Garret Ace 400 Metal Detector

Aimed at beginner to intermediate users, the Garret Ace 400 is a powerful metal detector that has proven to bring results in the field time and time again. With many of the features normally only found on professional detectors, the Ace 400 is a fantastic piece of kit for any serious metal detectorist.

Price: Around $340 US – (£265 GBP)

The ACE 400 includes a higher 10 kHz frequency that provides better sensitivity to low and medium conductivity targets, including gold and lead. The Frequency Adjust feature allows users to toggle between frequency shifts to help eliminate interference from other detectors or nearby power sources.

  • Garrett 8.5″ x 11″ PROformance DD Waterproof Search Coil
  • Electronic pinpointing
  • sensitivity adjustment
  • High-Resolution iron discrimination
  • Depth of find indicator
  • Cam locks

Five discrimination modes:

  • Zero discrimination
  • Coins
  • Jewelry
  • Relics
  • Custom

Build Quality

This Ace 400, like other metal detectors in the Garrett range is well constructed – despite the look of the bright yellow plastic parts. The grip and arm rest are comfortable and make detecting large areas much less effort than traditional grip-only machines.

Garrett have added cam locks to the shaft of the detector which is a great addition. They allow you to securely attach all the sections of the shaft, stopping them from wobbling.

Control buttons are big and easy to locate on the clear and bright display and are easily managed by using your thumb.

Weight

Weighing in at just 2.9 pounds, the Ace 400 is comfortable to use for extended periods of time. With the arm rest and full sized grip, the whole machines actually feels very light. We used this machine in a field for over 8 hours straight and good have detected for even longer. It felt balanced and accurate.

Accessories

With this particular bundle you receive the following items:

  • Garrett 8.5″ x 11″ Search Coil Cover
  • ClearSound Headphones
  • Garrett ACE Rain Cover
  • Adjustable Arm Strap
  • Garrett ACE 400 Instruction Manual
  • Garrett Search Coil Hardware Kit
  • 4 “AA” Batteries
  • FREE Garrett Catalog
  • FREE Garrett Searcher Magazine
  • Exclusive 2 Year Warranty

Depth Of Finds

How deep your metal detector will locate an item isn’t an exact science. Many factors have to be taken into account including the ground type/condition and the type of metal you are searching. Add to that the size of the object and you can see that there is no exact answer – but we did try the Ace 400 over a period of 2 weeks at many locations and would say that it happily locates small items from 8 to 12 inches deep – and that it amazing for such an affordable metal detector.

Headphones

The bundled ClearSound headphones are very comfortable and well made but we would probably replace them with something more high-end going forward. They have an in-line volume switch (which is essential as the Garrett Ace 400 does not have a headphone volume control).

Iron Discrimination

The ACE 400 has a fantastic feature called Iron Audio. When iron is detected the detector will emit a low ‘grunting’ noise. This can save you lots of time digging up worthless pieces of rusted iron or the endless piles of ring pulls and bottle caps. This is a feature that is normally only found on much higher end metal detectors.

Made in the USA 🇺🇸

Garrett are a trusted name in the metal detecting world and made right here in the USA since 1964. Their products are sold worldwide and are used by many thousands of metal detector enthusiasts. We also reviewed the Garrett 1140900 Pro-Pointer AT Waterproof Pinpointing Metal Detector. You can read our review about it here.

Conclusion

We loved using the Garrett Ace 400 and would recommend it to any serious amateur metal detector enthusiast. With its affordable high end features and accurate pinpointing you are sure to be making finds pretty much straight out the box. Its a comfortable machine to use and can be tweeked to suit most users tastes (discrimination modes/frequencies).

We liked it so much we bought two for the team.
