Best Features & Benefits

The following are the best features and advantages of the Garrett ACE 400.

Improved electronic pinpointing

With enhanced electronic pinpointing, you can zero-in on your target in the fastest and most efficient manner. By just pressing one button, you can make this metal detector find the object you’re looking for rather than dig through the trash. No need to use a handheld or extra pinpointer. Use the pinpointer with the notch discrimination according to the object that you’re trying to find. With this feature, you can get more success in your hunts than other metal detectors.

With an enhanced adjustable frequency

You can finally find smaller objects like rings, coins, and gold bits because of this metal detector’s adjustable frequency. It also comes with an improved iron resolution to identify iron metals and discriminate it so you can look for more valuable metals.

Comes with all the accessories you need

The ACE 400 comes with the DD waterproof coil measuring 8.5 x 11 inches, large and ready to find smaller precious objects in larger areas. Your purchase also comes with an adjustable armrest strap, a search coil hardware set, a set of AA batteries, a catalog, and an issue of the Garrett Searcher Magazine.

Waterproof and ready

The coil is waterproof and is corrosion-free. This means longer life for your coil and better performance on land and water in all weather conditions. You can take this hunting in the woods, in parks, private lands, at the beach or near streams and brooks.

Easy to use controls

The ACE 400 is known for being one of the easiest to use. The controls are easy to learn with adjustments done digitally. You can make faster and more efficient adjustments on the go.

Large LCD

The LCD is huge, with easy to read numbers, symbols, and labels. You can check the mode you’re in (zero-disc, jewelry, relics, custom mode, or coins) and coin depth (2, 4, 6, and 8+ inches”). With the LCD, adjust the device’s sensitivity levels to find iron, aluminum, gold coins, and jewelry or silver coins.  

Ergonomic features

The handle is well-padded while the armrest is slightly padded but comfortable. A convenient strap keeps the armrest on your arm always. This is great, especially when you’re searching for objects on the beach.


Non-adjustable stem

The only problem with the Garrett ACE 400 is its non-adjustable stem. People who have longer or shorter arms need an adjustable stem to adjust the length of the device according to their needs. This would have been a perfect metal detector if it had this feature.
