Installation

Refer to our Installation Guide for step-by-step instructions on getting set up in less than 30 minutes!

Cord Length
The appropriate cord length for the ST3 Swim Tether is determined by various factors such as pool features and the swimmer's height and reach.

Considerations

  • Longer cord will be needed if install base is set further back than 1 ft
  • Is there a Baja shelf, a ledge or steps to avoid?
  • As a rule of thumb, cords will stretch 1/3 of its static length
  • While swimming, the ST3 will flex up to 39.5" from the centerline in its static position

Recommendations - every install situation is unique and may require some calculating. We've found that in most cases one of the following standard length cords will be ideal.

  • Standard - 4.5 ft cord for swim spas less than 10ft
  • Standard - 6 ft cord for most swim spas or pools less than 14ft
  • Standard - 8 ft cord for most pools
  • Custom - lengths are available up to 20ft

Comfort

For optimal comfort, place the belt on the front of your hip bones with roughly 2 inches of slack between the small of your back and the adjustable slider.

It Works great!!

It’s amazing and works great. I actually feel like I’m swimming through the water. But then when I look up, I’m still in the same place. I get a fantastic workout while enjoying every minute of it.

System Works Great!

This year we installed an 8' x 20' "container" pool - for those who don't know this is a SeaCan shipping container converted into a pool. Our pool has a max depth of 4' with a 10' length and a couple of shallower shelves at one end for the grandkids and sitting/lounging. We also have a 44" high railing that surrounds the container. I submitted a drawing of our setup to Swim Tether and Thomas was very helpful instructing where to mount our 6" x 6" post for the anchoring system. At his direction I installed the post 18" from the railing (at the edge of the pool) and at the height of the pool deck on our 4' deep section. The system works great and the pole while it does bend does not contact our railing which I wanted to avoid. We ordered the ST3 system as weren't sure which of the bungee lengths we would need. While the 4' cord works I found the 6' cord was perfect for front crawl, back crawl and back stroke. The 8' cord is too long for front crawl (I started contacting our shallower section) but does work for breast and back stroke. I was pleasantly surprised as to how quickly I adapted to the system and the strokes feel very natural. As you're not moving through the water there is more resistance as you swim however this is just a matter of scaling your workout accordingly. I'm really excited about this system as it will now allow us to get in meaningful swim workouts in our small pool. I'd highly recommend this system for anyone interested in swim fitness in a smaller pool!
