I'm currently very new to diving (5 dives solo so far), but I've done lots of studying on the topic of safe diving. It seems every video I watch/literature I read seems to beat the same things into my head over and over, mask clearing, understanding dive tables, boyles law, clearing 2nd stage, etc.
My question what is getting an OW cert going to do for me? I already own my own kit and get tanks filled so I don't really need to rent stuff. I just struggle to find the value of getting the cert when all the information is available online.
I picked up Deco for divers by mark powell and read it. I have a pretty good handle on the info and I have an Air integrated computer so the thought of going into deco doesn't scare me.
Open to all feedback please let me know.
