fails, and then there are epic fails. This case most definitely falls into the latter category, as Sea Change's shark-deterrent system (affectionately dubbed Shark Shield) was actually bit into by a great white when tested off the coast of South Africa. Reportedly, the device sends out electronic fields that are meant to deter sharks from coming near surfers, but according to the company's CEO, the botched trial was "due to a problem with the electrode's configuration." Furthermore, he noted that the thing is only "guaranteed to work when it's stationary, not when it's surfing in the wave or paddling." Needless to say, the effectiveness of these type devices have now been called into question, and regardless of whether this thing actually works as advertised, the lack of total protection -- you know, while actually surfing -- is enough to make us steer clear.
