What I’d be interested to know, that I’m having trouble finding, is the wingspan of the thing.]]>
The blade seems to be articulated…kind of airplane’s wing with the flaps moving. I wonder how much it weights. Looks quiet thick.]]>
I have discovered Bin fins in Antibes where finswimming french team is used to train.
I have been trainig with it in 2006 to prepare my -109m world record attempt and I did it.
I still use it in constant weight. it’s the most efficient fin when you are attracted by the surface (beginning of the descent) or when you need power to leave the bottom.
For dynamic apnea, it’s a good fin if you kick fast …
I’d say that on the way down I feel like wearing a 10 kg weight belt. ( I dive with no weights )
On the way up it is like being attached to an ascending ballon.
I know that Chen Bin has now different models. The one I am using is basically the same you can often see in constant weight competitions. The blade is very stiff and rather short.
When you order it black the footpockets and the wings are made out of a kind of tire rubber. I wouldn’t say that the fin has not a nice looking but it is definitly an absolute weapon in constant weight.
About the footpocket, I like it tight. My foot size is 44. Still, I ordered from Chen Bin a 47 and it fits perfectly.]]>
That thing looked really REALLY weird, kind of like a long sceleton or something. I think he said he’d seen it in Nice.]]>
When he took it out of his bag we all thought he was jocking.
Imagine two footpockets fixed on a 50 cm carbon axis. Then, going to the sides out of this axis, some fiber feathers with a pronounced “rocker”, all separated from each other by 5 cm gaps.
He said that after observing eagles flying over his farm in the french alps, he decided to realise that monofin. This guy is an aeronautcal engeneer.
We made a few dives with it between 50 and 60 m. It was hard to give an opinion…it was so different from all we had ever experienced before. It worked though.]]>
