Top Features of the Garrett AT Gold

Garrett AT Gold features
The AT Gold has many features that come in handy when metal detecting. There is a bit of a learning curve. So make sure you read the owner’s manual and watch some of Garrett’s instructional videos so that you can familiarize yourself with the product.
The best way to learn your machine is to get out in the field and try all the features out. Listening to the tones and beeps it makes with different types of metal.
You can test the machine out by placing the detector on a flat surface. Place different types of metal in front of the search coil and listen to what you hear for each type of metal. Play around with different settings. Make sure to take notes of what you hear in various settings and situations with the metal objects.
The following are some of the AT Golds’ top features.

Proportional Audio

Proportional audio allows you to tell which targets that are close to one another or treasure that’s buried amongst a lot of trash. You will hear faint signals if the target is small and deep in the ground. And louder signals the bigger and closer to the surface the target is.
If there are two targets at the same depth but they are different sizes you will hear a fainter signal for the smaller target. You will hear a louder signal for the larger targets. This allows for the faster recovery time of the targets even when they are close to one another.

Iron Audio

The iron audio feature can be switched on in two different modes:
  • Disc Mode
  • All Metal Mode
When there is a lot of iron objects in the ground you can get false readings on your metal detector or no signal at all. With iron audio in disc mode, you can hear iron signals which you normally wouldn’t hear without it.
This helps you get a bigger picture of what’s buried beneath. This way you know the good and bad targets before you dig them up.
Iron audio in all-metal mode is used for telling if a target is made of iron. It’s not recommended to have iron audio always switched on just when you are checking for the iron content of the target.

Adjustable Threshold

This feature lets you manually adjust the audio so you can tune out unwanted humming or interference noises. This helps you hear the distinct tones of the metal detector more easily.

Adjustable Frequency

The AT Gold has four different frequencies that you can adjust. This allows you to avoid interference with electric sources that may be close by. It also helps to reduce interference from other metal detectors that might be in the area.
To check the frequency push the FREQ button once. If you press it twice you can change between settings. The different frequencies are so slight that it won’t affect the target detection of the machine.

Fast Track and Manual Ground Balance

Grounding your machine is important especially if the ground in of various mineral types. With the AT Gold, you can either fast track the ground balance which the machine will automatically do for you or you can do it manually.
If you read the owners manually it shows you how to do both.

Electronic Pinpointing

The pinpointing feature comes in handy when you want to precisely locate the target you have detected. Hold the pinpointing button down while moving the search coil back and forth and side to side. Make sure to keep the search coil at a constant height above the target this will help avoid false signals.
You can also watch the bar graph of the screen the higher up the scale on the bar graph the stronger the signal. Once the target is pinpointed the symbol PP will show up on the scale meaning the target has been pinpointed.

All Metal Mode

In the all-metal mode, you will hear everything that is in the ground. It is important when detecting in this mode that the AT Gold is properly ground balanced so that you hear the right signals and don’t get false positives.
With this mode, you get the greatest possible depth and sensitivity. This is why gold prospectors love the all metals mode. If there are gold nuggets in the ground you will find them in this mode.
All ground minerals must be canceled out in order to hear just the metal targets in the ground.

Gold Prospecting with the AT Gold

One of the things I love about this metal detector is that you can take it prospecting with you. It makes gold prospecting easy because you can submerse this detector in water and detect for the presence of gold before you even start panning for it!
That alone will save you a lot of time because when you start panning you know that there will be gold when you are done at the bottom of your gold pan! Now if that doesn’t get you excited I don’t know what will.
You can also use the AT Gold to find gold veins and deposits that are at the bottom of rivers and streams. This is possible because this machine is waterproof up to 10 feet of freshwater. It’s not recommended for use in saltwater. The minerals in salt will interfere with the readings causing false positives
But you can use the AT Gold on dry sand beaches for searching for coins and jewelry.
