GPS Puzzle Box

Check out the GPS Puzzle Box that has its origins by being a wedding gift by Mikal Hart, where it will only open up in a specific location. The whole idea of this would be to travel to where the exact location is. Whenever you press the button on this, the LCD display on the lid will tell you just how far more you are from the target destination (in kilometers, of course). It won’t offer you any directions, so you will need to put your trigonometry knowledge to good use as you can only press the button 50 times.
