    If you’re going through all the trouble of having an electric field and a group of on-hand divers to scare away sharks, how is that much more of an accolade than swimming it with the cage?

    @luminum; the ‘shark cage’ creates a sort of a wake of negative pressure that assists the swimmer by reducing relative drag…a bit like the difference between running a marathon on a treadmill (keeping up with the belt) and on the streets (propelling yourself through space). either way, amazing effort.
