How It Works

Three Steps to Endless Swimming

Simple setup. No plumber. No electrician. Just a fiberglass pole, a belt, and your pool.

Swim
Buckle the swim belt, push off, and swim in place. The pole flexes with your stroke for smooth, natural resistance.

Why Fiberglass

Engineered,
Not Improvised.

Cheap Amazon knockoffs use latex tubing that degrades in chlorine and snaps back unpredictably. Rope-based tethers jerk you at full extension. The Swim Tether is a purpose-built fiberglass system — the same material used in fishing rods, sailboat masts, and aerospace composites.

The pole flexes progressively with your stroke, and our Dynamic Stretch Cord is made from EPDM rubber — the same compound used in automotive weatherstripping and industrial seals. It delivers smooth, progressive resistance that increases gradually instead of hitting a wall. UV-stable, chlorine-proof, and built to last season after season.

One System. Three Levels of Flex.

Every Swim Tether uses the same base, belt, and cord. The difference is the pole — and the resistance it creates.

Swimming Pool Savior
I was about to get rid of my inground pool. It's too small for a 30-minute daily swim. An alternative would have been a FastLane system for about $17k — which would have rusted in 2 seasons. Swim Tether solved my issue. I swim and enjoy daily. One of the best investments ever made.

vs. $15k–$20k Jet Systems
It Swims Great!
If you have a pool that's not big enough to swim laps, you need one of these. A few hundred bucks vs a $15k–$20k add-on propulsion system is a no brainer. Way, way better than any of the tethers on Amazon. The quality is great.

Real Swim Stats
Better Than Expected
We built a small pool so we could heat it year-round. Swim Tether allows us to swim in place — easy to install, very easy to use. Even better, my Garmin tracks strokes, distance, strokes per minute — all the same stats I get swimming laps in a longer pool. Super impressed with the ST3.

Kids Train at Home
Great Option for Home Training
We bought this for our daughter who is a competitive swimmer. She was miserable once her swim club pool closed down. Our pool is a small, recreational pool, but with the tether she is training again as if she was back in a regulation pool.

Swim Spa, Year-Round
Several Times a Week
This is our second swim tether. We love it for our 8 x 14 swim spa. It is comfortable to use and long lasting. The first one lasted about a year and a half — outdoors year-round in Wisconsin with no protection. We use it several times a week.

Finally a Lap Pool
Best Invention Ever
I wish I had found this years ago. I can finally use my pool like a lap pool. You barely know it's there. I had barely used my pool before — it is just the beginning of May and I have already been in it more than the last several years combined.

Love My Swim Tether
I've been using my tether 1–2 days a week for a couple of years. I love being able to mix it in at home with lap swimming at the local pool. I also love the flexibility of mixing in a mask, snorkel, and fins for an awesome workout.

Arctic Spa Adapter
Pleased With the Fit
My wife and I are both using the Swim Tether and are very pleased with the base attachment that's specific to the Arctic Spa swim pool. Thanks also for a nicely attentive customer service representative.

Customer For Life
I have a 24-foot rectangular pool. My Swim Tether lets me wear fins and use a kickboard, so my workout is expanded. I've been using it since 2018; my belt finally wore out last summer and the company kindly sent a new one at a discount. Customer for life.
