Garrett has been a leading name in metal detection since 1964, and the Ace series is one of their most popular series. The Ace 400 was introduced as an upgrade to the earlier Ace models. It offers more advanced features while keeping the simplicity that users love. It became a favourite among detectorists for its balance of performance and price, continuing Garrett’s legacy of quality and innovation.

Now, let’s dive into the features that make the Garrett Ace 400 a great choice for metal detecting.

Digital Target ID

The Ace 400’s Digital Target ID is one of its most impressive features. It ranges from 0 to 99 and provides a numeric value to help you identify the type of metal before digging. For example, higher numbers often indicate more valuable metals like silver or copper, while lower numbers can signal iron or other less desirable materials. 

I have found this feature especially useful when hunting for coins and relics. It helps to avoid unnecessary digging which saves both time and energy. The accuracy of the Target ID is something that I can rely on.

Iron Audio

Iron Audio allows you to hear the iron content in a target. It gives you the ability to distinguish between trash and treasure. This is particularly useful in areas with a lot of iron debris, such as old houses or construction sites. In my experience, this feature has been a real game-changer. 

It reduces the frustration of digging up nails or other junk, allowing me to focus on finding valuable items. I can turn Iron Audio on or off, which helps me choose which signals to check.

Adjustable Frequency

The Ace 400 metal detector offers an adjustable frequency of 10 kHz. It is ideal for reducing interference from other metal detectors or electrical sources. This is a crucial feature when detecting in areas with high electromagnetic activity, such as near power lines or in crowded locations where multiple detectors are in use.

I have found that adjusting the frequency gives me clearer signals and helps me identify targets more accurately. It is also helpful in areas with a lot of ground minerals, where interference can be a problem.

Pinpointing Mode

The pinpointing mode on the Ace 400 helps you find your target more accurately. Once you have identified a potential target, you can switch to pinpointing mode to narrow down the exact location of the target. This feature is simple to use and extremely effective, speeding up the recovery process. 

I’ve used it extensively in both open fields and forested areas, and it has significantly reduced the amount of time spent searching for a detected item. This mode is particularly handy when you are dealing with small targets or items that are buried deeper underground.

Search Coil

The Garrett Ace 400 comes with an 8.5″ x 11″ DD PROformance search coil. This coil is both waterproof and designed to offer excellent depth and coverage. This makes it flexible enough for various areas, including wet sand and shallow water. 

I have tested it in a variety of conditions; from sandy beaches to rocky trails. I found it to be highly effective in all environments. The coil’s large coverage lets me cover more ground with each sweep, while its depth capabilities allow you to detect items buried deeper than with standard coils.

Audio Tone ID

The Ace 400 offers three distinct audio tones which are low, medium, and high. This Audio Tone ID feature makes it easier to identify the type of metal without even looking at the display. While detecting, I have found this to be a very helpful feature, especially when I am focused on detecting and don’t want to keep glancing at the screen. 

The distinct tones quickly tell me whether it’s worth digging, making my hunts more productive.

Notch Discrimination

Notch Discrimination allows you to selectively filter out certain types of metals from your search, further refining your detecting process. For example, you can choose to ignore signals from pull tabs or other specific types of junk metal. I have used this feature when searching in parks or areas where there’s a lot of modern trash, and it has been incredibly effective. 

It makes the detecting process more efficient by focusing only on the types of targets I’m interested in.

Graphic Target Analyzing

The Garrett Ace 400 is equipped with a Graphic Target Analyzing (GTA) feature, which provides a visual representation of the target’s conductivity on the screen. This graphical display shows the probable type of metal by indicating its position on a segmented bar graph. The segments help you quickly determine whether you’re dealing with something valuable, like a coin, or a less desirable item, like a piece of foil.

From my experience, the Graphic Target Analyzing feature is extremely useful, especially for quickly assessing targets in the field. The visual feedback allows you to make a more correct decision about whether to dig or move on. I have found it particularly handy when searching in areas with a lot of mixed metals, as it gives a clearer picture of what might be buried.

Lightweight and Beautiful Design

Finally, the Ace 400’s lightweight and beautiful design makes it comfortable to use for long periods. Its weight is just 2.9 lbs which makes it easy to handle, even during long detecting sessions. The adjustable armrest and padded grip ensure that your arm doesn’t tire out quickly, which is a big plus when you’re spending hours in the field. 

The design is not only practical but also contributes to a more enjoyable detecting experience. I have found that the balance of the detector is just right, allowing for smooth, controlled sweeps without pain.

I have been using the Garrett Ace 400 extensively, and it impressed me with its overall performance and features. The Digital Target ID and Graphic Target Analysis provide clear, helpful information about what I am detecting. This makes it easier to decide whether to dig. 

Iron Audio and adjustable frequency are game-changers, allowing for better control and fewer false signals. The pinpointing mode and large search coil make locating the targets more efficient. Overall, the Ace 400 combines ease of use with advanced features, making it a standout choice for both new and experienced metal detectors.
