Ground balancing neutralizes the effects of ground mineralization. On models like the TX-850, turn the Ground Balance knob until the detector stabilizes and emits a minimal hum regardless of lifting or lowering the coil.
The discrimination setting allows you to filter out specific types of metals, such as trash iron or foil, so the detector only alerts you to valuable targets like coins or gold.
Constant noise or falsing can be caused by electromagnetic interference from power lines, high mineralization in the ground, or sensitivity set too high. Try lowering the sensitivity (Gain) or adjusting the ground balance.
Yes, most Tianxun search coils (like those on the TX-850 and MD-6450) are waterproof and can be submerged in shallow water. However, the control box is usually not waterproof and must be kept dry.
Most Tianxun hobby detectors use either one or two 9V alkaline batteries. Always check your specific user manual or the battery compartment markings for the correct voltage.
