How to make a metal detector go deeper

Ever wondered how to make a metal detector go deeper? so that you can maximize the investment of time and money you have spent on metal detecting.

We are here to help you find out in what ways you can achieve this objective without you having to experiment yourself.

How do other people find treasure where we find nothing? What are we missing? Many times, you run across an area that has been detected to death. How do you find treasures that others have passed over?

How deep metal detector can detect? Is a question that can be difficult to answer. The best way to find the treasure located in the depths is to make your metal detector detect deeper in the ground. In this article, we’ll show you how to make a metal detector go deeper.

Can a metal detector go deeper?

It has a few requirements.


It depends on your technology and what type of metal detector you bought. Is it a branded or cheap detector that cannot give you accurate potential depth? Or is it not upgradeable?


If your manufacturer provides you with support or accessories, it will help you go deeper into the ground. Make sure your manufacturer provides you with this support.


Make sure you select the best metal detector device that can go deeper.

Find Out the Pros and Cons Of Going Deeper

Going deeper has some pros as well as cons. We will discuss these one by one.


More finds and time-saving:

Having a metal detector that can reach greater depths improves your odds of discovering treasures during your hunts. When you can search deeper, it increases your chances of finding valuable items.

Furthermore, searching at greater depths not only saves time but also lessens the physical effort needed for digging and detecting multiple times at the same place.

A metal detector with enhanced depth capability gives you precise information about the depth at which you should dig.


Ignore small objects: 

  • If you go into depths, your device will start ignoring small objects. For example, if you are looking for coins, you might miss one or more coins. Similarly, when detecting relics and gold, you might miss gold nuggets.
  • Your device may become unstable as you go deeper, experiencing distortion due to soil mineralization. This is why many brands specify their maximum depth ranges to minimize instability.
  • If you dig deeper, you’ll need a larger coil, making the detector heavier and harder to use.

How to make a metal detector go deeper 

Use a large coil: 

If your manufacturer offers large coils, they will support you in digging and hunting deep. The larger the coil, the deeper it will penetrate, increasing the chances of detecting objects.

Increase sensitivity or gain: 

Old devices use the term “gain,” while new ones use “sensitivity.” If you increase the sensitivity of the coil, your detector will go deeper.

By increasing the sensitivity, you will not need to change the coil; you will only need to optimize it. But remember, if you go deeper, there might be more distortion.

So increase sensitivity until it stabilizes. Sensitivity plays a very important role in detection so we recommend you learn in-depth about metal detector sensitivity settings.

Decrease frequency: 

When going deep into the ground, you need to decrease the frequency of the device. Signals with longer wavelengths penetrate deeper when their frequency is decreased.

When to decrease frequency: If your device is multifrequency, lower frequencies provide more depth. For example, if you have frequencies of 5kHz, 10kHz, and 15kHz, using 5kHz will provide more depth.

To decrease discrimination, use iron discrimination, notch filters, etc. This will help by removing specific metals, but it may reduce depth. This is because your device struggles to detect those signals. To go deeper, you need to turn off discrimination and use the all-metal mode.

Note: Increasing discrimination will compromise depth. To maximize depth, work in all-metal modes.

You might want to try PI detectors instead of VLF ones. Pulse induction detectors can detect objects deeper. PI detectors work well for both small and large objects, providing maximum depth potential.

Wear headphones: 

Wearing headphones will help you hear your targets better at greater depths. With sensitive settings turned to maximum, you’ll hear a lot of noise, and the headphones will help you distinguish treasure from trash.


So, now you know how to make a metal detector go deeper. I hope this article has helped you understand the adjustments that can be made to your metal detector to detect at greater depths. And when you find yourself outperforming others, be a good sport and share these hints with them too.

While changing the settings on your metal detector can help you detect objects deeper. If more depth is truly what you require, then we recommend you upgrade your metal detecting equipment to one with a wider depth range so you can achieve your goal relatively easily.
