A New Way to Dive Deep

GR-3 Plus

GR-3 Plus; is a ground scanning detector that detects differences under the ground and allows you to make 3D analysis. It enables you to detect, measure, and locate buried metals, magnetic objects, and cavities such as tombs, rooms, tunnels. It graphically displays magnetic (iron or steel) and non-magnetic (gold, silver or copper) metals through its specially developed 3D analysis software.

The specially designed 3D Analysis software graphically displays magnetic (iron or steel) and non-magnetic (gold, silver or copper) metals.

Depending on the size (diameter) of the target and the soil structure, depths of up to 10 meters (with GR -3 10 meters and with GR -3 Plus 15 meters) can be reached.

GR-3 Plus – Package Content

Device main unit, 5 Volt charging adapter and charging cable, Case, User manual, Warranty certificate

The GR-3 is designed to be extremely simple and compact, making it accessible to everyone.

It does not have any cables or heavy batteries. Thanks to its lightweight design, the user scans the ground and the data received during the scan is displayed on the screen of a mobile device such as a tablet or phone in real-time.

The results on the screen can be analyzed immediately after the scanning and measuring process is finished. The data received can be stored on your mobile device such as a tablet or phone and can be re-evaluated in detail when needed.

The depth and diameter (size) of the target (metal and/or cavity) can be quickly determined thanks to the software's options.

The GR-3 is a multi-purpose device that can be used in all types of terrain (sandy, rocky or clayey).

GR-3 is available in two different models;

GR-3 model has a

high precision single sensor system

The GR-3 Plus model has a

  1. Wireless data transfer
  2. 3D Analysis app specially developed for Android and IOS
  3. Automatic and Manual, 3D ground scanning function
