Thank you for sharing this experience. FFM's have major safety downsides, especially with poor or no training. I am assuming you are one of the two divers in the video, please correct me if I'm wrong. I have a couple questions for my own education, I would appreciate your perspective if you don't mind.

What upsides do a FFM have for this sort of diving? I didn't hear the divers in the video speaking to each other, but maybe that's an artifact of the recording.

Was the buddy using a FFM as well, a standard OC reg/octo setup, or something else?

In the video, it looks like the diver had either a flood, or a failure to deliver gas (valve off, reg broken, something like that). What was the initial issue that the diver faced?

Once that issue occurred, the diver removed the FFM and performed a CESA ascent (the ascent was pretty fast, but you can see them continue to exhale as they go up). Was this the best solution to the problem?

Thanks again. Cheers.
 
The diver in the video is Sam Sam the Adventure Man, who used to work with Jared as part of Adventures With Purpose. In the comments on the video he said he had a mask flood due to an improperly seated reg, and had placed his octo in a position he was not used to. In addition, he believed his buddy was out of range to help and so when he couldn't find his octo, chose a CESA from 60 feet.

I expect that the advantage for them is in being able to narrate videos in real time while doing the dive.
 
No way that was 60 feet deep. Video looked fake to me, the video of the ascent was too smooth. Also he did not even try to find an octo as best I could tell.
 
I will gaurentee you that is 60 feet because I did my open water cert at that site and the base of the dome is 63 feet.
 
The diver filming should have offered his octo in this situation, but probably he had no training either!

So what was the ascent speed? Can you calculate it? Who filmed it?

The ascent speed at the end does not look very fast, which is when the speed might be highest in a panicked bail to the surface.
 
One of the things I always recommend when having tasks outside of normal diving, like catching crab, doing basic skills in shallow water with all the equipment used is a good idea.

A good reminder for me as I'll be on a rebreather and prepping wrecks for laser scanning next May.

EDIT: I think the split fins were a huge contributor though. :oops: :p :wink:
