What are Low-frequency metal detectors?

Welcome treasure hunters, When out on a metal detecting adventure, you often come across the choice of which type of metal detector to use, low-frequency or high-frequency, and what are low-frequency metal detectors?

Well, if you’re not sure about which type of metal detector might suit your needs, then there’s no need to worry, for in today’s guide we will explain both of these types.

High-frequency detectors are great for finding small things near the surface, but low-frequency detectors also have their own special strengths and are better for certain situations.

Imagine yourself in an open area, excited about the hidden treasures you might find. One important thing to think about is which type of detector to use for your adventure.

Low-frequency metal detectors, which work between 3 kHz and 8 kHz, have special features that many people like.

Knowing what they’re good at and when to use them is key to having a great time and finding cool stuff

“I suggest doing in-depth research on metal detector frequency, as it plays a very crucial role in metal detecting.”

Details About Low-Frequency Metal Detectors

Advantages of Low-Frequency Metal Detectors

Low-frequency metal detectors possess several distinct advantages that make them suitable for various metal-detecting scenarios:

1. Deeper Target Detection: Low-frequency detectors excel at detecting larger, deeper targets due to their longer wavelength, which penetrates deeper into the ground. 

This makes them ideal for seeking relics, buried caches, or large metal objects hidden at greater depths.

2. Effectiveness in Mineralized Soils: Low-frequency detectors are less affected by ground mineralization, making them more effective in highly conductive soils where high-frequency detectors may struggle. 

This adaptability allows them to perform well in diverse soil conditions.

3. Ideal for Large Targets: Low-frequency detectors are particularly well-suited for detecting large targets, such as relics or buried caches, due to their deeper penetration and sensitivity to larger metal objects. 

This makes them a valuable tool for uncovering hidden treasures from the past.

4. Cost-Effectiveness: Low-frequency detectors are generally more affordable than high-frequency detectors, making them a budget-friendly option for beginners or those prioritizing deeper target detection. 

This cost-effectiveness allows more individuals to enjoy the thrill of metal detecting without breaking the bank.

Limitations of Low-Frequency Metal Detectors

While low-frequency detectors offer distinct advantages, it’s important to consider their limitations:

1. Sensitivity to Small Targets: Low-frequency detectors are less sensitive to small targets, such as coins or jewelry, making them less suitable for areas where these types of targets are prevalent.

This focus on larger, deeper targets may not align with the goals of treasure hunters seeking smaller, more delicate objects.

2. Shallower Target Detection: Low-frequency detectors are less effective at detecting shallow targets, as their longer wavelength is less sensitive to smaller metal objects near the surface. 

This may limit their effectiveness in areas where shallow targets are more common.

3. Ground Balance Sensitivity: Low-frequency detectors are more sensitive to ground interference, requiring careful ground balance adjustments to ensure optimal performance. 

This can add a layer of complexity to the operation and may require more attention to ground conditions.

4. Target Identification Challenges: Low-frequency detectors may face challenges in accurately identifying the type of metal present, especially in highly mineralized soils or when dealing with a variety of target types. 

This may require additional research or experience to correctly identify unearthed objects.


Low-frequency metal detectors offer a valuable option for treasure hunters seeking to uncover larger, deeper targets in various soil conditions.

By carefully considering their advantages and limitations, you can make an informed decision and optimize your treasure-hunting expeditions based on your target types, soil conditions, and experience level.

We hope that now you are informed enough that you can make a decision on which type of metal detector will suit your needs.
