Hi Freedivers. Im new to freediving, having recently completed an Aventure Freediving 1 course, and able to get down to 10m so far. I plan to continue to do it recreationally and dont see myself going deeper than 20m. Im currently trying to choose fins... My requirements are that i would use them in the cold waters of Cape Town, but also the warm waters of Mediterranean... So maybe with a thin sock in Cape Town but definitely no sock in Mediterranean. I would also like to make sure its comfortable for surface swimming, and safe (not too fragile) for travelling with. I assume i need a soft to medium blade. I currently have my eyes on Mares razor, cressi gara 300 ld and leaderfins....any recommendations would be greatly appreciated.
