Stand head and shoulders above the crowds with the Garrett ACE 400 Special Metal Detector! As the flagship device in the ACE line, it includes features that help users detect targets that would otherwise be passed over by other competing metal detectors. The ACE 400’s electronic pinpointing makes it easier to hone in on deeply buried treasure than using multiple devices at once. The five built-in discrimination modes allow the user to adapt to the conditions on the ground and its frequency can easily be increased or drawn back based on the type of target that the treasure hunter wishes to find. The best part is that the ACE 400 includes an iron audio feature to hear iron and avoid digging up bad targets that would give good but otherwise false signals.

What really makes the ACE 400 stand out is its versatility in the field. Garrett designed this metal detector to be useful on dry beaches, in fresh water, during competitions, or hiking over rocky soil. It's perfect for picking up coins, jewelry, relics and can even be used for gold prospecting. Built with Garrett’s ingenuity, there’s almost nothing that the ACE 400 cannot find!

Great Detecor for the Price

Review by Scot on June 02, 2017

This was my first detector and I couldn't have asked for more. Well ground balancing would have been great.'s everything it's advertised to be. It can get noisy near power lines but other than that it shines. I've only had it about 3 months but I've found over $15 in change along with a small buck n ball, a rare button and small axe head. I really don't get out much and have yet to dig on a dated property. But I have full confidence this machine will do the job.

As for the service from's the best. I've placed at least 3 orders and all were delivered quickly and intact. Everyone I've spoken to there has been very helpful and friendly. I just ordered an AT Pro just for the ground balancing feature. Stevie Ray was very helpful and gave me some great pointers for setting it up. I highly recommend if you are going to get an AT Pro to speak with him. He's very knowledgeable about it. The Ace 400 will always be with me when I'm out. It was easy to learn and a joy to swing. If you're new to detecting, this machine will not let you down.
