VFLEX Technology

The X-Terra detectors are Minelab's first products to incorporate VFLEX Technology. VFLEX uses state-of-the-art digital and mixed-signal components to enhance standard single frequency technology by replacing most of the analogue circuitry with digital signal processing. The small amount of analogue circuitry still employed has been very carefully designed and calibrated to obtain the outstanding sensitivity, stability, and repeatability required to match the performance of the processing in the digital domain. This radical departure from traditional approaches to metal detector design has been made possible by advances in electronics that power personal digital assistants, cell (mobile) phones, and high-fidelity portable audio.

The VFLEX system involves two main micro-controllers:

This precision means dependable performance and improved immunity to environmental conditions such as ground mineralization, electromagnetic interference, and temperature variations. VFLEX requires accurately constructed and calibrated coils. When the detector starts up, the micro-controllers in the control box and the coil establish communication through a digital data link. Information about the coil is sent to the control box, allowing the detector to identify the attached coil type and set the correct operating parameters. This optimizes performance and makes the detector "future-proof," capable of operating at different frequencies* depending on the coil's electronic properties.

Assembling Your X-Terra

Before assembling your X-Terra, please check that the package includes the following parts:

The diagram shows the assembled detector with parts labeled.

Connecting the Coil

Plug the two rubber washers into the holes on either side of the lower shaft yoke. Slide the yoke into the yoke bracket on top of the coil. Ensure that the spring-loaded pin in the lower shaft is underneath. Insert the plastic bolt through the yoke and the yoke bracket. Fasten with the plastic wing nut provided, being careful not to damage the thread of the bolt by over-tightening. This may need to be loosened to adjust the coil to a comfortable detecting angle.

The coil cable is directly wired into the coil and is not removable. Any attempt to disconnect this cable will void your warranty.

Shaft Assembly

Ensure that the twistlocks of the shafts are loosened by rotating them counterclockwise. Compress the spring-loaded pin in the lower shaft and slide it into the middle shaft until the pin reaches the adjustment holes. The pin will spring out and click into place. Attach the middle shaft to the upper shaft in the same way. Once shafts are assembled, lock them in position by rotating twistlocks clockwise.

The upper shaft assembly location uses two spring-loaded pins to strengthen the joint, one on either side of the shaft.

Armrest Assembly

Place the armrest onto the top of the upper shaft, lining up the central hole in the armrest with a hole in the aluminium shaft. Position the armrest to suit your arm length (see Holding the Detector, pg. 15). Insert the screw up through the stand, upper shaft, and armrest. Tighten the screw, being careful not to overtighten and damage the thread. With the velcro side facing upwards, thread the armrest strap through both slots in the armrest. Ensure the end of the strap will be fastened outwards from your arm.

The X-Terra is designed to be used in both the left and right hand. The diagram shows the velcro strap threaded outwards for the left arm.

Connecting the Control Box

With the LCD facing up, push the control box onto the end of the handle until it fits into place. The LCD window has a protective film affixed to prevent scratching; this may be removed when the detector is fully assembled. The control box may be easily removed for packing and transport in a carry bag.

Disconnecting: Brace the detector firmly against yourself, grasp the control box, and pull it away from the handle.

Coil Cable Assembly

Wind the coil cable around the lower and middle shaft enough times to take up the slack. Use the velcro tabs to keep the coil cable in place against the shaft. It is recommended that one tab is used on the lower shaft close to the coil and the other tab on the middle shaft before the cable reaches across to the control box. Align the coil plug and connect into the socket in the back of the control box, lightly tightening the retaining ring to hold it in place.

Inserting Batteries

The X-Terra uses 4 x AA batteries, which are not included with the detector (see Battery Behaviour, pg. 62). Access the battery compartment via the battery door located on the side of the control box. Slide the battery compartment door upwards with your thumb. Place individual batteries into the compartment as illustrated, ensuring the positive (+) and negative () contacts match the diagram on the control box. Close the battery door by pushing and sliding it downwards.

If the detector does not turn on, check the battery orientation. The detector will not be damaged if the batteries are inserted incorrectly.

Ready for Use

Congratulations! You have successfully assembled your X-Terra. It is now ready for detecting!

Holding the Detector

Thread your arm through the armrest and strap. Grasp the handle of the detector and rest your forearm in the armrest. Your elbow should sit just above the top of the armrest. Lightly tighten the velcro strap and secure it around your arm.

The correct position of the armrest and length of the shaft should allow you to swing the coil in front of your body without any uncomfortable stretching or stooping. Think of the detector as an extension of your arm; it should be straight with your forearm and feel light and comfortable when you pick it up.

Adjusting Shaft Length: Undo the twistlocks, compress the spring pins of the shafts, and move them up or down to suit. Once all shafts are clipped into position, rotate twistlocks clockwise onto the shafts until a firm clamping action is achieved (see Shaft Assembly, pg. 9).

Adjusting Armrest Position: Remove the armrest screw and move the armrest and stand to the desired position (see Armrest Assembly, pg. 10).

Diagrams illustrate correct and too-short shaft lengths.

Sweeping the Coil

Once outside, practice sweeping the coil over the ground in a side-to-side motion while walking forward slowly. Slightly overlap the previous sweep to ensure full ground coverage. An approximate sweep speed is 3 seconds from left to right to left.

It is important to keep the coil close and parallel to the ground at all times. This will increase detection depth and response to small objects. Avoid excessive brushing of the coil on the ground, as this may result in false signals and inaccurate target IDs. A variation in coil height at the end of each swing may also cause confusing sounds and reduce detection depth.

The diagram shows the coil held approximately 1" (2.5cm) parallel to the ground.

Introducing the Control Panel

The control panel features several buttons and the LCD display. The diagram shows the layout of the buttons and their functions.

Keypad Layout

The keypad layout is illustrated, showing the arrangement of the buttons described above.

Turning on the Detector

Press POWER. A short start-up sequence will display, and a tune will be heard. Once on, the detector will be in automatic detection. There will be no numeric reading until a metal object is detected.

Many of the screen pictures in this manual that refer to both models show the X-Terra 50 display only.

LCD Layout

The LCD display shows various information during detection and when accessing settings. The layout includes areas for Target ID, Discrimination Scale, Depth Indicator, and Menu Scale. Icons are displayed to represent different states and settings.

The diagram illustrates the LCD layout, showing the differences between models and the various icons that can appear. Icons are never all shown at the same time. A blank detection display shows no numerical reading until a detection is made.

Detecting Exercise

A good way to become familiar with detecting is to test the detector against a range of metal objects. This exercise is a simple lesson on how the detector interprets metal objects.

Gather a collection of different metal objects, e.g., various coins, gold and silver jewelry, a rusted nail, pull-tab, brass button, and aluminum foil. Take the detector outside, away from known electromagnetic fields or metal objects. Lay objects in a line, sufficiently spaced apart to allow the coil to pass between them.

This test exercise can be used when adjusting the detector's settings (Sensitivity, pg. 44; Volume, pg. 46; Noise Cancel*, pg. 48; Ground Balance*, pg. 50).

Pass the coil across the objects, one at a time, and observe the LCD and the detector's sounds as it detects each object. If you are getting signals from a clear patch of ground, there may be unknown buried metal objects.

Before attempting to pinpoint or recover real targets, it is important to understand how to interpret the audio and visual responses correctly. If the detector is making popping and crackling sounds and displaying numbers when the coil is not over one of the metal objects, try reducing the detector's sensitivity (pg. 44). Once stable, the detector will only sound and display numbers when the coil is passed over a target.

Don't worry if the detector isn't producing a sound over the nail; this is because the detector begins in the default pattern 1, a setting which rejects signals from common junk targets. The X-Terra 50 has additional ways of stabilizing the detector's signals for different environments (Noise Cancel*, pg. 48; Ground Balance*, pg. 50). The X-Terra coil is waterproof (Care of Your X-Terra, pg. 64).

Example Detections

Discrimination Pattern 1: This factory preset pattern rejects ferrous metals and foil, and accepts non-ferrous metals. Patterns can be edited and saved according to detecting preferences.

A non-ferrous coin might show a medium-high tone and 4 icons to indicate depth, approximately 6-8" (15-20cm).

All Metal Pattern: This pattern turns off every discrimination segment, allowing all metals, including ferrous targets, to be detected.

A ferrous nail might show a low tone and 1 icon to indicate depth, approximately 0-2" (0-5cm).

Further understanding of detector basics and detailed detector operation may be obtained from the rest of this manual.

How Detectors Work

Metal detectors work due to the fact that metal is conductive. Metal detectors create an electromagnetic field, which penetrates the ground. When the coil senses a change in this field (caused by a metal object) it sends a signal back to the control box, which then alerts the operator. Metal detectors react to the size, shape, and composition of objects. Typically, the larger the object, the deeper it can be detected.

The X-Terra uses a single frequency (7.5kHz) as the standard operating frequency. This frequency has the ability to penetrate deep into the ground. The frequency of a detector is the number of times a signal is transmitted into the ground and received back, per second (measured in Hertz - Hz).

The diagram shows a simple representation: "BEEP!" indicating a detection.

Target ID

Buried metal objects are referred to as targets. As the coil is passed over a target, it detects its conductivity and displays this as a number. Target Identification (ID) is used to distinguish one type of metal target from another.

Target ID numbers range from -4 to 44 on the X-Terra 30 and -9 to 45 on the X-Terra 50. Negative numbers represent ferrous targets, and positive numbers represent non-ferrous targets. The last detected target ID stays on the display until another target is detected. If the detector passes over a target that it rejects, the display will return to a blank detection screen represented by two dashes (`--`).

The LCD display shows:

Discrimination Scale

In addition to the target ID, targets are also represented as a particular segment on a linear scale at the bottom of the display. Each discrimination segment represents a level of conductivity and ferrous content.

Non-ferrous targets (e.g., gold, silver, copper, bronze) are often higher in conductivity and are represented by the right-hand side segments. Ferrous targets (e.g., nails, scrap metal) generally have low conductivity and are represented by the left-hand side segments.

Desired and undesired targets may appear anywhere along the discrimination scale. For example:

Discrimination segments can be accepted or rejected. Rejected segments appear as black, while accepted segments disappear altogether (allowing signals from metal objects). The combinations of accepted and rejected segments are referred to as patterns.

The X-Terra 30 has 12 segments with Target IDs ranging from -4 up to 44, increasing in steps of 4. The X-Terra 50 has 18 segments with Target IDs ranging from -9 to 45, increasing in steps of 3. More segments allow for more separate target IDs.

The diagrams show example target IDs and segment ranges for both models.

Preset Discrimination Patterns

The X-Terra has preset discrimination patterns customized to detect general desired targets such as coins and jewelry. The X-Terra 30 has an all metal pattern and 1 preset pattern. The X-Terra 50 has an all metal pattern and 2 preset patterns. Patterns 1 and 2 can be edited to create custom discrimination patterns, which are automatically saved.

Patterns are an important part of detecting as they can save you from digging for unwanted targets.

Choosing a Discrimination Pattern

All Metal Pattern: Accepts signals from all types of metals, everything from jewelry to rusty nails (all target IDs). No target signals are rejected.

Pattern 1: Accepts signals from non-ferrous targets (e.g., gold and silver coins). Rejects ferrous objects and non-ferrous aluminum foil. (Specific Target ID ranges are provided for X-Terra 30 and X-Terra 50).

Pattern 2* (X-Terra 50 only): Accepts signals from most non-ferrous targets. Rejects those from ferrous objects and some non-ferrous targets, e.g., aluminum foil and pull tabs. (Specific Target ID ranges are provided).

Toggling Patterns:

Diagrams illustrate the pattern selections on the LCD.

Pinpointing

During normal detection, the X-Terra operates with discrimination patterns. When a target signal is heard, it is an advantage to identify the target's exact position using PINPOINT. Enabling pinpoint instructs the X-Terra to temporarily disengage discrimination and become a non-motion detector. Targets normally discriminated against will emit a signal when beneath the coil.

In pinpoint mode, the detector gives a continuous audio response, unlike the single beep during detection. This continuous response indicates the strength of the target signal directly below the coil. The pinpoint audio response is tone and volume modulated; the difference in tone and volume produced will help in locating the target's position and depth.

The diagram shows how tone and volume change with proximity to the target.

The detector may become noisy if left in pinpoint. If this occurs, return to normal detection before trying pinpoint again.

Procedure:

  1. Once the approximate target location is known, move the coil outside of that area and press PINPOINT (?).
  2. Sweep the coil over the target location. The menu scale segments on the LCD indicate how close the target is to the center of the coil. The detector will produce a high volume only when the center-ring of the coil is directly above the target.
  3. Taking note of the detector's response, reduce the span of each successive pass of the coil until you are confident of the target's location. Make a mental note of the position or, if the ground is sandy, mark a line with your shoe or a digging tool.
  4. Move to one side so that you can pass the coil over the target at a right angle to your initial direction. When the detector sounds, you should know exactly where to dig.

If you have difficulty pinpointing the target, press PINPOINT DETECT again to take the detector out of pinpoint and then return to Step 1.

Recovering the Target

A trowel, knife, or small spade are good tools for recovering targets. Once a target has been located, clear the surface of loose material and check again for a signal. If there is no signal, the target is amongst the surface material. In this case, search the surface material until the target is located. If the target is still in the ground, check again with pinpoint.

The aim when digging is to leave the area of ground exactly as you found it. Using a sharp tool, cut a neat portion of grass or soil and place it on a plastic sheet. This prevents the material being scattered around and allows the hole to be refilled.

Important Note: Ask for permission before searching on private property.

A long, blunt-tipped screwdriver is a good tool for soft ground. Probe the soil to find the exact location of a target; if it is very shallow, simply prise it out.

Check the hole for the target. If it 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. Be sure not to wear rings, bracelets, or a watch, which will produce a signal. Repeat this procedure until the target is located. Ensure that no other targets remain, then refill the hole. All soil and portions of grass on the plastic sheet should be returned to the hole 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 you leave an area of ground as it was found. Try to take all rubbish.

Detailed Detector Operation

This section covers advanced operation and settings for the X-Terra detectors.

LCD Icons

The LCD display uses various icons to convey information:

Sounds

The X-Terra uses various audio cues:

Sensitivity

Sensitivity is the detector's level of response to a target and its environment. It has a wide adjustment range. Setting the correct sensitivity level is important for your detecting conditions. Real targets are interpreted as distinct beeps, while interference or false targets are interpreted as crackling or popping noises. High sensitivity may detect tiny ferrous junk targets and can be affected by soil minerals or signals from other electrical appliances.

Experimentation may be required for different areas. For beginners, start with a low setting and increase progressively. Decreasing sensitivity can help stabilize the detector, reduce false signals and interference, and assist in differentiating between soil mineralization and metal targets. Choose the highest stable sensitivity setting for optimum performance.

For beach detecting, a setting below 10 may be required. In high trash areas, a setting below 6 may be required, especially for shallow coins (X-Terra 50 settings).

The highest sensitivity settings (7-10 for X-Terra 30, 15-20 for X-Terra 50) should only be used in the quietest, most stable conditions.

Diagrams show the sensitivity adjustment on the LCD.

Volume

Volume is the level of sound the detector gives when a target is detected. The volume control limits the potential loudness of target signals. The X-Terra has proportional target signal volume: a distant target starts softly, and the volume increases rapidly as you get closer, up to the maximum set level.

The sound produced in pinpoint or ground balance will vary in volume and tone depending on signal strength. This volume range is proportional to the maximum volume setting.

The X-Terra can save separate settings for speaker and headphone volume, switching automatically when headphones are connected (Accessory Headphones, pg. 66). Set speaker volume without headphones, and headphone volume with them connected. Use the exercise (pg. 22) to confirm settings.

When the detector battery is low (indicated by the ? icon), the speaker volume limit will be reduced to save power and extend detecting time. You may override this, but risk earlier shutdown.

Diagrams show the volume adjustment on the LCD.

Noise Cancel*

The detector may become noisy or erratic due to electrical interference from powerlines, equipment, or other detectors nearby. Noise Cancel* allows you to change the noise cancel channel to experience less interference. Three channels are available: -1, 0, and 1, indicated on the menu scale.

It is best to choose a channel with the coil in the detection (horizontal) position, as interference received vertically may differ. The coil should be held in the air and away from large targets when changing channels.

There is no loss in depth or sensitivity if the noise cancel channel is changed.

Noise cancel channels: -1, 0, 1 (Factory preset noise cancel channel: 0)

Diagrams show the noise cancel adjustment on the LCD.

Ground Balance*

The X-Terra 30 has a fixed ground balance adequate for most soils. The X-Terra 50 has an adjustable ground balance to compensate for false signals caused by ground mineralization. When unbalanced, the detector may register false detections (displayed as -9 in all metal or two dashes in preset patterns), causing good targets to be displayed briefly with clipped sound.

Ground balancing reduces false detections and enables good targets to be displayed and heard correctly. Ground balance settings affect both normal detection and pinpoint operation.

If difficulty arises in an area, try reducing sensitivity (pg. 44).

Ground balance range: 0-20 (Factory preset: 6)

When detecting on the beach, adjusting ground balance may not yield significant improvements; try adjusting sensitivity and altering patterns for best results.

Highly mineralized soil may produce false signals and distract from real targets. Mineralized ground and 'hot rocks' may register as -9 when detecting in all metal, especially at high sensitivity settings and with an unbalanced detector.

Procedure for Manual Ground Balance (X-Terra 50):

  1. Using the detector in All Metal mode, find a clear area of ground without targets.
  2. Hold the coil parallel and 4" (10 cm) above the ground. Select GROUND BALANCE*. A constant hum, the ground balance tone, will sound when the coil is held steady.
  3. Continuously lower and raise the coil towards and away from the ground, listening to the ground balance tone. Try to lower the coil as close to the ground as possible without touching it.
  4. Adjust the ground balance using the + and - buttons, listening for minimum volume, which occurs during the transition from low to high.
  5. If the tone is low, increase the ground balance setting using +. If the tone is high, decrease the setting using -. The menu scale and numeric ID will indicate the chosen setting.
  6. If ground balance is between two numbers, select the lowest number.

Diagrams illustrate the ground balance adjustment and tone/volume changes.

Editing Discrimination Patterns

The detector's preset discrimination patterns can be edited to create custom patterns. The All Metal pattern cannot be edited.

Method 1 - To reject a specific target ID using an actual target:

  1. In detection mode, a discrimination segment will flash, indicating its position on the discrimination scale and the target's ID number will appear on the LCD.
  2. Press ACCEPT REJECT (✔️/❌) to reject that target ID. The discrimination segment and an 'X' icon will appear, and the target ID number will disappear to indicate the rejected ID.
  3. Check that the target ID has been rejected by detecting again; there should be no audio response from that target ID.

Method 2 - To reject a specific target ID using + / - buttons:

  1. In detection mode, use + and - to scroll through and select the ID you want to modify. The flashing segment and the target ID numbers will indicate the selected ID.
  2. Press ACCEPT REJECT (✔️/❌) to either accept or reject that ID. The discriminated segment and 'X' icon will appear (become shaded) if rejected. The segment and 'X' icon will disappear if accepted.

ACCEPT REJECT toggles between accepting and rejecting targets.

Diagrams illustrate these editing processes.

Factory Presets

Erasing Custom Patterns: Custom patterns are saved when the X-Terra is switched off. To erase custom patterns and return to preset patterns:

  1. Turn the detector off.
  2. While pressing and holding PATTERNS, turn the detector back on by pressing POWER once.
  3. During the start-up sequence, release PATTERNS.
  4. After the start-up sequence, the message PE ([Patterns Erased]) will appear for 3 seconds to indicate that the current patterns have been erased and returned to the preset patterns.

Returning to Preset Menu Values: The settings Sensitivity, Volume, Noise Cancel*, and Ground Balance* are saved when the X-Terra is switched off. To return to the preset menu values:

  1. Turn the detector off.
  2. While pressing and holding MENU SELECT, turn the detector back on by pressing POWER once.
  3. During the start-up sequence, release MENU SELECT.
  4. After the start-up sequence, the message FP ([Factory Preset]) will appear for 3 seconds to indicate that Sensitivity, Volume, Noise Cancel*, and Ground Balance* have returned to the preset values.

Diagrams illustrate the button presses for these reset functions.

Reference Information

This section provides supplementary information for operating and maintaining your X-Terra.

Error Messages

The detector will indicate errors with specific messages and sounds:

Once all errors are resolved, the detector will begin operation with a blank detection screen.

Diagrams show the LCD display for each error condition.

Battery Behaviour

The X-Terra is capable of using different types of AA batteries:

Rechargeable Lithium Ion batteries will give a combined voltage above 8V and therefore cannot be used with the X-Terra. Overvoltage will cause the battery icon to flash and the detector to shut down.

Battery Icon States:

When the detector battery is low, the speaker volume limit will be reduced to save battery power and extend detecting time. The headphone volume is not affected. The use of headphones will increase battery life.

Diagrams illustrate battery discharge over time for Alkaline and NiMH/NiCad batteries.

Care of your X-Terra

The X-Terra is a high-quality electronic instrument, finely engineered and packaged in a durable housing. Taking proper care of your X-Terra is common sense.

Accessories

Skid Plate: A skid plate comes standard with the detector. If it wears out from excessive sweeping along the ground, accessory skid plates are available for purchase.

Environmental Cover: Protects the control box from environmental conditions such as rain and dirt.

Accessory Coils: Come in different types (Double D and Concentric), sizes, and frequencies*. These coils are suitable for different ground conditions and specific targets. To attach an accessory coil, turn the detector off using POWER, and follow the steps for Coil Cable Assembly (pg. 12) and Connecting the Coil (pg. 8) in reverse order to disconnect the old coil, then repeat the steps in the correct order to connect the new coil. Turn the detector on using POWER.

Headphones: Have many advantages, including blocking external noise (wind, traffic) for closer listening to target signals, minimizing disturbance to others, and extending battery life. Ensure headphone volume does not reach an extremely loud level to avoid hearing damage. Use headphones with a 1/4" (6.35mm) jack. Open the rubber headphone cover on the left side of the control box and plug the jack into the socket. When headphones are connected, the headphones icon (?) will appear on the LCD. Keep the rubber cover closed when not using headphones to protect electronics from moisture and dust.
