Great 4-S

The Great 4-S is an innovative device that incorporates the latest hardware technology. It works with four search systems and can detect gold and buried treasures to a depth of up to 25 meters underground, while it works within a range of 3000 meters. The Great 4-S gold detector is designed to detect a variety of buried targets including gold minerals, precious metals, diamonds, gemstones, voids, and caves.

To use the Great 4-S, the operator needs to be familiar with the machine’s various features and settings. The instrument must first be calibrated according to the area of interest, and the operator needs to ensure that they have the correct search coil for the task at hand. The device will identify targets by giving an audio and visual alert through the device’s LCD screen. Once the target has been located, the operator then will need to dig fully to retrieve the target. The Great 4-S is suitable for use by both novice and experienced users seeking to find buried treasure or metal.

Device Features

4 Search Systems

• 3D ground scanning
• Metal discrimination system
• Direct horizontal imaging system
• Direct vertical imaging system

3D Scanning System

Run the tab and open the program. Open the device from the file. Select the device type Great 4S. Choose the correct COM type. Choose the type of connection, then choose the cable. Then press the OK button. Check the number of shots. Then make sure the device is 5 to 10 cm above the ground and take shots after each distance of half a square or square meter, depending on the appropriate place which is searched. Once completed, store the image and then enhance the shape in the ground and determine the type of metal or the shape of the void and its depth in centimeters.

Color indications: The red color indicates gold. The yellow color indicates the presence of minerals. The blue color indicates a void. Green indicates other materials.

Mineral Discrimination System

This system distinguishes between metals, gold, precious metals, and voids.

How the metal discrimination system works: Change the system from the open program file. Select the Great 4S device type. Choose the correct COM type. Select the connection type and select the cable. Determine the type of metal discrimination. Then press the OK button. Then point the device at the ground and make sure the device is elevated. Move the device from 5 to 10 cm from right to left to distinguish the target in the ground.

Color indications: The red color indicates gold. The yellow color indicates the presence of minerals. The blue color indicates a void. Green indicates other materials.

Direct Horizontal Imaging System

This system is characterized by directly searching behind walls, doors, or rocks.

How the horizontal imaging system works: Change the system from the program. Open from file. Select the type of Great 4S device. Choose the correct COM type. Choose the type of connection, then choose the cable. Determine the type of direct horizontal shooting. Then press the OK button. Place the device. Move the device from right to left in a straight line. The display will show yellow or orange for precious metals, gray with green for concrete in different shapes depending on the target.

Direct Vertical Imaging System

This system is a direct vertical imaging system used to search for objects on the ground. It is known for its ability to quickly search and shoot straight. To use the system, one needs to select the correct device type and COM type, followed by selecting the connection type and cable. Once this is done, the user can select the type of direct vertical shooting and press the OK button. The device must be placed at a height of 5 to 10 cm and moved to obtain results.

Color indications: Red indicates that the target has been detected. Yellow or orange represents precious metal. Blue indicates a void. This system is practical for direct vertical searching.
