MDS‑10 Detector Specification �����������64

MDS‑10 Overview

The MDS‑10® combines unique Metal Detection (MD) and Ground Penetrating

Radar (GPR) technologies to provide superior results in the detection of buried metal and non‑metal explosive device components including:

• Wires

• Improvised explosive devices

• Landmines

• Cluster munitions

• Unexploded ordnance

Dual Sensor Technology

The MDS‑10 combines Minelab’s patented

Simultaneous Multi‑Frequency Digital technology and Chemring’s proven Ultra Wideband

Impulse Radar to detect all conductive and non‑conductive targets of interest in varied soil conditions and operating environments.

Metal Detection (MD) and Ground Penetrating

Radar (GPR) sensors can operate independently or simultaneously, providing selectable visual, vibration, and audio feedback to the Operator.

The MD Sensor detects metal and some conductive non‑metal objects (such as carbon rod IED switch components).

The GPR Sensor is capable of detecting non‑metal and metal objects appearing as sub‑surface ground anomalies.

Rugged and Compact

Constructed from impact resistant materials, the

MDS‑10 is designed to survive in many operating environments.

Each detector is supplied in an impact resistant hard transit case that contains the MDS‑10, a tough nylon carry bag, and accessories.

MDS‑10 is compact and lightweight to reduce fatigue during extended operation.

Ease of Use

The User Interface features a versatile colour LCD screen and is designed for intuitive operation and minimising Operator training requirements.

Safe

It is not possible to accidentally disable both sensors or all detection feedback modes.

It includes a Built‑in Test (BIT) capability to monitor and confirm detector functionality.

Additional Features

• Continuous real‑time display of MD and GPR detections with the ability to pause graphical imagery for scrutiny of potential targets.

• Adjustable MD and GPR Sensitivity with Volume control.

• Target Classification for MD Sensor targets

(Conductivity, Ferrous/Non‑ferrous, Carbon Rod indications).

• Fully enclosed and protected cables.

• Screen is viewable in bright sunlight.

• Tactical Mode for night operations.

• Waterproof to 3m/10'.

• Compatible with Night Vision Imaging Systems

System Overview | 9

Operating Modes Overview

The MDS‑10 has three main operating modes; Dual Sensor Mode, MD Mode, and GPR Mode.

Dual Sensor Mode (Default)

In Dual Sensor Mode, both MD and GPR Sensors are operational and provide detection feedback to the operator.

Operation in Dual Sensor Mode is achieved by

enabling both the MD (page 29) and GPR

(page 36) Sensors, and is the default operating

mode.

To differentiate between sensors, there are different audio tone responses for each sensor.

Each sensor has separate colour coded Target

Indicator LEDs for visual response (MD LEDs are red, GPR LEDs are yellow). However, the vibration response is indistinguishable between sensors.

MD Mode

In MD Mode, the MD Sensor is enabled, and the

GPR Sensor is disabled.

The following MD Sensor Modes are available in both MD Mode and Dual Sensor Mode:

MD Detection Mode

– this mode is optimised for maximum detection performance and is the

primary MD Sensor Mode (page 30)

Pinpoint Mode

– this mode provides a static detection response that is useful for localising

targets (page 30)

Interrogation Mode

– this mode provides additional information regarding probable

target characteristics (page 30)

The following additional MD functions are also available in both MD Mode and Dual Sensor

Mode:

MD Ground Balance

– a calibration function that reduces MD false detection responses

caused by ground mineralisation (page 31)

MD Noise Cancel

– this function minimises

MD interference from nearby electronic

sources (page 34)

MD Sensitivity

– this function allows the user

to set MD Sensitivity (page 35)

GPR Mode

In GPR Mode, the GPR sensor is enabled and the

MD Sensor is disabled.

The following GPR Sensor functions are available:

GPR Skyshot

– a calibration function that removes the GPR’s own ‘self signature’ from the

target response (page 37)

GPR Sensitivity

– this function allows the user

to set GPR Sensitivity (page 39)

GPR Advanced Settings

– these functions allow the user to set GPR Start/Stop Gates, and

the GPR Detection Threshold (page 40)

10 | System Overview

MD and GPR received signal strength.

Target Indicator LEDs show a weak received signal

Target Indicator LEDs show a strong received signal

The LED indicators provide both visible light and non‑visible IR indication for both sensors, allowing

Operators to use NVIS when necessary.

Audio Feedback

Audio feedback should be the primary feedback used by Operators as it is capable of conveying more detection signal information to an Operator than visual or vibration feedback. Skilled

Operators can typically achieve higher detection performance using audio feedback than visual or vibration feedback alone.

The MD and GPR Sensors have distinctly different audio tones for easy differentiation. Audio is able to be emitted from both the speaker located on the back of the User Interface, and/or through an earset.

For information on use of the supplied earset and

other audio accessories, read Detector Audio on page 27.

Vibration Feedback

Vibration feedback is provided by a vibration motor located in the handle of the detector.

The intensity and duration of vibration feedback is proportional to that displayed by the Target

Indicator LEDs.

Tactical Mode

Tactical Mode is provided as a quick means of configuring the detector settings for use in tactical deployment situations.

When Tactical Mode is enabled, the user interface does the following:

• Disables speaker audio (earset audio will remain On if an earset is connected)

• Sets the LCD and Target Indicator LEDs to

Night Vision Mode, i.e. LCD is Off and the Target

Indicator LEDs are only visible using NVIS.

• Enables vibration feedback.

Enabling Tactical Mode

1.

Short‑press both the Trigger button and Setup button simultaneously to enable.

To disable Tactical Mode, press both the Trigger button and Setup button simultaneously again.

MD Sensor Overview

The MD Sensor detects metal (conductive) objects.

Enabling the MD Sensor

The MD Sensor is enabled and disabled by long‑pressing the MD button.

All MD related functions are colour coded red for quick recognition.

When the MD Sensor is enabled, the MD Sensor

Modes can be accessed. These Sensor Modes are unavailable when the MD Sensor is disabled.

The 3 available MD Sensor modes are:

• Detection Mode (page 30)

• Pinpoint Mode (page 30, page 50)

• Interrogation Mode (page 30, page 51)

Detect Screen with the MD Sensor enabled.

MD Trace

When the MD Sensor is enabled, the red MD

Trace at the bottom of the Detect Screen is displayed. The MD Trace visually displays the responses from metallic targets.

Data scrolls in real‑time across the screen from right to left. The image represents 4 seconds of data, with the left representing data from 4 seconds ago. The most recent data is displayed on the right.

The size of peaks on the MD Trace is proportional to received target signal strength, similar to the Target Indicator LEDs.

Weak target detections will product small variations in the MD Trace. Strong target detections will produce large peaks in the MD

Trace.

Small or deep metallic targets

Large or shallow metallic targets

MD Overview | 29

MD Sensor Modes

Detection Mode (Default)

Detection Mode is optimised for maximum detection performance, and is the default MD

Sensor Mode used for initial searching of new ground to detect targets.

In Detection Mode, the detection signal is dynamically processed, meaning the Sensor Head must be moving relative to the target (e.g. using a normal sweeping search technique) in order to register a detection response.

In Detection Mode, audio target responses have pitch and volume that is proportional to received target signal strength. Strong targets will be loud/ high‑pitched and weak targets will be quieter/ low‑pitched.

Detection Mode is optimised for target detection and is more sensitive than Interrogation Mode or Pinpoint Mode. Therefore, very small targets detected in Detection Mode may not be detected when using Interrogation Mode or Pinpoint

Mode. If this occurs, use Detection Mode to pinpoint a detected target, rather than using

Pinpoint Mode.

Pinpoint Mode

Pinpoint Mode provides a static response such that target feedback will be heard even if the

Sensor Head is stationary with respect to the target. This mode is useful for locating targets.

To enable Pinpoint Mode, press and hold the

Trigger button.

When the Trigger button is released, the MD will return to Detection Mode.

Pinpoint Mode is used to map a detected metal target to discover its size and shape. For detailed information on mapping a target using Pinpoint

Mode, see page 50.

30 | MD Overview

Pinpoint Mode can also be used to locate the centre of a target. For detailed information on locating the centre of a target using Pinpoint

Mode, read page 50.

Interrogation Mode

Interrogation Mode provides additional information regarding the probable characteristics of a target based on its response to the magnetic field transmitted by the MD, including:

• Apparent target conductivity.

• Whether the target is ferrous or non‑ferrous.

• Whether the target is potentially a carbon rod switch component.

In Interrogation Mode, audio responses consist of a single 'beep' tone where the pitch corresponds to the characteristics of the detected target.

• Ferrous targets sound very low‑pitched.

• Carbon Rod targets sound very high‑pitched.

• Non‑Ferrous targets will have a mid‑range pitch response where the pitch is proportional to the conductivity of the target.

To enable/disable Interrogation Mode, press and release the Trigger button.

For detailed Interrogation Mode operation

information, see page 51.

MD Sensor Overload

When operating any of the MD Modes

(Detection/ Pinpoint/ Interrogation), very large metal objects close to the Sensor Head may overload the detector’s electronics.

If this occurs, the Coil Overload icon will flash on the LCD, and the

Overload Alarm will repeat until the Sensor Head is moved away from the source of the overload.

Overloading is not harmful to the electronics of the detector.

MD Ground Balance

MD Ground Balance reduces noise caused by ground mineralisation, allowing targets to be detected more clearly.

The MDS‑10 is capable of detecting metallic objects in all ground conditions. During the

Ground Balance procedure, the detector learns and adapts to the ground characteristics to reduce ground noise and false alarms due to mineralised (magnetic/lateritic) soils.

Frequent Ground Balancing will ensure maximum detection performance.

Ground Balance must be performed every time the detector is powered On.

It is recommended that Ground Balance be repeated:

• When ground conditions change.

• When it is suspected that the detector is responding to the ground.

The MDS‑10 uses a fixed Ground Balance system that will only change during a user‑initiated

Ground Balance procedure. The MDS‑10 will not automatically adjust to different ground during detecting.

MD Sensor Calibration

The MD Sensor calibration occurs for approximately 5 seconds after the MDS‑10 is powered On.

During MD start‑up calibration, the first MD Target

Indicator LED will flash. When the LED stops flashing and remains static on, a Ground Balance can be initiated.

If Ground Balance is attempted before the start‑ up MD calibration is complete (i.e. first MD Target

Indicator LED is flashing), an invalid button press tone will sound.

MD Overview | 31

MD Ground Balance Procedure

1.

Ensure this procedure is carried out on ground that contains no metal targets, and is representative of the ground in the intended search area.

3.

Sweep the coil left and right across the metal target free ground, maintaining a sweep height of 25–50mm (1–2").

25–50mm (1–2")

2.

From the Detect Screen, with the MD Sensor enabled, short‑press the Ground Balance button to initiate the Ground Balance process.

The Ground Balance button

A flashing Ground Balance icon will appear on the LCD, indicating that Ground Balance is in progress.

Ground Balance can be cancelled by pressing the Ground Balance button again.

4.

After eight seconds, there will be a confirmation tone/vibration, the flashing

Ground Balance icon will disappear, and the detector will return to Detection Mode.

5.

Sweep the coil back over the metal free ground checking for any ground noise or false alarms. Repeat Ground Balance if required.

Successfully completing Ground Balance may allow the use of a higher MD Sensitivity level due to reductions in ground noise and false alarms.

32 | MD Overview

Ground Balance Mode

The MDS‑10 has two Ground Balance Modes:

IED Mode

(Default)

Conventional Mode

IED Mode

(Default)

The IED (Improvised Explosive Device)

Mode for the MD Sensor is the default and recommended mode for most detecting operations.

IED Mode is sensitive to high frequency IED‑like targets such as wires, carbon rods, and very fine metal parts. IED Mode can also be more susceptible to naturally conductive elements in the environment, such as charcoal fragments or salt (e.g. wet beach sand adjacent to seawater). In such scenarios Conventional Mode can be used.

Conventional Mode

The Conventional Mode behaves more like a conventional mine detector such as the Minelab F3. It is less sensitive to high frequency objects such as wires, carbon rods and charcoal. It maintains a high sensitivity to metal targets typically detectable by conventional metal detector technologies.

Conventional Mode can be used for beach locations.

Selecting an Appropriate Ground

Balance Mode

Use of IED Mode is recommended except:

• When detecting on wet sand at a seawater beach or other salt environment,

• When detecting in an area known to be contaminated with charcoal fragments, fine wire or metal fragments, or

• If, after performing a Noise Cancel and Ground

Balance, the MD Sensor still gives a high number of false alarms with an MD Sensitivity setting of 4 or lower in IED Mode.

In these scenarios, Conventional Mode may give better performance.

WARNING:

Conventional Mode is less sensitive to certain IED threats including wires and carbon rod switch components. The Operator must always take the threat environment into account when deciding on a suitable Ground Balance

Mode.

MD Noise Cancel

MD Noise Cancel adjusts the MD Sensor to reduce electrical interference.

Detectors may become noisy due to electrical interference from power lines, electrical equipment, or other detectors operating nearby.

The detector interprets this interference as inconsistent, erratic detections, even when the detector is held stationary.

3.

The Noise Cancel icon and progress bar will be shown on the LCD. A tone and/or vibration indicates that Noise Cancel is in progress.

Do not use the detector whilst Noise Cancel is in progress.

MD Noise Cancel Procedure

1.

Hold the Sensor Head stationary and away from the ground and metal targets.

After 25 seconds, there will be an audio tone when the Noise Cancel is complete. The progress bar will reach 100%, and the icon and progress bar will disappear.

Nearby Detectors Procedure

If operating in close proximity with other detectors and there is interference, the following procedure should be followed:

1.

Enable the MD Sensor on all detectors.

2.

Perform Noise Cancel on each detector, one at a time to ensure that each detector selects a different operating frequency.

3.

Perform Ground Balance on each detector after Noise Cancel, before commencing detecting.

MD Sensitivity

MD Sensitivity should be adjusted as needed to reduce false alarms arising from difficult grounds.

The MD Sensitivity setting has a range from 1 (low) to

10 (high) with a default setting of 6

.

To avoid missing targets, always set the sensitivity to the highest setting which does not give excessive false signals when the Sensor Head is swept over ground which is free of targets.

This setting will depend on the ground being searched, and how well the detector has ground balanced to the soil.

36 | GPR Overview

GPR Skyshot

Skyshot is a calibration to remove the GPR's own radar signature from the

GPR system for clearer imagery and optimum detection performance.

The GPR Sensor requires a Skyshot procedure before each use, and cannot be operated and no

GPR Imagery (page 43) will be generated until

this is performed.

In addition, a Skyshot should be repeated:

• If the Skyshot icon is flashing on the LCD.

• After each hour of continuous operation, indicated by the small flashing Skyshot icon.

• After the Sensor Head angle or rotation or shaft length has been adjusted.

• If the GPR target audio feedback becomes noisy or;

• If horizontal 'bands' or other visual indications can be seen in the GPR image with the Sensor

Head raised away from the ground.

GPR Sensor Calibration

The GPR Sensor calibration occurs for approximately 15 seconds after the MDS‑10 is powered On. During GPR start‑up calibration, the first GPR Target Indicator LED will flash. When the LED stops flashing and remains static on, a

Skyshot can be initiated.

If Skyshot is attempted before the start‑up

GPR calibration is complete (i.e. first GPR Target

Indicator LED is flashing), an invalid button press tone will sound.

GPR Overview | 37

GPR Skyshot Procedure

1.

Ensure that the GPR Sensor is enabled, then raise the Sensor Head high up in the air, away from all objects.

4.

The GPR Image should appear clean without any objects visible. If the GPR image is degraded or horizontal bands are present

(when the detector is still raised), repeat the above steps until a clean GPR image is achieved.

2.

Short‑press the Skyshot button to initiate the

Skyshot process..

Skyshot is complete (approximately 2–3 seconds).

Bad Skyshot: horizontal bands are present in the GPR

Imagery when the detector is still raised.

38 | GPR Overview

2–3s

GPR Sensitivity

GPR Sensitivity should be adjusted as needed to reduce false target signals in more difficult grounds.

The GPR Sensitivity setting has a range from 1 (low) to 10 (high) with a default setting of 6

.

Increasing sensitivity will increase the likelihood that targets (and clutter) will cause audio feedback and overlay highlights on the display.

This is done according to a specific profile that increases with depth. Deeper targets will be amplified more relative to shallow targets as sensitivity is increased.

To avoid missing targets, always set the sensitivity to the highest setting which does not give excessive false signals (audio, visual, or vibration) when the Sensor Head is swung over ground that is free of targets. This setting will depend on the ground being searched and other conditions, such as soil moisture content.

The GPR Sensitivity level is displayed visually in the LCD Status Bar at all times when the GPR

Sensor is enabled.

It is the responsibility of the Operator to test and ensure that the chosen GPR Sensitivity setting is safe and correct before beginning operations.

The GPR Test Target or FFE (Free From Metal) target should be buried and then detected to confirm

the suitability of GPR Sensitivity settings. (See GPR Test Target Procedure on page 23).

GPR Overview | 39

Advanced GPR Settings

The advanced GPR settings allow fine tuning of the GPR detection capability.

GPR Start/Stop Gates

The GPR Start/Stop Gate Function allows the

Operator to mask detections from layers of soil near the surface, and at the bottom of the detectable depth range.

This helps to eliminate unwanted false alarms from rough or uneven soil surfaces, and shallow or very deep layers of clutter in the soil.

The Start and Stop Gates are adjusted independently.

The Start Gate has a range from 0 to –100 with a default setting of 0.

The Start Gate can be set to suppress detections from targets and clutter that appears above the

Start Gate Marker. This reduces false alarms due to rough or uneven ground, or clutter layers near the surface, such as grass or layers of leaf matter. The grey GPR imagery will still be displayed, but audio,

LED and vibration responses and red overlay highlights will be suppressed for targets or clutter above the Start Gate marker. Note that this setting will also suppress detection responses from flush or shallow buried targets, and should only be used when necessary.

The Stop Gate has a range from –100 to 0, with a default setting of –100.

The Stop Gate can be set to suppress detections from targets and clutter that appear below the

Stop Gate marker. This may be useful to suppress responses from deep clutter layers. The Grey GPR imagery will still be displayed, but audio, LED and vibration feedback, and red display overlay markings will be suppressed below the Stop Gate marker.

Setting the Start/Stop Gates

1.

Ensure that the GPR Sensor is enabled, then long‑press the Skyshot button.

The Skyshot button

The Start Gate icon and numerical value will be displayed. Markers will flash on the left and right of the LCD, indicating which Gate is currently being adjusted.

2.

Use the Plus (+) and Minus (–) buttons to increase or decrease the Gate position. The markers will move correspondingly.

Repeat as necessary while sweeping the

Sensor Head over the type of ground to be searched until false alarms no longer occur.

3.

Short‑press the Skyshot button to proceed to the Stop Gate adjustment.

4.

Repeat step 2 to adjust the Stop Gate.

The Gate positions cannot be overlapped, so a value lower than the Start Gate value must be selected.

The GPR Detection Threshold setting has a range from 0 to 100 with a default setting of 30

.

A higher GPR Detection Threshold setting will result in more detection feedback for weaker targets, but also more false alarms due to ground clutter.

A lower GPR Detection Threshold setting will reduce false detections due to ground clutter, but will also result in less detection feedback for weaker targets.

Note that GPR Detection Threshold works similarly to GPR Sensitivity, however it applies the same

GPR Imagery Overview

Understanding GPR Imagery is a learned skill. Below are the basic fundamentals of GPR imagery interpretation.

The MDS‑10 has a unique visual representation of subsurface imagery. This allows the Operator to distinguish anomalies visually, as well as audibly. Visual interpretation is based on soil composition, size, shape and density of the anomaly.

Basics of GPR Imagery

The MDS‑10 displays GPR raw data which shows an image of buried objects and sub surface structures.

Data scrolls in real‑time across the screen from right to left (4). The image represents 4 seconds of data, with the left representing data from 4 seconds ago. The most recent data is displayed on the right.

Shallow buried objects (close to Sensor Head) will be displayed near the top of the image and deep buried objects are displayed lower in the image.

Deep buried object detected.

Detection Sweep‑Speed Effect

The Operator can sweep the detector slowly or quickly, up to approximately 1 metre (3‑feet) per second.

Sweeping the Sensor Head quickly will compress the visual image on the display. Sweeping the Sensor

Head slowly will elongate the visual representation of the anomaly.

Large target detection with a fast sweep-speed. The imagery becomes compressed across the time period.

GPR Overview | 45

Search Technique

Using the correct search technique is crucial for optimum detecting.

Search Speed

The detector should be swept with a smooth even motion at a speed between 0.5 to 1 metre/sec (1.5' to 3'/ sec). If the detector is swept too fast or too slow small or deep targets may be missed.

Search Overlap

It is standard operating procedure to use a half coil overlap when sweeping, to ensure full ground coverage.

Search Height

To minimise false alarms, ensure that the Sensor

Head is swept as parallel to the ground as possible, at a height of approximately 25–50mm (1–2").

Sweeping the Sensor Head closer than 25–50mm

(1–2") is recommended when only the MD Sensor is operating.

The GPR Sensor should optimally be operated no closer than 25mm (1") above the ground to avoid ground coupling. Ground coupling is the interaction between the GPR transmitter and the receiver, which results in clutter and noise in the

GPR Imagery.

46 | Operating Procedures

Locating the Target

Target location techniques narrow down the exact location of a target.

Mapping the Target

Mapping a detected target is an important procedure that will allow the Operator to immediately gain an impression of the approximate location, size, and type (e.g. MD or

GPR) of the target.

Mapping the target also confirms that the target is not in close proximity to a second target.

This procedure is effective for mapping targets with both GPR and MD enabled (in Detection

Mode). For the MD, there are additional techniques that can be used to locate metal

targets more accurately. See MD Edge Mapping

Procedure on page 49, and MD Pinpointing

Procedure on page 50.

Target Mapping Procedure

1.

Maintaining the standard sweeping technique, sweep the Sensor Head over and beyond the target in an attempt to find clear ground.

With each sweep, the MD Trace (or GPR

Imagery) will display the strongest signal when the Sensor Head is in close proximity to the target.

2.

Form a mental image of the approximate bounds of the target.

Once the Operator has obtained an approximate idea of the size, relative depth, and metallic content of the target, greater target accuracy can be achieved.

Use the MD Edge Mapping (page 49) and/or

MD Pinpointing (page 50) procedures to more

accurately locate the target.

Operating Procedures | 47

MD Search Tips

Sensor Head Orientation

Always approach targets to be located/mapped/ pinpointed with the long sides of the Sensor Head.

Never use the back and front of the Sensor Head to approach a target, as the target may not be detected, or may be inaccurately located.

Pinpoint Mode Target Feedback

Activating Pinpoint Mode alters the manner in which the metal detector operates.

Detection Mode gives a dynamic response i.e. the Sensor Head must be moving over a target in order to detect it.

When Pinpoint Mode is selected, it changes to a 'static' response. This means that the detector will give target feedback when the Sensor Head is stationary/moving very slowly over a target.

This assists in finely pinpointing the location of a target.

Sensor Head Null Zone

If a target contains metal, the MD audio response increases to the maximum pitch when the Sensor

Head is immediately adjacent to the target centre

(on both sides), with a ‘null zone’ precisely centred over the target.

Null zone

Peak sensitivity zones

Sweeping over a target with MD Pinpoint Mode enabled will produce a

‘double‑beep’ response due to a characteristic of the MD figure‑8 receive coil.

The coil has a precise null down the length of the centre of the coil

(and corresponding peak sensitivity areas either side).

MD Detection Mode can produce a 'triple‑beep' response because it is a dynamic mode that is motion‑dependent.

MD Pinpoint Mode is a static mode resulting in a 'double‑beep' which reflects the sensitivity pattern of the MD coil.

48 | Operating Procedures

MD Edge Mapping Procedure

The MD edge mapping procedure uses Pinpoint

Mode to identify the outer edges of a metal target when only the MD Sensor is enabled.

Note:

Pinpoint Mode is slightly less sensitive than Detection Mode, and may not work well for extremely weak target detections. In these instances, use Detection Mode to map the target

(steps 2 to 5).

Do not select Pinpoint Mode when the Sensor Head is above the target.

This may result in the target being masked.

1.

Move the Sensor Head away from the target and enable Pinpoint Mode by pressing and holding the Trigger button.

2.

Move the Sensor Head to approach the target area from a variety of angles.

Do not use the short sides of the Sensor Head

(see Sensor Head Null Zone on page 48).

The Pinpoint icon will appear on the LCD, and the audio responses will change.

As the Sensor Head approaches the target, the

Target indicators will indicate that the target is in close proximity.

3.

When there is an audio response, mentally mark the position on the ground.

4.

Move the coil away, and approach the target from another angle.

5.

This process continues until a clear mental picture of the target size and shape is achieved. The Operator will also be confident that the target is contained in the mapped area.

Once the target has been mapped, Pinpoint the

centre of the target (page 50).

Mapping Multiple Targets

The Operator may find multiple objects of interest in close proximity but may want to locate them separately.

Use the normal target location procedures to determine the locations of multiple targets. An irregular shape may emerge, allowing the centres of individual targets to be pinpointed within it.

Operating Procedures | 49

MD Pinpointing Procedure

After the target edges have been mapped, the

MD Pinpointing procedure is carried out to precisely determine the centre of the target.

If the target contains metal, and the metal in the target is sufficiently small, the area mapped will also be small, therefore it is easier to identify the centre of the target.

Note:

Pinpoint Mode is slightly less sensitive than Detection Mode, and may not work well for extremely weak target detections. In these instances, use Detection Mode to find the centre of the target (steps 2 to 5).

Do not select Pinpoint Mode when the Sensor Head is above the target.

This may result in the target being masked.

1.

Move the Sensor Head away from the mapped target and enable Pinpoint Mode by pressing and holding the Trigger button.

2.

Sweep the coil over the target.

If the target contains metal, the MD audio response will increase to the maximum pitch when the sensor heard is immediately adjacent to the target centre.

3.

When a response is heard, mentally mark the centreline.

4.

Repeat the process with the detector oriented at 90° to the first position. The intersection of the two lines will indicate the target location.

The Pinpoint icon will appear on the LCD, and the audio responses will change.

5.

To disable Pinpoint Mode and return to

Detection Mode, release the Trigger button.

Once the MD target has been Pinpointed, it can

be Interrogated (page 51).

50 | Operating Procedures

MD Interrogation Mode

Interrogation Mode provides information regarding characteristics and composition of a target.

When using the detector in Dual Sensor Mode, the separate MD and GPR signals may be used to differentiate targets of different types.

For example, a large metallic object will generate a high target response from both the MD and

GPR, while a large non‑metallic object would generate a high target response from the GPR but little to no response from the MD.

Conversely, a very small metallic target may not generate a response from the GPR, but still generate a response from the MD.

Audio feedback will change; Interrogation

Mode audio will vary in tone corresponding to

the target composition (see page 30).

A Target ID will also be displayed on the LCD corresponding to the tone emitted.

3.

Pass the coil over the target to be interrogated, while paying attention to target feedback and reviewing the Target ID.

Interrogation Mode Audio

MD Interrogation Mode will provide an audio tone related to the targets ferrous content and conductivity. The detection tone in Interrogation

Mode is not related to the target size and proximity as it is in MD Detection Mode.

Interrogation Mode Procedure

1.

Ensure that the MD Sensor is enabled.

Interrogation Mode cannot be enabled when operating only the GPR Sensor.

2.

Press and release the Trigger button once to enable Interrogation Mode.

The Target Identification (ID) Field will be

displayed (see page 52 for detailed Target ID

information).

4.

Press and release the Trigger button to return to Detection Mode.

Note:

Interrogation Mode will provide a specific tone for a target. However, the tone is not unique and other targets may produce the same type of tone. In different types of soil, the same target may give a different tone when interrogated.

Operating Procedures | 51

MD Target ID

MD Target ID represents the apparent conductivity and likely composition of a target.

Target IDs are based on the characteristics of a detected target's response to the magnetic field applied by the MD.

The MD Target ID is an identification displayed in the Target ID Field on the LCD when MD

Interrogation Mode is enabled, consisting of a single digit and letter.

The conductivity of a detected target is represented as a dimensionless number from

0 (low conductivity) to 9 (high conductivity).

The number is also represented visually on the

Conductivity Bar.

The likely material type of a detected target is represented as a letter.

In general, the stronger the target signal strength, the more accurate the Target ID.

Ferrous Targets

If a detected target is ferrous, the letter 'F' is displayed beside the number (0 to 9) inside the Target ID Field, and the Ferrous icon appears on the right.

Ferrous targets give a very low‑pitched beep tone in Interrogation Mode.

Non‑Ferrous Targets

If a detected target is non‑ferrous, a number (0 to

9) is displayed in the Target ID Field, but no letter will be displayed.

Non‑ferrous targets give a medium to high‑ pitched beep tone in MD Interrogation Mode, depending on their conductivity (higher pitch corresponds to higher conductivity).

Low Conductivity Targets

If a detected target has very low conductivity, the letter 'C' is displayed beside the number inside the Target ID Field, and the Carbon Rod icon appears on the left.

Low conductivity targets usually have a Target ID of 0 or 1, and have characteristics consistent with carbon rods or small wires. These can be found in particular types of IED threats.

Low conductivity targets give a distinctive very high‑pitched beep tone in MD Interrogation

Mode.

Troubleshooting, Safety, and Maintenance | 57

Error Codes

In the event of a hardware fault, the MDS‑10 will display an Error Code. Try the recommended actions first, before reporting the detector as faulty.

The MDS‑10 has a Built‑in Test (BIT) capability for identifying faults that can occur in the detector.

In the event of a BIT failure, the error icon will be displayed on the LCD. If audio is enabled, there will also be a distinctive audio alarm tune.

Error Codes are divided into three types:

• System Error Codes

• MD Error Codes

• GPR Error Codes

An Error Code corresponding to the fault type will usually be displayed on the Setup Screen.

Errors will normally remain active until the detector is powered Off then back On.

Operator corrective actions are limited steps required to reset the detector to determine whether the fault is a transient condition, or if it is persistent. Units with persistent faults will need to be returned an Authorised Service Centre for investigation and repair.

System, MD, and GPR errors have three levels of severity: advisory, critical and fatal.

Critical Errors

Critical errors are conditions affecting detector performance.

Critical errors are indicated by a continuous alarm in all enabled Feedback settings (audio, visual and vibrate). The MD and GPR Target Indicator LEDs will display the Error sequence (alternating between the four left LEDs and the four right LEDs).

For critical MD and GPR errors, the error icon appears on either the left or the right of the

Detect Screen to indicate the affected Sensor.

Critical MD and GPR errors can be silenced by disabling the affected sensor, allowing the user to continue detecting with the functional Sensor.

Critical System Errors are indicated by the error icon and a code on the Detect Screen. They can only be reset by powering Off the detector.

Error icons on the Detect Screen. It appears on the left for critical MD errors, and on the right for critical GPR errors.

Safety Advice and Maintenance

The MDS‑10 is safe to transport, store and operate when handled with the due care. Safety hazards applicable to this equipment are identified below.

Hazard

Emission of non‑ ionising radiation.

Electromagnetic interference

Internal voltages

Precaution

The GPR and MD Sensors in the Sensor Head emit very low power magnetic fields and

Radio Frequency (RF) energy. The radiated energy from both Sensors is significantly lower than that emitted by a mobile telephone and is safe to human health.

Operators do not need to follow any specific safety precautions to mitigate hazards to human health posed by the emission of non‑ionising radiation from the equipment.

While interference with communications equipment is unlikely, consideration should be given to potential effects on other equipment in proximity.

Voltages potentially capable of causing electric shock are present on some internal conductors in both the GPR and MD Sensors.

Inspect the MDS‑10 shafts, Sensor Head enclosure, Control Box enclosure, and Battery for evidence of damaged or exposed cables or electrical conductors prior to use. Do not use the equipment if there is any evidence of damaged or exposed cables or electrical conductors.

Speaker/earset audio volume

Exposure to excessively high audio volumes with any audio generating equipment can cause discomfort and possible temporary and permanent hearing loss. The maximum output volume via the earset and speaker for the detector are limited to be within safe levels for peak sound pressure level exposure. Operators should also use the Volume control to ensure the audio volume is not set above comfortable levels.

Ensure the Volume control is not set above comfortable levels during operation.

Air transport safety requirements

The MDS‑10 should not be powered On while being transported by air, and all applicable safety regulations must be followed in relation to carriage of electronic equipment, including lithium‑ion batteries on aircraft.

Follow all applicable safety regulations including the directions from aircrew when transporting MDS‑10 equipment by air.

Ergonomic hazards

The MDS‑10 is a lightweight Dual Sensor detector, designed to minimise the risk of fatigue, strain, or other musculoskeletal injury to Operators. Operators using the equipment should always observe correct detecting posture and technique.

Exposed fibres from damaged carbon fibre shafts

Inspect the detector shafts prior to use. Do not allow damaged or abraded carbon fibre shaft sections to come into contact with skin.

The MDS‑10 middle and upper shafts are made from carbon fibre material. Damaged or abraded carbon fibre materials can expose fibres which can cause cuts and abrasions to skin, and ingress under the skin with potentially toxic effects.

Pinch‑points

The MDS‑10 has been designed to avoid the presence of pinch‑points, but is a compact, collapsible piece of equipment that requires moderate care when extending or collapsing. Keep fingers clear of sliding and rotating mechanisms including shaft camlocks, and around the base of the folding handle in the vicinity of the earset connector, when extending or collapsing the detector.

62 | Troubleshooting, Safety, and Maintenance

Hazard Precaution

Lithium‑ion battery safety and advice

The MDS‑10 comes with a high capacity, rechargeable lithium‑ion battery. Both the battery and MDS‑10 provide internal protection circuitry to ensure safe operation of the battery. All local regulations related to the operation, handling, storage and transportation of lithium‑ion batteries must be observed, including the following:

• Inspect lithium‑ion batteries before use. Do not use batteries with the equipment if damaged in any way.

• Do not short circuit or reverse polarity the lithium‑ion batteries. Fire or explosion may result.

• When fitting batteries to the detector, ensure the O‑ring on the battery around the contacts is fitted to prevent moisture, sand or dust fouling the battery contacts.

• Do not use or store the lithium‑ion batteries outside the specified operating temperature range for the Detector.

• Do not recharge the lithium‑ion batteries with anything other than the battery charger supplied with the equipment.

• Do not allow the lithium‑ion battery internal cells to fully discharge.

(Note: batteries may be safely operated until the MDS-10 shuts down due to low battery, without fully discharging the battery internal cells.)

• Ensure batteries have at least a partial charge if prolonged storage is anticipated.

• Do not expose lithium‑ion batteries to fire, explosion, solvents or corrosives or other hazardous substances.

• Do not incinerate, puncture, crush, or otherwise damage or misuse lithium‑ion batteries.

• Do not transport lithium‑ion batteries by aircraft except where explicitly authorised under applicable air transport regulations. Observe all applicable regulations when transporting the equipment.

• Dispose of lithium‑ion Batteries only in accordance with all applicable local and national environmental regulations.

• Recharge the battery after long periods of non‑use to maximise battery life

(approximately every 6 months)

Battery charger safety

The charger has been constructed from quality materials and is designed to be maintenance‑free.

• Do not attempt to charge batteries other than the Harris 12041‑2400 series batteries supplied with the MDS‑10 using the supplied charger. Attempting to charge a battery with the wrong chemistry can result in an incomplete charge, battery damage, fire or explosion.

• Do not substitute the AC power supply supplied with battery charger for any other

AC power supply.

• Do not attempt to charge batteries outside of the recommended charging temperature range of 0°C to +40°C (+32°F to +104°F).

• Do not block the ventilation slots.

• Keep away from moisture. Clean only with a dry or slightly damp lint‑free cloth.

• Do not remove cover. The charger has no internal user‑serviceable parts.
