Garrett Ace 400i Metal Detector Review

An honest and comprehensive Garrett ACE 400i review & buyers guide.

With Garrett Ace models being on the shelves for years now finally Garrett have created a new line of the ACE series. So how do they shape up?

The Garrett Ace 400i metal detector is the top spec model of the new ace line also available are the Garrett ace 200i and the 300i.

Garrett have opted to stick with the ACE theme in terms of design and colour, keeping the detector yellow and black.

Garrett ACE 400i Appearance & Assembly

Upon opening the box the simplicity of the Garrett Ace machines are still there, with only 3 pieces to combine it won’t take you long to assemble and out the door hunting. The control box, the stem and the coil and wire are all very easily assembled together.

They have kept the Garrett Ace 400i comfortable to use with the soft padding around the forearm rest and hand grip and still features the velcro strap to secure to your arm. You may need it more with this detector as it’s not as light as it’s predecessors, still not too heavy though!

The design of the Ace 400i allows you too easily navigate the control panel with your thumb keeping the buttons within easy reach.

Probably a little to heavy for kids, the Garrett 400i is still great for beginner adults who want the more advanced and experienced features. For the price Garrett have managed to give you some features that can only be found on detectors twice it’s price.

Garrett ACE 400i Modes & Features

The Garrett Ace 400 has 5 modes as follows: Zero Discrimination (same as all metal) Jewellery, Custom, Relic and Coins. It also has only 6 buttons these are Power/Iron Audio, Mode, Sensitivity, Frequency Adjustment, Discrimination and Pinpoint mode.

The LED display has a few new features in comparison to the discontinued ACE line. Battery level indicator, sensitivity indicator, discrimination notches, coin depth meter and a target identification number.

The custom search mode on the Garrett Ace 400i can be used to customise your search, notching out different discrimination patterns while accepting or rejecting targets.

The power on button also can be used to turn on the brand new iron audio feature which will allow you to hear the iron you discriminate. This can be very handy when a good target is buried close to iron.

Pinpoint mode is included, if you don’t know what this is then it is used for pinpointing the exact location of a target in a hole.

While keeping the old features of the Garrett ACE detectors, they have added some handy new features making this metal detector a great choice. The new iron audio and target ID numbers, in my opinion really make the Garrett ACE 400i more powerful and effective than it’s predecessors.

Target ID numbers allow you to better understand what is located in the ground with a range of 0 – 99. You will soon get used to these numbers and be able to better determine what you are about to dig.

 

Garrett Ace 400i Frequency

The Frequency of the machine can now also be adjusted to 10khz , allowing a better signal to be produced on items with lower conductivity like gold.

Being able to change the frequency can also help when there is a lot of interference nearby.

Garrett Ace 400i Best Settings

These settings are in my own opinion, please feel free to leave your best settings for the Garrett Ace 400i in the comments.

General Settings for the Garrett Ace 400i

I found the relic mode to be the most productive with sensitivity set to maximum. If your Garrett Ace 400i starts to chatter with the sensitivity set so high simply notch it down until it becomes stable.

Beach Settings for the Garrett ACE 400i

Again with Garrett they have failed to produce an ACE detector that is stable in wet sand this doesn’t mean however that you can’t go beach detecting. Just try to stay in the dry sand to avoid the false signals.

Notch the sensitivity down until the 400i is stable put her in jewelery mode and away you go.

Garrett ACE 400i Depth

Like with all metal detectors the depth capabilities highly depend on the conditions you are detecting in.

The decal display shows 20+ cm, however on a good day in the right conditions expect to find targets with the Garrett Ace 400i at depths a little deeper than this.

Garrett Ace Price & Buyers Guide

To buy the Garrett ACE 400i new expect to pay between £320 – £350

To buy the Garrett ACE 400i used expect to pay between £260 – £310

Summary

As always Garrett have done their job. I’ve played around and tested the Garrett Ace 400i and even though I will always be a fan of the Euro Ace (my first machine) I have to declare the 400i the winner.

With it’s added features the detector seems to be a little more powerful and productive. It’s a little heavier I believe but still a lightweight detector that feels comfortable and sturdy.

Value for money is fantastic you are getting a lot of bang for your buck and features that you would only find on the more expensive metal detectors. Great machine at a great price. Perfect for beginners or as a mid range machine. You will not be disappointed.

    How does the Garrett 400i perform in heavily mineralized soils?

    Is it better in these conditions than the \fisher F44 or F5?

    Thank you

      I’d have to say the Fisher f44 performs much better and with more stability that the Garrett 400i in highly mineralised soils. The Garrett 400 international copes with these conditions but I believe they could have made it perform better Julien. Thanks for dropping by. 🙂
