Hi, I`m Wreckreel. I`m an open water diver for 4 years now in New England. I`m kind of addicted to spearfishing and claming and for the past 2 years,I`ve been diving wrecks.(not many but some) I wanted to know, how does one become certified in regulator repair for this is another aspect of diving that I am interested in doing. Could you just pass this around and tell me what you think?
