Is There a Difference Between Metal Detectors?

One question that the clients often ask us is that, Is there a difference between metal detectors? Because when researching metal detectors, different sellers claim the same functionality for different devices.

The seller of both devices claims the same performance and depth potential. However, the detectors vary in price, with one device priced at $400 and the other at $800.

We will address the curiosity of our clients by answering the question, Is there a difference between metal detectors?

In this article, we will discuss the elements and features that cause metal detectors to differ from one another. Additionally, we will explore the factors that determine the disparity in metal detectors.

Price versus Performance Comparison

There can be complications behind the price versus the performance of detectors. The performance depends on the availability of advanced functions and features.

Thus, the price increases with the presence of upgraded features. Advanced features result in higher prices, while basic features correspond to lower prices.

Before buying a metal detector, it’s crucial to research the different types of metal detectors available to avoid any potential issues.

Let’s Find Out Is There a Difference Between Metal Detectors?

Depth Range

One obvious reason for increased prices is the high-depth potential of the detector. If one device can go up to a depth of 1 foot and another device up to 4 feet, the price will vary greatly. Similarly, if another device has a depth range of 8–10 feet, the price range will increase accordingly.

That’s why VLF technology devices are relatively cheaper than PI devices. Because VLF provides less depth for detecting metal items.

In contrast, PI devices support larger coils, are more powerful, and offer a greater depth range. As a user, you will observe a substantial difference in prices.

The function of discrimination is an advanced-level feature and is not present in every metal detector.

Furthermore, some detectors have stronger discrimination capabilities than others. So, detectors with better discrimination cost more, while those with less or no discrimination are cheaper.

Some devices only have the option of iron discrimination. In such devices, only iron can be filtered out, and for other metals, the detector will register signals.

In upgraded detectors, discrimination can be efficiently done with a target ID filter, where the user can block specific IDs.

For example, if there are 0-99 target IDs, the user can block target IDs from 1-10 or 1-20, according to their needs. By doing this, the detector will not create alerts when encountering iron or iron-related items.

Notch Filter

A notch filter is a top-of-the-line feature that allows the user to block specific IDs without blocking the target IDs from 1. For example, if the user intends to block IDs from 40-50, they can easily do so through a notch filter.

In this way, there will be no effect on the target IDs from 1-40. As a result, an individual can reject bronze or specific metals that are readily available in an area.

So, depending on the functions you desire, you have to bear the cost accordingly.


Sensitivity is also a feature that adds to the price. Let’s take the example of gold nugget devices and coins and relics devices. Detectors with high-frequency functions are costlier because high-frequency devices are more powerful.

Therefore, gold-nugget devices will be more expensive. The price of gold nugget devices goes up because of advanced technology, so they cost more.

Similarly, treasure-seeking devices are quite pricey because they are intended for seeking treasures. Despite having low sensitivity, treasure-seeking detectors are costlier due to their specialized purpose. One reason why treasure detectors cost a lot is because they can detect deep underground.

Best Treasure-hunting metal detectors prioritize depth range and sensitivity, leading to higher prices.

Coil Options

Some devices let you attach multiple coils, which makes the detector work better for different tasks. On the other hand, some devices do not enable the option of attaching coils, limiting their performance.

Devices with coil options hold more value since they can serve multiple operations in the future. Consequently, devices offering this facility will come at higher prices, while those without it will be cheaper.

Some devices are designed to provide output in the form of a needle, while others provide results through audio. These devices are cheaper as they are based on basic technology. Digital display devices show target IDs on the screen digitally and allow menu selection.

Digital output can tell the user if the metal is iron or silver. Some advanced devices also show the size and depth of the metal. For instance, the device can identify if the target object is jewelry or coins.

Digital devices will be comparatively pricier than their analog counterparts.

The 3D display shows the target object’s shape with colors and graphics. This feature helps determine whether an area is worth digging into or not. 3D output is the most advanced and comes at higher prices compared to the previous two.

In summary, the more intricate the output, the higher the cost.


Some detectors have impressive built-in quality. When using such a device, it will feel lightweight and premium due to materials like carbon fiber and rubber on the exterior.

Therefore, if you are looking for a well-built device, you must consider that it will cost more than a device with a poorer build.


The price of metal detectors varies significantly based on waterproofing features. Some devices are not waterproof and cannot resist water, so they are cheaper than partially waterproof devices. Partially waterproof devices can sustain water splashes without being damaged.

Likewise, devices with complete waterproofing are more expensive than those with partial waterproofing. Complete waterproofing allows the submerging of the coil in the water without any issues.

Devices with waterproofing for underwater use will cost more because they can be used for SCUBA diving and work at great depths. Good waterproofing results in a higher price for the detector.

Here are some of the best Metal Detector Underwater available in the market.


Some devices can use disposable batteries, such as 9-volt, AA, or AAA batteries. Other devices have built-in rechargeable batteries. The price can vary a lot depending on whether the device uses disposable batteries or has a built-in rechargeable battery.

Additional Features

The device has extra features like vibration mode for privacy, headphone support to avoid disturbance, and LED lights for working in the dark. Some devices are heavyweight, while others are lightweight.

Therefore, having a lightweight device, headphones, and vibration features comes at a higher price.


The answer to whether or not there is a difference between metal detectors? is simple. Briefly speaking, metal detectors differ from one another based on their functionality and budget. The ones with advanced features will no doubt cost more than the basic ones.

Now that you understand the difference between different types of metal detectors, we hope you can make an informed decision on which device could potentially serve you best.
