Why the Garrett ACE 400 is a Game-Changer
The Garrett ACE 400 metal detector stands out as a significant advancement for hobbyists. It packs professional-level features into an easy-to-use package. This makes it ideal for anyone looking to start or improve their metal detecting adventures. It offers great value without sacrificing performance.
This detector is designed to be intuitive. Beginners can pick it up and start finding targets quickly. Experienced users will appreciate its depth and discrimination capabilities. It’s a tool that grows with your skills.
Understanding the ACE 400’s Core Technology
At its heart, the Garrett ACE 400 uses advanced technology to find metal objects. It operates at a high frequency of 10 kHz. This frequency is excellent for detecting small targets like gold nuggets and thin silver coins. The detector sends out a signal and listens for echoes from metal.
It features Digital Target ID technology. This gives you a number on the screen for each target. This number helps you guess what the object might be before you dig. It also has a High-Resolution Iron Discrimination. This means you can ignore junk iron targets more easily.
Key Features That Make a Difference
The Garrett ACE 400 comes loaded with features that enhance your detecting experience. It includes five search modes. These modes are preset for different types of targets, like coins or relics. There’s also a Pinpoint mode. This mode helps you zero in on the exact location of a target.
The detector also has adjustable Iron Bias. This setting helps separate iron trash from good targets. It comes with a large 8.5″ x 11″ PROformance™ Double-D waterproof coil. This coil offers excellent depth and coverage. It’s also submersible, so you can hunt in shallow water.
Search Modes Explained
The five search modes on the ACE 400 are:
All Metal: Detects all types of metal. This mode offers the most depth.
Jewelry: Designed to find jewelry items. It ignores most iron.
Custom: Allows you to save your preferred settings.
Relics: Optimized for finding historical artifacts. It detects a wide range of metals.
Coins: Best for finding modern coins. It rejects most ferrous trash.
These modes simplify target identification. They help you focus on what you want to find.
Understanding Target ID and Discrimination
Target ID is shown as a number from 0 to 99 on the LCD screen. Higher numbers usually mean more conductive targets like silver. Lower numbers can indicate iron or foil. Discrimination allows you to set the detector to ignore certain types of metal. For example, you can set it to ignore iron nails.
The ACE 400’s High-Resolution Iron Discrimination lets you adjust the iron level. You can set it to notch out specific iron ranges. This is crucial for finding good targets in trashy areas. It saves you from digging countless rusty nails.
The ACE 400 Coil: Depth and Coverage
The included 8.5″ x 11″ PROformance™ Double-D coil is a major asset. Double-D coils are known for their excellent performance. They offer better depth than simpler concentric coils. They also handle mineralized ground better.
This coil is waterproof. This means you can swing it through puddles or shallow streams. It provides good ground coverage. This helps you cover more area faster. A larger coil can also detect targets deeper in the ground.
Ease of Use for Beginners
One of the best things about the Garrett ACE 400 is how easy it is to use. You don’t need to be an expert to get started. The controls are simple and clearly labeled. The LCD screen is bright and easy to read.
The preset modes mean you can often just turn it on and go. The detector gives you clear audio and visual cues for targets. This helps you learn what different signals mean. It’s a great learning tool for new detectorists.
Advanced Features for Experienced Users
While beginner-friendly, the ACE 400 doesn’t skimp on advanced features. The adjustable Iron Bias is a prime example. Experienced users can fine-tune this setting. This helps them extract valuable targets from heavily littered sites.
The ability to customize settings and save them in the Custom mode is also valuable. This allows you to tailor the detector to specific hunting conditions. The frequency adjustment feature helps reduce interference from other detectors. This is useful when hunting with friends.
What Can You Find with the ACE 400?
The Garrett ACE 400 is a versatile detector. It excels at finding a variety of targets. You can find modern and old coins from different countries. It’s also great for hunting for historical relics like buttons, buckles, and military items.
While not primarily a gold prospecting machine, its higher frequency can detect small gold jewelry. Many users have found rings and other gold items with this detector. It’s a solid all-around performer for general treasure hunting.
Comparing the ACE 400 to Other Detectors
When looking at metal detectors in its price range, the Garrett ACE 400 often comes out on top. Competitors might offer similar features, but the ACE 400 combines them with Garrett’s reputation for quality and reliability. Its build quality is robust. The user interface is more intuitive than many other brands.
For instance, some detectors in this class might have lower frequencies. This limits their ability to find small targets. Others might have less refined discrimination. The ACE 400 offers a balanced approach. It provides excellent value for the money.
Essential Accessories for the ACE 400
To get the most out of your Garrett ACE 400, consider a few key accessories. A good pinpointer is essential. A pinpointer is a small, handheld detector that helps you locate the exact target in the plug of dirt. This saves a lot of time and reduces the size of your plugs.
Digging tools are also vital. You’ll need a sturdy trowel or a digging shovel designed for metal detecting. A finds pouch is useful for storing your discoveries. Headphones are highly recommended. They help you hear faint signals and keep your finds private.
Pinpointer: Garrett Pro-Pointer AT (waterproof and durable)
Digging Tool: Lesche Sampson shovel or a good quality hand trowel
Headphones: Garrett MS-3 Wireless Headphones or wired alternatives
* Carrying Bag: To protect your detector during transport
These items will significantly improve your efficiency and enjoyment.
Tips for Using Your Garrett ACE 400 Effectively
Learning to interpret the sounds and numbers is key. Practice in your yard. Bury different metal objects and try to identify them. Pay attention to the Target ID numbers and audio tones. Learn to distinguish between good targets and trash.
Understand your discrimination settings. Start with lower discrimination levels. This helps you avoid missing good targets. As you gain experience, you can increase discrimination in trashy areas. Always swing the coil smoothly and at a consistent height above the ground.
