Sounds crazy but this really works for me. I carry a small blanket with me and whenever I sense a shark is approaching I cover up my head so it doesn't see me. I have found that using a red hot nail to burn a hole in the middle of blanket lets the air underneath the blanket bubble out. It may take some searching to find a black blanket, but if you use a pink one you won't have to worry about anyone stealing it.
