Nope, no heart rate monitor, no stroke counter, no GPS, no power meter, none of that. Just swimming and a stop watch. So I guess we can all disregard this.
In all seriousness, thanks Tom; I’m thinking about getting the 2.
Get the 2. It is awesome! I think the 5 is too much. The 2 give just a little lift while allowing for full kicking and movement. We have been swimming in Lake Michigan the last few weeks. Water temps have ranged from 65-75. I was a little chilly on a couple days, but, usually the speedtube 2 was perfect. Keep “the boys” from climbing up into my chest cavity and the legs from cramping in cold water. Provided just enough lift to make a 3 mile swim (1 mile off shore) feel very comfortable while still making me work to develop my kick.
