The Garrett ACE 400i is an advanced metal detector designed for people who want reliability, accuracy and full control over the search process. It is perfect for detecting gold jewelry, relics, silver rings, gold coins and many other valuable finds. Its advanced features make it an ideal choice for searching for coins as well as jewelry or antique artifacts.
The frequency adjustment function makes it possible to eliminate or minimize interference from electrical installations and other metal detectors. This solution is especially useful when searching in areas with a high volume of electronics or at rallies and group field searches where multiple devices are operating simultaneously.
The digital target identifier offers a numerical identification scale from 0 to 99, which accurately determines the conductivity of the detected metal. This lets you know which object you are dealing with even before you start digging, significantly increasing efficiency and saving time.
The electronic detection, or stationary All-Metal mode, helps determine the exact location of a detected object with surgical precision. This allows for faster and more efficient excavation of finds, without unnecessarily ditching a large area.
The Iron Check function provides increased resolution (more pixels) for more precise iron discrimination levels. This feature is extremely useful in areas littered with metal debris, where valuable objects can be masked by unwanted items such as nails or sheet metal fragments.
Graphic Target Analyzing™ simultaneously displays the conductivity of the detected object and the current discrimination pattern. This gives you a complete picture of the signal and allows you to make an informed decision about whether a target is worth digging up.
ACE™ 400I Iron Audio technology lets you hear rejected iron signals that are muted by default. This allows you to identify unwanted flat objects, such as caps or washers, before you decide to dig. In order to use this function, it is necessary to set the iron discrimination level - in the demonstration it is 35. Without Iron Audio, the cap and silver coin sound very similar, while when the function is activated, the cap generates characteristic murmurs of iron, signaling that it may be a waste.
