Yea I received a packet from Hall’s and my instructor went there it is rather expensive...From what I’ve read so far the best thing to do is to get your first 20 dives in and then do AOW, Then do another 40 dives which will be 60 and then you can go for dive master...then do another 40 dives to make 100 and then you can go for your Instructors....Thats alot of time...Ha.
