Release Date: 10/9/2026

Overview

Version 4.0.0 introduces Tracking Ground Balance and refined signal filtering, building on the usability improvements introduced in Version 3.0.0.

Key highlights include:

• New Tracking Ground Balance for smoother operation over variable ground.
• Two tracking speeds to suit different rates of ground variation.
• Refined filtering for quieter operation and slightly improved sensitivity.

What’s New in V4.0.0

1. Tracking Ground Balance

In Version 3.0.0, Auto Ground Balance is performed by holding the Right/Auto Ground Balance button while pumping the coil up and down. Once the button is released, the ground balance remains fixed until Auto Ground Balance is performed again.

Based on user feedback, Auto Ground Balance may need to be performed frequently when detecting over rapidly changing ground. To improve operation in these conditions, Version 4.0.0 introduces Tracking Ground Balance.

Briefly press the Right/Auto Ground Balance button to cycle through three ground balance modes:

• Fixed Ground Balance
• Tracking Ground Balance Speed 1
• Tracking Ground Balance Speed 2

In any mode, perform Auto Ground Balance by holding the Right/Auto Ground Balance button while pumping the coil up and down. When the button is released, the ground balance remains fixed in Fixed mode or continuously adjusts as the detector moves across the terrain in either Tracking mode. Speed 2 tracks ground changes faster than Speed 1.

Tracking Ground Balance has been field-tested and shown to provide a much smoother detecting experience over variable ground, particularly in highly mineralised soil.

Recommended Ground Balance Settings

• Continue using Fixed Ground Balance when the ground is relatively consistent.
• Select Tracking Speed 1 if Auto Ground Balance needs to be performed frequently because the ground changes over short distances.
• Tracking Speed 1 is recommended for most variable ground because it provides effective ground tracking while reducing the risk of tracking out small targets.
• Select Tracking Speed 2 only when Speed 1 cannot keep up with rapid ground changes.
• For best results, perform Auto Ground Balance over clean, target-free ground at the start of each detecting session, after changing the ground balance mode, or whenever noticeable ground noise occurs.

2. Refined Filtering

The detector’s filtering has also been refined in Version 4.0.0.

You may notice:

• Quieter and more stable operation.
• Slightly improved sensitivity.

Compatibility and Installation

• Compatible with all existing E1500 and E1500 Plus units.
• Please follow the standard firmware update process outlined in the user manual.
• The AlgoDownloader firmware upgrade tool is currently available only for Windows PCs.
  
  
  
  
   
  

The AlgoForce E1500 series, comprising the E1500 and E1500 Plus, is a pulse induction metal detector that excels at locating very small gold nuggets in often complex mineralised soils found in most goldfields. Developed by AlgoForce Pty Ltd, it harnesses proprietary 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. 

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 series 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 a Pulse Induction detectors ability to detect in mineralised soils and on beaches.

Built for Prospectors & Treasure Hunters
The E1500 Plus combines the sensitivity of a VLF with the depth of a PI, designed in Australia for goldfields everywhere. While perfect for prospectors, it also excels for coin and relic hunters, delivering versatile performance on various terrains.

Two User Modes
Standard and Advanced Modes for both entry-level and experienced users, offering flexibility and ease of use.

Proprietary Ultra-Fine Pulse Induction Technology
Our Ultra-Fine Pulse Induction technology delivers exceptional sensitivity and stability on mineralised ground and black sands. Three selectable soil types—Hot, Mild, and Beach—optimise performance across a range of conditions, from extreme goldfields to dry sand and saltwater environments.

Extreme EMI Resistance
Use near power lines or in suburban areas with minimal interference. Explore untouched sites with confidence!

Precise Target Identification
Detect gold with fewer digs. Unique on-screen target ID helps you focus on valuable targets. It significantly boosts efficiency in trashy goldfields, making detecting faster, easier, and more productive.

Wide Range of Coil Options
Compatible with GPX 5-pin mono coils, including options from Coiltek, Nugget Finder, and more. Select the best setup for your needs!

Convenient USB Power
Powered by a common USB power bank, the E1500 Plus offers flexibility and affordability with high-capacity options for extended runtime—no need for specialised batteries. A lightweight 10,000mAh power bank provides approximately 10-12 hours of runtime.

Lightweight Design
Weighing under 850g without coil or battery, and under 2kg with a small coil and battery, the E1500 Plus is the lightest pulse induction gold detector available, built with a durable carbon fibre shaft.

Adjustable & Portable
Easily extend, collapse, or store the telescopic shaft, which adjusts for ergonomic use in tight spaces or on the go.

Free & Intuitive Software Upgrades
Ongoing R&D delivers continuous software upgrades that boost performance and unlock new features—constantly expanding your detector’s capabilities at no extra cost.

Australian Support & Warranty
Backed by a 2-year warranty, with comprehensive support from AlgoForce and authorised dealers.
