Carbon Fiber Twins (or, maximizing bailout gas efficiency)

(NB: experienced technical rebreather divers might find this post "boring" while beginning technical divers might find it interesting and provide you something possibly new to think about and non-divers will probably just frown and wonder what am I talking about). 🙂 I don't really know any technical divers who aren't also "gear hounds."

Since then, I've spent more time working on my photography skills (and equipment). I had watched a couple Wetpixel videos on photogrammetry recently and decided that, with Covid, I should learn more about it. I've [...]
