Home Made BFO metal detector


I read a couple of do it yourself metal detector write ups in the web as well as the one in the Comment/How page that looks exactly like the one on a page. So I decided to make my own too. However I made up most of it as I went around because the information on the web was incomplete or not very precise. So I decided to make one with exact measures and post it here so that everyone who wants to try it can be confident that they are making something that will work. Here's my first Comment/How-to so be nice :)
