**Introduction:**
The HFD-C Multi-Function Natural Electrical Field Detector is specifically designed for deep underground water detection. It measures the natural electrical field to monitor changes in underground resistivity, helping identify the location and depth of water sources. This instrument overcomes challenges such as frequency selection and interference in natural electric fields, offering a reliable and efficient solution for geophysical surveys.
**Advantages Over Traditional Detectors:**
- **No need for external power supply** – uses the natural electric field and a 20-meter receiver pole.
- **Lightweight and portable** – only 2.3kg, easy to carry and operate.
- **Fast and accurate** – reduces measurement time by 8 times and improves accuracy.
- **User-friendly** – simple operation with a touch screen interface.
- **Cost-effective** – no need for complex software or professional operators.
- **Comprehensive data analysis** – provides information on water location, direction, depth, and flow.
**Applications:**
- Metal and non-metal ore exploration
- Underground water detection in various geological conditions
- Drinking water, industrial, and agricultural irrigation
- Engineering and disaster geological surveys
- Coal goaf, archaeological mining, city exploration, and non-metallic pipeline survey
**Why Choose HFD-C?**
- **Aluminum alloy case** – durable and easy to transport.
- **Built-in lithium battery** – fast charging (4 hours) and long usage (16 hours).
- **Special electrodes** – improve speed and precision during rough and fine measurements.
- **Multiple anti-jamming designs** – ensure stable and accurate data collection.
This advanced detector combines technology and practicality, making it an essential tool for modern geophysical exploration. Whether you're working in remote areas or urban environments, the HFD-C delivers powerful performance and ease of use.
