ST3 is the next generation of the Swim Tether Original ST001.

Introducing the ALL-NEW Swim Tether 3. Larger diameter poles and better fit and finish at the connection points make this the most robust tether system we've ever developed.

Quickly install and assemble to swim in most swim spas and swimming pools. A minimum of 14 feet of swim space is recommended. Using optimal lift and an elevated connection point allows the swimmer to be unencumbered by cords or restrictive ankle attachments.

Overall height 69-3/8"

Height installed in plate 66-3/4"

Features: Low impact, high resistance. Portable and packable. High quality construction. Comfortable and adjustable. Easy installation. Great for all ages and skills.

Recommendation on Cord Length: Various factors help determine the correct cord length. Pool features such as ledges and steps in addition to the swimmer's height/reach determine the swimming area. 

  • 4.5 ft cord for most swim spas
  • 6 ft cord for use in swim spas and pools in the 12-14ft range
  • 8 ft cord for pools greater than 14ft


This is not a lifesaving device. Do not leave children unattended while this device is in use.

Exactly what I was looking for.

Love, Love, LOVE IT!

My husband ordered this swim tether system for my birthday. Since our pool is small, two stokes, turn, two strokes, turn doesn’t cut it. I swam a mile yesterday with my tether. Awesome! Thanks so much!

Swim tether

Just bought the swim tether.I love it the belt sits around the hips & posterity has the elasticity band attached so great ergonomically.
Any stoke you can perform with good biomechanics.l ocean swim all year & now l can add this form of exercise to my own pool all year. No need for swim jets.
