If you’re one of those people who loves ocean swimming, but hates the thought of all that leg-work to get anywhere, then you may be interested in a product which helps you scoot around quickly and easily with minimum effort. Kind of like a porpoise but without the cute noises.
These MSV Jet Boots provide super cool propeller thrust on both legs, using a Lithium Ion battery as the power source. The twin 6 inch diameter props give a top speed of 3.5 knots, and because the thrusters are attached to your legs it’s all hands free.
Judging by the marketing photos, you do appear to need some sort of menacing looking wet suit gear as part of the whole macho swim look, but if you’re prepared to overlook the lack of a pink version, this could be quite a fun tool. The somewhat bad news is the price at $31,500.
