Garrett Ace 400i metal detector

The new Ace 400i metal detector incorporates the latest Garrett technology, which was launched in 2016. This device is ideal for finding coins, relics, treasures and jewelry.

This device has improved iron discrimination, manual ground balance, graphic object analysis, one-touch, iron tones, pinpointing and more precise object identification with numbers.

The Ace 400i is the top model in the Ace series. The value for money of the Garrett Ace is very good. For example, this Garrett Ace 400i digital metal detector has a search frequency of 10 Khz and five search modes for jewelry, coins, relics or all metals. You also have the option of creating your own user modes. The object identification (metal type recognition) can be easily read on the display and also a depth display in cm. Unwanted iron items like nails and bottle caps can easily be excluded from your search process. The Ace 400i has an extra strong camlock rod attachment for very stable and comfortable search movements.

Higher search frequency
The Ace 400i with its 10 KHZ has a higher search frequency than the earlier Ace models (6.5 KHZ-Ace 150, Ace 250, Euro Ace, Ace 200i and 300i) The advantage of this 10 KHZ higher search frequency is the improved sensitivity to low and medium conductive objects (gold, lead etc.)
DD search coil for good depth range
Equipped with the Proformance DD search coil 21.5 x 28 cm (8.5 "x 11") for additional depth performance and precise point allocation. This search coil reduces the negative effects of mineralized soils. You will be able to get a good range of depth. Up to 35 cm for objects the size of a coin, up to a maximum of 125 cm for large objects.
Numerical object identification (1-99)
The Ace 400i metal detector has both segment identification and numerical object identification (1-99). As soon as the metal detector detects an object, a tone is heard and a number appears in the center of the display. Each number represents a type of metal. (For example, No. 76 euro coin, number 20 iron) For example, you can learn to identify (recognize) objects. To make it even easier, a block appears under the segment bar at the top of the display at the same time. You can read about the type of metal what the object can be. (e.g. iron). In addition, the Ace 400i has 3 different audio tones. A low tone for iron, a medium tone for gold and other objects, and a high tone for silver.
You can adjust the sensitivity (depth) yourself, as well as the discrimination. The Eiser discrimination of the Ace 400i is very accurate and even better.
Iron audio / iron tone
The Iron Audio feature allows the user to adjust the volume for iron, which makes the iron signal easier to hear, or it can be turned off completely so you won't hear a sound if iron is detected. This function contributes to the better detection of iron objects. The advantage of Iron Audio over the discrimination function is that you keep the low range. If you use the discrimination function, it always has a negative effect on your depth range.
Pinpoint location
The Garrett Ace 400i has a pinpoint function as an extra. This is a tool for the exact location of objects. This allows you to find the position of the object more precisely and so you have less work to dig up the object.
The notch function enables you to discriminate very precisely. You can now even discriminate against certain ID sigments.
Frequency switch
To prevent interference with other metal detectors and electronics, the Ace 400i offers a frequency switch. If your detector is interfered with by other detectors, you can easily change the frequency.
Waterproof search coil
The Ace 400i has a waterproof search coil, only the display is not waterproof. So you can use the detector in shallow water as long as the display doesn't get wet. Even when it rains, you have to protect your display with electronic protection.
Reaction speed
This metal detector is characterized above all by its depth range and its fast reaction speed. The latter is especially important when several objects are right next to each other. Most metal detectors only give you a signal. You will notice with the Ace 400i that it lets you hear and see that there are multiple objects.
Good depth performance
With the powerful elliptical and waterproof 21.5 x 28 cm DD search coil (8.5 x 11 inches) you can achieve a good depth range. Up to 35 cm for objects the size of a coin, and up to 1.25 m for large objects.
Excellent price-performance ratio
The easy-to-use system and low weight make the Garrett Ace 400i suitable for the whole family. The robust construction, the modern technology and the sporty yellow design make the Garrett Ace 400i the most popular starter metal detector, with which you will experience years of fun. For quality and good performance, choose a Garrett Ace metal detector!
