The new swim joint by Swim Again is designed to give lower limb amputees the freedom of swimming without the hassle of specialized prosthetics. The joint can be released with a pull pin, allowing the user to walk to and from the water unassisted and eliminating the need for a separate water-sports device. The stainless steel model, which allows for salt water activity, weighs 1.39 lbs; the titanium model weighs less than a pound. The Swim Again joint should be a one-time purchase unless lost as the only part that will need to be replaced is the locking pin. One extra pin is included with every order.
