Metal Detector Depth Comparison Chart

There are many different types of metal detectors available in the market. Each company has its customer packages and makes metal detectors more appealing with accessories.

To help customers choose the right metal detector, use depth comparison charts. These charts show how advanced metal detector technology is and what type of detector it is.

Some devices are capable of providing greater depth, while others only work at shallower depths. Metal detectors also have other features that perform accordingly.

Most people are curious to know the exact depth of metal detectors, and the graphs and charts assist them in finding that information.

Before we begin keep in mind that the depth results may vary according to the ground condition and terrain type.

Why Do You Need To Know Metal Detector Depth Comparison Chart?

Customers need to understand the details and functions of the many available models in the market.

It can be difficult to comprehend when the purpose is the same but the functions differ. Information presented in the form of charts or graphs is easily understandable for users.

Metal Detector Depth Comparison Chart Based On The Size Of Target Objects:

Metal detectors are grouped based on the size of objects they can detect for easier understanding. There are four basic categories, intended solely for hobby purposes. Industrial metal detectors have their separate categories. The four categories based on the size of objects are as follows:

Depths Lowest Depth Better Depth Deeper Depth Deepest Depth

Gold Nuggets:

These high frequency metal detectors have very shallow depths because of their high frequencies, which limits their ability to reach deep depths.

However, they have amazing sensitivity and can detect even the smallest pieces of gold nuggets. When it comes to larger objects, these devices fail to perform and are not suitable for deeper depths.


Coins are medium-sized target objects and are not considered small targets. They serve as excellent initial options for metal hunters, as they are commonly available and easily detected. Many people unconsciously drop their coins.

 Compared to gold nuggets, coin devices have better depth. While gold nuggets are usually found on the surface of the ground, coins need to be properly dug to be found.

Approximately 1-2 feet depth is required for detecting coins. Many old coins are lost and buried underground. Coins have larger diameters, requiring greater depths for detection.

Follow the Metal detecting tips for coins to find more in less time.


Relics are larger target objects compared to coins. They are relatively easier to discover than coins and gold nuggets, as they are present at deeper depths. Devices designed for relics have better depth potential due to reduced frequency.

High-frequency devices used for coins cannot detect gold nuggets, but they can find relics. If a device operates at a single frequency, it will work the same for both coins and relics. The depth potential for a relic detector is around 3-4 feet deep.


Treasures are found at the deepest depths. The best treasure-hunting metal detector can find buried collections of coins, jewelry, and other valuable items.

People usually bury treasures deep for safety or because they forget where they put them. The appropriate depth for detecting treasures ranges from 3 to 5 meters.

If a brand claims to achieve greater depths than this range, it is important to thoroughly check or research to ensure the claim is true.


In this article, we have discussed the metal detector depth comparison chart and compared different metals found underground.

Now you have the data you need to effective choose a metal detector compatible with your needs

Metal detectors are made for different depths and have varying capabilities and speeds. The purpose of a chart is to provide an easy understanding of the depth of different items.
