Whites Electronics on March 15 2016 was issued patent number 9,285,496 B1 . This is special because it is a patent that covers the creation of a new Hybrid metal detector. It will combine VLF technology with Pulse induction. I`ve been detecting since 1979 and I finally feel like there is a new detector technology finally on the way. The last 30 years saw detectors frozen in the past. Looks like finally we have a real breakthrough.
