Description
TDI Advanced Mixed Gas CCR
The highest level of Closed Circuit Rebreather (CCR) training that TDI offers, the Advanced Mixed Gas Course will teach you how to use the full capabilities of a CCR. With a maximum depth of 100 metres/330 feet, this course opens up a whole new realm of diving including new wrecks, caves and walls to explore in depths you previously could not reach on a rebreather. This intensive course conducted over seven dives will focus on all the elements needed to plan and execute dives to these depths.
Who this course is for?
