GUEST COMMENT
We have just come back from Croatia where we did some diving. You must have spoiled us for we kept comparing the standards we met there with your well equipped centre and your always friendly, helpful and highly professional crew!

Rebreather Diving Overview

Rubicon Diving is a rebreather friendly Dive Centre and welcomes divers who wish to dive on their own rebreathers.  In addition, we can provide rebreather try dives, training from Level 2 (40 metres) to Level 5 Explorer (no depth limit) and instructor training on the following systems: AP Inspiration and Evolution, Megalodon and Copis, KISS, Liberty, SF2 and JJ-CCR.

How do Closed System Rebreathers work?

Closed circuit Rebreathers have revolutionised recreational and technical diving over the last few years offering tremendous advantages for all types of diving and Rubicon Diving offers training on a range of different Rebreathers. By moving from open circuit to closed circuit diving you can reduce the amount of gas you consume which is particularly important and more cost efficient as you dive deeper. Instead of breathing out metabolised gas into the water, closed circuit systems retain the spent air using a scrubber to remove Carbon Dioxide and an electronic or manually controlled oxygen injection system replaces the used 02 with fresh gas. Because our metabolism does not change with depth, closed circuit systems are as gas efficient at 10m as they are at 100m. The onboard 2 or 3 litre cylinders allow an average of 6 hours dive duration at any depth. As the majority of technical diving is below 30m, these systems are ideal for maximizing the full potential of EANX.

What Other Advantages do Rebreathers Offer?

The other major advantage of closed circuit systems is that they maintain a constant partial pressure of oxygen throughout a dive. This means that instead of planning an EAN 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 oxygen content to maximize 02 levels, and therefore minimize Nitrogen levels. By doing this closed circuit systems can increase your dive time over conventional open circuit or semi-closed rebreather Nitrox diving. By always ensuring that the gas mix you are breathing is ideal for the depth you are at, decompression times are much reduced. As closed circuit rebreathers are more complicated pieces of equipment than traditional open circuit systems they require more involved training. However, using these systems should not be beyond the realms of most competent divers and if you hold an Advanced EANX certification and have good buoyancy control and discipline, then CCR diving should not be too difficult.



The advantages offered by closed circuit Rebreathers are numerous and as many of our satisfied customers have found are well worth the investment in terms of time and money.
