What metal detector detects the deepest?

The depth at which a metal detector can detect objects depends on various factors, including the type of metal detector, the size and composition of the target, the ground conditions, and the settings chosen by the user. Generally, pulse induction (PI) metal detectors are known for their ability to detect objects at greater depths compared to very low frequency (VLF) detectors. PI detectors are often preferred for searching in highly mineralized soils and for finding larger and deeper targets.

One example of a metal detector known for its depth capabilities is the Minelab GPZ 7000. It is a pulse induction detector designed for gold prospecting and can detect gold nuggets at impressive depths. Minelab’s GPX series, particularly the GPX 5000 and GPX 6000, are also recognized for their depth performance.

It’s essential to consider that while certain metal detectors are designed for increased depth, deeper detection often comes at the expense of sensitivity to smaller or low-conductivity targets. Additionally, user expertise and familiarity with the detector’s settings play a crucial role in maximizing its depth capabilities.

If you’re specifically interested in deep-seekers, it’s recommended to explore models designed for gold prospecting or relic hunting, as these activities often involve searching for targets at greater depths. Keep in mind that advancements in metal detector technology are ongoing, and new models with improved depth capabilities may be introduced over time.

How do I choose a good metal detector?

Choosing a metal detector involves considering various factors to ensure it meets your specific needs and preferences. Here are some key considerations to help you choose a good metal detector:

Type of Metal Detecting:

Determine the primary purpose of your metal detecting activities. Are you interested in coin shooting, relic hunting, gold prospecting, or beach detecting? Different metal detectors are optimized for specific applications.


Understand the two main types of metal detector technology:
Very Low Frequency (VLF): Good for general-purpose detecting, coin shooting, and relic hunting.
Pulse Induction (PI): Suitable for challenging ground conditions, beach detecting, and gold prospecting.


Consider the frequency of the metal detector. Higher frequencies are more sensitive to small targets and low-conductivity metals, while lower frequencies are better for larger and more conductive targets.

Ground Balancing:

Choose a metal detector with ground balance control or an automatic ground balancing feature. This helps in adjusting the detector to different soil conditions, reducing false signals caused by mineralization.


Discrimination allows the detector to ignore certain types of metals. A good metal detector should have adjustable discrimination to filter out unwanted targets while still detecting valuable items.


Look for a detector with adjustable sensitivity settings. Higher sensitivity can detect smaller or deeper targets but may also lead to more false signals, especially in highly mineralized soils.

Coil Size and Type:

Consider the size and type of the search coil. Smaller coils are better for target separation and maneuverability, while larger coils can cover more ground. Some detectors allow you to interchange coils for different purposes.

Weight and Ergonomics:

Check the weight and overall ergonomics of the metal detector, especially if you plan on using it for extended periods. A lightweight and well-balanced detector can be more comfortable during long sessions.


Set a realistic budget based on your needs. Metal detectors come in a range of price points, and while higher-end models may offer more features, there are excellent detectors available at various price levels.

Brand Reputation:

Consider the reputation of the brand and read reviews from other users. Established brands with a history of producing reliable and high-performance detectors are often a good choice.

Warranty and Support:

Check the warranty offered by the manufacturer and the availability of customer support. A good warranty provides peace of mind and protection against potential defects.

Educate Yourself:

Take the time to educate yourself about metal detecting techniques, settings, and best practices. Understanding how to use your metal detector effectively enhances your chances of success.

Before making a purchase, it’s advisable to visit metal detecting forums, read reviews, and, if possible, try out different models. Choosing the right metal detector depends on your specific requirements, the types of environments you’ll be detecting in, and your level of experience in metal detecting.
