Metal Detector Number Chart Basics

Metal detector number charts are essential tools for treasure hunters and metal detecting enthusiasts. They provide a visual representation of the different types of metals that a metal detector can identify, along with their corresponding numerical values. This information can be used to quickly and easily identify the type of metal that has been detected, making it easier to decide whether or not to dig it up.
There are several different types of metal detector number charts available, each with its own unique set of features. Some charts are designed for specific types of metal detectors, while others are more general-purpose. It is important to choose a chart that is compatible with your metal detector and that meets your specific needs.
Using a Metal Detector Number Chart
Using a metal detector number chart is relatively simple. Once you have selected a chart, simply compare the number that is displayed on the metal detector's display to the numbers on the chart. The corresponding metal type will be listed next to the number.
For example, if your metal detector displays a number of 20, you would look for the number 20 on the chart. The corresponding metal type would be listed next to the number, which in this case would be "gold".
Metal detector number charts are a valuable tool for treasure hunters and metal detecting enthusiasts. They can help you to quickly and easily identify the type of metal that has been detected, making it easier to decide whether or not to dig it up.
Interpreting Metal Detector Numbers: Metal Detector Number Chart

Understanding the numeric values displayed on a metal detector is crucial for accurate target identification. These numbers represent the electrical conductivity of the detected object, which varies depending on its metal composition.
Different metal types correspond to specific ranges of numbers. For instance, iron objects typically fall within the lower number range, while gold and silver tend to be in the higher range. However, it's important to note that these ranges can vary depending on the specific metal detector model and environmental conditions.
Interpreting Numbers Accurately
To interpret the numbers accurately, consider the following factors:
- Ground mineralization: Soil conditions can affect the detector's readings, potentially masking or enhancing the target signal.
- Target size and shape: Larger and irregularly shaped objects can produce more complex signals, making identification more challenging.
- Detector settings: Sensitivity, discrimination, and other settings can influence the numeric values displayed.
By understanding these factors and correlating the numeric values with known metal properties, you can enhance your ability to identify targets accurately with your metal detector.
Creating Custom Metal Detector Number Charts
Customizing metal detector number charts is essential for optimizing performance in specific soil conditions and target metal types. By calibrating your detector and adjusting the chart, you can enhance accuracy and effectiveness.
Calibrating Your Metal Detector
To create a custom number chart, start by calibrating your detector. This involves adjusting the sensitivity and discrimination settings to suit the soil conditions and target metals. Use a test plot with known metal objects to fine-tune the settings.
Optimizing the Number Chart
Once your detector is calibrated, you can optimize the number chart by assigning specific numbers to different target metals. This can be done through experimentation and field testing. Note the numbers that correspond to different metals and adjust the chart accordingly.
Tips for Maximizing Accuracy
- Use a clean test plot with known metal objects.
- Calibrate your detector regularly, especially when changing soil conditions.
- Assign specific numbers to each target metal based on field testing.
- Test your custom chart in different soil types to ensure accuracy.
- Make adjustments to the chart as needed to improve performance.
Advanced Applications of Metal Detector Number Charts
![]()
Metal detector number charts are valuable tools that can be used in a variety of advanced metal detecting techniques. These techniques can help you to discriminate between different types of metal objects, identify specific targets, and locate buried treasure.
One of the most common uses for metal detector number charts is in discrimination mode. This mode allows you to set your metal detector to ignore certain types of metal, such as iron. This can be helpful in areas where there is a lot of iron trash, such as in parks or on beaches.
Another use for metal detector number charts is in target identification mode. This mode allows you to identify the type of metal object that you have found. This can be helpful in determining whether or not an object is worth digging up.
Finally, metal detector number charts can be used to locate buried treasure. By using a number chart, you can track the location of metal objects that you have found. This can help you to narrow down the search area and find the treasure.
Discrimination
Discrimination is a metal detecting technique that allows you to ignore certain types of metal. This can be helpful in areas where there is a lot of iron trash, such as in parks or on beaches.
To use discrimination, you will need to set your metal detector to the discrimination mode. This mode will allow you to set the metal detector to ignore certain types of metal, such as iron.
Once you have set the metal detector to the discrimination mode, you can start searching for metal objects. When the metal detector detects a metal object, it will produce a sound. The sound will be different depending on the type of metal that the metal detector has detected.
If you hear a sound that indicates that the metal detector has detected iron, you can simply ignore the object. However, if you hear a sound that indicates that the metal detector has detected a different type of metal, you may want to dig up the object to see what it is.
Target Identification
Target identification is a metal detecting technique that allows you to identify the type of metal object that you have found. This can be helpful in determining whether or not an object is worth digging up.
To use target identification, you will need to set your metal detector to the target identification mode. This mode will allow you to identify the type of metal object that the metal detector has detected.
Once you have set the metal detector to the target identification mode, you can start searching for metal objects. When the metal detector detects a metal object, it will produce a sound. The sound will be different depending on the type of metal that the metal detector has detected.
The metal detector will also display a number on the screen. This number will correspond to the type of metal that the metal detector has detected.
You can use a metal detector number chart to identify the type of metal that the metal detector has detected. The number chart will tell you the type of metal that corresponds to each number.
Locating Buried Treasure
Metal detector number charts can be used to locate buried treasure. By using a number chart, you can track the location of metal objects that you have found. This can help you to narrow down the search area and find the treasure.
To use a metal detector number chart to locate buried treasure, you will need to first create a grid of the search area. Once you have created the grid, you can start searching for metal objects.
When you find a metal object, mark the location on the grid. You can also use the metal detector number chart to identify the type of metal that the metal detector has detected.
Once you have marked all of the locations of the metal objects that you have found, you can start to narrow down the search area. You can do this by drawing lines between the locations of the metal objects.
The intersection of the lines will be the location of the buried treasure.
Troubleshooting Metal Detector Number Charts

Metal detector number charts are valuable tools for identifying and categorizing metal objects. However, several factors can affect their accuracy. Understanding these issues and implementing effective troubleshooting measures is crucial for ensuring optimal performance.
Common Issues Affecting Accuracy
* Environmental Interference: Electromagnetic fields from power lines, electrical devices, and other metal objects can interfere with metal detector signals, resulting in false readings.
* Ground Mineralization: Minerals in the soil can mask metal signals, making it difficult to distinguish between targets.
* Target Depth: The depth of the target can impact the strength and accuracy of the signal.
* Detector Sensitivity: Improperly adjusted sensitivity settings can lead to missed targets or false positives.
* Coil Damage: Damaged coils can produce inaccurate or erratic readings.
