4. If the device receives noise when you increase the sensitivity setting, you can turn on the Noise Cancellation by long pressing the Frequency & Noise Cancellation button before decreasing the sensitivity setting.
5. You can start detecting!

COMMON AND MODE-BASED SETTINGS

• Certain settings are common to all modes; changes in these settings will take effect in all modes.
• Most of the settings are mode-based and they only affect the mode currently selected; changes made in one mode do not affect the others.
• Common settings and mode-based settings are shown below:

SEARCH MODES

SCORE has 3 search modes designed for different terrains and targets.

Navigating Through Search Modes
You can navigate through the modes easily by using the Right & Left Buttons. The selected mode will be framed.

PARK

• Designed for coin and jewelry hunting in urban areas and parks where there is a lot of modern trash (aluminum foil, pull tabs, bottle caps, etc.) present. There are 3 tones in Park Mode: The device produces a low tone for ferrous targets with 01-10 IDs, a medium tone for gold and non-ferrous metals with IDs 11-41, and a high tone for non-ferrous metals with IDs 41-60 such as silver, brass, and copper.
• This mode is optimized for mid to large coins and jewelry. The default discrimination is set to reject Target IDs up to and including 10 to eliminate ferrous targets.

To avoid targets such as aluminum, you can utilize the Custom Discrimination Pattern. In this pattern, the default discrimination is set to reject Target IDs up to and including 12.

Gold targets may fall between 11-12 IDs. When this pattern is selected, you cannot detect targets with 11-12 IDs.

• Aluminum foil typically generates a Target ID of 11. However, depending on the shape, its ID can go up to 20.
• Both single-frequency and multi-frequency can be used in this mode. Based on the target type, you can choose the frequency you want. Multi-frequency in Park mode will allow for maximum depth and separation. Thus, a slight noise can be experienced.
• Bottle caps are unwanted targets for detectorists and they are mostly detected as non-ferrous targets by metal detectors. Bottle Cap Rejection setting is added to the Park mode by default. This feature enables you to discriminate bottle caps as iron. This feature works in high-frequency only.

FIELD
Recommended for coin and relic hunting in pasture and cropped/plowed fields.

• These fields may contain ferrous trash and coke. To detect coins and relics more easily amongst these trash items, you can use the Custom Discrimination Pattern. In this pattern, the default discrimination is set to reject Target IDs up to and including 12. There are 2 tones in this mode and the tone break point is set to 12.
• Both single-frequency and multi-frequency can be used in this mode. Multi-frequency in Field mode will allow for maximum depth and separation.
• The ID resolution of IDs 11-15 is different in the Park versus the Field mode. You may get a different ID in each mode for targets that fall within this ID range.
• Park and Field modes offer 3 different multi-frequencies Multi-1 (M1), Multi-2 (M2), and Multi-3 (M3). For details, please refer to the Frequency section.
• In Park and Field modes, different algorithms are run in M3 Multi frequency. In trashy sites, M3 Multi frequency in Park mode should be preferred. When a target is isolated underground, the ID will be the same in both modes.
• However, if the target is next to trash such as aluminum foil, Multi 3 in Park mode will generate a more accurate ID for the target.

BEACH

• The salt typically present in beach sand and sea causes the sand and water to be very conductive generating noise and false signals. Single-frequency detectors cannot work in these environments or they underperform. Multi-frequency can minimize this noise allowing for maximum performance in these environments.
• For these reasons, a single frequency cannot be used in the Beach mode. When Beach mode is selected, the device automatically switches to Multi frequency and single frequency cannot be selected.
• There are 2 tones in this mode and the tone break point is set to 10.

Black Sand
Some beaches are covered with black sand which contains natural iron. These types of beaches make metal detection almost impossible. Beach mode senses black sand automatically and displays a warning icon on the top of the screen in the info section. This mode is optimized for use on dry or wet beach sand as well as for underwater use up to 5m. (16ft.).

When this icon disappears, the device resumes its normal operation.

IMPORTANT!
After submerging the device underwater and taking it out, the speaker cover may be filled with water and the device’s audio may be muffled. This is normal. In such a case, shake off the water that’s inside the speaker cover lightly and the audio will go back to normal.

Differences Between Search Modes
In Field and Beach modes, there are 2 tones.

In Park mode, there are 3 tones.

In the SCORE, the Iron Filter feature is set to a higher level (8) in the Park and Beach modes, and the Field mode to a lower level (3) by default.

SENSITIVITY

Sensitivity is the depth setting of the device. It is also used to eliminate the ambient electromagnetic signals from the surrounding environment and noise signals transmitted from the ground.

• The sensitivity setting is 10 levels for DOUBLE SCORE and 5 levels for SCORE.
• Sensitivity setting is a personal preference. However, It is important to set the sensitivity to the highest level possible where no major popping sounds are heard to avoid missing smaller and deeper targets.
• Sensitivity is a common setting for all modes and changes to this setting will affect them all.

Adjusting the Sensitivity
On the main screen, use the Plus (+) & Minus (-) Buttons to increase or decrease the sensitivity. Single click to change the values one by one or hold down to change them rapidly. The sensitivity value is displayed in the Target ID display.

The Sensitivity Indicator is located on the left side of the Target ID. The indicator consists of 5 bars. Each bar represents 2 levels of sensitivity for DOUBLE SCORE and 1 level of sensitivity for SCORE.

The sensitivity values corresponding to each level on the Sensitivity Indicator are shown below:

The device always starts with the last adjusted sensitivity level.

IMPORTANT!
To obtain maximum depth performance, to eliminate the noise caused by electromagnetic interference, try noise canceling automatically first.

TARGET DEPTH

• The device provides an estimated target depth according to the signal strength during detection.
• Depth Indicator: It shows the target’s proximity to the surface in 5 levels during detection. As the target gets closer, the levels decrease, and vice versa.
• Depth detection is adjusted presuming that the target is a 2.5cm (1’’) coin. Actual depth varies according to the size of the target. For instance, the detector will indicate more depth for a target smaller than a 2.5cm (1’’) coin and less depth for a larger target.

IMPORTANT!
As the operating frequency of the device has a direct impact on the device, the estimated depth may vary for the same target during frequency changes.

FREQUENCY

SCORE offers Multi-frequency (M1/M2/M3), where a wide range of frequencies work simultaneously, as well as 1 single frequency (15kHz).

• You can switch between frequencies easily by short-pressing the Frequency & Noise Cancellation Button. Noise cancellation can be performed by long pressing the same button.
• It is recommended to use Multi-frequency in all modes. When Multi-frequency is selected the letter ‘’M’’ appears on the screen. When a single frequency is selected, the frequency is shown numerically on the screen.
• Frequency only affects the mode currently selected; changes made in one mode do not affect the others.
• In areas where there is electromagnetic interference, single frequencies may be less noisy compared to Multifrequency. However, they will be less sensitive to many targets at the same time.

Multi-Frequency

• Multi-frequency which runs multiple frequencies simultaneously gives the user the advantage of covering a broader range of targets on all types of terrains.
• In addition, it offers maximum depth for a large range of metals with different sizes on wet salt beach sand and underwater by minimizing ground noise.

Modes and Frequencies

• Different than the Beach mode, Park and Field modes offer 3 Multi frequencies Multi-1 (M1), Multi-2 (M2), and Multi-3 (M3). M1 is more sensitive to higher conductors while M2 detects lower conductors better.
• M3 is ideal for humid, wet, and/or conductive soils. It reduces the effect of moisture in soils which can cause falses. It also weakens the response of targets generating 10-11 IDs such as coke and aluminum foil.

NOISE CANCELLATION

It is used to eliminate the electromagnetic interference that the device receives from another detector that operates in the same frequency range nearby or from the surroundings (high voltage power lines, cellular base stations, wireless radios, and other electromagnetic devices).

• There are 13 channels available for all frequencies including Multi frequency. The default channel is 1.
• Noise Cancellation only affects the mode and frequency currently selected; changes made in one mode do not affect the other modes or frequencies.
• If too much noise is received when the search coil is lifted in the air, this may be caused by the local electromagnetic signals or high sensitivity level.
• To obtain maximum depth performance, to eliminate the noise caused by electromagnetic interference, try Noise Cancellation first before decreasing the sensitivity.
• Detectors may become noisy due to electrical interference and may exhibit erratic behavior such as loss of depth or unstable target ID. The Noise Cancellation setting allows you to eliminate unwanted noise.

Noise Cancellation

1. Before doing a noise cancellation, lift the device in the air as shown in the picture, and hold it still until the process is completed.
2. You can start the Noise Cancelling by long pressing the Frequency & Noise Cancellation Button.
3. When the process is done, an automatically selected channel number will be displayed and a confirmation sound will be heard.

IMPORTANT!
Noise Cancellation selects the quietest channel based on various criteria. However, sometimes the selected channel may still present some noise.

TARGET ID
Target ID (2-digit number in the middle of the screen) is the number produced by the metal detector based on the conductivity of the metals and gives an idea to the user about what the target may be.

• Target ID is shown with two digits on the display and ranges between 01-60.

• SCORE’s Target ID scale consists of 30 lines and each line represents 2 Target IDs.

• In addition to showing the Target ID in the middle of the screen, the ID is also marked with a small cursor under the ID scale.

  • Ferrous range is 1-10.
  • Non-ferrous range is 11-60.

• In some cases, the device may produce multiple IDs for the same target. In other words, the IDs may be jumpy. This may result from several factors. Target orientation, depth, purity of the metal, corrosion, mineralization level of the soil, etc. Even the direction of the search coil swing may cause the device to generate multiple IDs.

• In some cases, the device may fail to provide any ID. The device needs to receive a strong and clear signal from the target to provide an ID. Therefore, it may not be able to provide an ID for targets at fringe depths or smaller targets even if the device detects them.

• Keep in mind that Target IDs are “probable”, in other words, estimated values and it would not be possible to know the properties of a buried object exactly until it is dug out.

• IDs of non-ferrous metals such as copper, silver, aluminum, and lead are high. The target ID range of gold is wide and may fall within the same range of metal wastes such as foil, screw caps, and pull tabs. Therefore, if you are looking for gold targets, digging out some trash metals is expected.

• Coins searched throughout the world are made of different metals and in different sizes in different geographical locations and historical eras. Therefore, to learn the Target IDs of the coins in a specific zone, it is suggested to perform a test with the samples of such coins, if possible.

• It may take some time and experience to make the best use of the Target ID feature in your search area. Different brands and models of detectors produce different Target ID numbers.

DISCRIMINATION PATTERNS

SCORE offers advanced discrimination settings to users for easier operation.

• By using the Pinpoint & Discrimination Button, you can select one of the 3 different discrimination pre-set patterns and 1 separation pattern that is completely under the user’s control.
• The default discrimination pattern for Park, Field, and Beach modes is the ‘’F’’ discrimination pattern which stands for Ferrous Off.
• In SCORE, two IDs are rejected or accepted at the same time.
• The discrimination setting only affects the mode currently selected; changes made in one mode do not affect the others.

All Metal Discrimination Pattern
In this pattern, all IDs are accepted on the ID scale (1-60). In other words, all the lines on the scale are visible and no ID is rejected. The device will emit an audio response for all metals as well as the ground and their IDs will be displayed on the screen.

Ground Off Discrimination Pattern
In this pattern, the device will not receive ground noise and will not provide any audio or Target ID for it. Target IDs 1 and 2 are turned off (rejected) and the rest are open (accepted).

Ferrous Off-Discrimination Pattern
In this pattern, the device will not provide any audio or Target ID for ferrous targets. Target IDs 1 – 10 are turned off (rejected) and the rest are open (accepted).

Custom Discrimination Pattern
This pattern allows users to create their discrimination pattern according to the type of targets they would like to accept and reject. Rejected IDs will vary based on the search mode.

Accepting and rejecting IDs are also referred to as ‘’notch’’ and this function is only available on the DOUBLE SCORE model.

The default, accepted, and rejected IDs in the Custom Discrimination Pattern for each mode are shown in the table below:

Default Discrimination Patterns

Selecting a Discrimination Pattern
The discrimination pattern changes each time you press the Pinpoint & Discrimination Button on the main screen.

PINPOINT
Pinpoint is to find the center or the exact location of a detected target.

SCORE is a motion detector. In other words, you are required to move the search coil over the target or the target over the search coil for the device to detect the target. The pinpoint mode is a non-motion mode. The device continues to give a signal when the search coil is kept stationary over the target. When the Pinpoint & Discrimination Button is pressed, unused icons are cleared from the screen. PP appears on the screen.

In the pinpoint mode, the device does not discriminate metals or provide Target IDs.

To perform pinpoint:

1. After a target is detected, move the search coil aside where there is no target response and push the Pinpoint & Discrimination button.
2. Keep the button pressed down and bring the search coil closer to the target slowly and parallel to the ground.
3. Signal sound becomes stronger and changes in pitch while getting closer to the target center and the bars in the ID Scale start filling up from the outside to the inside.
4. Mark the position which provides the loudest sound using a tool or your foot.
5. Repeat the above procedure by changing your direction 90°. Actions to be performed from a couple of different directions will narrow the target area and provide you with the most exact details of the target location.

SETTINGS

To enter the settings menu, press the Power & Settings Button once. Once the button is pressed all the settings will be displayed at the bottom of the screen. The selected setting will be framed. For better visibility, it will flash and its value will be displayed on screen.

• You can navigate through the settings using the Right & Left Buttons.
• You can adjust the value of a setting using the Plus (+) & Minus (-) Buttons.
• Press the Power & Settings Button once to exit the settings menu.

1. Ground Balance (DOUBLE)

   • DOUBLE SCORE is designed to work without ground balancing on most terrains. However, for experienced users and on highly mineralized grounds, ground balancing will bring extra depth and stability to the device.
   • Ground balance can be performed in 2 ways with DOUBLE SCORE: Automatic and Manual.
   • Ground balance only affects the mode currently selected; changes made in one mode do not affect the others.
   • The device ground balances between 0-20 in the Beach mode and within the range of 0-99 in all other modes.
     Automatic Ground Balance
     Automatic ground balance is performed as follows in all search modes:
   1. Find a spot where there is no metal.

2. Press the Power & Settings Button to scroll to the ground balance setting and press and hold the Pinpoint & Discrimination Button. The ground balance icon will start blinking in the info section at the top and the ground balance value will be displayed in the middle of the screen. If no ground balancing has been performed before, this value will always be zero (0).

3. Start pumping the search coil up and down from about 15-20 cm (~6’’- 8’’) above the ground down to 3 cm (~1’’) off the ground with smooth movements and keeping it parallel to the ground.

4. Continue until the audio reduces in response to the ground. Based on ground conditions, it usually takes about 5-6 pumps for the ground balance to be completed.

5. Upon completion of the ground balance, the ground balance value is shown in the Target ID section on the display. To ensure that the ground balance is proper, ground balance at least 2-3 times and check the ground balance values on the display. In general, the difference between the values shall not be higher than 1-2 numbers.

6. If you cannot ground balance, it means that either the ground is too conductive or not mineralized or there is a target right below the search coil. In such a case, retry ground balancing at a different spot.

IMPORTANT:

• DOUBLE SCORE automatically resets the Ground Balance value to zero (0) when Ground Balance cannot be done in Park and Field modes.
• After performing Automatic Ground Balance in Beach mode, if the Noise Cancellation feature is activated, please Ground Balance again for better detection.

Manual Ground Balance
Allows you to manually modify the ground balance value. It is not preferred mostly because it takes time. However, it is the preferred option in cases where a successful ground balance cannot be performed using other methods or minor corrections are required to the automatic balance.

1. Find a clear spot without metals.
2. Press the Power & Settings Button to scroll to the ground balance setting. The ground balance value will be displayed in the middle of the screen.
3. You need to listen to the sounds coming from the ground to perform manual ground balance. Pump the search coil up and down from about 15-20 cm (~6’’- 8’’) above the ground down to 3 cm (~1’’) off the ground with smooth movements and keeping it parallel to the ground.
4. If you are getting a low tone while pumping the coil, it means that you should increase the ground balance value using the Plus (+) Button. On the other hand, if you are getting a high tone, you should decrease the ground balance value using the minus (-) button.
5. Continue the above process until the ground response is eliminated.
   • The ground balance value may vary in single frequency and Multi-frequency in certain soil types.
   • The sound may not be eliminated on certain terrains. In this case, if the ground noise is minimized, it means that the ground balance has been done.

Ground Tracking

• The device tracks the changes in the ground during detection and updates the ground balance automatically. Ground changes that are not visible will affect the depth and discrimination performance of the detector.
• Press the Power & Settings Button to scroll to the ground balance setting. Press the Pinpoint & Discrimination Button once. In the info section, at the top of the screen, the ground tracking icon will appear.
• The device updates the ground balance automatically as long as the search coil is swung over the ground. It does not provide any feedback to the user.
• Tracking is suitable for use in areas where different soil structures are present within the same land or in fields where mineralized rocks are scattered widely apart. If you use ground tracking in areas where hot rocks are intensely present, the device may not be able to eliminate these highly mineralized rocks or you may miss the smaller or deeper metals.

Ground Balancing on the Beach

• In DOUBLE SCORE, users are provided with a Stability setting in addition to Ground Balance. This setting reduces noise and false signals received from the ground on the beach, allowing for more convenient searches.
• Users, if they wish, can achieve the most suitable settings for their surroundings by performing an Automatic Ground Balance. Alternatively, they can adjust the Stability to best fit their detection conditions.
• In Beach Mode, users can adjust the Ground Balance between -1 and -5 to select the appropriate Stability level for the environment.
• The zero (0) level of the Ground Balance represents the most stable level. Decreasing the Stability level towards -5 may increase the noises originating from beach sand and enhance the probability of detecting weak conductive metals like gold, which give an 11 ID.

Recovery Speed (DOUBLE)
The Recovery Speed setting adjusts the speed of the target response.

• It allows for separation between multiple targets nearby.
• Recovery Speed setting enables you to detect smaller targets among trash or ferrous targets.
• DOUBLE SCORE Recovery Speed setting can be adjusted between 1 and 3 with 1 being the slowest and 3 being the fastest.
• Recovery Speed setting only affects the mode currently selected; changes made in one mode do not affect the others.
• When the Recovery Speed setting is set to a low number, the ability of the device to detect targets nearby decreases but its depth increases.
• Similarly, a high Recovery Speed setting (for example 3) will increase the ability of the device to detect targets nearby but will decrease the depth.
• It is recommended that you practice with different metals placed close to each other before starting to use this setting.

Adjusting the Recovery Speed
Press the Power & Settings Button once. Select the Recovery Speed setting using the Right & Left Buttons. The current value will be displayed on the screen. Change the value of the Recovery Speed using the Plus (+) & Minus (-) Buttons.

Press the Power & Settings Button once to go back to the main screen.

IMPORTANT!
Increasing the Recovery Speed allows for a faster sweep rate with less chance of missing targets. Increasing Recovery Speed at the same sweep rate will help to eliminate ground noise but it will decrease detection depth.

• If you encounter high levels of ground noise on beach sand or underwater, try increasing the Recovery Speed.

Default Recovery Speed Settings

Iron Filter (DOUBLE)
Iron Filter allows desired non-ferrous targets in trashy sites, previously masked by iron, to be detectable.

• The Iron Filter (IF) setting ranges between 0-9 in the Park and Field modes and 1-9 in Beach mode. The default value is 3.
• This setting only works when Multi Frequency is selected.
• Iron Filter setting only affects the mode currently selected; changes made in one mode do not affect the others.
• Level 9 will become handy when trying to discriminate some unwanted mid-conductors such as shotgun cartridges as iron.
• A lower IF setting will increase the probability of ferrous targets being classified as non-ferrous targets and vice versa.

Adjusting Iron Filter
When the device is working in Multifrequency, Press the Power & Settings Button once. Select the Iron Filter feature using the Right & Left Buttons. The display will show the current Iron Filter value. It can be adjusted using the Plus (+) & Minus (-) Buttons.

Volume
This control allows you to increase or decrease the device’s volume based on your preference and environmental conditions.

• Volume setting consists of 6 levels and it is set to 3 by default. When you turn off and on the device, it will start with the last volume level you chose.
• This setting is common to all modes; changes will take effect in all modes.

Adjusting the Volume
Press the Power & Settings Button once. Select volume using the Right & Left Buttons. The current value will be displayed on the screen. Change the volume level using the Plus (+) & Minus (-) Buttons.

• Press the Power & Settings Button once to go back to the main screen.
• Because the volume level affects power consumption, we recommend you not to increase it more than necessary.
• You can connect wired headphones to the device with the headphones adapter cable sold separately. The volume for the headphones is also adjusted through the volume setting of the device.
• When wired headphones are attached, the headphones icon will appear in the info section at the top of the screen.

Backlight
It enables you to adjust the display backlight level according to your personal preference.
