GR3 Plus Deep Seeking 3D Metal Detector - Dual Sensor by Groundtech
The GR-3 PLUS 3D ground scanner is a small, light metal detector that is easy to use to find treasures that are hidden deep. The analysis app, which can be downloaded on both Android and iOS tablets and smartphones, lets you see scan data of the target area in 3D.
The GR-3 PLUS device is a stick-shaped probe that is used to do a ground scan. The measurement data from the ground scan is stored and sent so that it can be seen as 3D graphics through a 3D analysis app. This app gives the prospector detailed tools to look at the data and see all the information about buried treasures, such as the type of metal, its size, and its depth.
All of these great features come with the GR-3 PLUS at a great price. It's perfect for newbie or casual prospectors, and even professional treasure hunters can use it. It's a reliable ground scanner that can be used for any reason.
Features
Multi-Purpose Device
The GR-3 PLUS is a 3D ground scanner metal detector that can do the following:
- Find hidden gold jewels like golden boxes, old coins, and gold jewelry.
- Finding things made of non-ferrous metals, like a silver piece, a bronze statue, or a copper plate.
- Find ferrous metals like iron, steel, and iron alloys.
- Finding holes in the ground, like those in caves, rooms, bunkers, and other places.
3D Ground Scan Technology
The GR-3 PLUS device is a ground scanner tool with sensors built in. It has two high-precision sensor systems, called CN-D Sensors, that let it go deeper into the ground and give the user more accurate high-resolution data for 3D viewing.
Detection Modes
The GR-3 PLUS ground scanner has a lot of different detection modes that can be used for different metal detection tasks. The modes that come with the scanner are:
1 – 3D Ground Scan Mode:
This is the most common sensing method used to scan the ground and see the data through the GR-3 PLUS analysis app. The scan can be done automatically or by hand.
2 – Live Scan Mode:
You can use it to quickly scan an area for possible targets. The scan data is shown in real time as a 2D stream of colors that change depending on the type of target the probe hits.
3 – Pinpointer Mode:
Used to identify possible metal items during digs (usually after ground scan mode has been used to find the target).
3D Analysis App
The GR-3 PLUS 3D ground scanner can show its scanned data visually on any Android or iOS device that supports it, like tablets or smartphones. This is done with the GR-3 PLUS analysis app, which can be downloaded and used to show the scan data as 3D graphics that show the structure of the scanned area and what it contains, like a golden treasure, a tunnel, or just plain ground.
The research app comes with strong tools that can look at that data and give users useful details about hidden targets, like where they are, how deep they are, and what kind of metal they are made of.
Wireless Data Transmission
Using Bluetooth 4.2 BLE technology, the scan data is sent directly to a computer or smartphone, where it can be processed and seen in an analysis app. This technology has a range of about 50 meters.
Rechargeable Battery
