I had heard figures that suggested monofins might be faster. Then again, the 6 mph figure was established by a man in his early 50's, forty years ago. Wonder what an athlete might accomplish today? I threw the 6 mph figure in there as much for comparison to bi-fins as anything else. For normal free diving going particularly fast under your own power isn't that desirable a thing anyway.

Also, which is easier, running 6 mph or riding a bicycle that fast? It would be interesting to compare the relative energy expenditure of an Aqueon vs. a monofin. Could be similar or perhaps not given the moment arm and other aspects of the device. It is an old device that I thought deserved another look.

Has anyone on here spent sufficient time on both to be able to offer a comparison?
