Tec 40 CCR Diver


The Tec 40 CCR course covers planing and making dives using air diluent and air or enriched air nitrox bailout gas on Type T closed circuit rebreathers to a maximum depth of 40 metres with a single decompression stop of no more than 10 minutes.

Tec 40 CCR Diver is the first level of training that addresses technical diving with Type T CCRs. This training is significantly more challenging than recreational rebreather diving because divers learn to be both a tec diver as well as learning to tec dive with a CCR.

The course includes four modules of knowledge development, five practical applications and 8 training dives. Theory is covering the tec diving phylosophy and approach, basic functions of CCRs, equipment selection and configuration, CCR setup, predive checks and CCR diving. During the practical applications, you'll cover CCR assembly, dissassembly, checks and planning. Confined and open water diving sessions should give you a minimum total bottom time of 500 minutes whereas the planned dive depth must be within the range specified for training each dive.
