Detector Battery
The EQUINOX detector is powered by an internal Lithium-ion battery.
Read 'Battery Charging Recommendations' on page 62 for important safety information.
For instructions on how to charge the WM 08 Wireless Audio Module read page 55. For instructions on how to charge the ML 80 Wireless Headphones read page 57.
Charging the Battery
Going detecting with a fully charged battery is recommended. Typical battery runtime is approximately 12 hours.
EQUINOX Series detectors are supplied with a USB charging cable that features a snap-on magnetic connector.
1. Plug the supplied charging cable into any standard powered USB-A port.
2. Connect the magnetic connector to the charging interface on the rear of the EQUINOX control unit.
The green charge status LED on the top left of the control panel will flash slowly.
3. When the battery is fully charged, the charge status LED will remain on.
Charge Status LED
Charging (flashing)
Battery Status Indicator
The battery status indicator shows the current battery level.
70% –100%
30% – 70%
<30%
<5% (Charging required)
When the battery level is critically low, ‘bF’ will appear on the Target ID Display. The detector will then turn off automatically.
The detector regulates the battery voltage so that its performance remains constant regardless of the charge remaining in the battery.
Battery Maintenance
Lithium-ion battery performance may degrade if unused for long periods of time. Fully charge the battery at least once every 3–4 months to prevent this from occurring.
Even with correct care and maintenance, Lithium-ion battery performance reduces over time with normal use. Therefore the battery may need to be replaced every few years. Replacement batteries can be supplied and installed by an Authorised Service Centre.
Fully charged (on)
The charge time from completely flat to 100% is approximately 4 hours when a high capacity (>1.7A @ 5V) charger is used. Car and wall charging accessories are available for separate purchase.
Any standard USB port compatible with USB battery charging 1.2 (BC1.2) can be used to charge your battery, however charge times may be longer if using lower-power options.
If the detector is turned on during charging, the charge time will be longer.
Disconnecting the Charger
The charging cable can be removed from the charging interface by pulling it sideways, or by pulling it directly backwards.
Operating With a Power Bank
The detector must not be used underwater whilst charging or when connected to a power bank.
You can use your EQUINOX detector whilst plugged into a portable power bank. This means you can continue detecting even if the detector battery is flat.
Connect the power bank to your detector using the supplied EQUINOX USB charging cable, and continue detecting. You can fasten it to the armrest stand via the armrest attachment points.

Detecting Basics
This section contains great information for both new and experienced detectorists.
It explains basic detecting principles and techniques. You can learn how to set up your detector for maximum comfort and ease of use.
How Detectors Work | 14Contents
How Detectors Work
Metal detectors create an electromagnetic field which penetrates the ground. Metal objects cause a change to this field because they conduct electricity. The detector senses this change and sends a signal back to the control unit, alerting the operator.
Basic Principles
Metal detectors work by transmitting an electromagnetic field from the search coil into the ground. Any metal objects (targets) within this electromagnetic field will become energised, creating their own circular electric currents (eddy currents) and transmit an electromagnetic field of their own. The detector’s search coil senses this receive signal and alerts the user by producing a target response. Minelab metal detectors are also capable of discriminating (or differentiating) between different target types and can be set to ignore unwanted targets.
1. Battery (Inside handle)
The battery provides power to the detector.

2

2. Control Unit
This is where the transmit signal is generated and the receive signal is processed and converted into a target response.
3. Search Coil
The detector’s search coil transmits the electromagnetic field into the ground and receives the return electromagnetic field from a target.
4. Transmit Electromagnetic Field (blue)
The transmit (Tx) electromagnetic field energises targets to enable them to be detected.
5. Target
A target is any metal object that can be detected by a metal detector. In this example the detected target is treasure, which is a good (accepted) target.
6. Unwanted Targets
Unwanted targets can be ferrous (iron), such as nails, and can also be non-ferrous, such as pull-tabs. If the metal detector is set to reject unwanted targets then a target response will not be produced for those targets.
7. Receive Electromagnetic Field (yellow)
The receive (Rx) electromagnetic field is generated from energised targets and is received by the search coil.
8. Target Response (green)
When a good (accepted) target is detected the metal detector will produce an audible response, such as a beep or a change in tone, and a visual display of target information will be shown on the screen.

Key Detecting Concepts | 15Contents
Key Detecting Concepts
It is beneficial to understand a few key metal detecting technology principles so that you can select the best settings for different detecting conditions.
For a complete glossary of detecting terms, visit www.minelab.com/knowledge-base/getting-started/glossary-of-terms.
Frequency
The operating frequency of a metal detector is one of the main characteristics that determines how well targets can be detected.
The frequency of a detector is the number of times a signal is transmitted into the ground per second, and is measured in Hertz (Hz). 1000 Hz = 1 kHz.
EQUINOX is unique in that it offers both multi-frequency and single frequency operation. Read 'Frequency' on page 28 for more information.
Find out more about the EQUINOX Multi-IQ technology on the Minelab Treasure Talk blog.
Ground Balance
Ground Balance is a variable setting that improves detection depth by reducing noise in mineralised ground. Mineralised ground may contain salts, e.g. wet beach sand, or fine iron particles, e.g. red soil. These minerals respond to a detector’s transmit field in a similar way that a target does. Due to the much larger mass of the ground compared to a buried target, the effect of mineralisation can easily mask small targets.
EQUINOX has different Detect Modes (Park, Field, Beach, Gold*) to cope with typical ground conditions.
A Ground Balance setting is also available, read 'Ground Balance'
on page 40 for further information.
Detection Depth Factors
The most common question about metal detectors is “How deep do they go?”
The simple answer is “as deep as the diameter of the coil for a coin-sized target”. Therefore detectors with larger coils will detect deeper. However, detection depth also depends upon detector technology and many environmental factors. A more complete answer is usually more complex, and starts with “It depends...” The depth that a metal detector can detect a target depends on a number of factors:
Target Size
Large targets can be detected deeper than small targets.
Target Shape
Circular shapes (e.g. coins and rings) can be detected deeper than long thin shapes (e.g. nails or screws).
Target Orientation
A horizontal coin (e.g. lying flat) can be detected deeper than a vertical coin (e.g. standing on its edge).
Target Composition
Highly conductive metals (e.g. silver) can be detected deeper than less conductive metals (e.g. lead).
Ground Mineralisation
A target in benign (unmineralised) ground can be detected deeper than a target in heavily mineralised ground.
Detecting Technique | 16Contents
Detecting Technique
Correct detecting technique is important to get the most out of your detector. The techniques described will give you the best chance of success.
Holding the Detector
Insert your arm through the armrest and armrest strap. Grasp the handle of the detector and rest your forearm in the armrest.
The correct position of the armrest should allow you to comfortably grip the handle. Your elbow should sit just above the back of the armrest and the detector should feel like an extension of your forearm.
Adjusting the Length of the Shafts
The lower shaft can be adjusted to several set lengths between fully extended and fully retracted. Adjust the lower shaft to the correct length and tighten the twist lock to hold it in place.
A correct shaft length will allow you to swing the coil over the ground without uncomfortably stretching or stooping. If the coil is too far from your body it will be difficult to balance and manoeuvre while detecting. If the coil is too close to your body it may detect your digging tools or any other metal which you are carrying, causing confusing sounds.
Though the coil assembly is rigid and durable, sudden jolts or bangs may cause random signals and inaccurate Target IDs, as well as excessive wear and tear. Careful sweeping will ensure the coil performs to an optimum level at all times.
Sweep Parallel to the Ground
You will obtain the best performance when the coil is swept close and parallel to the ground at all times. This will maximise detection depth and improve the response to small objects. Avoid excessive brushing of the coil on the ground.
Overlap Your Sweep
Practice sweeping the coil over the ground in a side-to-side motion while slowly walking forward at the end of each sweep. Slightly overlap the previous sweep to ensure full ground coverage. An average sweep speed is 2 to 3 seconds from right-to-left-to­right.
Adjusting the Angle of the Coil
1. Loosen the yoke nut and bolt that fastens the lower shaft to the coil. It should be loose enough to allow the coil to be moved for adjustment, but tight enough that the coil can hold its position.
2. While holding the detector in the detecting position, lightly press the coil to the ground until it sits flat/parallel with the ground. The coil should remain parallel when lifted to the sweep height, approximately 25 mm (1-inch) above the ground.
3. Tighten the yoke nut just enough to hold the coil in position.
Sweeping the Coil
EQUINOX Series detectors are motion detectors, meaning that the coil must be moving across the ground in order to detect a target. If the coil is held stationary over a target, it will not be detected. The side-to-side detecting motion is called 'sweeping' or 'swinging', and with practice will become a comfortable and fast way to cover ground.
Sweeping the coil incorrectly can cause you to miss targets or can generate false signals.
Targets
Metal objects are referred to as targets. Targets are comprised of ferrous and non-ferrous metals. Ferrous metals are those containing iron such as steel, nails and some types of coins. Non­ferrous metals are those which are not magnetic, such as gold, silver, copper, bronze and aluminium.
You may wish to find a range of both ferrous and non-ferrous targets.
Examples of Common Targets:
• Desired ferrous target – war artefact
• Undesired ferrous target – iron nail
• Desired non-ferrous target – gold coin
• Undesired non-ferrous target – pull-tab
Detector Sounds | 17Contents
Detector Sounds
The EQUINOX produces a variety of different sounds for target and environmental signals and various detector functions.
Targets
A target signal is the sound produced by the detector when any metal object is detected.
Typically, a ferrous (iron) target gives a low tone response and a non-ferrous target gives a higher tone response that varies according to the conductive properties of the metal (e.g. silver will give a higher tone than aluminium).
Volume and Target Proximity
Large targets and targets close to the ground-surface give louder audio signals.
Signals produced by targets a long way from the coil are quiet, becoming rapidly louder as the coil nears the target.
Deep Targets Shallow Targets
Quiet signal
No signal
The sound produced by the detector in Pinpoint or Ground Balance will vary in volume and pitch depending on the signal strength (from a target or ground mineralisation). This volume range is proportional to the maximum volume setting.
Quiet signal
A large deep target signal will
be the same volume as a small
shallow target signal.
Loud signal
EMI can also be received from other metal detectors operating nearby. Always detect a minimum of 15 metres (45-feet) away from other detectors.
15 m (45")
EQUINOX should not be operated indoors. Metal in the floors and walls, and household appliances will cause significant noise interference.
Ground Noise
Ground interference (or ground noise) may occur when there are high levels of mineralisation in the soil. This can be very common in detecting locations, especially goldfields.
The effects of ground noise can be reduced using Ground Balance
(page 40).
Keypad
The detector will make a sound whenever buttons on the keypad are pressed. A valid button press makes a short high pitched ‘bip’ sound. An invalid button press makes a low pitched beep.
Noise/False Signals
The detector may pick up unwanted noise signals, either through the air or from the ground. These false signals can be reduced by using Noise Cancel or Ground Balance. Turing down Sensitivity will also allow you to operate the detector effectively in difficult (or noisy) locations.
Electrical Noise
Electromagnetic Interference (EMI) may occur near power-lines, phone towers or electric fences. This can cause a detector to perform erratically, causing false signals and inaccurate Target ID.
The effects of electrical noise can be reduced using Noise Cancel
(page 39).
Threshold
The constant background ‘hum’ that can be produced by the detector is called the Threshold. Some users like to hear a threshold tone so that they can hear both target signals and rejected target audio 'blanking'.
When a rejected target is detected, the Threshold ‘blanks’ (becomes silent), indicating that a target is located underneath the coil, but has been rejected by the discrimination pattern.

Simple Detecting Exercise | 18Contents
Simple Detecting Exercise
Before attempting to find real targets, it is important to understand how to interpret the audio and visual signals of the detector.
1. Gather a collection of different metal objects, e.g. various coins, gold and silver jewellery, a nail, a pull-tab, a brass button and aluminium foil.
2. Take the detector outdoors, away from known sources of electromagnetic interferences (EMI) and metal objects.
3. Lay the objects in a line, sufficiently spaced apart to allow the coil to pass between them.
4. Sweep the coil across the test targets one at a time. Observe the Detect Screen and listen to the sounds of the detector as it passes over each object. The Detect Screen and audio response will give you detailed information about the Target ID.
Don’t worry if the detector is not producing a sound over the nail — this is because the detector begins in the default Park Mode Profile 1, which rejects signals from common trash targets, including ferrous targets.
If you are getting signals from a clear patch of ground, there could be buried metal objects. Try finding a different area.
You may like to make a record of the Target IDs for each of your targets.
When you go detecting, always carry a 'test target' with you, e.g. a coin, which is similar to the targets you are looking for.
Bury it at around 4 – 6 inches within your detecting location and adjust your EQUINOX settings until the desired response is heard over the test target.
This way you are guaranteed to detect the same types of targets if they are there. Remember to dig up your test target after you are finished!

A good pinpointing technique helps you to quickly narrow down the location of a buried target, allowing you to determine its exact location before digging.
By combining a good pinpointing technique with the EQUINOX Pinpoint function, you will be able to accurately locate a buried target within an area before you dig.
For additional information on Pinpointing with the help of the Pinpoint function, read 'Pinpoint' on page 36.
It is possible to pinpoint a target successfully without
using Pinpoint, however this requires practice.
Coil Configuration and Pinpointing
The standard EQUINOX Series EQX 11 detector coil has a wire winding configuration know as Double-D.
When pinpointing, it is useful to know that a Double-D coil has two overlapping wire windings in the shape of two D’s. The regions created by the overlapping windings (running from the front centre of the coil to the back) is the most sensitive area and will give the loudest response when a target is directly beneath it.
The line shows the strongest signal zone on the EQX 11 coil. This is also the same for all EQX Double-D accessory coils.
Pinpointing a Target Manually
1. Sweep the coil slowly across the target location keeping the coil parallel to the ground.
2. Locate the centre of the target by listening for the loudest target signal response.
3. Make a mental note of the position, or mark a line on the soil with your shoe or a digging tool.
4. Move to one side so that you can pass the coil over the target at right angles to your initial direction.
5. Line up the target at 90° from the initial direction and repeat the process. The object is located where the two imaginary lines cross.

The benefits of this configuration include lower noise susceptibility (especially in mineralised ground), higher sensitivity, and a very thorough search pattern requiring less sweep overlap.
Double-D coils may produce complex signals from shallow targets. Sometimes three separate signals can be heard for a single target as the coil is swept over it.
The strongest signal
occurs where the Tx and Rx
coil windings overlap.

The intersection of the two lines marks the
exact location of the target.
Target Recovery | 20Contents
Target Recovery
Using the right tools and a good target recovery technique is important to prevent damage to a buried target, which could significantly reduce its value.
Digging Tools
Different detecting locations have different types of ground, so you will need to take the right tools with you. You may wish to use a combination of tools when you dig to speed up the recovery process.
Buy the best quality digging tools you can; Purchase them from a detecting specialist, as tools found in hardware stores can be inadequate for recovering a target and vary widely in quality.
You don’t want to be out on a detecting trip with a broken digging tool!
Park
Field
Beach
Gold*
In Park locations, a digging knife with a serrated edge is great for cutting through turf and fine roots to form a neat plug of earth. A small strong spade is useful for digging bigger holes for deeper targets.
Field locations are often composed of dense clay soil that will clump together. A small strong spade is useful for digging bigger holes for deeper targets.
Typical sandy Beach locations mean targets can be easily recovered with the use of a plastic scoop, or even your hands. A long handled sand scoop is required for recovering submerged targets from the water.
In typical Gold locations, a small pick will help to break open the earth, while a plastic scoop will assist with checking the soil for gold nuggets without damaging them.
Recovering a Target
Be sure not to wear rings, bracelets or a watch, as they will produce a signal when you are recovering targets.
A Minelab PRO-FIND Series pinpointer is another useful tool for quickly narrowing down the location of a buried target within a hole.
1. Once a target has been pinpointed, clear the ground surface of loose material and check the ground again for a signal. If there is no signal, then the target is amongst the surface material. If the target is still in the ground, Pinpoint again.
2. Try to leave the ground exactly as you found it. Using a sharp tool, cut a neat plug, leaving some grass attached on one side like a hinge. Lift the plug out and over. This prevents soil from being scattered and allows the hole to be refilled quickly.
3. Check the hole for the target. If the target is not in the hole, place the detector on the ground with the coil flat. Pick up a handful of soil and pass it over the coil, returning soil to the hole after you have checked it. Repeat this procedure until the target is located.
4. Check that no other targets remain in the hole. Refill the hole with all soil and grass as neatly as possible. Step lightly on the soil to compact it.
Leaving holes or a scarred area may result in action being taken to prevent the use of metal detectors. Please ensure that the area of ground is left as you found it, and remove all rubbish.

Detect Modes
EQUINOX is equally adaptable for all target types and ground conditions… just select your detecting location and go!
Detect Modes are based on common detecting locations, making it easy for anybody to confidently choose the right Mode for their detecting session.
This section explains the differences between the Detect Modes, and includes some great tips to help you master each Mode.
The Detect Mode descriptions in the following section are for typical detecting locations. Some Detect Modes will be useful in locations not represented by the Mode name, icon, or description.
