Thats a good ? Im not one of the "diving is sacred lets not listen to music" people but are you sure they don’t make any that go past 20 feet? sounds like its worthless for diving if thats the case. I was diving Weeki Wachee Spring last weekend for my open water cert and they were playing music in the water and it was incredibly clear. Would love to find an underwater MP3 that i could take to 100 ft + anyone know of any?
