BaduJet Swimstream BaduJet allows the pool user to swim, run or walk against a water current. The flow control knob regulates two powerful jets of water creating resistance for an enjoyable walk, jog or swim. It's virtually a treadmill in water with less pounding and harmful jarring caused by street excercise. Capable of creating a current in excess of 5000 GPM, the BaduJet's patented system can be installed in most pools, new or old, no matter what size or material. BaduJet also provides relaxation; the attachable hose produces a pulsating refreshing massage.
