Types Metal Detectors

The type of metal detector you choose depends on what you are looking for and the location of your hunt. There are four main types of metal detectors- gold detectors, land coin detectors, multipurpose detectors, and beach and underwater detectors.

Beach and underwater detectors are used to detect the presence of a metal in the water or under beach sand. These devices are more robust, water-resistant, and waterproof.  This makes them rust-resistant warding off corrosion. Their opposite is the land coin detectors which are used for finding metals in the ordinary dirt. 

Gold detectors are used to specifically find gold. They use high frequencies to differential gold and other metals. Such a detector is useful in gold-rich areas since you are unlikely to find natural gold elsewhere.

Multipurpose detectors can find some gold as well as other metals. It is suitable for beginners who have no experience in this field. Therefore, if you do not know which one to buy, a multipurpose detector is the way to go. It gives you a variety of options on what and where to hunt.

Buying Guide

Metal detecting hobby can be confusing when you are a beginner. One, there are a lot of terminologies involved, not to mention the variety of brands with different features. You do not need to have extreme knowledge of metal detecting gadgets for you to be a successful bounty hunter. However, before buying a metal detector, you need to consider the following factors.

  • Weight

Weight is one of the most overlooked factors but to succeed in treasure hunting it must be a consideration. You do not want heavy equipment that will exhaust you. The best metal detector should be lightweight so that you can swing it around for long without fatigue.

  • Operating frequency

This is the speed at which your machines oscillate to create a magnetic field which in turn detects metals. A higher frequency is more sensitive to small items while a low frequency scans deeper. A device with a frequency range of between 5 – 10 kHz is enough for general detection especially if you are a beginner.

  • Discriminator

Nothing is frustrating like digging out for long only to find a worthless bottle cap. That is why professional metal detectors have a discriminator that ignores some targets. You achieve this by setting out a certain threshold of conductivity and eliminating anything below this value. 

  • Depth indicator

This refers to the estimation of how deep on the ground you treasure is. Most modern metal detectors have basic depth features that tell you how deep you should dig.  It is important to note that this is an estimation and the accuracy may vary greatly depending on the detector. Always go for detectors that have a depth indicator with high accuracy.

  • Ground balance

The ground always has some other metals such as iron. Such metals can interfere with the ability of your detector to identify treasure targets such as coins and jewels.  Ground balance is the ability to bypass these other minerals in search of more valuable targets. Most beginner metal detectors come with a preset ground balance that works in most searching environments. However high-end detectors have an automatic ground balance that changes with the environment.

  • Target identification

This is one of the most important features to consider in a metal detector for you to differentiate between nickel, silver, gold, or junk. The signal can be an audible high pitched beep for valuables and low tone for junks. In more advanced metal detectors the target ID output is visual and appears on an LCD screen. This is often a number between 0-99 depending on conductivity and gives you an idea of the probable metal.

  • Sensitivity

This is the ability to detect the metal from a distance. Metal detectors with sensitivity control are used in areas with low mineral levels. It is advisable to lower sensitivity in areas with high mineral levels.


Choose your detector depending on your level of experience, the location you want to perform the hunting, and the type of metal you want to hunt.
