Took this to Belize and decided to set it in the back of our kayak instead of around my neck. Well, kayak flips, phone goes in the water. My only mistake was thinking it floated. Sank right to the bottom. After 45 min of snorkeling in about 8 ft of water we found it and thank goodness it was airtight and never let any water in!! Note to yourself: wear it around your neck or attached to something always!
