The original and best!
These fins have been the standard for many divers for over 20 years
A very powerful fin, that does require a bit of getting used to if you are new to diving or have previously used a less powerful fin
My personal choice when I know that the dive might require the ability to move against the tide
Fitted with the popular Mares Bungee strap, more comfortable and longer-lasting than the spring type – in my experience
