What is the Best Metal Detector for Kids and Adult?

The metal detector is an excellent device for those who are interested in treasure hunting. It can help you to hunt gold and silver at the beach or even underwater. But there is a wide range of metal detector brands on the market so that you are wondering what's the best metal detector.

We create the guide to help you purchase the best professional metal detector under $300. This tutorial will tell you what features you should consider when buying a metal detector. Then you will be able to identify the most accurate metal detector according to its performance and features.

What is a metal detector?

A metal detector is a device to hunt metal objects buried underground like jewelry, gold and silver. It works as it sends a specific frequency signal into the land. If it detects any metal objects nearby, the metal’s electromagnetic signature will be feedback to the metal detector. By different sounds to know what’s the kinds of metal.

What does a metal detector detect?

The metal detector can detect a wide variety of valuable metals buried under the land, which means you can be prospecting gold and silver, hunting coins and relics. Since not each metal detector can detect all kinds of metals, you should choose the most suitable types.

Types of metal detectors and their uses

Choose what metal detectors types will depend on your different use purposes. There are 3 common types on the market: a metal detector for gold, underwater metal detector, and Multi-Frequency metal detectors.

Metal detector for gold

The metal detectors for gold are used to find metals buried underground, such as gold and silver. Typically, they are cheaper and easy to buy. Furthermore, this type of metal detector is lightweight and durable, making them best suited for beginners and kids. You can use them at the beach and land, most of them are waterproof. 

Underwater metal detector

Underwater metal detectors are designed specifically for searching coins or gold underwater, so if you plan to hunt metals in rivers, an underwater metal detector is better than a VLF detector. They are more expensive, so this kind of metal detector may not suit those who don’t want to invest too much money in metal detectors.

Multifrequency metal detectors

Multifrequency metal detectors can be either for professionals or beginners. It enables you to pinpoint a target accurately to detect the metal objects you want. You can use them on the beach and land or underwater.

Best metal detector for kids and adult

Tilswall metal detector is the best value for money metal detector to buy. It has a 10’’ waterproof search coil, so you can safely use it on the beach and land and even detect it underwater. The DISC modes help you distinguish different metals, and we’ll give you a pair of headphones and a small foldable shovel. Connect the headphones to the audio jack on Tilswall metal detector. When the detector identifies each metal will emit different sound and display on the LCD screen to accurately and conveniently detect objects you want.

The Tilswall metal detector is more comfortable to hold than many others, which is with ergonomic design handle, allow you adjustable stem extending from 35’’ to 45’’, and it weighs 2.35 pounds only. It's the best suit for kids and adults.

Best metal detector for gold, coins, and jewelry

A metal detector with a depth range of up to 8 inches is the best to choose if you’re hunting for coins and gold at depth of soil. A good detector for gold and jewelry should have DISC mode and have an automatic ground balance, so you can quickly and accurately detect objects you want. Choose a waterproof metal detector, which is important when searching for gold at the beach, to reduce the lost investment risks when you search for gold at the beach.

How to choose the best metal detector

Choosing the best metal detector often has some evaluation criteria. We’ll show you a few crucial features that you should consider before purchase a metal detector. 

Are you a beginner or professional

If you are metal detecting for the first time, buying an easy-to-use metal detector will reduce the learning times compare to purchase one complicated detector. Thus, once you receive it, you can be using it for treasure hunting right away.

What you want to detect and where use

When deciding what type of metal detector to buy, you’d better consider what you want to hunt, jewelry, gold, silver, coins and relics, or other metals. Most metal detectors are used for hunting coins and jewelry. For this purpose, you only ensure that not buy a pulse induction (PI) detector. The PI detectors are expensive than the lower frequency detector. And there's no need to spend more money on features that you can't use. A single frequency detector is enough.

In addition, think about where you plan to use your detector, beach and land, or underwater. If you want to find gold and silver on the dry soil, you don’t need to buy a waterproof detector, but you will be hunting on a beach or underwater. The waterproof metal detectors are your first choice.

Ground balance

There are some metallic minerals in the soil, especially in areas where the soil is mineralized. These will interfere to metal detector’s accuracy. So, to detect the coins and gold accurately, you should note whether the metal detector features ground balance. A metal detector with ground balance features can ignore the metallic minerals in sand, and this will help you hunt gold and silver properly. There are three common types of ground balance.

  1. Preset ground balance

These types are unable to adjust by yourself. The manufacturer has been set at a particular range and only allows the metal detector to exclude the interference within the range.

  1. Automatic ground balance

The metal detector has automatic ground balance features that can automatically adjust its sensors to ignore interference. You needn’t do anything. 

  1. Manual ground balance

By definition, a metal detector with manual ground balance means you can adjust it according to your use target. But this is a challenge to how to correct settings for beginners. So, if you are a beginner, we recommend choosing the metal detector with automatic ground balance.

Search coil

Another feature that you should consider is the metal detector search coil, and there are double-D, concentric and spider coils. The common use is double-D and concentric coils; Double-D coils can detect a wide range than concentric, but can’t find metals buried very deep. On the other hand, the concentric coils will help you detect depth better than double-D. Moreover, if you want to hunt amid bushes and grass, you should choose a metal detector with a sniper coil; it has better maneuverability.

Besides, also need to consider the search coil size. Remember that not the largest, the better. Use which size coil depend on the soil conditions and mineralization. A large coil needs to deal with more frequency in mineralized ground, lead to reduce the depth. And larger coils will be heavier than small ones. 

Depth indicator

Usually, depth indicators range from 1-12 inches. Though it often depends on the soil types you want to hunt, the interference underground will reduce the metal detector’s depth. But the depth indicator of 12 inches will offer a better depth than 1 inch. 


The disc mode on the metal detector will help you detect what you are looking for exactly. This feature will be handy. It will help you save lots of time on your targets. Through the disc mode to disc bottle caps and nails, and find the jewelry, coins and gold properly. 

Sensitivity meter

The sensitivity on the metal detector is a great option, and you can set the sensitivity meter for a different purpose. If you want to hunt at a larger area, set it to low, and when detecting on smaller areas, set high sensitivity. 

Operating frequency

The low-frequency metal detectors can detect gold buried under deeper soil, but a higher frequency metal detector might best hunt small objects. The high-frequency metal detectors through their high-frequency signal to find small metals. Frequently, most metal detector’s operating frequency ranges from low to medium, for beginners or hobbies are enough.


It would help if you were not want to carry a heavy machine when hunting. So, pay attention to the metal detector’s weights, especially if you plan to buy it for your kids.

Final words

You don’t need to spend a substantial investment when buying a metal detector. Get the best value for money metal detector only. This article list complete factors to consider when purchasing a metal detector. We hope this can help you.
