I've just joined the 2n owners club after picking up a second hand unit a few days back - and whilst I'm still getting to grips with it - I live it...
As with all new owners though, I've spotted what may be an opportunity for some enhancements

1 - I couldn't find any way to display the battery in dive mode. Whilst I appreciate this is unlikely to a major issue, I find the being able to see the battery whilst diving with other DC's reassuring.
2 - It would be *really* helpful to be able to reorder the menu's to suit the user
3 - what happened to the tank icon? it used to be CF41 - why was this deprecated - I quite liked how that looked and whilst functionally it wont make a lot of difference, it looks cool, and lets face it, diving is all about looking fabulous
