We built a relatively small pool so we could heat it all Winter and cool it all Summer. Swim tether allows us to swim in place in our pool. It was easy to install the anchor into the coping, and very easy to swim in place with a pool buoy, snorkel and goggles…just like I use in a lap pool. Even better, my Garmin does a very good job calculating strokes, distance, strokes/minute, etc…all the same stats I get when swimming laps in a longer pool. I am super impressed with the ST3.
