Abstract: A swim tank slightly longer than a human and slightly wider than the maximum spread between fingertips is divided into upper and lower channels by polycarbonate or members extending across the width of the tank and having a rectangular outlet at the top front through which water is expelled. A vaned wheel at the rear is driven by an induction motor from a power source of controlled frequency.
