Sorry.. When I meant 'it floats around'- i meant my hair was standing/floating vertically. My fiance (because she knows I wear a unit), said in good water visibility (6 - 10 metres, full sunlight) she noticed my real hear was floating a little differently to that of the unit. She said no one would ever notice as the goggle / mask strap was covering the line between unit and my natural hair and holding it all in place nicely.

Just to confirm, during the entire 13 dives I did (course, plus a few extras) the unit did not move at all (with a full cap adhesive the day before the 5 day course)

I'll make sure I am more clear

cheers
