Tianxun TX-850 Key Features Overview
Based on available product information, the TX-850 commonly includes features such as:
| Feature | Description |
|---|---|
| Detection Type | Ground metal detector |
| Display | LCD screen |
| Search Coil | 11-inch DD waterproof coil |
| Frequency | Around 19 kHz |
| Detection Modes | LCD and audio indication |
| Adjustment | Sensitivity and ground balance |
| Power Supply | 9V battery |
| Design | Adjustable shaft and portable structure |
The combination of digital display, adjustable sensitivity, and ground balance functions makes it more flexible compared with simple beginner detectors.
How Does Tianxun TX-850 Work?
Understanding the technology helps users know what this detector can realistically do.
1. Electromagnetic Signal Transmission
The search coil creates an electromagnetic field.
When the detector passes over a metal object, the target creates a response signal.
The detector analyzes this response and produces:
- Sound alerts
- Digital information
- Target indication
2. Target Identification
The LCD display helps users understand detected signals.
Depending on settings and conditions, users can distinguish possible:
- Coins
- Jewelry
- Iron objects
- Other metals
3. Ground Balance Technology
Soil conditions can affect metal detection performance.
Mineralized soil may create unwanted signals.
Ground balance helps reduce interference and improve stability.
This feature is especially useful in:
- Dry areas
- Rocky terrain
- Mineralized ground
Tianxun TX-850 Performance Review
1. Detection Sensitivity
One advantage of the TX-850 is adjustable sensitivity.
Users can increase sensitivity when searching for smaller targets.
However:
Higher sensitivity does not always mean better results.
In difficult environments, excessive sensitivity may create false signals.
The best approach is adjusting settings according to:
- Soil condition
- Target type
- Search environment
2. Detection Depth Performance
A common question is:
How Deep Can Tianxun TX-850 Detect?
The answer depends on:
- Target size
- Metal type
- Soil condition
- Search coil
- Detector settings
Large metal objects can usually be detected deeper than small objects.
Manufacturers and sellers publish different maximum depth values under different test conditions, so users should treat depth numbers as reference values rather than guaranteed field performance.
3. Search Coil Performance
The TX-850 commonly uses an 11-inch DD search coil.
Advantages of DD coils:
- Better ground coverage
- Improved stability
- Suitable for outdoor searching
A larger coil can help cover more ground, while smaller coils may provide better target separation in areas with many objects.
Testing Tianxun TX-850 in Different Environments
Beach Searching
Suitable for:
- Coins
- Jewelry
- Lost metal objects
Important factors:
- Ground balance adjustment
- Saltwater interference control
Fields and Forest Areas
Good applications:
- Historical relic searching
- Coin hunting
- General exploration
Gold Prospecting Areas
The TX-850 can detect metal targets including gold objects.
However, users should understand:
Natural gold nugget hunting usually requires detectors specifically optimized for gold prospecting, especially in highly mineralized environments.
For serious gold mining applications, professional Pulse Induction (PI) gold detectors may provide better performance.
