Minelab Equinox 900 Metal Detector

The Equinox 900 lets you "choose between 6 single frequencies when you have a specific target in mind, or use our revolutionary Multi-IQ technology to automatically employ 5 frequencies at once," which Minelab sums up as working for "all metals, all soils, all the time." Single-frequency hunters get six options to dial in: 4/5/10/15/20/40 kHz.

It's fully waterproof and submersible up to 16 ft (5 m), so beach and bank hunts don't have to stop at the water's edge. Target sorting runs through a fast and accurate 119 high-resolution Target ID with audio control to gauge size and depth, and low-latency wireless headphones come included. Four detect modes, Park, Field, Beach, and Gold, adjust the detector to high-trash areas, coins and artifacts, or target and ground type, with a built-in flashlight and Handgrip Vibration for hunting after dark. The lightweight 3-piece carbon-fiber shafts bring the whole unit to 2.8 lbs (1.2 kg) and pack down to a mere 24 inches (61 cm) for the backpack.
