CONRAD GR-3 PLUS
CONRAD GR-3 PLUS is a small-size lightweight metal detector, easy to use To find deeply buried treasures with 3D visualization of scan data of target area via analysis app that can be installed on Android or iOS tablets and smartphones.
CONRAD GR-3 PLUS Device was designed in the form of a stick-shaped probe that is used to conduct a ground scan, and the ground scan measurement data is stored and transmitted to be visualized as 3D graphics via a 3D analysis app that gives the prospector detailed tools to analyze the Data and know all details about buried treasures like metal type, size and depth visually.
All these great features included in CONRAD GR-3 PLUS also come at a great price tag that fits all beginner or amateur prospectors, but even can be used by professional treasure hunters and deliver reliable ground scanners for all purposes.
Device Details
CONRAD GR-3 PLUS FEATURES
Multi-Purpose Device
CONRAD GR-3 PLUS 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 metal objects such as silver coins, bronze statues, and plates of copper.
- Ferrous metal detection: iron, steel, iron alloys
- Underground cavities detection such as tunnels, chambers, bunkers, and so on
CONRAD GR-3 PLUS Technology
CONRAD GR-3 PLUS Device is basically a ground scanner probe with built-in sensors, it incorporates 2 high precision (dual)
sensor system called CN-D Sensor that enables to penetrate ground layers to reach greater depth and gives the user
more accurate high-resolution data for 3D visualization.
Detection Modes
GR-3 PLUS 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 PLUS analysis app,
the scan process can be conducted either in Automatic or Manual modes.
2 – Live Scan Mode:
Used for a quick scan of the area to find possible targets, it visualizes the scan data in real-time as a 2D colored stream
of colors that change based on the target type that the probe passes over.
3 – Pinpointer Mode:
Used for pinpointing to find possible metal objects during excavations (usually after using ground scan mode to detect the target)
3D Analysis App
GR-3 PLUS 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 PLUS analysis app that can be installed
to show the scan data as 3D graphics that represent the structure of the scanned area and what it contains possible
targets like golden treasure or tunnel or normal ground.
The analysis app is bundled with powerful tools to analyze that data to give users useful information about buried
targets such as position, depth, and metal type.

Wireless Data Transmission
The scan data is transmitted wirelessly to the tablet or smartphone to be processed and visualized inside the analysis app
using Bluetooth 4.2 BLE technology that offers about a 50-meter coverage range.
Rechargeable Battery
CONRAD GR-3 PLUS is powered using a 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.

- User's Guide
Discovery device displays results directly on its screen without the need for a computer, laptop, tablet / tablet / smart phone, etc.
The screen allows you to display results in a graphical three-dimensional form, with the ability to control the width and projections of view, and conduct detailed and accurate analyzes to know the depth, shape and all information about buried targets.
3D graphics
Results can be obtained quickly with the representation of the surveyed land in the form of easy - to-understand 3D graphics that include areas colored in different colors depending on the target, such as blue for spaces, yellow for ferrous metals , red for gold, and so on.
Easily analyze data
The results are displayed in three-dimensional form, and the width and viewpoints can be controlled, and detailed analysis are conducted directly on the screen via the control buttons. The various options for the device program allow accurate analyzes in terms of displaying different projections to clarify the target’s shape, position, depth and geometric shape ... etc.
Great search depths
It can be done under ideal conditions depending on soil structure, type, and size of buried targets
Reaching very large depths, which may reach 25 meters underground, means getting depths much further than those that can be achieved with standard metal detectors.
Detect blanks
Using an innovative hybrid technology based on a geological - electrical system
It relates to measuring the resistance of the soil with the features of a photogrammetry. Voids can be detected
The large undergrounds are like tunnels dug, buried canyons, ancient tombs, and caves
At much more depths compared to similar devices.
Easy, customizable software - available in multiple languages
For the user, the Discovery device software includes a wide variety of customization options
It includes, for example, the display language, display method, units of measurement used, and location information
And customizing the time zone, screen brightness, and other options.
Languages available
English - German - Spanish - Italian - French - Turkish - Russian - Chinese - Arabic - Persian language
