探测学院
通过清晰的互动课程，理解金属探测器的真正工作原理。点击、对比、观看每一个概念生动呈现——从阈值、辨别到消噪与多频技术——让每一个信号都更易理解。
Threshold
The faint background hum that lets you hear the smallest, deepest targets.
Discrimination
How a detector tells good targets from trash by reading conductivity.
Noise Cancel
Shifting frequency to silence electrical interference (EMI) for a stable, quiet signal.
Multi-Frequency
Running several frequencies at once for better depth and target ID across changing soils.
Recovery Speed
How fast a detector resets between targets — the key to not missing finds in trashy ground.
