ABSTRACT:
A swim training and buoyancy assist device for an anchoring device has a resilient element and a resilient tether. The anchoring device is located at a certain location beside a swimming pool. The resilient element has a proximal end and a distal end. The proximal end of the resilient element is connected to the anchoring device. The resilient tether has a proximal end and a distal end. The proximal end of the resilient tether is connected to the distal end of the resilient element. The distal end of the resilient tether is connected to a swimmer. When the swimmer is connected to the resilient element and the resilient tether, the swimmer can only move a short distance in a certain direction and is buoyed up at a certain depth in the water so that the swimmer, especially a beginner, can practice swimming in a small area without the fear of drowning.
