GR-3 Features
Multi-Purpose Device
GR-3 is a 3D ground scanner metal detector that can be used to:
- Find buried gold treasures such as: golden chests, ancient coins, golden jewelry.
- Detection of Non-Ferrous metals objects such as silver coin, bronze statue, plate of copper.
- Ferrous metal detection: iron, steel, iron alloys.
- Underground cavities detection such as : tunnels, chambers, bunkers and so on.
3D Ground Scan Technology
GR-3 device is basically a ground scanner probe with built-in sensors, it incorporates 2 high precision (dual) sensor system called CN-D Sensor that enable to penetrate ground layers to reach greater depth and gives the user more accurate high-resolution data for 3D visualization.
Detection Modes
GR-3 ground scanner has many different detection modes that fit particular metal detection applications, the included detection modes are:
1 – 3D Ground Scan Mode:
It is the most used detection mode used to scan the ground and visualize the data via GR-3 analysis app, the scan process can be conducted either in Automatic or Manual modes.
2 – Live Scan Mode:
Used for quick scan of area to find possible targets, it visualize the scan data in real time as 2D colored stream of colors that change based on the target type that the probe pass over.
3 – Pinpointer Mode:
Used for pinpoint to find possible metal objects during excavations (usually after using ground scan mode to detect the target).
3D Analysis App
GR-3 3D ground scanner can display its scanned data visually on any supported Android or iOS devices such as tablets or smartphones, and that done using GR-3 analysis app that can be installed to show the scan data as 3D graphics that represent structure of scanned area and what it contains of possible targets like golden treasure or tunnel or normal ground.
The analysis app is bundled with powerful tools to analyze that data to give user useful information about buried targets such as position, depth and metal type.
Wireless Data Transmission
The scan data transmitted wirelessly to the tablet or smartphone to be processed and visualized inside analysis app using Bluetooth 4.2 BLE technology that offer about 50 meter coverage range.
Rechargeable Battery
GR-3 powered using built-in 3.7 Volt lithium-ion (Li-ion) rechargeable battery, it can be charged with 5 volt Micro-USB or charging with portable power sources like power-banks.
*Depth values vary according to soil type and the size of the buried object. The values given are maximum values.

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.
