How to use 3HT2 underground water finding device
The underground water finding device is easy to operate with a fully wireless system. Follow the steps below:
1. Power-on and Connection:
Press the power button located on the top of the device to turn it on. The power button is equipped with an integrated indicator light that displays the device's working status. Using Bluetooth 4.0 technology, the device can be wirelessly connected to a mobile phone, tablet, or dedicated control host. It offers fast data transmission, low latency, and a connection range of over 100 meters.
2. Parameter Setting:
Once the connection is established, quickly adjust the measurement depth via the APP on your mobile phone or other devices. You can select the desired depth range based on your specific requirements.
3. Measurement Operation:
Place the groundwater detection device on the ground in a consistent direction for measurement, or insert it into the soil. After measuring one point, move the device an equal distance to the next location and repeat the process to complete measurements at multiple points.
4. Result Viewing:
After completing the measurements, the APP will generate on-site two-dimensional, three-dimensional, and curve effect diagrams of the underground environment. These diagrams allow you to identify the location and depth of groundwater, as well as estimate the water volume.




Case Study: Water Detection Using Underground Water Finding Device
Water Finding in the Xixiangtang Limestone Area, Nanning
-
Background:
In the Xixiangtang limestone area of Nanning, the 3HT2 underground water finding device was used for water prospecting. The region is characterized by limestone formations, primarily composed of calcium carbonate, which is highly soluble and leads to the development of karst landscapes such as stone forests and caves.
-
Measurement and Results:
On-site real-time measurements identified the optimal drilling location around point 100. During the drilling process, water began to emerge at approximately 30 meters, with an initial flow rate of about 20 tons per hour. As drilling progressed to around 110 meters, the water yield gradually increased, reaching a total of 80 tons per hour upon well completion.
This case demonstrates the high accuracy and efficiency of the underground water finding device in complex limestone formations.
