What Are Different Imaging Modes on Metal Detectors?


Imaging Modes on Metal Detectors
Imaging Modes on Metal Detectors

There are several key points to understand about underground imaging technology offered by various devices in the market:

  • Most devices offer a Basic scanning mode, where the user is required to move the detector in a zig-zag or parallel scanning direction to create a ground scan.

  • In Basic scanning mode, the location of the taken measurement is not precise, resulting in lower accuracy and resolution of the 3D ground scan.

  • TreasureHunter3D devices are capable of taking measurements at exact locations, providing the best scan resolution possible, and setting them apart in the market.

  • The GoldenEye+ model is the first metal detector 3D ground scanner using augmented reality technology, enabling the device to display ground scan results on a smartphone in real time and mapped on a real-world environment.





In this blog, we will compare basic scanning, which is offered by most devices in the market, with TreasureHunter3D Advanced and Professional 3D ground scan technologies.



Basic 3D ground scan Imaging Mode


How does basic 3D ground scan Imaging mode work?

In the basic 3D ground scan mode, the user must scan the area with parallel lines or a zig-zag pattern, moving the device precisely at a constant speed. The device relies on the user to carefully move the device, and the accuracy and resolution are not optimal.

Pros:

  • it is most affordable since most of the devices on the market today provide basic 3d scan

  • scan results can be observed in real-time, but cannot be mapped in the real-world environment


Cons:

  • Cannot provide high-resolution 3D ground image.

  • The user experience is not great since the user must move the device carefully in a specific motion.

  • Users cannot freely walk around during scanning.








Advanced 3D ground scan


How does advanced 3D ground scan mode work?


In the advanced 3D ground scan mode, available for the Golden Eye treasure detector, users can place a tag on the floor at the scan area location, providing a device reference point for exact location understanding. This mode can provide a higher-resolution image of the target object and allows the user to freely move the device during scanning.

Pros:

  • Provides a higher-resolution image of the target object.

  • Users can freely move the device during scanning.

  • The device provides error correction logic to ignore false sensor readings.


Cons:

  • For larger areas, the user must still use the basic scanning mode.

  • It doesn't work well in the dark.







Professional 3D ground scan


How does Professional 3D ground scan mode work?


In the professional 3D ground scan mode, available for the Golden Eye Plus treasure detector, users can freely move around during scanning, observe scan results on a smartphone, and map in a real-time environment. This mode also doesn’t require the use of a tag and provides the best possible user experience.



Proffesional Imaging Mode

Pros:

  • Scan results can be observed in real-time and mapped on a real-time environment.

  • Scan accuracy and resolution are 160 times better than the basic one and the most accurate possible.

  • Users can scan small or very large areas by just freely walking around.


Cons:

  • scanning may slow down in dark light conditions







Conclusion

In conclusion, while basic 3D ground scan mode is affordable and provides real-time results, advanced and professional 3D ground scan modes offer higher resolution, better user experience, and the ability to freely move during scanning, making them suitable for more advanced and professional applications.
