10 Best Cheap Metal Detectors 2025 in the United States

The MINELAB MANTICORE metal detector stands out in the cheap-metal-detectors category due to its advanced Multi-IQ+ technology, which offers superior power and simultaneous multi-frequency capabilities. This makes it highly effective in differentiating between valuable targets and trash, thanks to the enhanced discrimination and Advanced Target ID features. Users will find the 2D target ID map and rich audio options particularly helpful for precise targeting in various terrains.

The device's waterproof design, capable of submersion up to 16 feet, allows for versatile use in diverse environments, including beaches and goldfields. Additionally, with ten different search modes, it caters to various detecting needs, from inland terrains to specific gold detecting scenarios. The ergonomic design is another plus, as the lightweight and compact structure ensures comfortable usage over extended periods. You can conveniently carry and store it, thanks to its foldable design. Customizable audio controls and integrated lighting features such as a flashlight and backlit display further enhance usability during low-light conditions.

Despite its impressive features, the detector weighs 7.1 pounds, which might be slightly heavy for some users, especially during prolonged use. Moreover, it requires a lithium-ion battery, which is included but represents an ongoing cost as batteries need replacement over time. The MINELAB MANTICORE is a powerful, versatile, and feature-rich metal detector for enthusiasts looking for an effective device without breaking the bank.

The Garrett Ace 400 Metal Detector is a solid choice for those looking for an affordable yet effective metal detector. One of its key strengths is the 10 kHz operating frequency, which is higher than many entry-level detectors, allowing it to detect a wide range of metals more effectively. The adjustable frequency feature helps reduce interference, making it more stable in various environments. The enhanced iron resolution is another standout feature, helping you distinguish between valuable finds and junk metal more easily.

The coil size, at 8.5” x 11”, is a good balance for depth and sensitivity, and the waterproof design means you can use it in wet conditions without worry. The device also includes electronic pinpointing, which can save you time by precisely locating your targets. Weighing 5.48 pounds, it’s relatively lightweight and comes with adjustable ergonomics for comfortable extended use. The inclusion of accessories like headphones, a rain cover, and a coil cover add value to the package.

However, there are a few drawbacks. The 5-hour battery life may be limiting for longer treasure hunts, so carrying extra batteries is advisable. While the LCD display is user-friendly, some users might find the plethora of settings a bit overwhelming at first. In summary, the Garrett Ace 400 offers good value for its price, especially for beginners or casual hobbyists, but may require some adjustment for optimal use.

The Minelab X-Terra PRO is a strong contender in the affordable metal detector market, particularly appealing to hobbyists and beginners looking for versatility and reliability. One of its standout features is the Pro-Switch Technology, which allows users to switch frequencies, enhancing its ability to detect targets deeply in various conditions. This is a significant advantage for those who want to explore diverse terrains without compromising performance.

Additionally, the X-Terra PRO is fully waterproof, enabling users to search for treasures underwater up to 16 feet deep, making it ideal for beach outings or river explorations. It offers three distinct detect modes—Park, Field, and Beach—tailored for different environments, which is excellent for those who may frequent both urban parks and sandy shores. The built-in flashlight and backlit keypad ensure that searches can continue into the evening.

Another positive aspect is its lightweight design at just 2.9 lbs, making it comfortable for extended use. It's also compact enough to fit easily in a backpack, appealing to those who might travel with their detector. The audio control system is a nice touch, as it helps distinguish between valuable targets and junk, further enhancing the user experience. There are some weaknesses to note. While it offers solid features, some users may find that the sensitivity and depth detection can vary based on soil conditions or the type of target, which may require some adjustments. The LCD display, while functional, may not provide as much detail as more advanced models, possibly limiting serious treasure hunters. Lastly, the material feels somewhat plastic, which could raise concerns about durability over time, especially with extensive use. The X-Terra PRO is best suited for casual treasure hunters or those exploring new hobbies rather than professionals seeking advanced capabilities.
