The Tech 1 Plus Upgrade is designed to allow the Tech 1 certified diver to develop their technical diving skills and to progress towards more complex and advanced dives.  

The existing skills learned at Tech 1 will be expanded to include the use of a bottom stage to either allow more flexibility for multiple dives, or to allow longer bottom times. 

Students will be trained in safe gas planning and management strategies, failure management and resolution and contingency measures.
