Starting swimming, any advice?

[Nitefly]

I think I didn't mention it on here, but... after being an elite level 90 front crawl wizard, swimming 40 mins of front crawl four times a week in the fast lane...

... I ripped all my shoulder cartilage and needed surgery to repair it.

So yeah, mix up your strokes, folks!

heaart rate seems a bit useless
watch was slighly tighter on wrist and heart rate dropped 50%

yes - can't find any swim hrm comparisons between optical on a watch and a chest based strap, not even dc rainmaker , to show how far out the watches are.

I need to try an experiment alternating between the two, dont think you can simultaneously record two heart rate data streams.
