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 CTX 3030 is a well-built metal detector that offers impressive features, though it might be considered pricey for a 'cheap' category. It operates at a frequency of 15 kHz, which provides a good balance for detecting various types of metals, including small and medium-sized targets. The detector includes two coil options—a 17-inch smart coil and an 11-inch DD smart coil—offering flexibility for different search environments.

Its discrimination and ground balance capabilities help reduce false signals and handle different soil types, making it easier to find valuable items. Weighing just over half a pound, the CTX 3030 is lightweight and designed with ergonomics in mind, including an armrest strap for comfort during longer hunts. The IP54 waterproof rating enables it to handle wet conditions such as light rain or shallow water, adding to its versatility.

The detector may be complex for beginners and could be more advanced than necessary for those just starting out or on a tight budget. Given its price and features, it aligns more with mid-range detectors rather than entry-level models. For hobbyists seeking a reliable, durable detector with good sensitivity and user-friendly features, the CTX 3030 represents a strong and versatile choice, especially for those willing to invest time in learning its controls.
