Hya All,
interesting idea this list
As Per mentioned I have done several dives bellow 70m on bifins the deepest being a 74m dive that took almost 2:50 and was very nice and clean (see profile)
I tried twice on competition to go for 71m on bifin but the first time at last years 3ple depth I stopped at 59,8 due to a failure to equalize and then at our summer games I got the tag but got a BO at the surface

.
Anyways - it was a lot of fun diving with bi-fins but following a comment from an unknown Austrian diver I spoke to in Dahab I have now switched to a mono (the guy show me after I had done my first PB past 70 walking out of the water with my fins under my arm - pointing at my fins and with a strange look on his face he said: "you went how deep with those things? ...you should try a mono")
So no more deep bi-fin diving for me...
Also to the list you can add Panos Lianos who has been to 66m in competition (Nice WC 05) - panos has done 71m in training and Giorgos Giorgas who also did 66m in competition with bi-fins.
Cheers
Stavros (Kastrinakis)
