Stand head and shoulders above the crowds with the Garrett ACE 400 Metal Detector! Highly recommended for coin hunting, ghost town hunting, jewelry hunting, relic hunting, competition events, and dry beach/freshwater hunting (submersible searchcoil only). The king of ACEs, the ACE 400 includes advanced features like Iron Audio, Digital Target ID, and Frequency Adjust to help you dig more treasure and less trash and twice the iron resolution of the best selling Ace 250 to help separate good targets from the adjacent junk iron.

The Garrett ACE 400 metal detector was built for the user who wants an easily customizable device with all the necessary features. Treasure hunters have used this device to find relics, jewelry, and coins on dry beaches, rocky terrain and freshwater. Its versatility in a wide variety of environments makes it perfect for use in competition events and cache hunting. The Digital Target ID – on a 0 to 99 scale – provides with the user with an educated look at what is below their feet. The numbers on the scale corresponds to a list kept by Garrett that can easily be referenced to determine the metallic content of the target. It is handy for those who want to know what kind of things are out there even before they start digging.

The Iron Discrimination Segment is set to four on the Garrett ACE 400 to allow for the treasure hunters to set the discrimination level based on the ground conditions with the Notch Discrimination being adjustable. Five search modes are built into this device including jewelry, relics, coins, zero discrimination and even a custom setting for advanced users. The Target Depth Indicator is designed to show the depth of the target.

Eight sensitivity settings allow for usage in a variety of areas including those with high ground mineralization, near power transformers or even in close proximity to radio signals. The Audio Tone ID Levels provides three separate tones to let the user know the conductivity of the target they've come across. A Battery Condition Indicator is also on board, and alerts the user when a charge is needed, The Iron Audio on the ACE 400 alerts the mid-tone signal range to include targets above the point of discrimination and lets users hear discriminated iron that would otherwise seem like a good target.

What really makes the ACE 400 metal detector 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!

The Garrett 400 55th Anniversary Package + Bonus accessories

Review by T-Mo on January 14, 2020

Well here I am, a novice at metal detection. The great thing about my backyard is it's the entire city of Chicago, Thanks Kellyco, especially Shelby for getting me off the ground. The YouTube videos for this equipment is very user friendly, and since Chicago is the main place with so much history, I am really looking forward to finding Native American relics and more contemporary finds. All pieces were well organized and explained in the box, and assembly (because I watched the videos) was in about 5-7 minutes. Remember what they say about beginner's luck.

Ace 400 Anniversary Pack

Review by Stephen M. on December 06, 2019

I ordered the Ace 400 pack with the detector, Pro Pointer AT and head phones. Kellyco added in a few items as well. The assembly was very easy and the learning curve of the Ace 400 was almost non existent. After about 30 minutes of bench testing with known items, I went outside. In less than 10 minutes, I found a bullet I fired into the ground about 2 or 3 years ago. The process of ordering until the first find was very simple. A huge shout out to Leilani R. With out her assistance, I would still be researching and wondering what my hobby would be. Thank you Kellyco!


Review by Keith on September 05, 2019

Great beginners detector..found several bullets and a silver spoon my first trip out.

Purchased this detector for my son J.A. His first day and first hit was a 2014 Gold Class Ring.

Review by J.A. on August 02, 2019

Order was fast as usual had my machine in one business day after purchase. Does not get better than that. Very pleased with person who took my order and as a previous customer of KellyCo you have only gotten better. Good Job! I have been detecting for 49 years.

anniversary special

Review by great on July 23, 2019

I just wanted to thank Marty for taking the time and explaining the difference with the ace 300 vs the ace 400 which I bought, plus the pin pointer that came with the anniversary special. This is an awesome detector and I am glad Marty told me I would enjoy it. I have been out numerous times since buying it June 1st. If anyone is looking to talk to someone Marty is the one, Thanks again Marty
