Terminology

The following terms are used throughout the manual and are standard terminology among detectorists.

ELIMINATION

Reference to a metal being "eliminated" means that the detector will not emit a tone, nor display a Target-ID, when a metal object passes through the searchcoil's detection field.

DISCRIMINATION

When the detector emits different tones for different types of metals, and "eliminates" certain metals, this is referred to as the detector "discriminating" among different types of metals. Discrimination is an important feature of professional metal detectors, allowing the user to ignore trash and otherwise undesirable objects.

RELIC

A relic is an object of interest due to its age or association with the past. Many relics are made of iron, but can also be made of bronze or precious metals.

IRON

Iron is a common, low-grade metal that is undesirable in certain metal detecting applications. Examples include old cans, pipes, bolts, and nails. Sometimes, desired targets, like property markers, are made of iron. Valuable relics can also be composed of iron, such as cannon balls, old armaments, and parts of old structures and vehicles.

FERROUS

Metals which are made of, or contain, iron.

PINPOINTING

Pinpointing is the process of finding the exact location of a buried object. Long-buried metals can appear similar to the surrounding soil, making them hard to isolate.

V.C.O. (Voltage Controlled Oscillator)

The V.C.O. audio method causes both audio pitch and volume to rise as signal strength increases, improving the user's ability to interpret a target's size and depth. Very weak signals (small or deeply buried objects) have the faintest volume and lowest pitch. Larger objects or those closer to the searchcoil produce higher volume and pitch.

GROUND BALANCE

Ground Balancing is the detector's ability to ignore or "see through" the earth's naturally occurring minerals, sounding a tone only when a metal object is detected. This detector incorporates proprietary circuitry to eliminate false signals from severe ground conditions.

Pre-Assembly

Unpack your detector to find the following contents:

• 1. Control Housing
• 2. Armrest Assembly with Screw and Lock-Nut
• 3. Searchcoil
• 4. Middle Stem
• 5. Lower Stem with Bolt & Knurled Knob attached
• 6. S-Rod with 2 Screws (attached with tape)

Tool Required: #1 Phillips Screwdriver

Assembly Steps:

1. Remove the Screw from the Armrest.
2. Slide the Armrest over the end of the S-Rod.
3. Attach with Screw and Lock-Nut.
4. Attach Control Housing with 2 screws; install the back screw first.
5. Note: The Hand-grip fits under the Control Housing. Peel back Hand-grip to expose the front hole.

Assembly

Caution: Forcing the Middle Stem with the Cam Lock raised may form a burr on the camlock. If this happens, remove the burr with a knife to allow insertion.

1. Position S-Rod upright.
2. Rotate the Locking Collar fully in the counterclockwise direction.
3. Insert your finger inside the tube and ensure the Internal Cam Lock is flush with the inside of the tube.
4. Insert the Middle Stem into the S-Rod, with the Silver Button pointed upward.
5. Rotate the Middle Stem until the Silver Button locates in the hole.
6. Twist the Locking Collar fully in the clockwise direction until it locks.
7. Repeat this process on the Lower Stem.
8. Using the Bolt and Knurled Knob, attach the Searchcoil to the Lower Stem.
9. Adjust the Lower Stem to a length that allows a comfortable upright posture, with your arm relaxed at your side, and the Searchcoil parallel to the ground in front of you.
10. Wind the Cable securely around the Stems.
11. Insert the plug into the matching connector on the back of the detector body. Ensure the key-way and pins line up correctly.
12. Tighten both Locking Collars.

*Note: Very tall users can purchase the optional Extended Lower Stem (TUBE5X) for extended reach.

Batteries

The detector requires a single 9-volt ALKALINE battery (battery not included). Do not use ordinary Zinc Carbon batteries or "Heavy Duty" batteries.

Rechargeable batteries can also be used. Nickel Metal Hydride rechargeable batteries are recommended.

The battery compartment is located on the back side of the housing. Slide the battery door to the side and remove it to expose the compartment. Push down firmly on the bottom of the battery for easy removal.

Battery Life

Expect 20 to 25 hours of life from a 9-volt alkaline battery. Rechargeable batteries provide about 8 hours of usage per charge.

Battery Indicator

The battery icon on the right of the display has three vertical segments and an outline segment. Battery voltage is indicated as follows:

• 3 vertical segments illuminated: 8.1 volts or more
• 2 vertical segments illuminated: 7.1 to 8.0 volts
• 1 vertical segment illuminated: 6.5 to 7.0 volts
• No vertical segments illuminated: 6.2 to 6.4 volts
• Outline Flashing: 6.1 volts or less

Speaker Volume and Battery Charge

Speaker volume may drop as the battery level decreases. With the outline flashing, low speaker volume will be very apparent.

Armrest Strap (Optional Accessory)

The strap is available for purchase separately. Some users prefer it when swinging the detector vigorously to hold it secure against the arm. The detector can also be used without the strap without compromising balance or stability.

Quick-Start Demonstration

V. Select Discrimination Setting

Press the [Menu Button] twice to activate the DISC selection.

1. While sweeping the Nail back-and-forth, press the [Plus Button] to increase the DISC setting.
2. Continue to press the [Plus Button] to increase the DISC setting. Notice that the Nail is eliminated from detection when the DISC setting equals its Target-ID.

Caution: Passing the nail at differing angles will yield different ID numbers.

VI. Repeat Step V

Repeat Step V while waving the Gold Ring, and then also while waving the Silver Coin.

The Basics of Metal Detecting

This metal detector is intended for locating buried metal objects. When searching for metals, underground or on the surface, you face challenges and have objectives such as:

1. Ignoring signals caused by ground minerals.
2. Ignoring signals caused by unwanted metal objects, like nails.
3. Identifying a buried metal object before digging it up.
4. Estimating the size and depth of objects to facilitate digging.
5. Eliminating the effects of electromagnetic interference from other electronic devices.

Your metal detector is designed with these factors in mind.

1. Ground Minerals

All soils contain minerals, and signals from these minerals can interfere with signals from metal objects. Soil types vary greatly in mineral content. The Eurotek has a preset ground elimination setting, requiring no user adjustments.

2. Trash

When searching for coins, you may want to ignore items like aluminum foil and nails. You can observe the Target-ID value of buried objects, listen to the sounds, and decide whether to dig. Alternatively, you can use the DISCRIMINATION feature to eliminate unwanted metals from detection.

3. Identifying Buried Objects

Metal objects are identified by a 2-digit number on the display screen, with 99 points of resolution. This number indicates the relative electrical conductivity of the target; higher numbers signify more conductive targets. Iron objects typically display lower numbers, while silver coins usually display the highest numbers.

4. Size and Depth of Buried Objects

The 3-digit bar graph indicates the relative depth of a buried metal object. It can also represent the relative size of objects or their distance from the searchcoil. More bars illuminated indicate a deeper or larger object.

5. EMI (Electromagnetic Interference)

The searchcoil produces a magnetic field and detects changes caused by metal objects. This field is also susceptible to electromagnetic energy from other electronic devices like cell phones, power lines, microwave ovens, and TVs. This EMI can cause the detector to beep when no metal is present or beep erratically.

The SENSITIVITY control reduces the strength of this magnetic field, lessening susceptibility to EMI. While operating at maximum strength is desirable, EMI may make it impossible. If you experience erratic behavior or "false" signals, reduce sensitivity.

Headphone Jack

This detector has a 1/4" headphone jack compatible with any stereo headphone having a 1/4" plug. When headphones are connected, the speaker volume is disabled.

Using Headphones

Using headphones facilitates detection of the weakest signals and extends battery life. They also allow clearer hearing of subtle sound changes, especially in noisy locations. For safety, do not use headphones near traffic or other dangers. Use with headphone cables shorter than three meters.

Operation and Controls

Powering Up

Press the [Power Button]. The detector powers on. A "[Target Detected Symbol]" appears momentarily, indicating Discrimination Mode. All targets are detected; motion is required. Default sensitivity is 7 (scale 1-10), and default discrimination is 0 (scale 0-79).

How to Work the Controls

Press the [Menu Button] to select the menu item you want to adjust. Press the [Plus Button] or [Minus Button] to change the setting of the active menu item. The active menu item is highlighted on the top of the display.

Menu Selections

Operational Overview

Press the [Menu Button] to activate the menu system: SENS or DISC. The SENS menu appears first. Successive presses of the [Menu Button] toggle between SENS and DISC. With a menu selection visible, press [Plus Button] or [Minus Button] to change settings. When the desired setting is reached (indicated by the 2-digit value), no further action is needed. The menu icon will time out after 4 seconds, programming the last displayed setting. Alternatively, press [Menu Button] again before timing out to advance to the next selection. During operation, pressing [Menu Button] recalls the last menu selection.

While the MENU display is active, the LCD will not respond to targets, but the audio system will continue to respond to targets or overload signals.

1. SENS (Sensitivity)

Press the [Menu Button] to illuminate the SENS menu icon. Use the [Plus Button] and [Minus Button] to increase or decrease sensitivity while SENS is highlighted. Maximum sensitivity is 10; minimum is 1.

If the detector beeps erratically or when no metal objects are present, reduce the sensitivity.

The searchcoil produces a magnetic field and detects changes caused by metal objects. This field is susceptible to electromagnetic energy from other electronic devices (cell phones, power lines, etc.), which can cause interference and erratic beeping.

How Deep Will It Go?

The Eurotek Metal Detector can detect a coin-sized object up to approximately 20 cm (8") at maximum sensitivity. Large metal objects can be detected to a depth of over a meter. Detectability is directly related to object size: larger objects are detected deeper. Target identification accuracy also depends on distance; targets at the fringe of detection will have less accurate Target-IDs than closer targets.

2. DISC (Discrimination)

The DISC control allows the user to eliminate a range of targets. The user selects a 2-digit number; targets with an ID less than or equal to this setting will not be detected. Be aware that irregular targets or those on the fringe of the detectable range may produce varying Target-ID numbers, potentially leading to inconsistent elimination.

Press the [Menu Button] to illuminate the DISC menu icon. Each press of the [Plus Button] or [Minus Button] changes the DISC setting by one. Press-and-hold [Plus Button] or [Minus Button] to rapidly advance or reduce the setting.

Examples of coins and their typical Target-IDs:

• Bulgarian 10 stotinkas, 1999
• Bulgarian 50 stotinkas, 1999-2007
• Peter I, 1705, Silver, 0.25 gr.
• Mikhail Fedorovich, 1613-1645
• 50 kopeek Nikolay II, 1896, Silver
• 5 kopeek, Ekaterina II, 1781
• 2 kopeek, Alexander I, 1816
• 10 ct Napoleon III (bronze, France)

Discrimination System

Target Detection

Sweep the detector back-and-forth over the ground. Keep the searchcoil parallel to the ground during sweeps; do not lift it at the ends. Searchcoil motion is required for target detection.

Target-ID: When objects are detected, the detector emits a sound and displays a 2-digit Target-ID (range 1-99). This number represents electrical conductivity; higher numbers indicate more conductive targets. The 2-digit number reflects the last object detected. The Eurotek offers fast target response, enabling detection of objects in close proximity. The Target-ID may change rapidly as you sweep. After three seconds, the Target-ID times out and disappears.

General Target-ID Ranges:

• 1-39: Iron
• 42-48: Foil and small gold nuggets
• 54-57: Gold nuggets, gold rings, or targets containing mostly gold
• 82-83: Copper coins
• 87-89: Clad coins or coins of recent vintage
• 93-99: Larger silver coins

Note: A wide variety of metals exist, and identification is not certain until unearthed. This table is for general reference only. See page 15 for a more complete listing.

2-Tone System

Depending on the metal detected and DISC setting, a buried object will produce one of the following audio responses:

• No sound: Metals eliminated from detection (discriminated-out) via the DISC function.
• V.C.O. (variable pitch and volume): Targets with an ID less than 80.
• High Tone: All targets with an ID of 80 or greater.

The Target-ID and Audio-ID systems operate independently. Inconsistent tones and IDs may occur. For example, a deeply buried target might produce a low tone, but if the signal is too weak for the visual ID system, a reliable Target-ID may not register, even after a tone is emitted.

In-the-Field Techniques

Stance

Stand with your arm extended, maintaining a comfortable, upright posture. Hold the unit so the searchcoil is about 3cm above the ground and parallel to it.

Sweep

In the search position, swing the searchcoil gently side-to-side, slightly overlapping each sweep as you move forward. Keep the searchcoil approximately 3cm above the ground. Raising it during the sweep or at its ends can cause false readings. Move slowly to avoid missing targets.

Desirable objects typically produce a repeatable tone. When discriminating, iron and foil objects are usually eliminated. False signals can result from trashy ground, electrical interference, or large irregular trash objects, which are often broken or non-repeatable.

Examples of coins and their typical Target-IDs:

• 1/4 of Stater, gold, France
• 2 Franc Morlon, aluminum
• Medieval double sol
• 50cent Chambre du Commerce
• Double Tournois, copper
• Roman Nummus, bronze
• Celtic Potin, mixed metal
• Merovingian Triens, gold

Depth Indicator

In Discrimination Mode, a Bar Graph illuminates with the Target-ID for each detected object. The Bar Graph graphically represents the distance from the searchcoil, calibrated for coin-sized objects.

• More bars indicate a deeper object.
• Fewer bars indicate a shallower object.

Scale for coin-sized objects (sensitivity at maximum):

Target-ID Coin Reference

Below are known Target-IDs for some reference coins:

Other Features

Iron Identification

The Eurotek allows users to discriminate iron targets and classify them by size and signal strength. Ferrous objects typically have a Target-ID between 1 and 39. To eliminate all ferrous objects, set DISC = 39.

Pinpointing

Accurate pinpointing requires practice and is best achieved by "X-ing" the target area.

1. Once a buried target is identified by a good tone response, continue sweeping the coil over the target in a narrowing side-to-side pattern.
2. Visually note the spot on the ground where the "beep" occurs as you move the coil slowly side-to-side.
3. Stop the coil directly over this spot.
4. Move the coil straight forward and back a couple of times.
5. Again, visually note the spot where the "beep" occurs.
6. If needed, "X" the target at different angles to "zero in" on the exact spot.

REMEMBER: The detector beeps when the center of the searchcoil passes directly over the buried object. If pinpointing strong signals is difficult, try lifting the coil higher for a weaker, more concise signal. For very weak signals, use short, quick sweeps closer to the ground.

Consider Purchasing a Pinpointer

When unearthing an object, it can be frustrating if it looks like the surrounding soil. A handheld pinpointer is a probe-like device that is poked into the ground for close-up pinpointing, reducing digging time and the size of holes. Teknetics offers a robust and inexpensive pinpointer for this purpose.

Overload Warning

If a metal object or highly magnetic soil is too close to the searchcoil, the detector will "overload." A "[Overload Symbol]" will appear on the screen, accompanied by a rapid, repeating mid-tone warning sound. Overload will not harm the detector but will prevent its function. Raise the searchcoil to a greater distance or move to a different location.

Memory

To store current settings (SENS and DISC):

1. Start with the detector turned ON.
2. Select all desired settings.
3. Press-and-hold the [Menu Button] for 8 seconds.
4. When the two menu selections appear at the top of the screen, release the [Menu Button].

When turned ON, the detector will resume operation with your programmed settings.

Reset

To return all detector settings to factory defaults:

1. Start with the detector turned OFF.
2. Press-and-hold the [Menu Button].
3. Press the [Power Button].
4. Release the [Menu Button].

The 2-digit number displayed is the software revision number.
