They come in two basic types: VLF (very low frequency) and PI (pulse induction), with each technology having its own positive and negative characteristics. In this brief introduction, we will discuss the differences between these two types, and introduce you to the AlgoForce E1500 Plus, a pulse induction metal detector distinguished by its exceptional performance, unique features and cost-effectiveness. VLF metal detectors are effective at locating relatively shallow gold nuggets in soils with low mineralisation, and their generally lower cost makes them an attractive proposition for novices. However, their performance is drastically reduced as soil mineralisation levels increase, and the presence of hot rocks can quickly turn excitement into frustration. PI, or Pulse Induction metal detectors generally provide superior performance in mineralised terrains, being able to ignore most of the minerals you don't want to detect. Virtually all serious gold prospectors opt for PI detectors owing to their ability in handling highly mineralised soils, but when it comes to the detection of small gold nuggets, many pulse induction detectors released in the past have often fallen short in sensitivity compared to VLF detectors. Furthermore, most PI detectors come at a much higher price tag compared to their VLF counterparts. The AlgoForce E1500 Plus is a pulse induction metal detector that excels at locating small gold nuggets in often complex mineralised soils found in most goldfields, all at a remarkably reasonable cost. Developed by AlgoForce Pty Ltd, it harnesses patented Ultra-Fine pulse induction technology, which is capable of detecting even the tiniest of gold nuggets. This sensitivity matches that of VLF gold detectors in low mineral soils, but being a PI detector, it has a bigger advantage in highly mineralised terrains. Additionally, the detector incorporates a dual ground balanced detection channel design, enabling the detection of nuggets of varying sizes. For experienced PI users accustomed to estimating nugget size from audio cues, the AlgoForce E1500 Plus can also help to estimate size or conductivity through its stable conductive target ID (099), even in highly mineralised soils. High single frequency VLF detectors typically struggle with signals on wet ocean sand, where PI detectors are far more capable of detecting through the salt mineralisation. Capitalising on its UltraFine pulse induction technology and stable conductive target ID (0-99), the AlgoForce E1500 Plus excels on the beach, proving to be a versatile tool for searching fine jewellery, coins, rings, and other treasures. With its patented built-in microphone for ambient sound awareness, real-time scrolling detection signal display, a frequency noise level graph for effortless manual frequency selection, ergonomic and lightweight mechanical design, compatibility with aftermarket coils, the convenience of universal USB power bank support, and an integrated loudspeaker, the AlgoForce E1500 Plus emerges as a robust and user-friendly metal detector. This versatile tool has been carefully engineered to cater to the needs of both amateur gold hunters and seasoned prospectors. In conclusion, both VLF and PI metal detectors come with their own array of advantages and limitations. The choice between the two hinges on the user's specific requirements and budget. The AlgoForce E1500 Plus bridges the gap, offering a high-performance, cost-effective PI alternative for users seeking a detector that combines VLF's sensitivity to small nuggets and fine jewellery, but with Pulse Inductions ability to detect in mineralised soils and on beaches. 3 AlgoForce E1500 Key Features Armrest easily adjustable Vibrating motor 2.7" graphic LCD with backlight Loudspeaker Microphone (ambient sound awareness) Powered by common USB power bank (no need for specialised batteries) 3.5mm headphone socket Three-piece telescopic carbon fibre shaft (compact, lightweight, and sturdy) Compatible with GPX 4500/5000 mono coils (Wide range of coil options from Nugget Finder, Coiltek, and others) Lightweight (835g without coil or power bank) Collapsible to 59cm for compact storage 59cm NOTE: Neither the power bank nor the coil is included in the AlgoForce E1500 Plus Basic Package.

The E1500 Plus offers a significantly louder and crisper speaker, making it ideal for environments that require higher sound output. Additionally, while the E1500's headphone connector is positioned at the rear of the control box, the E1500 Plus places it conveniently in the handle, with an extension cable secured along the upper shaft for easier user access. E1500 E1500 Plus Speaker Volume Headphone Connector We redesigned the audio circuit in the E1500 Plus, resulting in significantly louder and crisper speaker volume compared to the original E1500. The headphone connector is situated at the rear of the control box. The headphone connector is positioned within the handle. An extension cable, included in the package, is connected to this internal headphone jack. The other end of the cable is secured to the upper shaft, providing easy access for headphone use. 7 Assembly AlgoForce E1500 8 7 9 2 8 5 1 3 8 6 4 Plug the USB cable and headphone extension cable into the control box.

To do this, press the power button if the power bank has one, or unplug and reconnect the USB cable if it does not. 2. Some power banks may turn on the detector as soon as it's plugged in. 10 AlgoForce E1500 II. Factory Reset (if necessary) Hold the Minus and Plus buttons for 3 seconds in Miscellaneous. III. Calibrate Coil (see Coil Selection in page 13) IV. Select Soil Type (see Soil Type in page 12) V. Perform Auto Frequency Scan (Auto FS) (if necessary to select the quietest frequency to eliminate electromagnetic interference) Activate Auto FS by holding the Return/Auto FS button in the Main Detection UI. The noise levels of the scanned frequencies will be displayed. VI. Set Sensitivity, Audio Settings, and Vibration (to preferred levels) Adjust Sensitivity so that the peak of the Real-time Scrolling Detection Signal is close to the Detection Threshold when there is no target. VII. Perform Auto Ground Balance (Auto GB) (to eliminate ground response if Mineralised Soil Type is selected. No ground balance is required for Mild and Beach Soil Types.) Hold the Right/Auto GB button. Raise and lower the coil until the ground response is minimized or two short beeps are heard, then release the button. The Auto GB In Progress Indicator flashes when Auto GB is in progress. Auto GB can be performed in both the Main Detection UI and Pinpoint UI. VIII. Begin Detecting Keep the coil close to the ground and swing it left and right at a pace of about 1 m/s. Ideally, maintain a constant distance between the coil and the ground surface during the swing to avoid picking up excess ground noise. The detector will continuously monitor the ground drift in the background, presenting it as a horizontal bar in the Main Detection UI. If the Ground Drift Indicator bar widens, initiate Auto GB once more. It is essential to be aware that target signals can influence the Ground Drift Indicator. Therefore, for precise ground drift monitoring, ensure that no targets are detected. IX. Pinpoint detected target (if needed) Enter the Pinpoint UI by pressing the Left/Pinpoint button in the Main Detection UI. In the Pinpoint UI, adjust Sensitivity with the Minus or Plus button. To retune the detection threshold due to ground variation or temperature drift, press the Left/Pinpoint button as needed. Switch audio settings by pressing the Right/Auto GB button. Perform Auto GB if needed by holding the Right/Auto GB button. Return to the Main Detection UI by pressing the Return/Auto FS button. Selected Coil Size Conductive Target ID Sensitivity Pinpoint UI Dual Ground Balance Values Real-time Scrolling Signal Detection Threshold 11 AlgoForce E1500 The Sensitivity and Volume/Vibration settings in the Pinpoint UI are separated from the Main Detection UI. This separation ensures that while the main detection Sensitivity and Volume/Vibration are set for general detection, the pinpoint Sensitivity and Volume/Vibration can be finely adjusted for the accurate location of metal targets. Pinpoint is a non-motion mode where the coil doesn't have to move to indicate a target. The detection signal gets stronger as the coil approaches the target, causing the audio (if audio output is on) or vibration (if vibration mode is on) to intensify. In Pinpoint mode, the detector tracks the target signal peak. When the target signal reaches 90% of this peak, the pinpoint icon on the top centre of the LCD screen will flash, helping users centre on targets more efficiently. If the coil is moved off the target and the signal volume decreases, the flashing stops. Moving back over the target resumes the flashing. As mentioned, pressing the Left/Pinpoint Button retunes the detection threshold due to ground variation or temperature drift. Pressing this button also resets the target signal peak to zero. The Conductive Target ID (0-99) displayed in the Pinpoint UI remains stable even in highly mineralised soils. Generally, a higher number indicates a larger or more conductive target. To obtain an accurate target ID, it is recommended to follow these steps: Move the coil away from but close to the target. Ensure the coil is resting on the ground surface and press the Left/Pinpoint button to retune. After that, slide the coil on the ground surface until the target is positioned just below the centre of the coil. The conductivity target ID is also useful for assessing the target's shape. If the target ID fluctuates significantly when the coil is moved slightly off but still above the target, it likely indicates an irregularly shaped target, such as a bottle cap or a nail with a large head. There are three audio settings within the pinpoint mode: Classic Tones, 5 Tones and 100 Tones. Users can seamlessly switch between audio settings by briefly pressing the Right/Auto GB button while in pinpoint mode. Classic Tones: In Classic Tones audio setting, audio pitch correlates with signal strength, with higher pitches indicating stronger signals. Tailored for precise pinpointing of target locations. 5 Tones: Audio pitch is determined by conductivity target ID, providing distinct audio feedback for different target ranges. Conductivity target ID ranges 0-19, 20-39, 40-59, 60-79, and 80-99 correspond to audio pitches of 330Hz, 490Hz, 650Hz, 810Hz, and 970Hz, respectively. 5 Tones Inv.: Audio pitch varies by conductivity target ID in reverse order. Conductivity target ID ranges 0-19, 2039, 40-59, 60-79, and 80-99 correspond to audio pitches of 970Hz, 810Hz, 650Hz, 490Hz, and 330Hz, respectively. 12 AlgoForce E1500 100 Tones: Each conductivity target ID is associated with a unique audio pitch ranging from 250Hz to 1042Hz. Higher conductivity target IDs produce higher audio pitches, facilitating differentiation of targets. 100 Tones Inv.: Each conductivity target ID is associated with a unique audio pitch ranging from 250Hz to 1042Hz. Higher conductivity target IDs produce lower audio pitches, facilitating differentiation of targets. 5 Tones Inv. and 100 Tones Inv. are added to provide an alternative audio feedback option, leveraging the fact that human ears are more sensitive to high-pitched sounds. When users are searching for highly conductive targets with higher target IDs, 5 Tones and 100 Tones can be used to emphasise these signals. However, when targeting small items, such as small gold nuggets with lower target IDs, 5 Tones Inv. and 100 Tones Inv. can be utilised to highlight these signals with higher-pitched tones, improving detection and identification. In Classic Tones audio setting, users retain the ability to adjust the audio threshold through the Threshold setting. In both 5 Tones audio setting and 100 Tones audio setting, the audio threshold is fixed at zero. This ensures ease of differentiation between conductivity target IDs solely based on unique audio pitches, eliminating potential confusion with the audio threshold. If a pinpointer is used to pinpoint the target and you find that the detector is interfering with the pinpointer, you can turn off the detector's transmitter by double-clicking the Power On/Off button. To turn back on the transmitter, simply press any button. 13 AlgoForce E1500 Ground Balancing Methods in Metal Detectors There are three common ground balancing methods for metal detectors, each with unique advantages and limitations: Manual Ground Balance: This method allows the user to adjust the detector's settings manually to compensate for soil mineralisation. While manual ground balance offers maximum sensitivity to small and deep targets, it requires skill and attention, as the user must listen to feedback and make precise adjustments. Once set, the ground balance remains fixed until the user changes it, making it unsuitable for highly variable ground conditions unless regularly recalibrated. Auto Ground Balance: Auto ground balance simplifies operation by automatically calculating and setting the optimal ground balance based on current soil conditions. Users initiate this process with a simple action, such as pressing a button, making it quick and convenient. Though it does not adapt to changing ground conditions like tracking ground balance, it provides a reliable and efficient setup for most detecting environments without the complexity of manual adjustments. Tracking Ground Balance: Tracking ground balance continuously adjusts in real-time as the detector moves across the terrain, making it useful for highly variable soil conditions. However, the constant adjustments can filter out faint signals from small or deep targets, significantly reducing sensitivity. This trade-off makes tracking ground balance less desirable for detecting in areas where finding small targets is critical. Why the E1500 Plus Uses only Auto Ground Balance The Algoforce E1500 Plus is purposefully designed with only auto ground balance to strike a balance between ease of use and maximum sensitivity. Manual ground balance, while effective, can be intimidating or impractical for new users, requiring constant attention and expertise. Conversely, tracking ground balance risks filtering out weak signals, especially in mineralised soils, making it less suitable for finding small gold. By focusing on auto ground balance, the E1500 Plus simplifies operation, ensuring users can achieve optimal sensitivity without sacrificing performance. The detector's advanced Ground Drift Indicator (G.D.I) display provides real-time insights, allowing users to monitor and adjust settings quickly if necessary. This design mirrors best practices in high-performance detectors, where fixed or auto ground balance settings are often preferred by experienced prospectors for maximising success. The E1500 Plus's auto ground balance empowers users with a combination of precision, simplicity, and confidence, ensuring no gold target--however small--goes unnoticed. 14 AlgoForce E1500 User Settings Audio Volume: Modify by pressing the Vol/Vibration buttons. Vibration: Adjust by holding the Vol/Vibration buttons. Note: Pinpoint mode has separate volume and vibration controls from the main detection mode. Backlight Level: Control by pressing the Backlight/Theme button. Display Theme: Hold the Backlight/Theme button to switch between dark and light display themes. Sensitivity: Modify in the Main Detection UI or the Pinpoint UI using the Minus and Plus buttons. To adjust other settings: 1) Press Return/Auto FS in the Main Detection UI to access the menu. 2) Navigate with Left/Pinpoint or Right/Auto GB. 3) Modify selected setting with Minus or Plus. 4) Press Return/Auto FS to go back to the Main Detection UI. 1. Sensitivity Adjust Sensitivity so that the peak of the Real-time Scrolling Detection Signal is close to the Detection Threshold when there is no target. 2. Audio Threshold Audio Threshold adjusts the volume of the constant background hum added to the detection audio. It's recommended to set it to a level that's just barely audible. 3. Audio Tone The Audio Tone setting adjusts the frequency of the constant background hum added to the detection audio. The tone can be set according to personal preference. 4. Audio Treble Users can adjust the treble to enhance or reduce the prominence of higher-pitched sounds, affecting the overall tonal balance of the audio. Increasing the treble results in a brighter, crisper sound. Decreasing the treble produces a softer, mellower sound. This feature provides the flexibility to tailor audio feedback to match individual detecting styles, whether you prefer crisper or softer audio responses. 15 AlgoForce E1500 5. Soil Type The Soil Type Setting allows users to select the appropriate soil type for their detecting environment, optimising the detector's performance. The available soil types are Mineralised, Mild, and Beach. Mineralised: This option maintains the performance of previous software versions, suitable for mineralised soils. Mild: This option utilises AlgoForce's ZeroGB technology, which disables ground balance to enhance sensitivity for nuggets, coins, and treasures of all sizes in extremely mild gold fields, parks, and fields. Users do not need to perform ground balance when using the Mild option. If the soil mineralisation indicator reads 00 or 01 when you pump the coil up and down, you can try the Mild option. However, if selecting the Mild option reduces sensitivity by 4 or more compared to the Mineralised soil type with proper ground balance, it is not suitable for the soil. In that case, please select the Mineralised soil type. Beach: This option also uses AlgoForce's ZeroGB technology, yet aggressively rejects seawater signals and provides smooth operation on dry sand, wet sand, and even with the coil submerged in seawater. This option offers high sensitivity to coins and treasures commonly found on beaches without the need for the user to perform ground balance. 6. Detection Mode The device offers four distinct detection modes: Ultra-Fine, Fine, Normal, and Large. Ultra-Fine: This is the go-to choice for detecting gold nuggets of all sizes and is suitable for most situations. When used with the Nugget Finder 8"x6" Sadie, the Coiltek 9" Elite, or similar-sized coils, it excels, even in highly mineralised soils. This combination is strongly recommended for locating small gold nuggets in various ground conditions. Fine: Fine detection mode reduces sensitivity to mineralised soil and may not detect very small gold nuggets. When paired with the Nugget Finder 12"x7" Mono coil or similar-sized coils, this mode performs exceptionally well, even in highly mineralised soils. Normal: This mode decreases sensitivity to highly mineralised soil and may not detect small gold nuggets. When used with the Nugget Finder 14"x9" Mono, the Coiltek 14"x9" Elite, or similar-sized coils, it delivers outstanding performance, even in 16 AlgoForce E1500 highly mineralised soils. It is highly recommended for locating medium to large gold nuggets in various ground conditions. Large: Reserve Large Gold mode for use in extremely mineralised soil with high levels of wet salt. When used with the Nugget Finder 14"x9" Mono, the Coiltek 14"x9" Elite, or larger coils, this mode excels, even in highly mineralised soils. This combination is highly recommended for locating large gold nuggets in different ground conditions. There are three Pulse Delay Options for Large Detection Mode, allowing users to optimise detection for various object sizes and reduce mineralisation noise. The Pulse Delay Options allow users to select the time delay between the transmitted pulse and the reception of the return signal. After the primary pulse is transmitted, the detector waits for a short period before it starts to listen for the secondary pulse generated by the metal object. This waiting period is known as the pulse delay. Shorter Delay: Detects weaker signals from smaller objects. Longer Delay: Filters out signals from small, less conductive objects, focusing on larger items. Reduces mineralisation noise in high mineralisation areas for more stable and accurate detection. Large (Pulse Delay 1): Offers balanced performance for objects of all sizes. Audio response is fast and sharp. Large (Pulse Delay 2): Filters out signals from very small objects, focusing on larger items. Audio response is rounded and elongated. Large (Pulse Delay 3): Filters out signals from small objects, focusing on larger items. Audio response is rounded and elongated. Note: Large (Pulse Delay 2) and Large (Pulse Delay 3) can be used to ignore small lead pellets for nugget detecting or small foils for beach detecting. The four detection modes are not exclusively designed for gold nuggets--they can also be used to find jewellery, coins, and other treasures. With a small coil like the Nugget Finder 8"x6" Sadie or the Coiltek 9" Elite, use the Ultra-Fine or Fine detection mode for locating fine treasures. For a larger coil, such as the Nugget Finder 14"x9" Evolution Mono or the Coiltek 14"x9" Elite, utilise the Normal or Large Gold mode for deeper discoveries. 17 AlgoForce E1500 7. Coil Selection In the Coil Selection setting, there are five coil icons, each storing the calibration parameters and the coil size for a different coil. This means the detector can store calibration parameters for up to five coils. If the package comes with a coil, its calibration parameters will be saved as the default parameters for all the coil icons. If it doesn't, the parameters of a factory-designated standard coil will be used as the default. Factory reset does not change the coil icons' calibration parameters or coil size. The coil size of each coil icon can be modified by following these steps: Hold the Return/Auto FS button to enter the coil size editing mode. In this mode, a short underscore appears beneath the coil size number you intend to modify. Use the Left/Pinpoint or Right/Auto GB button to select the coil size number you wish to adjust. Then, make the desired modifications using the Minus or Plus button. To exit the coil size editing mode, press the Return/Auto FS button. After making these adjustments, you will see the selected coil size displayed in both the Main Detection UI and the Pinpoint UI. When you connect a new coil, it's recommended to calibrate it by following these steps: Choose an unused coil icon to save the calibration parameters and adjust its coil size to match the actual coil. Hold the coil in the air, keeping metal and soil at least one meter away. Hold the Minus and Plus buttons until coil calibration starts. Keep the coil in the air during the 25-second calibration process. Coil calibration will be performed for all detection modes one by one. Afterward, the LCD will display "Coil Ready". For some very rare coils, LCD will display "Coil Not Optimal" when Ultra-Fine detection mode is used. In those cases, if you would like to keep using the coil, you need to switch to a different detection mode until the LCD displays "Coil Ready". 8. Frequency Scan The real-time noise level of the selected frequency and the past noise levels from the last Auto FS are displayed in a graph for convenient manual frequency selection. If Auto FS hasn't been run since a factory reset, the past noise levels are displayed as gray bars of equal height. To choose a relatively quiet frequency with a low noise level, press Minus or Plus. Electromagnetic interference often changes. The past noise levels from the last Auto FS may not accurately reflect the current real-time noise levels. If necessary, hold the Return/Auto FS button to update the past noise level to the current real-time noise level. 18 AlgoForce E1500 9. Mic Volume The control box has a microphone that captures ambient sounds, which can then be immediately played back through the headphone. This feature allows the user to simultaneously hear both the ambient sounds and detection audio. The Mic Volume setting allows the user to adjust the volume of the ambient sound playback. To use this feature, a headphone must be connected. 10. Miscellaneous Setting Information about the power supply voltage, firmware version, and hardware serial number can be found in the Miscellaneous setting. To perform a factory reset, hold both the Minus and Plus buttons for 3 seconds. After a factory reset, the coil profiles, including the coil names and calibration data, remain intact, so you don't need to set up your coils again. 19 AlgoForce E1500 Software Upgrade Instruction The AlgoForce E1500 and AlgoForce E1500 Plus share the same software binary file.

The detector has an ambient sound awareness feature for headphone use, but it does not guarantee that all sounds will be heard. Before using in public areas, check local laws and regulations. Avoid disconnecting or connecting the coil to the control box after the unit has been powered up, as doing so could potentially damage the control box. The AlgoForce E1500 Plus is specifically designed to operate with mono coils, utilizing the mono winding for both transmission and reception. While it's technically possible to plug in a DD coil, only the transmit winding would function as a mono coil, as the receive winding would remain open circuit. DD coils are not recommended for use with the AlgoForce E1500 Plus. When using coils heavier than the NF 14"x9" Evo, the shaft may experience slight wobbling despite tightening the spin locks. When the telescopic shaft is fully or nearly fully extended, it may experience wobbling. It is recommended to keep the maximum extension length of both the lower and middle shafts at least 5cm shorter than their full extension length. Over-tightening the spin locks could cause damage to them. 21 AlgoForce E1500 EMC Compliance AlgoForce E1500 Plus has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules.
