This SSI specialty will allow an OWD or Advanced OWD to explore the 40-meter zone with a guide.
You will benefit from SSI’s theoretical instruction and safely discover the specific characteristics of the area and its requirements: the altered perception of this new environment, the imperatives of stabilization, and you will learn to communicate at depth for dives within the safety curve.
This specialty is a requirement on your path to becoming an SSI Divemaster.
