That is the coolest thing I've seen for a while. My only exposure to the Aqueon has so far been smudgy BW photos, only hinting at how the thing actually moves and works.

Thank you for the pictures and videos!

Also, 3 m/s for a monofin is not exactly "cruise speed". We're talking 50m sprint at the world record level, with gifted athletes who have trained for years and years for that single event.

2.5 m/s is already a pretty respectable monofin sprint and I doubt most freedivers will make even that (50m in 20 sec).

A reasonable "travel speed" for a monofin would be well under 2 m/s and for diving most go around 1 - 1.5 m/s.

Just to keep things in perspective...
