2. **Brief Introduction:**
The HFD-C Multi-Function Natural Electrical Field Detector is a specialized water detection device designed for depths up to 300 meters. It measures the intensity of the natural electrical field to monitor changes in underground electrical resistivity, allowing for accurate analysis of the location and depth of underground water sources. This instrument solves key challenges such as frequency selection and anti-jamming in natural electric fields. Its waterproof casing and touch screen make it user-friendly and easy to operate.
The HFD-C is portable, efficient, and easy to use. It offers clear and simple data display and curve drawing. Compared to traditional DC electrical water detectors, it increases measurement speed by over 8 times while reducing the weight by 8 times. With over 20 years of experience, we have built a strong reputation and received high praise from our customers.
3. **Comparison with Traditional Geo-Electrical Water Detectors:**
| Traditional Geo-Electrical Water Detectors | HFD-C Groundwater Detector |
|---------------------------------------------|----------------------------|
| Heavy equipment, complex wiring due to manual power supply | No need for power supply; uses natural electric field and 20m receiver pole |
| Requires 3–5 people, low efficiency | Only 2 people needed, high efficiency |
| Heavy, 50–500kg, hard to move | Lightweight, <5kg, easy to carry |
| Data must be transferred to PC and analyzed using software | Uses a 4G U-disk for storage and allows direct data operations |
| Professional operation, expensive | Practical and cost-effective |
| Only identifies water location and depth | Can identify water location, direction, depth, and flow |
