CCR Diver (Hollis Prism 2 Tek)
The CCR Diver course is designed to certify students in the use of the Hollis Prism 2 closed circuit rebreather. Upon graduation students will be able to safely dive up to 140 fsw and conduct as much as 15 minutes of planned decompression.
Rebreathers truly are the future of diving and the Prism 2 is at the forefront of this evolution. By recirculating the divers expired breath the CCR is able to allow for exponentially greater bottom time due to gas consumption. Additionally, the electronically controlled unit can automatically, or manually, maintain a constant pO2 in which the rebreather keeps the air inside of the loop at the "best mix" nitrox for whatever depth you are at. This dramatically increases your no decompression limit as well as helps speed decompression.
Academic instruction consists of the mechanics of rebreathers, Prism 2 specific design and function, dive planning, emergency procedures and mixed dive team considerations. Confined water training will allow students to learn the intricacies of rebreather diving in a controlled setting while emphasizing emergency drills. Lastly, 6 open water dives will be conducted covering topics such as buoyancy control, descent and ascent, electronics manipulation, bailout procedures, hyperoxic/hypoxic drills, hypercapnia, flooded rig, SCR mode and much more
- TDI Advanced Nitrox/Decompression Procedures, IANTD Advanced EANx Diver or equivalent certification is required prior to starting the course. If requested these certification can be combined with the CCR Diver course.
- Minimum of 30 logged dives or sufficient experience to satisfy the instructor that the student has the ability and knowledge to continue into this level of training.
- To cross-over from a different CCR to the Prism 2 the diver must have 12 CCR dives on the different unit with one of those dives being within 45 days of the cross-over start date. Must obtain at least 200 minutes bottom time on the Prism 2 with at least 2 open water dives.
- Must be a minimum of 17 years of age with parent or guardian permission, or a minimum of 18 years of age without guardian approval.
