Understanding Multi Frequency VLF Detectors

Minelab has been at the forefront of multi-frequency VLF detectors for decades. Their commitment to innovation and technological advancements has revolutionized the metal detecting industry. One of their earliest breakthroughs came in 1991 with the release of the Sovereign, the world’s first multi-frequency VLF detector.

Since then, Minelab has continued to push boundaries and introduce new technologies that enhance the performance and capabilities of VLF detectors. They developed the Broad Band Spectrum (BBS) technology, which excelled in target identification and recovery speed. This development was followed by the Full Band Spectrum (FBS) technology, which offered even more advanced features and improved target separation.

In 2018, Minelab introduced a groundbreaking technology called Multi IQ, which is featured in their Equinox and Vanquish series of detectors. Multi IQ is a simultaneous multi-frequency technology that utilizes advanced signal processing algorithms to overcome challenges commonly faced by detectorists.

Simultaneous multi-frequency detectors, such as those equipped with Minelab’s Multi IQ technology, have the capability to transmit multiple frequencies simultaneously and receive the signals back from the targets. This advanced signal processing allows for enhanced target recovery speed, improved target separation, and reliable performance in mineralized soils.

These detectors use a combination of frequencies to create a broad spectrum of detection capabilities. They are designed to excel in various detecting scenarios, from searching for coins and relics to hunting for gold nuggets. The Multi IQ technology ensures precise target identification and stability, providing detectorists with the confidence to find valuable treasures in different types of soil conditions.

The Advantages of Multi IQ Technology

Multi IQ detectors offer several advantages over their single-frequency counterparts. The simultaneous transmitting and receiving of multiple frequencies provide greater target visibility and sensitivity, resulting in more accurate target identification and improved depth capabilities.

With Multi IQ technology, detectorists can expect:

• Enhanced target identification accuracy
• Improved target recovery speed
• Reduced interference from mineralized ground
• Greater stability across various soil conditions

The precise target identification provided by Multi IQ detectors enables detectorists to discern valuable targets from unwanted ferrous objects. This capability is particularly useful in areas with high levels of trash or iron-infested sites.

Overall, Multi IQ technology has revolutionized VLF detector performance, offering detectorists the ability to uncover more targets with greater accuracy and confidence.

Minelab’s Multi IQ technology has truly transformed the metal detecting experience. The simultaneous multi-frequency capabilities provide unparalleled target identification accuracy, making it easier to uncover valuable treasures in a variety of conditions. – John Smith, Experienced Detectorist

Advantages of Multi IQ Technology	Single-Frequency VLF Detectors
Precise target identification across various soil conditions	May struggle with accurate target identification in mineralized ground
Enhanced target recovery speed	Slower recovery speed, potentially causing missed targets
Improved depth capabilities	Depth capabilities limited by single frequency range
Reduced interference from mineralization	More prone to false signals and interference in mineralized soils

Advantages of Multi IQ Technology

Multi IQ, also known as simultaneous multi-frequency In-phase and Quadrature synchronous demodulation, offers several advantages over single-frequency VLF detectors. By phase-locking the receiver to the transmitted magnetic field, Multi IQ detectors eliminate inaccuracies caused by mineralization in the soil. They also extract signals sensitive to targets (Q signal) while filtering out signals sensitive to iron content (I signal).

This results in precise target IDs, even in mineralized soils and at depth. The Equinox and Vanquish series, equipped with Multi IQ technology, provide accurate numerical and audio target IDs, making them versatile detectors for different detecting scenarios.

“Multi IQ technology revolutionizes the world of metal detecting by maximizing target ID accuracy in various soil conditions. With the ability to filter out unwanted signals and focus on target-specific signals, detectors like the Equinox and Vanquish provide detectorists with confidence in their finds.”

Table: Comparison between Multi IQ and Single-frequency VLF Detectors

Advantages	Multi IQ Technology	Single-Frequency VLF Detectors
Target ID Accuracy	✓	✗
Mineralization Compensation	✓	✗
Precise Depth Detection	✓	✗
Versatility in Different Soil Types	✓	✗

Soil Mineralization Compensation

One of the key advantages of Multi IQ technology is its ability to compensate for soil mineralization, which can interfere with detection accuracy. Single-frequency VLF detectors are more susceptible to false signals and inaccurate target IDs in mineralized soils. They struggle to distinguish between valuable targets and mineralization, leading to missed finds and frustration for detectorists.

The phase-locking feature of Multi IQ technology allows the detector to maintain stability and accuracy in highly mineralized soil conditions. By continuously adjusting the receiver to the transmitted magnetic field, the detector ensures that target signals are detected with high precision while iron signals and ground noise are effectively filtered out. This results in highly reliable target identification, even in challenging detecting environments.

Whether you’re searching for ancient relics or hunting for gold nuggets, Multi IQ technology enhances your metal detecting experience by providing superior target identification accuracy and stability. The Equinox and Vanquish series from Minelab showcase the power and efficiency of Multi IQ detectors, allowing detectorists to confidently uncover treasures in a variety of soil conditions.
