The Garrett ACE 400i is a versatile metal detector, perfect for both beginners and experienced users. Operating at 10 kHz, it offers increased sensitivity to valuable metals like gold and lead. It features a waterproof DD search coil, numerical target ID (1–99), notch filtering, and Iron Audio for precise discrimination of iron objects. With its built-in pinpoint function and fast response time, you can efficiently locate targets, even in cluttered ground. The ACE 400i combines ease of use, reliability, and solid construction for years of detecting enjoyment.
The Garrett ACE 400i is an excellent choice for both new users and seasoned hobbyists. Its intuitive interface and user-friendly controls make it easy to operate for everyone. Each button has a dedicated function, ensuring a smooth and enjoyable detecting experience. The digital ACE 400i operates at a 10 kHz frequency and offers five search modes including jewelry, coins, relics, and all metals. You can also save your own preferences in a custom mode. The display shows both the type of metal and the estimated depth in centimeters. Nuisance iron objects like nails or bottle caps can easily be filtered out. A reinforced shaft locking system ensures stable and comfortable sweeping motions during use.
Compared to earlier ACE models (such as the 150, 250, and EuroACE), the 400i operates at a higher frequency of 10 kHz. This frequency is more sensitive to low and medium conductivity targets such as gold or lead, increasing the chance of discovering valuable finds.
The ACE 400i is equipped with a large PROformance DD search coil (21.5 x 28 cm / 8.5 x 11 inches), which improves depth detection and object separation — even for items close together. The coil is waterproof and suitable for shallow water. However, the control unit is not waterproof and should be protected from rain using a protective cover.
The ACE 400i features dual target identification: a segment bar and a numeric scale from 1 to 99. When a target is detected, an audio tone is emitted and a number appears on the screen, corresponding to a specific metal type. An additional indicator on the top bar shows the likely type of metal (e.g., iron). You also receive auditory feedback with three different tones: low for iron, medium for items like gold, and high for silver.
Sensitivity and discrimination settings are fully adjustable. You can exclude unwanted items like nails and bottle caps. The notch function even allows you to eliminate specific ID segments, increasing the likelihood of detecting more desirable targets.
Unlike the ACE 300i, the 400i includes Iron Audio. This lets you adjust or mute the iron tone completely, offering better control over what you hear. The big advantage of Iron Audio over regular discrimination is that it preserves full depth capabilities.
The built-in pinpoint feature helps you accurately locate targets, saving time and effort during recovery, and making the detection process more efficient.
To avoid disturbances from other detectors or electronics, the ACE 400i allows you to manually change the operating frequency. This is especially helpful in crowded detecting areas.
The ACE 400i excels in quick target response. It can detect multiple items that are close together individually — something many detectors struggle with. This gives you a clearer and more complete picture of what lies beneath.
Thanks to its easy operation, lightweight design, and solid construction, the ACE 400i is ideal for adults and also suitable for children from the age of 10. The robust technology, modern look, and reliable performance make it a long-lasting choice you’ll enjoy for years.
