For eight meters You can use about any fin, but I'd suggest getting one of the more popular freediving fins. You can find all available information with comparisons and opinions on here looking into the
equipment section.
Don't You have a buddy to go hunting with? Apart from making things a lot safer, it's usually also more fun.

- I think You might just find a bunch of people in Your area when You give a shout in the
spearo network here.
Have fun and safe diving!
