The Sea Hunter MKII has donned Garrett’s famous black and yellow colours with an 8″ PRO-formance Submersible search coil adorning the end of the stem. Although the colour isn’t to everyone’s taste, it gives this machine a friendly bumble bee look.

Powered by eight AA batteries, the Garrett Sea Hunter MK II will last for at least 22 hours. Its regular operating frequency is 15kHz but this is interchangeable for each users preferences.

This detector model is great for diving, underwater treasure hunting, jewellery, coins, relics, wet sand hunting and generally will pick up all other metals. It also comes with waterproof headphones and the controller is hip mountable to save arm strain.

What are the Pros and Cons of the Garrett Sea Hunter MKII Metal Detector?

  • Lightweight – Weighing between five and six pounds, this won’t be too much of a bother to lift, especially when under water.
  • Intermediate/Expert – This Garrett model has been recommended for more seasoned detectorists, so if you’re looking to upgrade, this is a great option.
  • Underwater Functionality – This is the best Garrett metal detector for under water relic hunting.
  • All Terrain Functionality – Even though this product is designed for under water detecting, it’s great on land as well.
  • 1 Year Warranty – Whilst this isn’t a very long warranty, it’s still useful to have just in case your metal detector should malfunction .
  • Learning – As this model is aimed at experts, new detectorists will have to put forth some effort in learning how to operate this machine.
  • Price – At over £700, this detector is a bit pricy, but when you think of the technology it uses and its functionality, it might just be worth it.
  • Quality – Some customers have noted that the stem is a bit flimsy, this generally comes down to customer preference, but hopefully this isn’t a major problem.
  • Display – There is no display on this metal detector.
  • Pinpoint – There is no pinpoint or depth indication, which is very disappointing considering if you’re under water or even on land, you’d like to have these included in the manufacturing.
  • Ground Balance – There is no ground balance, we assume it has been factory pre-set, which isn’t ideal.

Overall, this Garrett detector is a good machine, especially when it comes to underwater treasure hunts. It lacks in quality and technology in some areas but ultimately, it has great potential and will help its owner to find those all important treasures.

[amazon fields=”B006J61ZKS” value=”thumb” image_size=”large” image=”2″]


For the AT Pro, Garrett have done away with the bumble bee black and yellow colours and given this model a sleek black appearance. An 11″ Semi Elliptical Search Coil is just the cherry on the cake.

Being powered by four AA batteries gives the AT Pro a long battery life. It functions on a 15kHz operating frequency but there is no other option for the frequency which will irk some detectorists.

This detector is great for coin hunting, jewellery hunting, relic hunting, cache hunting, prospecting and beach/fresh water hunting. It truly is an all rounder!

[amazon fields=”B006J61ZKS” value=”thumb” image_size=”large” image=”3″]

What are the Pros and Cons of the Garrett AT Pro Metal Detector?

Garrett ACE 400i

[amazon fields=”B01DYAEGSE” value=”thumb” image_size=”large” image=”1″]

Main Features

  • Iron Audio – Distinguishing between the treasure and the trash is made easier with an iron audio setting.
  • Target IDA digital target ID identifies each metal that is detected.
  • 5 Search Modes – These modes include: Custom mode, Jewellery mode, Relics mode, Coins mode and All Metal mode.
  • 8 Sensitivity Modes – Sensitivity will play to the advantages of the user as it enables them to fine tune their metal detecting experience.


The Garrett ACE 400i is the next step up from the ACE 400, the difference is minute, the ‘i’ simply stands for ‘international’, meaning it doesn’t conform to the usual US coin system Garrett utilises.

The exterior of the Garrett ACE 400i is, unsurprisingly, yellow and black. These are generally good colours but to me, it feels like I’m on a building site. A more sleek and tidy appearance as well as proper styling would make this detector look a bit more appealing, like the AT Pro.

The ACE 400i is powered by four AA batteries contributing to an impressive 20 hour battery life. A 10 kHz operating frequency is utilised, aiding the user to find smaller or bigger targets.

An 11″ PRO-formance DD Submersible Search Coil is included and some sellers sell the ACE 400i with extra accessories. Overall, it is simple to understand and well manufactured.

[amazon fields=”B01DYAEGSE” value=”button”]


What are the Pros and Cons of the Garrett ACE 400i Metal Detector?

  • ValueAt just £340, this Garrett detector is well priced without being too expensive.
  • Lightweight – Weighing around 3lbs you won’t have to worry about carrying it around begrudgingly for long hours.
  • Recommended – The ACE 400i has received a lot of praise from keen detectorists, adding to its good reputation.
  • Easy to Use – When it comes to using Garrett metal detectors you need to understand how to use each one effectively. Thankfully, this Garrett model is easy to understand and use.
  • Warranty – A two year warranty is available with the purchase of this item.
  • Mineralised Soil – Whilst the Garrett ACE 400i generally works quite well, it does give off a few false signals when it’s near highly mineralised soils.
  • Design – Garrett needs to be a little bit more daring, even if it’s black and yellow, give us a better design that isn’t so block like.

[amazon fields=”B01DYAEGSE” value=”thumb” image_size=”large” image=”1″]


The Garrett ACE 400i does run the risk of falling into the trap of being just another generic metal detector, but it really wows us with its value for money and great user friendly functions.

Garrett EuroACE

[amazon fields=”B004779ZQW” value=”thumb” image_size=”large” image=”1″]

Main Features

  • Deep Detection – A detector needs to do more than just scan over the surface, it really needs to dig deep and the Garrett EuroACE does just that.
  • 5 Search Modes – These helpful modes include: Custom mode, Jewellery mode, Relics mode, Coins mode and All Metal mode.
  • High-Res Iron Discrimination This mode is used for separating the iron rubbish from the more valuable metallic treasures.
  • Lightweight – Weighing only 2.7lbs this detector is the lightest of all the Garrett metal detectors listed.


Garrett have been determined to stick with yellow and black on their metal detectors exteriors, this is repetitive and irksome but we can forgive Garrett as it’s kind of their calling card. An 11″ PRO-formance DD Search Coil sits at the end of the stem, a larger sized search coil is handy when searching a large area.

Four AA batteries power the EuroACE for long hours of detecting. With a 8.25 kHz operating frequency, the user will be able to get the best out of their metal detecting experience, frequencies help the metal detector to accurately pinpoint large or small objects. Target ID, Sensitivity and Pinpoint are also important functions that work within this machine.

It’s good to note that the EuroACE is easy to set up and to use which is all the user will need.

[amazon fields=”B004779ZQW” value=”thumb” image_size=”large” image=”2″]

What are the Pros and Cons of the Garrett EuroACE Metal Detector?

  • Value – Joint at the top with the ACE 300i, this is the best Garrett metal detector regarding price. It can be purchased for just over £260. This is well worth the money!
  • Beginners – The EuroACE is easy to understand and use so it’s perfect for beginners.
  • Accuracy – The accuracy on this Garrett model has impressed numerous customers as well as us.
  • Warranty – There is a two year warranty included with this item.
  • Wet Sand – The EuroACE isn’t the best in wet and salty sand conditions, often giving out false signals.
  • Volume Control – The sound on the EuroACE has irritated some detectorists as they aren’t able to control it, however, this isn’t a major fault.

[amazon fields=”B004779ZQW” value=”thumb” image_size=”large” image=”3″]


The Garrett EuroACE is a great machine for its price and we can see this will appeal to many people including beginners. Its ease of use just makes it even more desirable.

  • Target ID – A target ID is key in identifying the types of metal underneath the surface.
  • 5 Search Modes – These modes include: Custom mode, Jewellery mode, Relics mode, Coins mode and All Metal mode.


The Garrett ACE 300i is the next model up from the ACE 250. The ACE 250 was quite a popular model but we believe the Garrett ACE 300i will knock the ACE 250 out of the park.

Four AA batteries power this Garrett model for hours of metal detecting fun. As noted before the ACE 300i has adjustable frequency but its set to operate at 8kHz.

A 10″ PRO-formance Submersible Search Coil sits at the end of a yellow and black exterior.
Some accessories are also available to purchase with this item from specific sellers.
