**2. Brief Introduction:**
The HFD-C Multi-Function Natural Electrical Field Detector is a specialized tool designed for detecting underground water at depths of up to 300 meters. It works by measuring the intensity of the natural electrical field and analyzing changes in underground resistivity to determine the location and depth of water.
This device solves a major challenge in natural electric field detection—frequency selection and anti-interference. Its waterproof design and touch screen interface make it user-friendly and easy to operate.
The HFD-C is portable, efficient, and accurate. It supports automatic measurements and provides clear data and curve displays. Compared to traditional DC electrical water detectors, it improves measurement speed by more than 8 times while reducing weight by 8 times. With over 20 years of experience, we have built a strong reputation and are highly praised by our customers.
**3. Comparison with Traditional Geo-Electrical Water Detectors:**
| Traditional Geo-Electric Water Detectors | HFD-C Ground Water Detector |
|------------------------------------------|--------------------------------------------------|
| Heavy, complicated wiring due to manual power supply | No need for power supply; uses natural electric field and 20-meter receiver pole |
| Requires 3–5 people, low efficiency | Only 2 people needed, high efficiency |
| Heavy, 50–500 kg, hard to move | Lightweight, under 5 kg, easy to carry |
| Data must be transferred to PC for analysis | Uses 4G U-disk for data storage, easy to process |
| Professional operation, expensive | Practical and cost-effective |
| Only detects water location and depth | Can detect water location, direction, depth, and flow |
**4. Applications:**
