For those of us that were hoping that the Shark Shield would allow us to safely surf the sharkiest lineups in the world, there is a bit of disappointing news. Whilst being tested in South Africa, under the supervision of the Natal Sharks Board, a female great white ate a Shark Shield device that had been attached to a float. This has been the cause of speculation that the electrical fields designed to repel sharks might in fact attract them.
The manufacturer claims that the device does work but that due to the design it will only be effective while a surfer is stationary and waiting for a wave. If you are actually surfing, or paddling, you could be out of luck. At any rate, I cannot think of a more spectacular product testing failure than this one.
