Most of this work can be done underwater more economically that in dry dock. Hydraulic tools and scrubbers will be used and demonstrated throughout this course. This course will teach the CDS divers and supervisors about the equipment and techniques used for boat hull cleaning and inspection techniques in the class room and in the open water.

CDS – 30 hours Underwater Exploration and Wreck Diving

The CDS course is devoted to the development underwater exploration and wreck diving techniques. Exploring a shipwreck will be a whole new experience for you when you are able to communicate while exploring. The procedures for penetration diving require a larger team with both underwater and topside tenders. Several unique aspects of wreck diving using surface supplied air diving equipment are covered. This course will teach the CDS divers and supervisors about the equipment and techniques used for underwater exploration and wreck diving techniques in the class room and in water.
