What Are the Differences between the PI Metal Detectors and Multi-frequency Metal Detectors?
As we all know, multi-frequency metal detectors and PI metal detectors are two main kinds of metal detectors. Many beginners may ask me that which one is bettter? My answer is neither is better, but they’re very different. Here are the differences between the two types of metal detectors.

Advantages for multi-frequency metal detectors:
1.Available for all types of hunting. Both on the land or beach.
2.Have discrimination functions, so that eliminate trash signals.

Advantages for PI metal detectors:
1.Good for gold nugget prospecting.
2.Great performance on beach searching or underwater detecting.
Both types of metal detectors own advantages. It is for the detectorist to decide which one is suitable for himself/herself.
