I read through the whole thread about bouyancy control and to be honest what struck me the most was the attitude of the author. What started out as a constructive thread with some good advice and some genuine concerns voiced as to the wisdom of rushing through courses turned into a slightly bad tempered affair and from what I could see most of this was due to the defensive nature of the postings made by the author. Confidence when diving is a great thing, as is the enthusiasm the author clearly has for the sport. There is a very fine line between confidence and cockiness however and to my eyes there seemed to be a slight cockiness about some of the postings which will immediately get the backs up of some of the more experienced divers. Perhaps rather than getting so defensive and simple, thank you for your concerns I have taken them on board would have sufficed.
I have only 60 odd dives and I have started my DM training. I was asked recently when I planned on finishing it and my response was somewhere along the lines of 'I have no idea' I have 101 things that I want to do first before I finish because I want to be as useful a DM as I can. I want to do a wreck/cave diving course and learn the basics of line laying, overhead environment diving etc. I want to do a Nitrox course and I want to understand and appreciate the advantages/disadvantages so that when a student asks me I can explain. I want to map more than one dive site and I don't want it to be the inland site that I do most of my training in and could map with my eyes closed. I want to do bad viz and no viz dives and learn how to deal with them I took a chamber ride recently, not because I had to but because I wanted to, to see what it was like and now I know and now I can tell students. I will finish my DM course but people who started with me will probably be long finished by that time, but I don't mind I'm in no hurry!
But that's just my opinion and everyone is free to agree, disagree, partially agree or tell me I'm rubbish.
