Minelab Equinox 900 Multi-IQ Metal Detector with Backpack

The Equinox 900 ships with two factory coils: an 11-inch Double-D round coil (EQX 11) for ground coverage and depth, and a 6-inch Double-D round coil (EQX 06) for working tight spaces, trash-heavy sites, and gold prospecting around bedrock. Both coils include skidplates to protect the windings from abrasion. The dual-coil setup gives you versatility without purchasing optional coils immediately after unboxing.

The Equinox 900 carries an IP68 waterproof rating and is submersible to 5 meters (16 feet), covering the control box, shaft, and coils. You can snorkel shallow reefs, wade chest-deep rivers, hunt in heavy rain, or detect along surf zones without a housing or waterproof bag. The internal lithium-ion battery is sealed, and all connectors are waterproof, so immersion hunts won't damage the electronics.

Multi-IQ transmits multiple frequencies simultaneously (the Equinox 900 combines 4, 5, 10, 15, 20, and 40 kHz signals), which stabilizes target IDs in mineralized ground, wet salt sand, and mixed-trash sites where single-frequency detectors chatter or lose depth. Single-frequency mode lets you select one of the six frequencies when you're targeting a specific metal or soil condition. Most detectorists run Multi-IQ for general hunting because it handles ground phase shifts without manual retuning. For specialized coin or best metal detectors for coins work, some hunters prefer a fixed frequency for maximum depth on high-conductivity silver.

The Equinox 900 displays 119 target ID segments: ferrous targets range from -19 to 0, and non-ferrous targets range from 1 to 99. This resolution lets you distinguish between iron nails, aluminum foil, nickels, pull-tabs, zinc pennies, copper pennies, clad coins, and silver based on the numeric readout and audio tone. The discrimination grid has 119 accept/reject segments, so you can notch out specific trash ranges (like pull-tab IDs in the 12 to 18 zone) without losing adjacent good targets.

The Equinox 900 runs on an internal 3.7V / 5100 mAh lithium-ion rechargeable battery. Minelab does not publish a specific runtime hour estimate in the tech specs because actual battery life depends on settings: running maximum sensitivity, wireless headphones, backlight on high, and fast recovery speed drains the battery faster than moderate sensitivity with wired headphones and backlight off. Field reports from our team suggest 8 to 12 hours of typical hunting on a full charge when running wireless audio and moderate sensitivity. The detector charges via the included USB cable, and you can use a portable power bank in the field for extended trips.

The Equinox 900 has eight preset search modes: Park 1 and Park 2 for coins and jewelry in turf, Field 1 and Field 2 for relics and larger silver in pastures and old homesteads, Beach 1 and Beach 2 for saltwater and freshwater beaches, Gold mode for nugget prospecting in mineralized ground, and All Metal mode for maximum depth with no discrimination. You also get a Custom User Profile slot where you can save your own settings (sensitivity, recovery speed, iron bias, tone breaks, discrimination pattern) for a specific site or target type. Pinpoint mode is available across all profiles for precise target location before digging.

The Equinox 900 includes a dedicated Gold mode optimized for sub-gram nuggets in hot ground, and the 40 kHz frequency option gives you sensitivity to small gold that lower frequencies miss. The 6-inch coil shipped in the box is ideal for working around bedrock cracks, ironstone, and trash in gold country. Multi-IQ also handles mineralized soil better than single-frequency VLF detectors, reducing ground noise that masks faint nugget signals. The Equinox 900 is a capable nugget detector for shallow alluvial gold and specimen hunting, though dedicated pulse-induction machines still outperform it at depth in extremely mineralized ground.

The Equinox 900 supports three audio output options: the included ML 85 low-latency wireless headphones, wired headphones via the 3.5mm (1/8-inch) jack on the control box, and the built-in loudspeaker. Wired headphones are useful when you want to conserve battery (wireless audio draws more power) or when you're hunting in areas with radio interference that affects Bluetooth connections. Minelab also sells waterproof wired headphones as an accessory for full-submersion detecting where you need audio underwater.

Recovery Speed controls how quickly the detector resets after detecting a target, which affects target separation in trashy ground. Higher recovery speed settings let you distinguish between closely spaced targets (a silver dime next to a nail, a gold ring near a bottle cap) because the detector processes each signal faster and doesn't mask the second target. Lower recovery speed gives you slightly better depth on isolated targets in clean ground because the detector integrates the signal longer. We run higher recovery speeds in tot lots, old fairgrounds, and park sites with dense trash, and lower speeds in open fields or beaches where targets are spaced farther apart.

Iron Bias adjusts how aggressively the detector rejects ferrous targets and ambiguous signals that fall on the edge between ferrous and non-ferrous ranges. The scale runs from 0 to 9: lower settings (0 to 3) reveal small non-ferrous targets hiding near iron, useful when hunting for gold jewelry or small relics in nail-contaminated sites; higher settings (6 to 9) speed up hunting by ignoring borderline signals and reducing the chance you'll dig rusty iron that reads inconsistently. We typically start at the default Iron Bias setting for each mode and adjust based on how much ferrous trash the site contains.

The Equinox 900 has three lighting features for low-light and night detecting: a red backlight for the monochrome LCD display (adjustable to High, Med, Low, or Off), a red backlit keypad (High, Low, or Off), and a built-in control pod flashlight. The red backlighting preserves night vision better than white light, and the flashlight illuminates the ground in front of the coil so you can see where you're digging. Handgrip vibration also provides tactile feedback on target detection when you're running silent mode to avoid disturbing other detectorists or wildlife at night.
