TravisD:My brother just signed up for the "other" shop's 2+2 course. I'm really curious to hear what he thinks of it. He's already into it for about $700 in course+basics and hasn't even hit the pool yet.
I'm TravisD's brother and just completed my Open Water certification dives this weekend. I don't think there's anything inherently wrong with the two day course as long as you get a good instructor. I still have several things to work on, but I feel I'm safe and comfortable enough underwater to get experience without requiring a dedicated dive master or instructor just for myself.
Like a lot of people here have said, the value of the course definitely depends on the instructor (and the students). I had a great instructor and while I still have many things I can work on, I feel like I learned a great deal.
