I made a pledge to this. I think it looks pretty good, but I'm definitely a newbie when it comes to this. I like that it's small light and I can use my phone though. I just hope it works as advertised.

Looks like my link was removed. But, you can just google Air Metal Detector at kickstarter and see what it is. If the videos are real, then I have high hopes for it.
