If you are looking for a metal detector that is one step up from an entry-level machine then the Ace 300 is for you. It’s an affordable detector that has all the right settings to help you find more coins, jewelry, and relics that have been lost in the ground.

Top Features

The Ace 300 has some features not always found in metal detectors of the same price level. All these features come in handy when it comes to finding the treasure you are searching for. So the following are the top features that will help you in your metal detecting adventures.

Top Ace 300 metal detector features.

Adjustable Frequency

When detecting in groups where there are other metal detectors around or a lot of electrical interference the being able to adjust the frequency of your metal detector is crucial to your success.

The Ace 300 allows you to do just that.

Digital Target ID

The digital target ID helps you identify what type of metal you are detecting based on the conductivity of the target. You get a digital reading 0-99 of the target that displays on the front of the control panel.

If the target you are detecting is highly conductive like silver, copper or gold the scale will read in the higher numbers such as the 80s or 90s. Iron because of it’s low conductivity will ring anywhere from 0-30 on the digital scale.

For best results using the target id, you will want to center the target under the search coil and sweep flat keeping the search coil at the same height at all times.

Electronic Pinpointing

Finding the precise location of your target has never been easier with the electronic pinpointing setting that you get on the Ace 300. It’s a non-motion all-metal pinpointer built right into the search coil.

Iron Check

If you are detecting in an area littered with iron trash just switch on the iron check function and you will get enhanced iron discrimination that will help you find the treasure beyond the junk that might be buried alongside the treasure.

Graphic Target Analysing

This setting shows the conductivity of the target along with the discrimination pattern that accompanies the target. This gives you a clearer picture of what your target is.

Get to Know Your Machine

Garrett Ace 300

Before you take your metal detector out in the field do some bench testing first so you can get to know how your detector responds to different objects and types of metal. Here’s how you can conduct a bench test.

  1. Lay the metal detector on a table or flat surface with the search coil laying on its side. Make sure there are no metallic objects laying nearby.
  2. Select mode to Zero-Disc.
  3. Put various objects like different size coins, bottle caps, nails, etc. about 4 inches in front of the search coil. The metal detector will identify these targets using audio and visual signals.
  4. Repeat this test in all modes making note of the different sounds and visual cues the metal detector gives off. This will help you learn what you need to look and listen for when detecting a number of different targets in different modes.
  5. Write down the results of the tests and use them as notes when you are in the field.

Test on Sand and Loose Soil First

After you perform your bench test you are ready to take the detector out in the field for real-world treasure hunting. But first, test your detector on sandy or loose soil so you can get a feel for how things work. This makes it easier to learn how to pinpoint targets and dig.

For best results keep your search coil about one inch above the ground keeping it level with the ground. Keep the coil parallel with the water edge if you are detecting on a beach and at any time go with the natural lay of the land. By doing this you will get the most accurate performance of your machine.

Final Thoughts

Well, there you have it the Garrett Ace 300 review. All in all, it’s an excellent metal detector especially for beginner detectorists, and it won’t break the bank. Every feature necessary to start metal detecting is on this machine so you won’t have any trouble finding that elusive treasure buried under your feet.

It’s a great metal detector for detecting a range of objects like coins, relics, and jewelry. If I had to pick one of the best metal detectors to start with it the Ace 300 would be at the top of my list. Garrett is a top-notch company that knows what they are doing when it comes to manufacturing metal detectors. You can count on them to deliver a quality product for an affordable price.
