Vlf Metal Detector

Very low frequency vlf detectors are the most versatile metal detector types based on the range of metallic objects you can find with them.

Vlf metal detector. As all ib designs the vlf detector combines two balanced coils. This metal detector is capable of detecting small metal objects at great distances. The coil or search head of these detectors consists of two separate coils of wire. For example a small metal coin or gold ring can be found at a distance of up to 25 cm.

Very low frequency vlf very low frequency vlf is the technology built into most detectors pretty much any machine under 1 000. The outer coil produces a vlf below 30khz impulse which is directed into the ground. These are signal frequency machines used for coin jewelry and relic hunting. Since most metals vary in both inductance and resistance a vlf metal detector examines the amount of phase shift using a pair of electronic circuits called phase demodulators and compares it with the average for a particular type of metal.

So what does vlf mean. When the impulse comes into contact with a metal object below ground the impulse is reflected back. Works as described above with two coils one transmitting and one receiving. Vlf detectors usually operate at a frequency in the range of 3khz 30khz.

The outer coil acts as a transmitter using alternating current to create a magnetic field that is distorted by a. Vlf is today the most common metal detector and the one that works best as an all round detector. If you re just starting out get yourself a vlf. Diy sensitive vlf metal detector with smartphone detects a small metal coin at 25 cm and pot lid at 1m distance.

Lightweight and adjustable in size young and old alike will delight in hours of productive detecting. With its excellent sensitivity control this vlf metal detector can detect coin sized objects up to five inch deep and larger items up to three feet deep. Featuring a lightweight ergonomic design it is easy and comfortable to operate. When it comes to metal detectors in general there are mainly 2 different types vlf very low frequency and pi pulse induction detectors however unless you are a professional gold prospector all what you will need most of the time is a vlf detector.

The vlf metal detector will help you get started finding your treasure without spending a fortune to get it. The bounty hunter treasure tracker iv metal detector offers you high performance metal detection. Iron relics coins and household items as well as precious metals like silver and gold won t escape bounty hunter s vlf metal detector. Vlf technology is a good detector that meets most detector needs.

Phase shift provides vlf based metal detectors with a capability called discrimination. The most popular and most widely used detectors are vlf detectors.
