Garrett ACE 300 Review
The ACE 300 is a straightforward 8 kHz entry detector with 0–99 target ID, five search modes and electronic pinpointing. It is easy to understand, but its non-submersible control box and fixed ground balance define the ceiling.
Bottom line
Easy to learn, but only compelling at a genuinely entry-level price
The ACE 300 makes sense for dry parks, yards and inland coin hunting when the priority is familiar controls and replaceable AA batteries. Its 7 x 10 in concentric coil gives tidy pinpointing, while the 0–99 ID is more informative than icon-only entry machines. Buyers expecting wet-salt stability, manual ground balance or a waterproof control box need a different detector.
Decision table
Garrett ACE 300 specifications that matter
| Decision factor | Documented position | Practical consequence |
|---|---|---|
| Frequency | 8 kHz single-frequency VLF | Determines how the machine approaches targets and changing ground. |
| Water protection | waterproof coil only | Separate housing protection from wet-salt stability. |
| Best user | beginners hunting parks and yards | A poor match wastes features or creates avoidable limitations. |
| Strongest feature | simple 0–99 target ID and electronic pinpoint | The primary reason to choose this model. |
| Main caveat | control box is not submersible | The compromise to accept before ordering. |

Field-use analysis
What actually changes the decision
The useful upgrade over very basic detectors is numerical target ID. It does not identify a coin with certainty, but repeatable numbers plus the five-segment depth scale help a beginner decide what to investigate. The dedicated pinpoint button also shortens recovery once the target has been located.
Its fixed ground balance is the main technical restriction. In ordinary park soil it keeps setup simple; in heavily mineralized ground it removes the user’s ability to tune the machine to the soil. The 8 kHz operating frequency also favors general coin-sized targets over very small low-conductive targets.
The search coil can tolerate water, but the control housing cannot be submerged. That distinction matters around creeks and surf. A newer fully waterproof entry detector is the better purchase when water is part of the plan.
FAQ
Targeted questions answered
Is the Garrett ACE 300 good for a first detector?
Yes for dry-land parks, yards and coin hunting. Its five modes, numerical target ID and pinpoint control are easy to understand, but it leaves less room to handle difficult soil.
Is the ACE 300 waterproof?
The search coil is submersible; the control box is not. Do not lower the display and battery housing into water.
What frequency does the ACE 300 use?
Garrett specifies 8 kHz with frequency adjustment for reducing interference. It is a single-frequency detector.
Can the ACE 300 find gold?
It can detect gold jewelry and sufficiently large nuggets, but it is not a purpose-built prospecting detector and lacks the high frequency and ground controls normally preferred for small natural gold.
Does the ACE 300 have manual ground balance?
No. Ground balance is preset, which simplifies setup but can limit stability and sensitivity in strongly mineralized soil.
What batteries does the ACE 300 use?
It uses four AA batteries. Rechargeable AAs can reduce running cost, but follow the battery maker’s charging instructions.
When should I buy a newer detector instead?
Choose a newer model when you need full waterproofing, simultaneous multi-frequency operation, wireless audio or adjustable ground balance.
