Metal Detectors Buying Guide

A metal detector is a tool used to locate metallic objects hidden underground, in water bodies, or in other inaccessible areas. Metal detectors have a wide range of applications, including treasure hunting, archaeology, and security.

When looking to buy a metal detector, it is important to consider several factors to ensure that you choose a device that meets your specific needs and requirements.


Consider the purpose for which you need the metal detector. Different metal detectors are designed for different purposes, such as gold prospecting, beach hunting, relic hunting, and coin shooting. Choose a metal detector that is specifically designed for the type of treasure you are looking to find.


Metal detectors come in different prices, ranging from under $100 to over $1,000. Your budget will determine the type and quality of metal detector you can afford. Consider how much you are willing to spend and choose a metal detector that fits within your budget.

Detecting Environment

The environment in which you plan to use the metal detector will also determine the type of metal detector you should choose. For example, if you plan to use the metal detector in saltwater, you will need a waterproof metal detector. If you plan to use it in the ground, you will need a metal detector with good ground balance.


Discrimination is the ability of a metal detector to distinguish between different metals. Some metal detectors are designed to detect all metals, while others are designed to detect only specific metals. Choose a metal detector that has the right level of discrimination for your needs.


Sensitivity is the ability of a metal detector to locate metals that are deep underground or in water. A metal detector with high sensitivity will detect metals at deeper depths than a metal detector with low sensitivity. Choose a metal detector with the right level of sensitivity for your needs.

Operating Frequency

The operating frequency of a metal detector determines its ability to detect metals. Metal detectors with higher operating frequencies are better able to detect smaller and deeper metals. However, they are also more sensitive to interference. Choose a metal detector with the right operating frequency for your needs.

Ground Balance

Ground balance is the ability of a metal detector to adjust to the minerals in the ground. Metal detectors with good ground balance are better able to distinguish between metal targets and ground minerals.

Ease of Use

Consider the ease of use of the metal detector. Metal detectors with simple and straightforward controls are easier to use than those with complex controls. Choose a metal detector that is easy for you to use and that you feel comfortable with.


Consider the warranty offered with the metal detector. Choose a metal detector that comes with a warranty, as this will give you peace of mind in case the metal detector fails.

Customer Reviews
