I offer CCR training on the following types of rebreathers, the AP Classic Inspiration, AP vision, AP Evoulution and the Classic KISS and Sports KISS |
||||
Have you ever thought about diving in complete silence with no bubbles and extending your bottom time, getting closer to marine life for photographs. Then come and have a try dive on a Rebreather and experience the silence.

The major difference of the closed circuit system is that it maintains a constant P02 during the dive. This means that instead of planning a mix for a given depth, the rebreather constantly changes the mix to suit the depth you are at. This way the system is continually changing the 02 content to maximize 02 levels, and therefore minimize N2 levels. There is an increase of about 10% dive time over conventional OC or SCR Nitrox diving. Naturally the CCR is a more complicated piece of equipment and requires more involved training, but it isn't beyond the realms of most competent divers. If you hold an Advanced EANx certification and have good buoyancy and discipline, then CCR diving should not be too difficult. |

| AP Inspiration Closed Circuit Rebreather Training |  |
|||
The AP Valves Inspiration rebreather has revolutionized recreational and technical diving over the last 3 years. Quite simply this unit offers tremendous advantages for all theatres of diving. The system works on electronic controlled 02 injection which means that as 02 becomes metabolized by our bodies, the system automatically replaces the used 02 with fresh gas. Our metabolism does not change with depth, so the system is as gas efficient at 10m as it is at 100m ! The inboard 3 litre cylinder allows an average of 6 hours dive duration at any depth. As the majority of UK diving is below 20m, we feel that this system is ideal for SA diving as it maximizes the use of EANx to it's full potential. The other major difference of the closed circuit system is that it maintains a constant P02 during the dive. This means that instead of planning a mix for a given depth, the rebreather constantly changes the mix to suit the depth you are at. This way the system is continually changing the 02 content to maximize 02 levels, and therefore minimize N2 levels. There is an increase of about 10% dive time over conventional OC or SCR Nitrox diving. Naturally the CCR is a more complicated piece of equipment and requires more involved training, but it isn't beyond the realms of most competent divers. If you hold an Advanced EANx certification and have good buoyancy and discipline, then CCR diving should not be too difficult. The training lasts 5 days and cost $1100 plus boat fees. Please be aware that we need to complete at least 360 minutes of total in-water time, and when the training is done in the winter, this can mean long cold dives in fresh water ! |

Course prerequisites: Nitrox Diver (or equivalent at instructors discretion). A minimum of 50 Open Water dives. A good attitude accepting a "back to basics" approach. Course Structure: Day 1 - 8 hours of academic development - Reviewing the history of rebreather development and closed circuit rebreather use. A refresh on Nitrox diving physics including constant PPO2 theory and CNS% tracking. A history and in depth discussion of the Inspiration including electronics workshop. Day 2 - 4 hours of confined water training developing the survival skills needed to use the unit. Set point management, buoyancy control, semi closed rebreather mode, oxygen rebreather mode, bailout skills and mouthpiece management drills to mention a few ! Post dive maintenance and cleaning. Day 3 - Open water dives averaging around 60 minutes per dive practicing all of the skills learnt during the confined water training. These dives are done in around 6-10m of water. End of day post dive cleaning and maintenance. Day 4 - 2 Open water dives averaging around 60 minutes per dive practicing all of the skills learnt during the confined water training. Average dive depth on these dives will be 12 -20m. End of day post dive cleaning and maintenance. Day 5 - 2 Open water dives once again averaging around 60 minutes per dive practicing all of the skills you have been doing during the week. Average depth here will be 15-25m. Post dive cleaning and maintenance. Day 6 - The opportunity to do a deeper dive on the unit in the 20-30m range. End of dive trip cleaning and maintenance. Graduation !!! |

| KISS Rebreather |  |
|||
Rebreather technology is in a constant state of evolvement and with new and innovative products appearing constantly. The KISS (Keep It Simple Stupid!) Rebreather from Jetsam technologies is no exception. A mechanically driven constant PO2 Closed Circuit Rebreather, this unit is unique in its approach to Oxygen delivery. The KISS uses a static interstage pressure constant flow delivery system, similar to that utilised in Semi Closed Rebreathers to deliver a pre-set flow of oxygen into the loop keyed to the divers O2 metabolism rate. This flow rate roughly equates to the O2 being used by the divers body, any extra required is simply added by a press of the manual add button. Equipped with both an Automatic Diluent Addition Valve and OC/CC bailout mouthpiece the unit is easy to operate and a pleasure to dive. Simple to configure and adaptable to the divers changing needs the unit can be used as a simple Nitrox rebreather or with suitable training for advanced Tri-Mix diving. |
||||
The unit has no computers or alarms and relies on the diver to make there own decisions about the information being provided by the 3 simple redundant PO2 displays. |
||||
The unit is supplied in kit form for self assembly and requires the addition of a harness/back plate and suitable buoyancy bladder. The unit will take any BCD that would bolt to a standard twin set using 11" bolt centres. You will also need to provide suitable oxygen clean cylinders for the oxygen and diluent supplies. |
||||
Seaway Scuba are pleased to be able to provide a high quality KISS training course, this course covers all aspects of building and diving the unit using a normal O2 content diluent of air or helium mixes. We are also able to teach the experienced user advanced decompression diving techniques. |
