This is a potential life saver! – Metal Detector Review

My wife, living in China, baked some traditional Chinese pastries for the Mid-Autumn holiday. As custom would have it, she placed a 5 Jiao coin in one of the nearly 100 she baked. This is supposedly lucky for the poor guy that bites into it. When I realized she planned to give these to her friends, I began to worry what would happen if a small child ate the one with the coin, which could easily choke someone. Other than cutting into every one, I was not sure how to find the "lucky" pastry! This app came to the rescue. I was able to find the pastry which contained the small, dime sized, coin in a matter of a couple of minutes. This app works very well. Much better than the other two I tried. Thank you for making this available for free!
