contents Congratulations on purchasing your x-terra 705! Metal detecting is a fascinating and rewarding activity enjoyed by people all over the world. By getting to know your X-Terra 705 you can become one of the many who find valuable coins, relics, gold and jewellery on a regular basis. The X-Terra 705 is a high-precision instrument incorporating Minelab’s proven single frequency technology, VFLEX.
2 3 how detectors work Metal detectors create an electromagnetic field, which penetrates the ground. Metal objects cause a change to this field because they are conductive. The detector senses this change and sends a signal back to the control box, alerting the operator. Metal detectors can determine the size, shape and composition of metallic objects beneath the coil. Typically, the larger the object, the easier it is to detect.
5 assembling your x-terra 705 List of Parts Connecting the Coil Before assembling your X-Terra 705 please check that the package includes these parts: Plug the two rubber washers into the holes on either side of the lower shaft yoke. Coil Slide the yoke into the yoke bracket on top of the coil. Ensure that the spring loaded pin in the lower shaft is pointing downwards. Skidplate (fitted to coil) Lower shaft Insert the plastic bolt through the yoke and the yoke bracket.
6 7 Assembling your x-terra 705 Armrest Assembly Coil Cable Assembly Place the armrest onto the top of the upper shaft, lining up the central hole in the armrest with one of the holes in the aluminium shaft. Position the armrest to suit your arm length (Holding the Detector, p. 14). Wind the coil cable around the lower and middle shaft enough times to take up the slack. Insert the screw up through the stand, upper shaft and armrest.

Headphones This icon indicates that headphones are connected and that the headphone Volume and Threshold have been selected (Volume, p. 36). 11 Target ID Stability This icon indicates that Target ID Stability has been selected (Target ID Stability, p. 20). Backlight This icon indicates when the Backlight is On.
12 turning the detector on It is recommended to only turn the detector on, when outdoors, away from sources of electromagnetic disturbance. There are many metallic objects inside a house (e.g. nails in the floor, reinforcing in the walls) that might overload the electronics of the detector. There may also be interference from TV sets and other household appliances. In this environment the detector may perform erratically, giving numerous false signals.
14 holding the detector To hold 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 armrest and length of shaft should allow you to swing the coil in front of your body without any uncomfortable stretching or stooping.
16 a simple detecting exercise detector audio 17 Buried metal objects are referred to as targets. Before attempting to pinpoint or recover real targets, it is important to understand how to interpret the audio and visual signals of the detector. Don’t worry if the detector is not 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, including ferrous targets.
18 coin & treasure mode prospecting mode 19 Coin & Treasure Mode is used for detecting valuable objects including old and modern coins, jewellery and artefacts. Undesired objects such as pull-tabs and bottle caps may be rejected. This mode can be used in a variety of environments such as parks and salt water beaches. Prospecting Mode is used to find metal such as gold nuggets and relics in highly mineralised, ‘difficult’ areas. Targets are identified by audio only.
20 target id Buried metal objects are referred to as targets. Target signals contain ferrous and conductivity information. pattern discrimination scale 21 Target ID The numeric identifier of a particular metal object underneath the ground. As the coil is passed over a target, the detector digitally processes the target signal 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 –8 to 48.
22 PRESET DISCRIMINATION PATTERNS The X-Terra 705 has an All Metal Pattern, four preset Discrimination Patterns and Iron Mask. The combinations of accepted and rejected segments are referred to as Discrimination Patterns. The X-Terra 705 has preset Discrimination Patterns that have been customised to detect general desired targets, such as coins and jewellery. Patterns 1, 2, 3 and 4 can be edited by you to create your own custom Discrimination Patterns.
24 choosing a discrimination pattern Pattern Discrimination In Coin & Treasure Mode use Patterns to toggle between Pattern 1, Pattern 2, Pattern 3 and Pattern 4. All Metal Shortcut The X-Terra 705 has an All Metal shortcut available in both modes. In Coin & Treasure Mode, press All Metal to toggle between the selected Pattern and All Metal. editing a discrimination pattern 25 The Preset Discrimination Patterns may be edited to create custom patterns.
26 pinpointing Pinpoint Sizing coil In Pinpoint, the detectors 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 locate the position and depth of the target.
28 menu operation adjusting menu settings 29 The X-Terra 705 operates in two display states – Detection and Settings. Detection (display state) Settings (display state) In Coin & Treasure Mode, the Target ID, discrimination segments and depth automatically translate target signals. The last detected Target ID stays on the display until another is detected. If the detector passes over a target that it rejects, the display will return to a detection screen represented by two dashes.
30 sensitivity The X-Terra 705 is highly sensitive and has a wide Sensitivity adjustment range. It is important to set the correct Sensitivity level for your detecting conditions. Sensitivity is the detector’s level of response to a target and its environment. Real targets are indicated by distinct beeps and should stop if the coil is held stationary. Interference or false targets are interpreted as crackling or popping sounds and generally continue when the coil is held stationary.
32 noise cancel The detector may become noisy or erratic due to electrical interference from powerlines, electrical equipment or other detectors operating close by. This interference is interpreted as a crackling or popping noise. Noise Cancel allows you to change the noise cancel channel so that you experience less interference. Five channels are available, represented by the numbers -2, -1, 0, 1, 2, and are also indicated on the menu scale.
34 threshold Threshold is the constant background sound produced by the detector to help distinguish between desirable and undesirable targets. When a rejected target is detected, the Threshold sound ‘blanks’ (becomes silent) to indicate that a rejected target is underneath the coil. Normal Signal Threshold adjusting threshold 35 The Threshold volume should be set to the preferred level.
36 volume adjusting volume 37 Volume is the level of sound emitted by the detector when a target is detected. The Volume control limits the maximum volume of target signals. When the detector battery is low (indicated by the low battery icon) the speaker volume limit will be automatically reduced. This saves battery power and extends detecting time. The sound produced by a distant target starts softly.
38 tones adjusting tones 39 Target Tones The number of Target Tones may be selected from the Tones menu. There are five different options listed in the table below. Press Menu/Select Tones . and choose Adjusting Target Tones in Coin & Treasure Mode Use the + and – to select either 1, 2, 3, 4, or Multiple Target Tones (99). Press Pinpoint/Detect detection.
40 ground balance The X-Terra 705 is capable of operating in two different types of grounds, magnetic (e.g. inland parks and goldfields) and conductive (wet areas of salt water beaches). Ground mineralisation may cause false target signals in all environments. Ground Balancing the detector reduces these ground signals and enables good targets to be displayed and/or heard correctly.
42 adjusting ground balance Auto Using the detector in All Metal, find a clear area of ground without any targets. Hold the coil parallel and 4” (10 cm) above the ground. Select Ground Balance . A constant hum known as the Ground Balance tone will sound when the coil is held steady. adjusting ground balance 43 Press Mode to activate Automatic Ground Balance, and begin to continuously lower and raise the coil over the ground.
44 Tracking ground balance offset This setting is recommended for experienced users. battery behaviour 45 The X-Terra 705 is capable of using different types of AA batteries: Tracking GB Offset allows you to set the Tracking Ground Balance slightly positive or negative allowing a performance advantage under certain conditions. 1.5 V Alkaline For example, this can be useful in mineralised ground with hot rocks.
46 factory presets 47 Menu Factory Preset Mode Factory Preset Mode Specific, General and Mode Dependent settings are all saved when the X-Terra 705 is switched off (p. 12). The X-Terra 705 allows the user to reset settings for the current detect mode only. To return to all of the preset menu values: Select the detect mode which needs to be reset. Turn the detector off. Turn the detector off. While pressing and holding Menu/Select turn the detector back on by pressing Power once.
48 coil identification error messages 49 Coil Unplugged The X-Terra 705 is capable of operating at three different transmission frequencies set by VFLEX compatible coils. The coil is not connected to the detector. Concentric Standard (7.5kHz) This frequency is most suitable for general detecting for most ground conditions. These coils have a label with the letter M on them.
50 sounds recovering the target 51 Threshold Positive Acknowledgement This is the background ‘buzz’ given by the detector to help distinguish between accepted and rejected targets. The detector emits a short beep for every valid key press. Blanking The detector emits a low double beep to indicate an invalid keypress. When a rejected target is detected, the Threshold sound ‘blanks’ (becomes silent) to indicate that a rejected target is underneath the coil.
52 accessories 53 The use of headphones while detecting, has many advantages. They block out external noise such as wind and traffic, allowing you to listen more closely to target signals. Headphones also minimise disturbance to other people in the area and they extend battery life. The X-Terra 705 is able to save separate settings for both the speaker volume and headphone volume, switching from one to the other as soon as the headphones are connected.
