Just wanted to let peps know i got this thing called a key bouy at bass pro shops, its o one time use, cost 5 bucks but wanted to see how it worked, threw the keys in parents pool........keys sank then in boyt 20 seconds case broke apart and bout a foot long bright orange streemer belw up and my keys floated to the surface quick, the keys were even with the water, while the streamer was bout 8 inches out of the water. Really cool device and keys are easy to find, stayed floating for over 5 min till i grabbed em out, def worth 5 bucks, only thing is water activates it and once it deployes, you have to get another one.............
