ACE 400i™ | TOP mid-range detector - with headphones!
.jpg)
The Garrett ACE 400i is the top model in the ACE series. The metal detector belongs to the best-selling series among entry-level metal detectors. Garrett has given the most popular series an "i" update. The Garrett ACE 400i brand metal detector is characterized by the identification of objects using target IDs on the display. Even better metal discrimination is possible thanks to sharper audio tones and the proprietary "Iron Audio" tone. Precise object pinpointing is no issue thanks to the built-in PinPointer. The metal detector operates at 10 kHz, offering even more depth and sensitivity for the tiniest objects. The light weight of 1.32 kg and the easy-to-use system make the metal detector interesting for the whole family and children as well. The modern technology, robust construction, and sporty yellow design ensure years of searching pleasure.

The five preset search programs make searching even easier, as you just set them and start searching. Additional features and a powerful DD search coil (in comparison to the Garrett ACE 300i) make it interesting for advanced searchers. Eight sensitivity levels can be set, and by adjusting the notch pattern, trash finds can be avoided.

The metal detector is ideal for searching for coins, relics, treasures, and small nuggets.
Simply switch on, select the search program, and start detecting!
ZERO-DISC - all metals
JEWELRY - jewelry objects
CUSTOM - operator settings
RELICS - lead, brass, bronze are detected - iron objects are filtered out
COINS - coins (filters out trash objects like iron and metal foil)
plus Pinpointer function (extra button)
The search depth depends on the ground conditions, search coil, and the object size. The ACE 400i can detect large objects up to a maximum of 150 cm.
Waterproof search coil
The search coil is waterproof, and you can search in shallow water at lakes or on the beach in the water. The control box must not get wet. It should be protected from rain.

Identify metals by conductor number
The "Digital Target ID" helps to identify metals. Shape, size, and type of metal determine the target ID. Iron and steel have a low target ID. Bronze, silver, lead, medium-sized jewelry, ... have a medium target ID. Gold, larger jewelry, and large coins have a very high target ID. With higher mineralization, the target ID increases.
Identify metals by sound
The ACE 400i produces three different tones. Low-conductivity objects have a low tone, medium-conductivity metals produce a mid-level tone, and high-conductivity metals result in a bell tone. Iron Audio allows particular metals to be heard (normally muted). For example, bottle caps and washers can be heard with this.
