Metal detecting technology is becoming more popular because of the new type of metal detector, called PIs. They are becoming more popular among manufacturers, which means they are becoming more popular among consumers. They are becoming more popular because they are affordable.

The metal detectors in this lineup are better than those that use VLF or multi-frequency technology.

They are very powerful and come with a high price tag. But don’t worry if your budget doesn’t stretch that far. You can find less expensive ones.

This lineup provides a variety of top pulse induction metal detectors that are affordable for those who need them.

Reviews of the Top Pulse Induction Metal Detectors

1. Minelab GPX 5000

If all you see and dream about is gold, you need a pulse induction metal detector. Oh, and deep pockets, too.

The GPX 5000 is a machine for finding gold. It is not cheap, but it has some of the best technology for finding gold. The Multi-Period Sensing (MPS) feature lets you go deeper into the ground to find smaller pieces of gold.

Dual Voltage Technology (DVT) is a way to make sure you can see everything by using two voltage levels at different times.

SETA is a smart way to time your pulses. It ensures maximum depth and sensitivity regardless of interference from electromagnetic interference or the earth’s magnetic field.

When looking for objects with a metal detector, you can use different timings to find what works for you. Rx Gain has 20 levels of adjustment, so you can increase the detector’s sensitivity without it being too noisy.

The GPX has many features. These features include essential accessories, high performance, and a heavyweight of 7 lbs. If you have a chest harness, you’re ready to go!

2. Garrett ATX Extreme

The ATX Extreme is a metal detector with pulse induction that is easier to grasp immediately. It offers comparable capabilities to advanced VLF models, including Ground Track, Iron Check, and Frequency Scan.

Even if PIs are resistant to mineralization, it does not hurt to maintain ground balancing stability if it is ever required. The ATX’s Iron Check, Iron Audio, and customizable threshold capabilities may prove fair and useful for discrimination when connecting a DD coil. You can also gently alter the frequency to prevent EMI interference.

It’s easy to see why the ATX is a winner, as it is incredibly adaptable for a PI. Additionally, both saltwater and freshwater hunting is permitted. It is waterproof up to 10 feet.

Similar to most other PIs, it weighs nearly 7 pounds. This is a characteristic of PIs; therefore, begin shoulder exercises or acquire a harness.

What to Look for in a Metal Detector with Pulse Induction

This is a new metal detector technology. You might not know a lot about it yet. So, before spending a lot of money on something you don’t know much about, learn more first.

What is a Pulse Induction Metal Detector?

Pulse induction metal detectors are a different type of metal detector technology. They work differently than other metal detectors and are not affected by mineralization.

PI detectors work the same way no matter what the environment is. It doesn’t matter if you use it on sand, dirt, rocks, water, or even air.

How do Pulse Induction Metal Detectors Work?

A PI uses a single coil that simultaneously performs two functions. It can transmit and receive signals. Several PIs utilize numerous coils in tandem.

The coil transmits current in short pulses that last only milliseconds. As the transmitted current ends, it reverses in polarity and collapses. This process repeats again with approximately 100 pulses per second. However, this can vary between different models of coils and manufacturers.

This pulse technology protects a PI from highly conductive minerals in the ground. Metal is the only thing it’s looking for. This will make it easier for us to locate the metal.

A sampling circuit detects how long the reverse polarity and collapse process (reflected pulse) takes when metal is identified. There is likely metal present if it takes longer than usual, even for a few microseconds.

Where to use Pulse Induction?

PI metal detectors are really good at finding things in soils with many minerals. This is because they are not affected by the minerals like VLF detectors are. This makes them perfect for looking for things in areas where VLF detectors don’t work well.

  • Magnetite hot rocks (high iron content)
  • Saltwater
  • Dry and wet black sand
  • Coral

Some other areas that could be a problem for some unknown reason might be a good excuse to try out a PI. It might be worth it to borrow one and see if it makes a difference. You could then determine if it is worth the investment.

Discrimination & Pulse Induction

Discrimination is a weakness of the PI. They don’t like the way they’re detecting things, but they can’t do it accurately. This is because the detector can’t tell the difference between the length of reflected pulses from different types of metal.

Some PI detectors have adjustable discrimination, but they may not be useful because of their design. The short of it is that the PI is a dig-it-all metal detector.

Types of Metal Detecting with Pulse Induction

Because of their significant depth detection and immunity to minerals, PI’s are highly sought after for:

  • Gold prospecting
  • Beach hunting

Multi-frequency metal detectors are good for finding things on the beach, but there are some exceptions. If there is a lot of trash on the beach, you might be better off with a metal detector that can tell the difference between different metals.

Pulse Induction Metal Detector Accessories

Metal detecting requires specific supplies. This consists of headphones, digging instruments, sand scoops, and gold panning sets.

However, the weight of a PI may be difficult to manage with only a grip and an adjustable arm strap. Consider getting a chest or shoulder harness to aid in metal detector balancing.

A carry bag will help transport the detector and keep the disassembled parts together.

Don’t Forget the Usuals

You should still think about other specs and features when using a metal detector. This can help improve your performance with the metal detector.

  • Price
  • Searchcoil size
  • Waterproofness
  • Submersible
  • Threshold
  • Continuous ground balance

Final Thoughts

PIs (professionally installed) aren’t for beginners or amateurs. These machines are bought after mastering what you can out of a VLF.

Elect pulse induction may benefit you if you wish to increase your abilities or reach your objectives.

The only thing left to figure out is how much money you want to spend. To get the best performance possible, you will need more money.

Frequently Asked Questions About Pulse Induction Metal Detectors

What Is a Pulse Induction Metal Detector?

Pulsation induction Metal detectors are a more sophisticated method of locating metal. It transmits electric pulses into the ground to generate an electromagnetic field. This makes it easier to locate metals in regions with abundant mineralization.

What Is the Difference Between a Pulse Induction and VLF?

VLF transmitter and receiver coils measure how much the frequency changes when sent and returned. People use pulse induction metal detectors to find things by sending short pulses of electricity through a coil and seeing how long it takes for the pulse to come back.

How Deep Can a Pulse Induction Metal Detector Work?

Most metal detectors can find things that are 4-8ʺ near (10 – 20 cm) deep. In ideal conditions, a mid-range metal detector can find things that are 12-18ʺ (30-45 cm) deep. Some specialized detectors can go as deep as 65′ (20 m).

How Does a Basic Pulse Electromagnetic Induction Metal Detector Work?

Metal detectors broadcast an electromagnetic field into the ground to function. Any metallic targets within the electromagnetic field will become electrified and emit their own electromagnetic field.

Why Would Buy an Early Metal Detector Have Been Disappointing?

The main reason why buying an early metal detector would have been disappointing is because these detectors did not work very well. The first detectors were meant only to help miners. However, metal detectors are lighter, more efficient, and cheaper nowadays.

Is Minelab Equinox 800 VLF?

The Equinox 800 can detect small and large targets using five frequencies (5Khz, 10Khz, 15Khz, 20Khz, and 40Khz). This makes it possible to find both ferrous and non-ferrous targets.

Are There Different Kinds of Metal Detectors?

There are three metal detectors: VLF, PI, and specialty. They are categorized by how they work and what they detect.

What Is the Best Frequency for a Metal Detector?

Most general-purpose metal detectors are tuned to frequencies of 5 kHz to 15 kHz. This range is easy for beginners to manage and where most detectors are specialized. However, if you want to get more specialized detectors, you can always do that after mastering the basics.

What Is a Ferrous Target?

Ferrous objects are attracted to magnets. This means that they have iron in them, and the magnet will pull them close. Horseshoes, nails, and tin cans are all examples of ferrous objects.

Do Magnets Affect Metal Detectors?

Magnets with a metal coating, like iron or an alloy of iron and neodymium, have high conductivity and will be easily detected. Magnets with a ceramic coating, like ferrite, have low conductivity and won’t appear on the detector.
