Semiclosed Rebreather Training (Diver/Instructor)

PADI Semiclosed Rebreather Course (Dolphin / Ray / Atlantis I / Azimuth)

Imagine sliding through the water, accompanied not by the roar of bubbles, but by silence. Imagine getting close and personal with aquatic life – getting closer than ever before. When you dive with a semiclosed rebreather, you’re nearly bubble free – reducing the noise and disturbance that can scare away shy creatures.

Through either the Semiclosed Rebreather Draeger Dolphin/Atlantis Specialty course or the Semiclosed Rebreather Draeger Ray Specialty course you learn the special procedures for semiclosed rebreather diving. This includes special dive planning, organization, procedures and potential hazards, many of which differ significantly from conventional (open circuit) scuba.

• Must be a PADI Advanced Open Water Diver (or qualifying certification from another organization) or a PADI Open Water Diver (or qualifying certification from another organization) with proof of at least 10 logged dives beyond open water training dives, and be a PADI Enriched Air Diver (or qualifying certification from another organization)
• Number of Dives: Three
• Advantages and disadvantages

• Certification counts toward the PADI Master Scuba Diver rating.

TDI Semiclosed Rebreather Course (Dolphin / Ray / Atlantis I / Azimuth)

The TDI Semi-Closed Circuit Rebreather course is the ideal course for photographers, cold water divers or anybody wishing to enjoy a quieter dive and closer interaction with marine life. The course is unit specific covering the Dolphin, Ray, Submatix ST100 and the Azimuth. The SCR course topics and skills include

• System mechanics
• Nitrox review
• Gas physiology
• Bailout scenarios
• Pre and post dive system checks

The TDI Introduction to Semi-Closed Circuit Rebreathers manual takes you through a step by step process of the history and theory of SCR’s, how the units work, and provides setup and cleaning check lists. I will also show you how to use the Nitrox & Rebreather Equation software which helps calculate inspired gas and MOD.

Course Structure : DIVER - 3 days (academics + 1 CWD + 4 OWD)

The TDI Semi-Closed Rebreather Instructor Course, which includes the Drager Dolphin and Ray, Submatix ST100 and the Azimuth, trains instructor candidates to present the benefits, proper procedures, hazards and skills of SCR diving to students. Depending on the specific unit, up to six dives will be completed while accumulating up to 150 minutes of bottom time. Instructor candidates will demonstrate mastery of skills that include proper planning, pre-dive checks, bail-out procedures and PO2 monitoring to name a few.
