Last week our pals at Gizmodo stumbled on an Instructables project for hacking a metal detector with a hydrocarbon sensor. The goal: use it to find oil you can extract and sell for $$$ OR locate underground toxins, so you can try to sue whoever put them there (win win, if you ask me).
Have you an opinion, used or been to this object or place? Tell us what you like don't like about it, or post any specs/info about it:
