In terms of the design, the Garrett ACE 400i looks a lot like the other ACE models with the exception of a cross-shaped coil. This metal detector consists of a shaft, a PRO Performance 8.5″ x 11” DD coil, and a 400i control box. The shaft ends in a comfortable arm rest that comes equipped with an adjustable Velcro strap. There is also a coil cover available which can be snapped on with ease.

In addition to the comfort factor, the other advantage with the ACE 400i is the weight. Weighing in at just 1.32 kg, you are definitely not going to get tired carrying this detector around. But, it is not recommended for kids, see the best metal detectors for kids here. It also has an adjustable length of 1.06 meters to 1.29 meters.

Iron audio may not always be useful; it all depends on the terrain. You'll probably want to turn it off if there's a lot of iron trash around to prevent getting bombarded with signals. Now, this comparison is a bit different as the AT Pro is a little pricier ( see price ) of a device than the ACE 400. It has a higher frequency of 15kHz compared to the 10 kHz of the 400, meaning the AT Pro offers improved sensitivity to smaller items and better distinction of close targets.

However, it's ideal for places with limited iron trash. If you're tired of being duped into digging garbage targets like bottle caps, iron audio gives you more detail about what you've discovered and helps you improve your find to junk digging ratio. We’d advise getting some accumulator batteries for Garrett ACE 400, which will significantly save money when using the device. The control unit It would basically inform you if it believed the target was made of a specific metal, such as iron, gold, copper, silver, and so on. A coin will ring out the high bell while low conductivity will sound out lower. It’s pretty easy to figure out. You can adjust the newly upgraded ‘pulse width modulation’ system to your audio preference. Practice makes perfect: Spend time in the field practicing with your Garrett ACE 400. The more you use the detector and interpret Target ID numbers, the better you’ll become at distinguishing between various types of targets. Start by detecting in familiar areas or places with known targets to improve your understanding of the Target ID system.There are eight sensitivity levels to choose from. In my experience, each degree of sensitivity corresponds to roughly 1 inch of depth most of the time. It isn't a precise calculation. Even if my sensitivity is set to level 1, I can hear stuff 2 inches deep. And when my sensitivity is set to level 8 I can hear targets 10 inches deep, making it a deep seeking metal detectors. TreasureNet Forum: This is a popular online forum where metal detector enthusiasts share their experiences, tips, and advice on using various metal detectors, including the Garrett ACE 400. You can browse and participate in discussions to learn more about target identification and other aspects of metal detecting. https://www.treasurenet.com/forums/metal-detecting/ It is quite easy to operate the Garrett ACE 400, as we mentioned earlier. Even a novice can easily get started by reading the manual. Due to its great accuracy, lightweight construction, and superb performance, it’s also pleasurable to use in the field. Ground balance, on the other hand, is totally absent on the ACE 400. However, in most situations, this has no effect on the machine's efficiency. It will take some time to get the hang of it, but life will be a little simpler without it. In total, the ACE 400 has 8 different sensitivity levels to choose from. With a push of a button, you can adjust those levels as you work. This might be useful if you’re trying to find smaller items or objects with low conductivity levels. Upping the sensitivity can help you uncover treasures that are buried deeper into the ground.

Unfortunately, the ACE 400 is not made for saltwater use. It’s not protected from oxidation caused by saltwater. Plus, there is no ground balance feature to overcome mineralization issues. In comparison to other metal detectors, Garrett’s ACE metal detectors have basic control boxes that are identical. Everything is labeled, and the display is clear – albeit you’ll have to squint in harsh sunshine. Mode, discrimination, and sensitivity are all important toggles. There are other controls for audio and frequency. AudioEssentially it would tell you if it thought the target was a particular type of metal such as iron, gold, copper, silver, etc.
