Does Anyone Here Swim With a Polar F4

I did do a search here and the questions are about whether or not the F4 can be used be for swimming (it can per website AND manual)

So my question is, does anyone here use it while they swim? Opinions?

I recently injured my knee and have had to go back to swimming for a while for my exercise, which is fine because I love swimming. I pretty much stopped when I got my Fitbit and focused on walking for my cardio. But now that I'm swimming I'd really would like to know what my true (or as accurate as possible) calorie burn is.
