Metal detector with low frequency afford Deeper through Into the ground, but not effective to detect objects small size- On the contrary, detectors with high frequency superior in finding small particles, however depth of range more limited.

Gold detectors generally use high frequency to target fine gold pellets, while coin detectors or treasure detectors exploit low frequency For the sake of reaching depth Bigger.

The type of detector MPS (Multi Period Sensing) Special because it is capable combining profit Two: In penetration At once. High sensitivity to the small object.

Besides, technology Multi-IQ emit multiple frequencies at once, offer optimal balance between depth and sensitivity, so very multipurpose for any kind of metal search.
