Use Iron Discrimination: Adjust the Iron Discrimination feature on your ACE 400 to filter out low-value targets such as iron and steel. By setting the discrimination level appropriately, you can focus on more valuable finds and avoid digging up unwanted items. Garrett marketing specialists have finally heard the users of 6,5×9 inches mono coil and they’ve substituted it with DoubleD 8,5×11” PROformance™. Double-D technology has allowed creating the coil with higher detection depth if compared to mono coil.

The most common situation where ground balancing is needed is when searching in mineral-rich environments such as wet beach sand, gold prospecting areas, or other locations with a significant amount of mineralization. In these regions, the ACE 400 is likely to fall short of expectations. This is to be anticipated, as it has a higher frequency than the 350, which comes in at 10kHz. Not only is the name self-evident, but it is also higher priced than the 250 or 350. The best part about the Garrett ACE 400's frequency is that it is adjustable and you can change the frequency based on what you're searching for. If you're looking for small objects, a higher frequency would be needed. This model is also armed with the Garrett Clearsound Easy Stow Headphones with an inline volume switch. The 400i comes out of the box in three separate parts with the coil, the straight shaft, and the s-shaft separate from one another. You will need no other tools than the ones provided with the metal detector to put it together. Basically, VLF detectors utilize two separate search coils. One is responsible for transmitting electromagnetic waves. When a metal object reflects an eddy current, the second coil will receive the signal to let you know of the object’s presence. This technology is very accurate and is used on most of Garrett’s products. Like all of the products from this brand, the ACE 300 metal detector is well-built. It features the same durable build and user-friendly control box that other models have.

Garrett ACE 400 vs Garrett AT Pro

This metal detector is a single frequency VLF device with 10 kHz operation frequency, but you can adjust it a bit, if needed. Garrett ACE 400 has a function that allows shifting its operation frequency. Search coils are watertight so that you can search along riverbanks. It is important that you remember that control boxes are not waterproof. Wet grass or rain should be avoided when using your machine. Digital Target ID Ok, so I see this question come up quite a bit on the forums. The difference between the 400 and 400i. Metal detectors aren’t hard to find, but these essentials shouldn’t be overlooked when buying one. Weight and Length If you want adjustable ground balancing, you’ll have to upgrade to the AT Pro or AT Max. Target Identification and Discrimination

This particular model comes with a few handy extras that can make all the difference as you prospect. With the detector, you’re getting a search coil cover and a control box cover. The latter accessory slips onto your control box to protect it from light drizzles. The clear plastic window ensures that you can still take advantage of all the functionality the device has to offer. On top of those two protective extras, the machine also comes with a carrying case and Garrett’s EasySound headphones. The ACE 400 comes with 4 AA batteries already installed in the control box. Are headphones included? One of the reasons why Garrett is so respected in this industry is because the company has a reputation for superior quality standards. All of the products are made in Texas and go through a strict quality control process.

Guides and Documents

So what really makes the 400 model an “ace” above its competitors? Let’s dive a little deeper into that. Key Features

The top of the ACE family, the 400 has new Iron Audio feature, a powerful DD coil, a higher frequency, and volume control headphones. In terms of the design, the Garrett ACE 400i looks a lot like the other ACE models with the exception of a cross-shaped coil. This metal detector consists of a shaft, a PRO Performance 8.5″ x 11” DD coil, and a 400i control box. The shaft ends in a comfortable arm rest that comes equipped with an adjustable Velcro strap. There is also a coil cover available which can be snapped on with ease. Garrett created his first metal detector in 1963 after being unsatisfied with the performance he got out of a machine he rented. A year later, Garrett Metal Detectors was founded by Charles Garrett and his wife, Eleanor Garrett. The rest is history. Iron audio may not always be useful; it all depends on the terrain. You'll probably want to turn it off if there's a lot of iron trash around to prevent getting bombarded with signals.Cons are the pre-set ground balancing – but then this isn’t an issue for a beginner, and iron audio that bumps up the price can drive you insane targeting trash. For that reason, mine is usually off.
