The flexibility of three detect modes—Park, Field, and Beach—makes it suitable for different environments, whether you're in a high-trash area or looking for fine artifacts. The built-in flashlight and backlit keypad enhance usability during nighttime searching, and the option for audio control, which allows you to distinguish between different targets, adds another layer of sophistication.

The MINELAB Equinox 800 is a versatile waterproof metal detector designed for both beginners and experienced treasure hunters. One of its standout features is the simultaneous multi-frequency technology, which allows it to detect various types of metals effectively, making it suitable for different environments, whether on land or underwater. With a depth rating of up to 10 feet, this detector is perfect for beachcombing or exploring rivers and lakes.

The device offers four detect modes tailored for specific needs—Park, Field, Beach, and Gold modes. This provides users with flexibility depending on where they are searching.

On the downside, the price point may be higher than entry-level models, which might deter newcomers. Additionally, while the device is user-friendly, those new to metal detecting may need to spend some time familiarizing themselves with its features and settings to maximize its potential. The product’s weight, though manageable, is slightly on the heavier side compared to comparable models, which could be a consideration for those who prefer a lighter option.

The Garrett ACE 300 Metal Detector features a waterproof search coil that allows you to use it in shallow waters, making it versatile for beach and river hunts. The detector includes useful accessories like volume control headphones, an environmental cover, and a search coil cover, which enhance its usability and protection during use.

Its adjustable length and relatively light weight (5.13 pounds) add to its ergonomic design, making it comfortable for prolonged use. The 7" x 10" search coil size allows for a good balance between depth and coverage area, suited for various terrains. The device is powered by 4 AAA batteries, providing a decent battery life of approximately 25 hours, which is convenient for extended outings.

The ACE 300 also features an IP54 rating, offering limited protection against dust and splashes, though it is not fully waterproof beyond the search coil. One drawback is that it does not include ground balance settings, which might affect performance in highly mineralized soils. Sensitivity and discrimination settings are available, helping to filter out unwanted metals and improve detection efficiency. The LCD display is user-friendly, and with 8 detection programs, it caters to both beginners and more experienced users. However, the lack of a fully waterproof design limits its use in deeper waters. The Garrett ACE 300 is a solid choice for hobbyists who need reliable performance on land and in shallow water.
