Buying A Metal Detector – The Guide For Girls……

The most challenging part of selecting and purchasing a metal detector for both a beginner and an experienced brand switcher is to choose a right one from dozens of new models that continuously appear on the market. If you’re considering on purchasing your first metal detector making the right choice of selecting the best one will depend on your goals, needs, abilities, and amount of money you’re willing to spend for the equipment.

Buying the right metal detector will depend on your understanding of the types of technologies, designs, features, modern search coils and applications used on it. Here are five basic technologies which have been integrated into the electrical design of metal detectors.

Transmitter/Receiver

The TR technology is based on induction balance and is one of the earliest technologies to be incorporated in the electrical design of metal detectors. The metal detectors of this technology can tell the difference between ferrous and non-ferrous objects and do not have enough depth in the high mineralized ground. These types of metal detectors are now obsolete.

Beat Frequency oscillation 

The BFO is an old technology and is also based on induction balance. The metal detectors made of it are cheap for they can go for less than $100 and have been designed as toy detectors for kids. With it being easier and cheap to make, it has shortcomings when compared with other technologies. For example, it cannot distinguish between the different types of metals. Finally, it is a technology that is still used in cheap handheld devices.

Very low frequency 

The VLF technology can distinguish between the different types of metals. The metal detectors made of it are the most common detectors. The 4 kHz range of these detectors can work best in the high mineral content ground and are sensitive to silver and copper but not gold. This is because gold prospecting metal detectors do always have a frequency that ranges from 18 kHz-71 kHz.

VLF/TR

This technology is a combination of very low frequency and transmission technologies. Thus metal detectors made of this type of technology can simultaneously control trash and ground mineralization.

Pulse induction 

The metal detectors made of this type of technology cannot discriminate between various types of metals. Thus they are difficult to use on inland sites with a high concentration of trash. These metal detectors can best be used on high mineralized soils or salty water where other technologies have trouble working. It is a technology that can detect a target much deeper compared to other technologies.

Other metal detecting technologies that include other categories or a combination include

• Broad Band spectrum BBS

• Full Band spectrum FBS

• Full Band spectrum 2 FBS2

• Off Resonance

• Radio frequency

The Broad Band and Full Band Spectrum technologies are used by Minelab metal detectors and have advantage over single and dual frequency metal detectors.

Conclusion 

One thing you should remember is that the best way to arm yourself with the right metal detector is to know your goals, abilities, and opportunities available in the area you reside.
