GR-3 PLUS 3D ground scanner is a small-size lightweight metal detector, easy to use

to find deep buried treasures with 3D visualization of scan data of target area via

analysis app that can be installed on both Android or iOS tablets and smartphones.

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 stored and transmitted to be visualized

as 3D graphics via 3D analysis app that gives the prospector with 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 GR-3 PLUS comes also at great price tag that fit all beginner

or amateur  prospectors , but even can be used by professional treasure hunters and

deliver reliable ground scanner for all purposes.


GR-3 PLUS Features

Multi-Purpose Device

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 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 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 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 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 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 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 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 PLUS powered using built-in 3.7 Volt lithium-ion (Li-ion) rechargeable battery, it can be charged with
