Detecting Academy
Explore clear, interactive lessons that explain how metal detectors really work. Tap, compare, and watch each concept come to life — from threshold and discrimination to noise cancel and multi-frequency technology — so every signal becomes easier to understand.
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.
