What are PI (Pulse Induction) Detectors?
Pulse Induction (PI) detectors are an advanced type of detector used in metal detection technology. Unlike other metal detectors, PI detectors send short magnetic pulses and work by analyzing the effects of these pulses on the soil and metal. It is known for its advantages especially in highly mineralized grounds and deep searches.
Working Principle of PI Detectors
PI detectors send electromagnetic pulse signals through a single coil. These signals create an echo when they reach a metal object, and the device detects this echo and determines the location of the metal. Thanks to the technology it uses, it offers more stable results without being affected by soil structure or interferences due to minerals.
What are the advantages?
PI detectors offer an ideal option for both amateur and professional users with their many features:
- Depth Advantage: PI detectors can penetrate much deeper than other detector types.
- Adaptability to Mineral Grounds: Provides stable performance in highly mineralized grounds or on beaches.
- Sensitivity: It is good at detecting small gold nuggets as well as large objects.
In Which Areas Is It Used?
The most common areas of use of PI detectors are:
- Gold Prospecting: Ideal for detecting small pieces of gold known as nuggets.
- Coastal and Underwater Searches: Provides reliable results in mineralized grounds such as salt water and sand.
- Treasure and Ancient Relic Search: Preferred for finding large objects deep below.
Things to Consider
The discrimination ability (differentiation of metal types) of PI detectors is limited compared to other detectors. Therefore, if you are looking for sensitivity in distinguishing metal types, you may want to choose a different type of detector. However, if depth and performance in difficult grounds are your priorities, PI detectors are an excellent choice.
