Imersion Fins

I am posting this because I and some of my friends had enough with Imersion fins where it is getting cracked in a very short time the fins are the Black and Blue fins which are made for freediving... Please if anyone using those fins and having the same problem mention it here or i am not sure if they are only ones which are in UAE having this problem. The last incident was happend with my friend who used the Black type for 4 or 5 dives only before it crack... The blue fin had one crack incident but it can be normal because of use but the black fin will break in a very short time...

Hi guy and thnx for your feedback...

Actually i this is my feedback on the product which i had myself and two of my friends on their own fins. The technical reason why it was broken with me and not you i do not think that i can explain it but what i am sure about that it is Immersion fins two types (Black, and Blue) black was more easy to crack in short time. i Never had any info about the green one maybe because it is soft. I am not sure this material is not good for making stiffer fins... Also it never been used to push against the wall since the diver was spear fisher never trained in swimming pool... In the cases we had it is noticed that the white mark was formed first then break in short time (This is in the case of black Immersion) Never ment to say anything but just wanted to see if someone had the same case and maybe this will make immersion think about this design in future (Concerning the black one). Carbons are more nice but i have tried one from my instructor and was terrible because i am having worse fining technique LOL need to work on my fining first then get a carbon it is beautiful thing.
