This iPhone metal detector was developed by Adam Eisenman SM ’07. Not sure how well it would work at the beach for treasure hunters, but think how handy it could be at the airport. Find all that hidden change that will set off the detectors ahead of time. However you’d want to use it, it’s pretty cool. See it in action.
