What's the Best Pulse Induction Metal Detector?

2020-5-23  Most metal detectors operate by using Very Low Frequency technology. Basically, this means that these detectors have two coils – one to transmit electricity and the other to receive it as it bounces back from objects buried deep in the ground. Pulse induction (PI) metal detectors are less common, but they are quickly becoming more popular.

"Spirit PI" Wireless Metal Detector N.E.C.O

“Spirit PI” is a pulse inductions metal detector. This metal detector is based on an Arduino or ESP32 microcontroller and a smartphone.
