How they work.......

Post by Peter B »

As an electronic engineer I've always been pretty familiar with the various detector technologies and how they work, but I often found it difficult to explain to others when asked about it. Well quite by chance while looking for something else, I came across a web site which has excellent explanations of the three main detector technologies, VLF, PI and BFO, and some great little animations too. So if anyone's interested I recommend you have a look here and scroll through the pages
