GUE DOUBLES PRIMER Double tanks: time, safety and redundancy

Don't hold yourself back

Have you ever wished you could stay down longer? Is gas consumption your limiting factor at 30m? Twin tanks (typically two 12L tanks connected together) are not just for technical divers, they are for anyone who wants to have plenty of gas for long shallow shore dives, feel safer when diving in the 18-30m range and/or want the redundancy for self-reliant dives. 

This 1-day, non-certification course teaches you the basic theory of twin tanks and the drills and skills you need to dive them safely and to their full potential. 

This is ideal for:
