GREAT 2S - 3D Metal Detector

Frequently Asked Questions (FAQ)

What is the detection depth of your metal detectors?
Our metal detectors vary in detection depth depending on the model and the type of metal being detected. Generally, our detectors can identify targets at depths ranging from a few inches to several feet. For specific models, please refer to the product specifications on our website.

Can I test my metal detector with freshly buried metals?
Freshly buried metals cannot be detected immediately. For a metal detector to sense the buried metal, it needs to disrupt the magnetic field, which requires the metal to remain underground for a certain amount of time.

What is the detection distance of your professional metal detectors?
Professional metal detectors locate metals buried for many years by detecting subtle environmental changes caused by these metals. They utilize bio-energy interaction, ionization technology, electromagnetic field detection, advanced microprocessor analysis, long-term soil disturbance detection, and sensor fusion. The longer the burial time, the easier it is to detect these metals due to more pronounced ion fields and electromagnetic signatures.

What factors affect detection capability?
Several factors can influence detection capability, including:
● Soil Conditions: Mineralization levels and moisture can impact performance.
● Target Size: Larger targets are typically detected at greater depths than smaller ones.
● Detector Settings: Adjusting sensitivity and discrimination can help optimize detection.

What are some practical testing methods for professional metal detectors?
● Field Testing in Historic Sites: Test in areas with known buried metal objects, like historical battlefields or archaeological sites (with permission).
● Using Known Buried Objects: Test in places where long-buried metals are documented, such as old farm fields or construction sites.
● Avoid Air Testing: Do not test with unburied or freshly buried metals. These detectors work by detecting ionization fields around long-buried metals, unlike hobby detectors.
● Avoid Testing Inside Structures: Testing indoors can lead to interference from numerous cables, electrical systems, and other factors that can affect the performance of professional detectors.

How do I maintain my metal detector?
To keep your metal detector in top shape:
● Clean After Use: Remove dirt and moisture from the detector, especially the coil.
● Store Properly: Keep it in a cool, dry place and avoid extreme temperatures.
● Check Batteries: Regularly check and replace batteries to ensure optimal performance.

Can I use my metal detector into the water?
Some of our metal detectors are designed for water use, while others are not. Always check the product specifications to see if your model is waterproof or submersible before using it in water.

What should I do if my metal detector isn't working properly?
If your metal detector isn't working, please follow these steps:
● Send Us a Video: First, send us a video demonstrating how you are using the detector. In 95% of cases, the issue is due to user error.
● Technical Review: Our technical team and the manufacturer will review the video to determine the cause of the issue.
● Next Steps: Based on their assessment, we will provide a solution, which may include fixing the device, replacing it, or confirming that it’s a user error.
