Repellents come in different forms, from bracelets or anklets to surfboard wax. Some work by emitting electrical pulses underwater that aim to disrupt a shark's ability to home in on prey, while others give off a smell that sharks hopefully find unappetizing. But do shark repellents work? The most important thing to know about the deterrents is that they're not foolproof, shark behavior experts told CBS MoneyWatch.
