Introduction to the Garrett ATX
The Garrett ATX is a professional-grade pulse induction (PI) metal detector designed for serious gold prospectors and treasure hunters. Released in 2013, this detector quickly gained recognition for its exceptional depth capabilities and performance in highly mineralized soils. Unlike traditional VLF detectors, the ATX uses pulse induction technology to ignore ground mineralization, allowing users to detect deeper targets in challenging environments.
Key Specifications
The ATX features a 12-inch DD search coil that provides excellent ground coverage and depth. Operating at a frequency of 730 pulses per second, it can detect targets at impressive depths – often reaching 2-3 feet for coin-sized objects and even deeper for larger items. The detector weighs approximately 6.9 pounds with batteries and comes with a rechargeable battery system that provides 20+ hours of use on a single charge.
Performance in Different Terrains
Gold Prospecting Capabilities
The ATX truly shines when it comes to gold prospecting. Its pulse induction technology allows it to ignore highly mineralized ground that would overwhelm VLF detectors. In Australia’s gold fields, where the soil can be extremely mineralized, the ATX consistently outperforms many other detectors. The adjustable threshold and sensitivity settings allow users to fine-tune the detector for specific conditions, making it possible to detect even small gold nuggets at impressive depths.
Beach Hunting Performance
Saltwater beaches present unique challenges for metal detectors due to the high mineralization and conductivity of wet sand. The ATX handles these conditions exceptionally well, maintaining stable operation where many detectors would produce false signals. Its waterproof design (up to 10 feet) makes it perfect for shallow water hunting, and users report excellent performance for finding jewelry and coins in both wet and dry sand conditions.
Advanced Features and Technology
Pulse Induction Technology
The ATX uses advanced pulse induction technology that sends powerful, short bursts of current through the search coil. This creates a magnetic field that penetrates deep into the ground, detecting targets based on their conductive properties. Unlike VLF detectors that can be affected by ground minerals, PI technology ignores these minerals, allowing the ATX to maintain stable operation in challenging environments.
Ground Track System
The Ground Track feature automatically adjusts the detector’s ground balance to changing soil conditions. This is particularly useful when hunting in areas with varying mineralization levels. The ATX offers four track speeds, allowing users to choose between fast response for trashy areas or slower tracking for more stable operation in consistent ground conditions.
Practical Usage Tips
Optimizing Settings for Different Targets
For gold prospecting, start with a moderate sensitivity setting and adjust upward until you experience instability. Use a slow sweep speed and overlap your sweeps by at least 50%. When hunting for coins and relics, reduce the discrimination level to accept all metals – the ATX’s depth capabilities mean you’ll still get good target separation even with lower discrimination settings.
Coil Control Techniques
Maintain a consistent height above the ground, ideally 1-2 inches, to maximize depth and sensitivity. Keep the coil parallel to the ground and avoid lifting it at the end of each sweep. The ATX’s DD coil design provides excellent ground coverage, but proper technique is essential to achieve optimal performance.
Accessories and Modifications
Recommended Accessories
The Proformance DD Search Coil Cover is essential for protecting your investment. Consider the Garrett Master Sound Headphones for improved audio response and better target identification. The ATX Camo Backpack provides convenient storage and transport for the detector and accessories.
Optional Search Coils
While the standard 12-inch DD coil is versatile, some users prefer the smaller 10×12-inch concentric coil for improved target separation in trashy areas. The larger 20-inch Deepseeker coil is available for those seeking maximum depth in open areas, though it does sacrifice some sensitivity to small targets.
Maintenance and Care
Regular Maintenance
After each use, especially in saltwater environments, rinse the detector with fresh water and dry thoroughly. Check the coil cable for any signs of wear or damage. Clean the control housing with a damp cloth and avoid using harsh chemicals. Store the detector in a cool, dry place away from direct sunlight.
Battery Care
The ATX’s rechargeable battery system requires proper care for optimal performance. Fully charge the battery before first use and avoid completely discharging it. If storing the detector for extended periods, charge the battery to about 50% and recharge every three months to maintain battery health.
Comparisons with Other Detectors
ATX vs. Minelab GPX Series
While the Minelab GPX series is often considered the gold standard for serious gold prospecting, the ATX offers comparable performance at a lower price point. The GPX series may have slightly better sensitivity to small gold, but the ATX’s user-friendly interface and automatic ground tracking make it more accessible to intermediate users.
ATX vs. Garrett AT Max
The AT Max is Garrett’s top-of-the-line VLF detector, offering excellent performance in moderate ground conditions. But in highly mineralized soils, the ATX’s pulse induction technology provides superior depth and stability. The AT Max is lighter and easier to swing for extended periods, making it better suited for general-purpose detecting.
Common Issues and Solutions
Audio Threshold Problems
If you experience inconsistent audio threshold, check the headphones connection and ensure the threshold control is properly adjusted. Sometimes, electromagnetic interference from power lines or other sources can affect the threshold. Try adjusting the frequency shift setting to eliminate interference.
Ground Balance Issues
In extremely mineralized ground, you may need to manually adjust the ground balance. Use the manual ground balance feature and take several ground samples to find the optimal setting. If the detector becomes unstable, reduce the sensitivity setting until operation stabilizes.
Real-World Performance Examples
Gold Field Success Stories
In the Australian gold fields, ATX users have reported finding gold nuggets weighing several ounces at depths exceeding 12 inches. The detector’s ability to ignore hot rocks and maintain stable operation in highly mineralized soil has made it a favorite among serious prospectors in these challenging environments.
Relic Hunting Applications
Civil War relic hunters have found the ATX particularly effective for locating deep targets like cannonballs and buried fortifications. Its pulse induction technology allows it to detect large iron objects that would be missed by VLF detectors, making it invaluable for historical site surveys.
Conclusion
The Garrett ATX represents a significant investment in metal detecting technology, but for serious gold prospectors and treasure hunters working in challenging ground conditions, it delivers exceptional performance. Its pulse induction technology, combined with user-friendly features and robust construction, makes it a powerful tool for finding deep targets in mineralized soils. While it may have a steeper learning curve than some VLF detectors, the ATX’s capabilities make it well worth the effort for those seeking to maximize their detecting success in difficult environments.
