Welcome to the board.
Why is it that you do not plan to dive an Rebreather in the near future ?
First, I feel that I still have a lot to learn and experience to gain on OC. Second, I already spent a lot of money on my gear recently (scooter, dry suit, etc). Third, for the dives I do at the moment, I don't need a Rebreather as a tool to achieve them.
When the time comes and I feel the limits are closing on me, I will consider to start training on a Rebreather. Maybe SCR, maybe CCR, I have not decided yet, I need to learn more about the various units and their potential problems. From what I have read so far, looks like the Megalodon is a top notch CCR.
Now, could somebody enlighten me here? When you dive a Rebreather, should one not plan for a worst case scenario where one has to bailout to OC at the end of the bottom time or at the furthest penetration point. Does that not involve that:
- in open water, you would have to carry just as much deco gas as you would on OC (and be sure that your diluent on OC gets you to the first switch point, or have to take an extra bailout bottom gas bottle).
- in an overhead (cave), you not only have to stage as much deco gas you would on OC, but you also have to stage bailout bottom gas to reach your first deco gas.
So at the end of the day, do you really need much less gas on a Rebreather?
