The Aqualung Calypso Regulator is the work horse of the Aqualung Regulator range - this reg will last forever and is very cheap to run - consider it a bit of a Hyundai. Built for easy diving - nothing too deep and not too strenous - which suits quite a lot of divers we know.
The Aqualung PRO LT BCD for someone that wants a BCD with no frills for lightweight travelling but that will still cover him when he is diving in the UK with his drysuit on.
