Introduction to the Garrett Ace 400
The Garrett Ace 400 metal detector stands as one of the most popular mid-range detectors on the market today. Released as an upgrade to the Ace 350, this model brings enhanced features and improved performance that appeals to both newcomers and seasoned treasure hunters. With its 10 kHz frequency, the Ace 400 offers better sensitivity to low and medium conductivity targets like gold and lead.
The detector comes as a complete package, typically including the ACE 400 control box, submersible search coil, headphones, and instructional materials. Many retailers offer additional accessories like carrying cases and extra coils as part of bundle deals. The suggested retail price hovers around $299.95, making it an attractive option for those seeking quality without breaking the bank.
Key Features and Specifications
Enhanced Target ID and Discrimination
The Ace 400 features a digital target ID system with a 0-99 scale that provides precise information about detected objects. This expanded scale gives you more detailed feedback compared to entry-level models. The five discrimination modes (Zero-Disc, Jewelry, Custom, Relics, and Coins) allow you to filter out unwanted targets efficiently.
Iron Audio and Frequency Adjust
One standout feature is the Iron Audio function, which lets you hear discriminated iron targets. This helps you avoid digging trash while ensuring you don’t miss valuable items with iron components. The frequency adjust feature allows you to change operating frequencies to eliminate interference from other detectors or environmental factors.
Waterproof Search Coil
The included 8.5″ x 11″ DD PROformance search coil is fully submersible up to 10 feet. This makes the Ace 400 suitable for shallow water hunting at beaches or streams. The larger coil size provides better ground coverage and increased depth compared to smaller coils.
Performance in the Field
Depth Capabilities
In practical testing, the Ace 400 delivers solid depth performance for its price range. Users report detecting coin-sized targets at depths of 8-10 inches in moderate soil conditions. Larger objects can be detected at depths exceeding 2 feet. The 10 kHz operating frequency provides good sensitivity to smaller gold items that higher frequency detectors excel at finding.
Ground Balance and Mineralization Handling
The electronic pinpointing feature helps you accurately locate targets before digging. While the Ace 400 lacks manual ground balance, its preset ground balance works well in most soil conditions. But in highly mineralized soils, you might experience some falsing or reduced depth.
Target Separation
The DD coil design provides good target separation in trashy areas. You can effectively distinguish between multiple targets in close proximity, though performance may not match higher-end models with more advanced separation capabilities.
Who Should Buy the Garrett Ace 400?
Beginners
The Ace 400 serves as an excellent entry point for new detectorists. The straightforward controls, clear display, and preset modes make it easy to start detecting immediately. The included instructional materials and Garrett’s extensive online resources provide valuable learning support.
Intermediate Users
For those upgrading from basic models, the Ace 400 offers significant improvements in depth, target identification, and overall performance. The frequency adjust feature and custom discrimination mode provide flexibility for more experienced users.
Specific Hunting Applications
The Ace 400 excels at coin shooting, relic hunting, and jewelry recovery. Its waterproof coil makes it suitable for beach hunting, though the control box is not waterproof. For gold prospecting in mineralized areas, you might consider specialized gold detectors instead.
Accessories and Upgrades
Recommended Accessories
– Garrett Carry Bag: Protects your detector during transport and storage
– Extra 5″ x 8″ DD coil: Excellent for tight spaces and increased sensitivity
– Wireless headphones: Eliminates cord interference during detecting
– Finds pouch: Convenient storage for recovered items
Coil Options
While the standard 8.5″ x 11″ coil works well for general purposes, consider these alternatives:
– 5″ x 8″ DD coil: Better for trashy areas and tight spaces
– 9″ x 12″ coil: Increases ground coverage and depth
– Sniper coil: 4.5″ size for extreme separation in junk-filled areas
Comparison with Competitors
Garrett Ace 400 vs. Fisher F22
The Fisher F22 offers similar features at a comparable price point. But the Ace 400 provides better depth and target ID accuracy. The F22 has slightly better ergonomics but lacks the frequency adjust feature of the Ace 400.
Garrett Ace 400 vs. Minelab Vanquish 440
The Minelab Vanquish 440 uses Multi-IQ technology, providing better performance in mineralized soils. But the Ace 400 offers superior target separation and a more intuitive interface. The Vanquish 440 is priced slightly higher.
Garrett Ace 400 vs. Bounty Hunter Tracker IV
The Tracker IV is a basic model priced significantly lower. While it serves as an entry point, the Ace 400 offers dramatically better performance, depth, and features. The difference in recovery rates and target identification makes the price difference worthwhile.
Maintenance and Care
Regular Maintenance
– Clean the coil after each use, especially after beach hunting
– Check battery contacts monthly for corrosion
– Store in a dry place with batteries removed for long-term storage
– Inspect the coil cable for damage or wear
Troubleshooting Common Issues
If experiencing falsing or erratic behavior:
1. Check battery strength and replace if needed
2. Adjust frequency to eliminate interference
3. Ensure coil cable connection is secure
4. Check for nearby power lines or other interference sources
Tips for Maximizing Performance
Proper Swing Technique
Maintain a consistent swing height of 1-2 inches above the ground. Overlapping each swing by 50% ensures complete ground coverage. Avoid swinging too fast, as this can cause you to miss deeper targets.
Discrimination Settings
Start with preset modes, then gradually experiment with custom settings. For general hunting, a discrimination level around 30-35 on the target ID scale helps eliminate most iron while retaining valuable targets. Remember that some gold rings may read in the iron range.
Audio Tone Adjustments
Utilize the three-tone audio system to identify targets by sound. Lower tones typically indicate iron, mid-tones suggest foil or nickels, and high tones usually represent coins or other valuable targets. Adjusting tone breaks can help you focus on specific target types.
Real User Experiences
Beach Hunting Success
Many users report excellent results using the Ace 400 at beaches, particularly after crowds leave. The waterproof coil allows searching in shallow surf, and the 10 kHz frequency provides good sensitivity to gold jewelry. One user reported finding over $200 in jewelry during a single beach hunt.
Relic Hunting Applications
Civil War relic hunters appreciate the Ace 400’s ability to handle iron-heavy sites. The Iron Audio feature helps distinguish between valuable relics and modern trash. The detector’s performance in fields with moderate mineralization makes it suitable for many historical sites.
Everyday Coin Shooting
For regular coin hunting at parks and schools, users consistently praise the Ace 400’s depth and target identification. The ability to distinguish between different coin types before digging saves time and increases efficiency. Many report finding silver coins at depths exceeding 8 inches.
Conclusion
The Garrett Ace 400 metal detector delivers impressive performance that exceeds expectations for its price range. Its combination of depth, target identification accuracy, and user-friendly operation makes it an excellent choice for both beginners and intermediate detectorists. While it may lack some advanced features of high-end models, the Ace 400 provides the essential functions needed for successful treasure hunting.
Whether you’re searching for coins at local parks, relics at historical sites, or jewelry at the beach, the Ace 400 offers the versatility and reliability needed for consistent results. With proper technique and patience, this detector can provide years of enjoyable detecting experiences and valuable finds.
