VLF Metal Detector

VLF Metal Detector

Metal detectors helped prospectors to discover precious artifacts and coins that were once the everyday items of use by our ancestors. Until recently, this privilege was reserved for the lucky few who could afford the expensive instrument. But with the advances in electronics and technology the price of these machines dropped to an affordable level.

Today, inexpensive, high quality consumer-oriented metal detectors provide millions of hobbyists around the world with an opportunity to discover hidden treasures, providing relaxation, excitement, the thrill of discovery and why not – profit.

As you start your search for the perfect metal detector, you will quickly discover that there are a multitude of detectors from which to choose from. There are machines using different technologies such as BFO (Beat Frequency Oscillator), Off-Resonance, IB (Induction Balance), VLF (Very Low Frequency), VLF/TR, TR (Transmit-Receive), PI (Pulse Induction), or RF (Radio-Frequency or Two-box detectors). Innovations in the field of metal detecting are a still going on — there are new patents and original designs born every day.

Today we will cover VLF  (Very Low Frequency) ,

This type of metal detector uses two coils, one sends and the other receives, to pick up on targets in the ground. The sender coil creates a magnetic field that reacts to metal objects. When a target is found, a current is formed, the receiver coil takes the signal and amplifies it to be heard through a speaker or headphones. Many detectors can even translate the signal into a number based on how strong the magnetic current is.

Because of its ability to give information back on targets, there are lots of metal detectors that use VLF technology. The control box is where the magic happens with this type of detector. It interprets the signal and turns it into easy to understand visual and audio cues. Depending on how much work goes into the interface and controls, you can ignore targets you don’t want to dig, see about how deep a target is, change the sensitivity, and much more.

Why VLF Metal Detector is Most Popular?

The popularity of VLF detectors is due to their ability to be used in many different areas and conditions. Most are all-purpose units that can be used for coin shooting in local parks, hunting relics on forgotten battlefields, or combing the beach for lost jewelry. Many also have submersible coils for shallow water hunting along rivers and beaches.

Versatility is what makes VLF the most popular detector type on the market.

Now that we’ve got our quick breakdown out of the way, how about we get to some actual recommendations? Here are just a few VLF detectors that we believe stand out from the rest of the pack.

VLF Metal Detectors Main Advantages

• Price – much cheaper than PI Machines
• Weight – Much lighter than PI machines.
• Less Power Required
• Small Nugget Detection, Usually better in VLF machines, particularly with small coils. This is totally lost in magnetite or hot rock areas because of noise and overload of the VLF circuits.
• Can get a multipurpose machine for gold, coin and relic hunting
• Metal Discrimination mode, to deal with iron trash.
• Not as sensitive to electrical interference.
