Anti-Shark Gadget for Pussy SurfersS

This gizmo mounts on the tail of a surfboard, emitting low grade electrical signals that supposedly mess with a shark's muscles. Likely, it bothers the shark's sensory system, which detect changes in the water's electrical field as lifeforms slither through the water. (Maybe, to the shark, it feels like touching the ends of a dead 9v battery to your tongue.)

The device upsets the weight of a board a bit, so it takes a few runs to get used to. During that time, if you lose your balance, fall off, untether, and float into the mouth of a great white, you'll be pretty pissed you spent $700 on this fear-mongering piece of technology. Next week on Gizmodo: Portable lightning rod!
