If you are fairly new to freediving like I am, and you want to really get something out of it, I can't recommend the Deeperblue.net SETT tank course enough.
I have just completed the course and it was one of the best things I have ever done and not just in a freediving sense. It is deffinately worth investing in if you are remotely serious about getting into freediving.
