In my opinion, the detector has some flaws and I will focus on them, because many people have already spoken about its advantages. Firstly, it is easy to miss something valuable if it's next to junk; secondly, sometimes it goes off, especially at maximum frequency; sometimes the indicated object depth or the pinpoint mode doesn't work correctly. I don't think these are factory defects. I know it's a fair amount, but overall, the detector is worth recommending, though it's worth paying attention to what you want to use it for.

Ace 400i is okay. But with the Nel Thunder coil, it's a good choice after a few years. The canary talk is just silly. I also have ORX DEUS, which is indeed good for small finds, but together they complement each other. I recommend it.

Solid equipment, worth recommending. The price may not be the lowest, but unfortunately, you have to pay for quality.
