Uncover Gold with Ultra-Fine Pulse Induction Technology: VLF Sensitivity, PI Power, Affordable Excellence!
Designed & Assembled in Australia by ALGOFORCE PTY LTD

Introduction

Metal detectors serve as indispensable tools for treasure hunters and gold prospectors. 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, 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 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 can also help to estimate size or conductivity through its stable conductive target ID (0-99), 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 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 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 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.

NOTE: The strength of the E1500 lies in its sensitivity to small nuggets. Therefore, we have only tested the E1500 with small to medium coils. The largest coil we tested is the NF 14”x9” Evo. Although larger coils with electrical parameters in spec will work with the E1500 control box without any problem, the shaft could rotate slightly and become wobbly when extra-large and heavy coils are used. The shaft is made of 3 pieces of carbon fiber rods. The lower piece cannot rotate with respect to the middle piece. However, the middle piece can rotate freely with respect to the upper piece when the upper hand-tighten spin lock is released. This is by design. This design offers advantages such as the ability to rotate the coil for compact storage and accommodating users who prefer a slight tilt in the handle for comfort. For small to medium-sized coils, the upper hand-tighten spin lock can firmly secure the middle piece when tightened. However, for extra-large and heavy coils, it could become slightly loose. Please also note that over-tightening the spin locks could cause damage to them.

Quick Start

Main Detection User Interface (UI)

Press Volume/Vibration buttons to modify Audio Volume. Hold Volume/Vibration buttons to adjust Vibration. Press the Backlight Adjust button for backlight control. Use the Minus and Plus buttons to modify Sensitivity.
To adjust other settings:

1. Press Right/Auto GB 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.

I. Power On
Connect the power bank to the control box and turn it on. To power the detector, hold the Power On/Off button for 3 seconds, then release. Repeat to turn it off.
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. 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 Auto FS process takes 50 seconds. The noise levels of the scanned frequencies will be displayed.
V. 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.
VI. Perform Auto Ground Balance (Auto GB)
(to eliminate ground response)
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.
VII. 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.
VIII. 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. 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.
The Conductive Target ID (0-99) displayed in the Pinpoint UI remains stable even in highly mineralised soils. 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: C.ID Pinpoint, C.ID 5 Tones and C.ID 100 Tones. ‘C.ID’ stands for Conductivity Target ID. Users can seamlessly switch between audio settings by briefly pressing the Right/Auto GB button while in pinpoint mode.
C.ID Pinpoint:
As in previous software releases, in C.ID Pinpoint audio setting, audio pitch correlates with signal strength, with higher pitches indicating stronger signals. Tailored for precise pinpointing of target locations.
C.ID 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.
C.ID 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.
In C.ID Pinpoint audio setting, users retain the ability to adjust the audio threshold through the Threshold setting. In both C.ID 5 Tones audio setting and C.ID 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.

User Settings

Audio Volume: Modify by pressing the Vol/Vibration buttons.
Vibration: Adjust by holding the Vol/Vibration buttons.
Pinpoint mode has separate volume and vibration controls from the main detection mode.
Backlight Level: Control by pressing the Backlight Adjust button.
Sensitivity: Modify in the Main Detection UI or the Pinpoint UI using the Minus and Plus buttons.
To adjust other settings:

1. Press Right/Auto GB 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.

5. 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.

6. 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.

7. 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.

8. 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.

9. 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.

10. 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 ofall sizes and is suitable for most situations. When used in combination with the Nugget Finder 8″x6″ Sadie coil or similarsized 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 coil or similar-sized coils, it delivers outstanding performance, even in 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 coils larger than the Nugget Finder 14″x9″ Mono coil, this mode excels, even in highly mineralised soils. This combination is highly recommended for locating large gold nuggets in different ground conditions. The four detection modes are not just designed for detecting gold nuggets. They can also be used for finding jewellery, coins, and other treasures.
    With a small coil like the Nugget Finder 8″x6″ Sadie, use Ultra-Fine or Fine detection mode for fine treasures. For a large coil like the 14″x9″ Evolution Mono, employ Normal or Large Gold mode for deep discoveries.
    In general, no ground balance is needed on beaches, except for black sand beaches. As a PI detector, the AlgoForce E1500 naturally rejects seawater signals; the detection mode dictates the level of rejection, ranging from Ultra-Fine to Large, becoming more aggressive.

11. 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”.

12. 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.

13. 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.
    You can switch between a dark or light display theme by holding down the Backlight Adjust button.

Release Note for Software V1.1.0

Software Version 1.1.0 was release on 23/05/2024, which brings a highly anticipated feature: Audio Treble Setting (patent pending). This new functionality allows users to finely tune the audio treble output to their personal preferences.
Key Features:
Audio Treble Setting:
Different headphones exhibit varying audio frequency responses, leading to inconsistent audio experiences. Some headphones may dampen high-frequency components, thereby reducing clarity.
Additionally, older users may experience decreased sensitivity to high frequencies, which are crucial for generating the crisp and sharp audio needed for effective metal detection. Conversely, excessive high-frequency components can render audio harsh and unpleasant. Therefore, optimal levels of high- frequency components should be customized to individual users and their respective headphones or speakers.
With the ability to adjust the treble, users can now enhance or diminish the prominence of higherpitched sounds, thereby influencing the overall tonal balance of the audio.
Increasing the treble yields a brighter, crisper sound, while decreasing it produces a softer, mellower sound.
This feature offers users the flexibility to tailor audio feedback to align with their individual detecting styles, whether they prefer crisper or softer audio responses.
Optimised Coil Selection Interface:
The interface has been redesigned for easier understanding during the coil calibration process.
Progress indicators now show which detection mode is being calibrated. Detailed messages guide users on actions to take if a coil is deemed not optimal, enhancing the overall user experience.
Finer Adjustment Step for Audio Threshold:
The adjustment step for the Audio Threshold has been fine-tuned, allowing for much smoother adjustments. This enhancement enables precise control, setting the audio threshold just to the point of audibility, making it easier to detect very faint target signals.
This update ensures that our metal detector is more adaptable and user- friendly, catering to a wider range of audio preferences and improving the coil calibration process.

Release Note for Software V1.0.9

Software version 1.0.9 was released on 08/04/2024, introducing two additional audio settings within the pinpoint (non-motion) mode: C.ID 5 Tones and C.ID 100 Tones. The original pinpoint audio setting is named C.ID Pinpoint, with ‘C.ID’ standing for Conductivity Target ID. Users can seamlessly switch between audio settings by briefly pressing the Right/Auto GB button while in pinpoint mode.
C.ID Pinpoint:
As in previous software releases, in C.ID Pinpoint audio setting, audio pitch correlates with signal strength, with higher pitches indicating stronger signals. Tailored for precise pinpointing of target locations.
C.ID 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.
C.ID 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.
In C.ID Pinpoint audio setting, users retain the ability to adjust the audio threshold through the Threshold setting, consistent with previous software releases. In both C.ID 5 Tones audio setting and C.ID 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.
These enhancements aim to provide users with greater flexibility and improved target identification capabilities.

Release Note for Software V1.0.8

Software V1.0.8 was released on 13/02/2024. The following changes were made with respect to the previous software V1.0.7:

1. The activation time for a long key press function has been reduced from 1.5 seconds to 0.7 seconds. For example, the time duration between pressing and holding the ground balance key and the commencement of actual ground balancing is now 0.7 seconds, as opposed to 1.5 seconds.
   Other functions requiring a long key press are similarly affected, including vibration adjustment and auto frequency scan.
