Key features include manual and automatic ground balance, iron audio discrimination, and a Pro mode audio option that provides more detailed target information through tone variations. The AT Pro is submersible up to 10 feet, making it suitable for shallow water hunting and rainy conditions.
Users particularly appreciate the AT Pro’s target depth indicator and the ability to adjust sensitivity levels based on ground conditions. The standard 8.5″ x 11″ DD search coil provides good coverage while maintaining decent target separation in trashy areas.
Garrett AT Gold: Specialized for Prospectors
The AT Gold was specifically designed for gold prospecting and operates at a higher 18 kHz frequency compared to the AT Pro. This higher frequency makes it more sensitive to small gold nuggets and flakes, which is crucial for successful gold hunting.
The AT Gold includes a smaller 5″ x 8″ DD coil as standard equipment, which provides better sensitivity to small targets and improved maneuverability in tight spaces. It also features a True All Metal Mode that provides maximum depth and sensitivity without any discrimination.
Additional prospecting features include a high-frequency oscillator for better ground balance in highly mineralized soils and a built-in booster that enhances detection depth in challenging ground conditions.
Garrett AT Max: The Flagship Model
The AT Max represents Garrett’s top-tier all-terrain detector, incorporating Z-Lynk wireless technology and improved iron discrimination capabilities. This model operates at 13.6 kHz frequency and includes features that were previously only available on higher-end detectors.
The Z-Lynk wireless system allows you to connect wireless headphones directly to the detector, eliminating cord interference and providing greater freedom of movement. The AT Max also features improved target separation and a larger LCD screen with enhanced visibility in bright sunlight.
Additional features include enhanced iron resolution with 44 points of iron discrimination, adjustable frequency shift to eliminate interference from other detectors, and improved ground balance range for extreme soil conditions.
Garrett ATX: The Pulse Induction Powerhouse
For extreme conditions and maximum depth, the ATX offers pulse induction technology that excels in highly mineralized soils and saltwater environments. Unlike the VLF detectors in the other AT models, the ATX can detect targets at greater depths and is completely immune to ground mineralization.
The ATX features a unique design with a collapsible shaft and a weatherproof housing that can be submerged to 10 feet. It operates across a wide range of frequencies (30-100 kHz) and includes both PI discrimination and All Metal modes.
This detector is particularly popular among serious gold prospectors and beach hunters who need maximum depth and performance in challenging conditions. However, the ATX requires more experience to operate effectively due to its unique controls and response characteristics.
Key Features Across the AT Series
All AT models share several important features that make them suitable for all-terrain use. The submersible design (typically up to 10 feet) allows hunting in shallow water, streams, and during rainy conditions without concern for damage.
Ground balancing capabilities are standard across the series, allowing the detector to compensate for mineralized soils that can cause false signals or reduced depth. This feature is crucial for maintaining performance in different hunting environments.
Iron discrimination helps separate valuable targets from trash items, though the level of discrimination varies by model. The AT Pro and AT Gold offer basic discrimination, while the AT Max provides enhanced iron resolution with more discrimination points.
Performance Comparison and Selection Guide
Choosing the right AT model depends on your primary hunting activities and experience level. For general coin and relic hunting, the AT Pro offers the best value with professional features at a reasonable price point.
If gold prospecting is your main focus, the AT Gold’s higher frequency and specialized features make it the clear choice. The smaller coil and enhanced sensitivity to small gold targets justify the additional investment for serious prospectors.
The AT Max is ideal for detectorists who want the latest technology and enhanced features like wireless connectivity and improved discrimination. It works well for all-around hunting while providing advanced capabilities for experienced users.
The ATX is a specialized tool best suited for experienced users who need maximum depth in extreme conditions. It requires more skill to operate effectively but offers performance that VLF detectors cannot match in challenging environments.
Accessories and Enhancements
Garrett offers several accessories that enhance the AT series performance. Wireless headphones compatible with Z-Lynk technology provide freedom of movement and eliminate cord interference. Additional search coils in different sizes and configurations allow you to optimize performance for specific hunting conditions.
Pinpointers like the Garrett Pro-Pointer AT complement the main detector by helping locate targets precisely once the general area is identified. This is particularly useful when digging in sand or soil where targets can be difficult to see.
Maintenance and Care
Proper maintenance ensures long-term reliability of your AT detector. After saltwater use, always rinse the detector with fresh water and allow it to dry completely before storage. Check O-rings and seals periodically for wear, especially if the detector is frequently used in water.
Store the detector in a cool, dry place when not in use, and avoid leaving it in direct sunlight for extended periods. The control housing should be kept clean and free from debris that could interfere with button operation or display visibility.
Common Applications and Hunting Strategies
The AT series excels in various hunting scenarios. On beaches, the waterproof design allows hunting in shallow surf and wet sand where valuable items are often lost. The ground balancing feature helps maintain performance in saltwater environments.
For coin shooting in parks and schoolyards, the AT Pro’s discrimination capabilities help separate valuable coins from trash items. The target depth indicator helps determine whether targets are worth digging based on their signal strength.
Gold prospecting with the AT Gold or ATX requires different techniques, including slower sweep speeds and careful attention to ground balance settings. Small gold nuggets often produce faint signals that require patience and experience to identify reliably.
Learning Curve and User Experience
While the AT series is designed to be user-friendly, each model has its own learning curve. The AT Pro and AT Gold are relatively straightforward for beginners to learn, with intuitive controls and clear target identification.
The AT Max adds some complexity with its enhanced features but remains accessible to intermediate users. The wireless technology and improved discrimination require some familiarization but offer significant benefits once mastered.
