Passion Spas is the only Swim Spa manufacturer in the world to offer Current-Lift Technology,enabling the swimmer to remain prone on the water surface at any degree of current intensity.The Fitness Collection of Swim Spas is designed to provide an authentic swimming experience that adjusts to theintensity of your workout. Our innovative Current-Lift technology was developed by Passion Spas and automaticallyadjusts the water current to the intensity of your workout. As you decrease the force of the upper two swim jets, thelower swim jets automatically increase in intensity, creating more “lift,” providing more buoyancy as your swimmingspeed decreases. The faster you swim, the less lift is needed from the lower jets and the flow is directed to the upperjets for a stronger current. Swim Spas in the Fitness Collection also include Rowing Gear, Access Step and SynergyWater Maintenance System as standard features.
