Minelab EQUINOX 700 Multi-IQ Waterproof Metal Detector, 11 in Coil

The Minelab EQUINOX 700 is the detector you reach for when the site is more complex than your current machine can handle. Built on Minelab's Multi-IQ simultaneous multi-frequency platform, the EQUINOX 700 transmits across multiple frequencies at once, producing target IDs that hold position as soil mineralization shifts beneath the coil. If you have hunted on a single-frequency VLF and watched coin IDs drift in variable ground, you know exactly what this solves.

What You Gain Stepping Up to the EQUINOX 700

• Target IDs that hold through ground change. Multi-IQ processes the target across multiple simultaneous frequencies. The number on screen reflects a composite conductivity read, not a single-frequency reading skewed by soil moisture or depth.
• Five recovery speed levels for iron-dense sites. At Recovery Speed 3, adjacent targets that blur into a compound response on a slower VLF resolve into distinct signals. Dense iron grids that masked keepers on lower-speed machines start producing readable hits. Speed 1 retains longer signal dwell for isolated deep targets in clean ground.
• Full saltwater access, IP68 to 5 m (16 ft). Beach 2 mode handles the surf zone, compensating for the conductive salt signal that destabilizes most VLF machines past the wet-sand line. No additional waterproofing kit, no housing swap. The whole machine goes in the water.
• 119-segment target ID with adjustable Iron Bias. More segments means finer resolution between adjacent conductivity values. Iron Bias (-1 to 3) gives direct control over how the detector reads ferrous signals adjacent to non-ferrous targets. Dial it per site.
• Tactile ferrous feedback via Handgrip Vibration. When enabled, the handle fires a vibration on ferrous signals independently of audio. On a night hunt or in a noisy environment, that tactile alert changes how fast you call iron before you dig.

The Minelab EQUINOX 900 adds a dedicated Gold mode, 20 and 40 kHz single frequencies, eight recovery speed levels and a second 6 inch coil. Our EQUINOX 700 vs 900 comparison shows which of those you would actually use.

Who the Minelab EQUINOX 700 suits

We like the EQUINOX 700 for someone who wants to search parks, fields, beaches and old home sites with one detector. It gives you most of the practical versatility a serious detectorist needs without the long list of adjustments on Minelab's higher-end machines. What we like most about the 700 is its balance of performance, versatility and manageable complexity.

Field Use and Settings

The Minelab EQUINOX 700's three search mode pairs, Recovery Speed system, and Iron Bias control cover the three environments most detectorists hit regularly. For a broader look at how detector selection maps to season and terrain type, see our year-round metal detecting guide.

Parks and Relic Sites

Targets at hunted-out parks and old homesteads are still there, buried in iron at depth. Park 1 (General and Coins) is the starting profile for coins and general park hunting. Park 2 (Fine Jewelry) accepts all non-ferrous targets and recovers faster, which helps around dense trash. Recovery Speed 2 or 3 keeps adjacent signals distinct. The 5-level depth indicator helps you decide on deep hits before you break ground.

• Mode: Park 1 (General and Coins) or Park 2 (Fine Jewelry)
• Sensitivity: 20 to 23
• Recovery Speed: 2 to 3
• Iron Bias: 0 to 1
• Ground Balance: factory setting, or Auto if the ground requires it; Tracking where mineralization changes as you search

Wet Sand and Surf Zone

Beach 1 handles dry to wet sand; Beach 2 is purpose-built for wading the surf zone and calm shallow freshwater. Beach mode gives residual salt a Target ID of 0, so salt signals sit apart from the non-ferrous range.

• Mode: Beach 1 (dry to wet sand) or Beach 2 (surf zone)
• Sensitivity: 22 to 25
• Recovery Speed: 2
• Iron Bias: 0
• Ground Balance: factory setting; in Beach 2 underwater in saltwater, Tracking may help keep the detector stable

High-Trash Urban Lots

Dense pull-tab and bottle-cap sites are a signal management problem. Recovery Speed 3 and Iron Bias 1 to 2 give the Minelab EQUINOX 700 the snap to separate targets sitting inches apart. All Metal mode is available as a shortcut to the full unfiltered signal before committing to a discrimination setting. Each profile keeps your changed settings until you reset it, so your configuration is there on return visits.

• Mode: Park 2
• Sensitivity: 18 to 22
• Recovery Speed: 3
• Iron Bias: 1 to 2
• Ground Balance: factory setting, or Auto if the ground requires it

Multi-IQ Technology and Separation Controls

Multi-IQ transmits across multiple frequencies simultaneously. The target ID the Minelab EQUINOX 700 displays is a composite conductivity reading, not a single-frequency snapshot. In mineralized ground, Minelab designed Multi-IQ to keep Target IDs steadier than a single frequency can. Four single frequencies (4, 5, 10, and 15 kHz) remain individually selectable when you want precision on a specific conductivity range.

Recovery Speed runs 0 to 4, and Iron Bias (-1 to 3) adjusts how the detector handles ferrous targets next to keepers; see our advice under Settings that matter below.

Settings that matter on the Minelab EQUINOX 700

Recovery Speed: around an old farmhouse full of rusty nails, a faster setting helps separate a coin from the nail next to it. In a clean field, a slower setting can give a better response from some deeper targets. Match it to how crowded the targets are; the fastest setting is not right everywhere.

Iron Bias: in a park full of rusty bottle caps, some caps sound like good coins, and raising Iron Bias can cut down those signals. A higher setting can also affect a good target lying close to iron, so we would start at the factory setting and change it only when the site calls for it.

Target ID: non-ferrous targets read from 1 to 99, against 1 to 40 on the older EQUINOX 800. More numbers still do not identify a buried object perfectly: orientation, depth, corrosion and nearby metal all move the reading, so learn the audio alongside the numbers.

Build, Display, and Audio

The Minelab EQUINOX 700 uses a 3-piece carbon fiber shaft, collapsing to 61 cm (24 inches) and extending to 144 cm (56.7 inches) at 1.27 kg (2.8 lbs) fully assembled. The Monochrome LCD runs a red backlight with a matching red-backlit keypad and Control Pod flashlight for low-light hunting. Battery runtime is approximately 12 hours from the 3.7 V / 5100 mAh internal lithium-ion cell, charged via the magnetic USB connector.

Audio options include the included ML 85 Low Latency Wireless Headphones, the built-in speaker, or wired 3.5 mm headphones. Target tone modes cover 1-tone, 2-tone, 5-tone, All Tones, and Depth tones. Handgrip Vibration fires independently on ferrous signals. A Minelab pinpointer pairs cleanly with the EQUINOX 700 for precise target recovery once a signal is confirmed.

Coil Options

The included EQX 11 inch Double-D Smart Coil is the right starting coil for most sites. The DD design produces a narrow detection blade that keeps targets separated in mineralized ground and stays stable in conditions that challenge concentric coils of the same footprint. Eleven inches gives enough coverage for open parks and fields without becoming difficult to swing in close quarters.

The optional 6 inch Round coil trades coverage for precision: it is the choice for dense iron environments or confined areas where the 11 inch coil creates overlap problems. The optional 15 inch Smart Coil goes the other direction, maximizing ground coverage in open fields and beaches where coverage is the limiting factor.

Where the Minelab EQUINOX 700 works well, and where it does not

In a park laid out more than a century ago, older coins sit deep and close to rusty iron, and Recovery Speed, Iron Bias and the detailed Target IDs let you adapt. A high Target ID does not automatically mean a silver coin, though: a large iron object can sometimes read high.

One detector covers inland sites and the beach. It finds gold jewelry, but it has no Gold mode; for natural gold nuggets, see our gold detectors.

One mistake to avoid with the Minelab EQUINOX 700

Do not reject too many Target ID ranges. Say you are hunting gold jewelry and, tired of digging aluminum, you reject most of the lower-conductivity numbers. Gold rings can read in those same ranges, so aggressive discrimination walks you right past them. We would rather dig some foil than miss a ring.
