Modern metal detectors can have a range of features, and it’s easy to lose track of what functions you really need and what is just good marketing.
Some features are important to know about even for buyers on a budget. Sometimes the cost of having certain features is often worth paying a little more because you really are getting more for your money. The best features will reduce the problem of interference or false signals, which is the main issue a user faces when using a detector.
7 Best Metal Detectors for the Money
1. Minelab Equinox 600
If you have no budget limits, the Minelab Equinox 600 is the best metal detector for the money.
The main reason for that bold statement is that this detector reduces the time spent digging for worthless metal scrap, bottle caps, and other metal debris better than anything else available.
Okay, that sounded more complicated than it needed to be. Most metal detectors use a single frequency and this works pretty well for beginners. But, using a single frequency doesn’t work really great for anything and it doesn’t give the brains of the metal detector a lot to go on.
Using only a single frequency results in the user being able to detect metal objects in normal conditions, but not having enough information to accurately determine if the object is likely to be jewelry, a gold nugget, coins, or something much less interesting. This means that the detectorist will also be more likely to miss weak signals or waste time on junk.
Where the Minelab Equinox 600 metal detector stands out is that it scans with 5 frequencies simultaneously. This not only means you are scanning with the optimal frequency for whatever metal is down there, but it allows the electronics to work with a much more complete picture about what metal may be under the ground. This lets you find treasure even when it’s right next to trash.
The Minelab Equinox 600 is an entirely sealed unit, making it waterpoof to 10 feet which is deeper than most people are likely to ever hunt. It runs on an internal rechargable battery with a 12 hour run time. The detector has a mode for dry sand, wet sand, and submerged treasure hunting. This can be very useful for the waterline area, which many other treasure hunters can not search due to false positive signals.

Features to look for in a metal detector
Discrimination, notch and ground balance are three essential metal detecting concepts you need to understand to get started.
Discrimination is the term referring to the metal detector’s ability to recognize a valuable item surrounded by other metal objects, minerals, or debris. Therefore, it is one of the most important features on any metal detector.
Fortunately, this can be found in all price ranges and even on the top cheap metal detectors. Quality and consistency can vary, but good discriminators can be found even on the beginner detectors at the bottom of the list below.
The term notch is also used as a part of the discrimination system. It is useful to reject materials that are creating false readings.
The notch provides a kind of threshold value, which can be set at a specific point. This allows the detector to reject any item outside of the band, so this is a refined setting.
The ground balance setting allows you to filter out the noise caused by various minerals in the earth. This includes salts and iron particles.
Soil with high concentrations of minerals can give signals that mimic a target, so filtering out this noise is critical to your metal detecting. The ground balance setting can be manual, automatic, or continuously adjusted.
Frequently Asked Questions (FAQ)
What conditions affect how deep the metal detector can function?
Magnetism, conductivity, size and shape of the object are main factors in determining how well the metal detector will perceive an item. The length of time the object has been underground also affects detection.
What is the best way to use the sensitivity controls?
Sensitivity refers to a metal detector’s capacity for responding to the electromagnetism of conductive materials.
The best way to understand the sensitivity controls is to think of the sensitivity increasing the metal detector’s ability to detect even the smallest amounts of target substances. This often has the effect of increasing the amount of debris and junk your detector recognizes; however, it also allows the detector to penetrate deeper into the earth.
What can you do to avoid false signals?
False signals happen when a metal detector’s settings respond to undesired substances. This includes minerals in the earth like iron oxides and magnetite, for example. Gold is often surrounded by iron oxides, which is good to know. Certain types of clothing can also produce false signals.
Avoid footwear that has any metal eyelets or other parts. Take off all metal jewelry, and make sure you stay clear of power lines. If you hunt with a friend, keep a good distance because a metal detector can pick up on the metal in the other device if it’s too close. Make sure the control box of your detector doesn’t have a build-up of moisture. Review your swinging technique to avoid false readings.
Should people with pacemakers be concerned about their safety when using a metal detector?
Pacemaker manufacturers are aware of the potential for electromagnetic interference from cellphones, CB radios and security metal detectors used at airports. The electromagnetic signals coming from a hobby metal detector are much weaker than these other signals, so there is no threat of interference. In addition, the radius of the electromagnetic field is limited to a few inches from the search coil, which is a safe distance from the human torso.
What Are The Best Metal Detector Brands?
This article reviewed some of the most trusted brand names in the metal detector industry. Each product we reviewed can be evaluated according to the combination of features in relation to the price.
Advanced features will enable you to get more out of the experience by enabling refined searches in all kinds of conditions, but the price goes up. The basic metal detectors from top brand names like Garrett and Minelab will give you everything you need to get started within your budget.
How Do Metal Detectors Work?
Metal detectors function by leveraging the technology of electromagnetism in a specific way. The design of a metal detector allows it to detect objects that produce an electromagnetic field. The discrimination and sensitivity settings allow the hunter to adjust the field’s range according to various conditions.
Correct Way to Use A Metal Detector
Stay within an inch of the ground without scraping, and maintain the same level throughout the swing. Your sensitivity setting might also be set too high, which will make the detector pick up on smaller conductive metal scraps. Always refer to the owner’s manual for detailed instructions on the particular model.
What Is Ground Mineralization?
Ground mineralization refers to the amount of magnetism created by the mineral density in the soil, which often has a reddish color. The metal detector reacts to the magnetism, so highly mineralized soil permits less penetration. It can also cause false signals, which makes it harder for the metal detector to separate junk from valuable items.
The settings on advanced metal detectors allow you to adjust for these conditions, so always review the sensitivity and discrimination controls when hunting in highly mineralized soil.
Is Coil Size Important?
The size and shape of the coil is important, but bigger isn’t always better. For searching in tight areas, an elliptic-shaped coil that is smaller will get better results.
The standard coil size is eight inches, and this performs under most conditions. Larger coils will perform better under conditions where there is minimal amounts of trash and mineralization. However, large search coils are often heavier, and this can affect your ability to maintain the coil head equidistant from the ground, which is critical for any good searching technique.
What Is Adjustable Sensitivity?
The sensitivity control is an adjustable setting that is designed to be used according to the various types of terrains you could encounter. Just like the transmission of a car, there is no single setting that will work optimally for all environments.
Lower the sensitivity whenever there are power transformers nearby, ground mineralization, radio stations and other types of interference. The trade-off is a slight loss of the total depth you can detect underground.
What Is Ground Balance?
Ground balance refers to an advanced feature that isn’t available on every metal detector model. It permits the detector to adjust for the highly mineralized soil content and get a greater detection depth.
The ground balance setting removes the interference caused by the mineral’s magnetism inside of the soil. This allows you to hear the signal created by the target item without the additional noise.
What Is Notch Discrimination?
Discriminators have settings that can be adjusted, and advanced models have more refined and finely tuned adjustment settings to help you remove the junk from your search. This will allow you to swing the metal detector over items without having them register. Notch discrimination functions as a filter, so only the most likely targets will create a signal, and audio signals also give you information about the target.
Is the Frequency Important?
It is very important to understand how frequencies affect your ability to find valuable objects. Objects can be different sizes. The orientation and depth of the object also affects the frequency needed to detect it, for example. High frequencies detect small objects, and low frequencies penetrate deeper into the ground.
Adjustable settings give you more control, and multi-frequency devices allow you to refine your search settings.
How Deep Will A Metal Detector Go?
Unfortunately, there is no simple answer. The depth depends on a variety of factors as well as the power and the settings used on the metal detector itself.
The amount of ground mineralization can affect the total depth the metal detector can read. The same metal detector will be able to penetrate deeper into ground that has low mineralization, for example. However, if the target object is large, it can also be detected at a deeper level than a smaller object at the same depth.
What Accessories are Important?
Basic accessories for hunting with a metal detector include items to make the hunt easier, but you have to think ahead to the moment when you plan to dig for treasure as well. This includes a carrying bag for the metal detector, headphones and optional pinpointing probes. Digging equipment, flashlights and cleaning gear are also essential accessories.
Do You Need A Pinpointer?
A pinpointer is an optional item, but many hunters refuse to work without them in the hunting kit. They allow you to quickly locate the target after localizing the area where you plan to dig. The pinpointer also helps you to get the target out of the ground without the guesswork of how wide or deep to dig. Many pinpointers also come equipped with external LED lights for night hunting, which also assists in the searching process.
If a pinpointer could help in your treasure hunts, be sure to see our list of the best metal detector pinpointers.
Are All Metal Detectors Waterproof?
Not all metal detectors are waterproof, so you should always check the technical specifications if you plan to hunt near bodies of water or in wet grass.
This is another advanced feature found on the more expensive metal detectors. Cheaper detectors use a single frequency, which is fixed. The length of the wave determines how deep the detector can get into the ground because low frequencies can go deeper, and higher frequencies are able to detect targets with a smaller size.
Very Low-Frequency (VLF)
Very low frequency technology, or VLF, is a very popular method used in many modern metal detectors for receiving and interpreting the electromagnetic fields given off by metal target objects. It is made from a transmitter and receiver coil. The first is the outer coil loop, and the second is the inner coil loop.
The frequency is sent out through the transmitter coil. The receiver coil functions as an amplifier for the signal so that it can be interpreted by the control box. It can also differentiate between different types of metals based on their electromagnetic properties, which are picked up with the signal.
Pulse Induction (PI)
Pulse induction technology is used on some metal detectors instead of VLF. An example of a pulse induction device is a metal detector that uses a single coil for both the transmitter and receiver, but they might also be designed using several coils.
The technology is based on the short bursts of electrical currents sent through the coil or coils, and these are called pulses. The pulse creates a magnetic field, which reversals polarity and causes the object to emit an opposite magnetic field. The reflections from the target object indicate its size and shape.
These types of metal detectors can be found on our list of the best pulse induction metal detectors.
Metal detectors have discrimination and sensitivity settings that allow you to find valuables while sorting out junk and false signals.
Each unit has different features, and some of them are more advanced. Before you go hunting, practice using the discrimination settings on various objects including common junk as well as valuable coins and relics so that you become familiar with how the detector sounds when registering each of these items.
Practice filtering out the junk, debris and scrap metal to refine your searching abilities. It can be best utilized after practicing with target coins and rings with a mixture of debris, scraps and bottle caps. This will help the user to learn the sounds associated with valuable treasures as well as the sounds of the metal debris and scraps.
