If you’re a surfer in, say, Australia, you may have considered investing in such sharky countermeasures as a Shark Shield or chain mail. Neither is perfect as the latter tends to make you sink, and the former apparently causes the occasional shark to eat it, as evidenced by a recent test in which a 10-foot great white took a bite out of a unit being tested.
The maker of the device promises that it does not, at least, attract sharks, but critics have suggested that the Shark Shield does no good and may in fact pose additional health risks due to its emissions. Maybe I’ll just stay on the beach.
