Short video on my recent dive to the RBJ at 270 Feet in Pompano Florida. Sorry, it's a little shakey.

Way Cool!! Thanks for posting!! Question,,,,, if you should happen to have a major failure on your CCR at that depth what is the scenario to get to the surface safely? Keep in mind that I don't have a clue about them!!

The simple answer is to switch to your OC bailout tanks and ascend.

Cool dive and video. That one shark really took an interest in your friend. HaHa. On a side note, and I am not knocking rebreathers but in reallity you really sometimes don't really carrie enough bailout gas to get you out of a serious deco schedule that a rebreather can get you into to...right? So it is a team assisted return to the surface? Charles and I have talked to great lengths about it. Would anyone care to post the deco stops pertaining to this dive. Still, really enjoyed watching the video and I don't dive a rebreather yet but do embrace them.

From that depth what are your deco obligations when on CCR?

Pretty good visibility and light at 270 fsw.
The youtube page says that this video was filmed with a go pro Hero 3+ black in the Hero housing.
According to the Go Pro web page, the Hero housing is rated to 40 mts (130 fsw). Too risky to go so far beyond rated limits.

Be careful with your goPro!

So no body wants to answer the question?

I can not speak for the guys doing this dive or the OP, just myself and my buddies. We do carry enough bailout and very very very seldom rely upon team bailout.

The deco and bailout gas needed for this dive is very dependent upon both how deep we venture and our bottom times. If we are lazy and do not want to carry 3 tanks then we will limit our bottom time to allow for less bailout, but if we want to deal with the 40 of O2 also we will stay a bit longer.

If I figure a max depth of 250' and a bottom time of 27 minutes, I will end up with about 100 minutes of deco and will need 80cf of 18/45, 80cf of 50%, and 40cf of O2. My total runtime will be almost identical whether I am on CCR or bailed out to CC.

I might be a little off on the exact numbers since I am doing this off the top of my head. This is one of our typical dives that we just use the same plan for each time.
