Its waterproof design allows operation up to 16 feet deep, which is great for those who want to hunt in water. The customizable audio controls and backlit display enhance usability in different conditions, making it easier for users to detect targets in low-light environments. It may take some time for new users to fully master its features and settings.

The MINELAB Equinox 900 is a solid choice for anyone looking to dive into metal detecting, especially if you're interested in treasure hunting in various environments, including underwater. One of its standout features is the simultaneous multi-frequency capability, which allows it to pick up signals effectively across different metal types and soil conditions. This is particularly useful for beginners and seasoned hunters alike, as it simplifies the process of finding valuable items without the need to frequently adjust settings.

The fully waterproof design is another major advantage, enabling users to explore beaches, rivers, and lakes up to 16 feet deep.

The Minelab CTX 3030 is a high-quality metal detector designed for users who want reliable performance in various environments, including underwater detection thanks to its waterproof design. Its operating frequency of around 15 kHz provides a good middle ground, allowing it to detect a range of metal types while maintaining decent depth. The included 17" Smart Coil and 11" DD Smart Coil offer flexibility—larger coils help detect deeper targets, while smaller coils provide better sensitivity for smaller objects. Advanced ground balance capabilities reduce interference from mineralized soils, making it suitable for challenging terrains. The discrimination options allow differentiation between types of metals, which is useful for focusing on valuable finds and ignoring junk. Battery life and wireless headphones add to user convenience during longer hunts.

On the downside, the unit is somewhat heavier than more basic detectors, which might be tiring over extended use. Additionally, although it offers multiple search programs, beginners may find the range of settings a bit complex at first. Considering these factors, the Minelab CTX 3030 is well suited for serious hobbyists or professionals who want a versatile, feature-rich detector that performs well in diverse conditions, including underwater, but it may be more than casual users need.
