequency and causes a change in the tone of the audio.
Looking for the best metal detector for a beginner will likely be overwhelming for a new metal detectorist. There are numerous brands, models, and other options to pick from. Being familiar with what to search for will make this a simpler process.
Some of the things that are likely to affect your choice about what the best beginner metal detector are the cost, the features, and how you plan to utilize the detector. If you're planning to use the metal detector for gold prospecting or in water you may want one specialized for those needs. But for almost all beginners, a general-purpose detector likely will be what you want.
You need to come up with a budget. A top-grade metal detector may cost many thousands of dollars, 1while a beginner metal detector is able to be had for much less. Expect to commit to at least $100-$150 for a decent metal detector. Any metal detectors priced less than this will probably disappoint you in their performance. For $100-$150 you can get a detector which is plenty for many beginner detectorists' needs. They are going to simple, which often can be advantageous for a beginner, but will most likely lack many features of more expensive metal detectors.
Several of the most popular beginner detectors sell for about $200-$300. They have become well liked because around this price point you are able to attain some of the features that more professional metal detectors have, but at an inexpensive price. You will find detectors inside of this price range with features such as depth indicators, target ld.’s, and pinpointing. As you continue to rise in price you can expect to attain more features with your detector-
