Inspiration Cave Dive

[DRE]

No scooter - just swimming. Let's assume an RMV of .4, which I would consider still somewhat on the high end for a diver who's comfortable in the water and who works out on a regular basis. With slightly overfilled AL80's you're looking at 55cf of gas going in on thirds, RMV of 0.4, average depth of 33ft gives you a little over 68 minutes to swim 3500ft - that's a very doable pace. The key is to work out (but most people would rather buy any piece of equipment instead of committing to running 5 miles twice a week) and streamline (the increase in effort with increased drag is just ridiculous - what the HC showed was definitely not a great example of streamlining).
