The Pool Treadmill.

This portable swim current generator allows you to swim in your pool as if it were a full-sized lap pool, because its powerful 24-volt DC motor produces 80 ft. lbs. of thrust and a maximum speed of 6 M.P.H., up to 11 1/2-minute per mile pace, resulting in a wide, deep current without turbulence that allows you to enjoy extended swimming exercise for up to 30 minutes in an in-ground residential pool. It requires no special tools, plumbing, or electrical work for installation because it is self-contained; simply roll it to the edge of your pool using its built-in handle and lower the generator unit into the water. Two rechargeable 12-volt DC Series 27 marine batteries (not included) fully-recharge in four hours and are housed in a battery compartment that rests on your pool's deck, providing power for its patented propeller drive which generates the current. You can select your speed on the unit's dial for a light or vigorous workout. Plugs into AC for recharging. 25 1/2" L X 24" W X 18" H. (105 lbs.)
