Potential Shark Repellant?

Hmmm... A Vancouver fisherman has invented a sound-producing device that mimics a pod of Orca Whales. He uses it to repel seals and prevent them from eating the salmon he catches. My first thought? I wonder if this new invention would work as a shark repellant??

Orcas are primarily bony-fish eaters, but have been known to prey on Great Whites and other top predators as well - see above. If this contraption would repel sharks, folks and sharks would be lot safer.

Need to look into this further...!
