Captain, I recently subscribed to this forum specifically to find non-preachy discussion relevant to solo diving. I'm doing solo training this weekend. Hopefully, a cert will result, but I'm looking forward to the training in any event. I've got a different mindset already just from reading the text, and am looking forward to learning more. How much I'll actually solo dive, I don't know; I just want the knowledge and the ability.
I think I see in some of this thread a split between establishment and anti-establishment types. Clearly, I'm an establishment type since I'm taking a course, but I realize others may see the establishment as perhaps too controlling and judgemental. Some seem to be taking exception to the right we all have to do whatever, including taking dumb risks if we want to, which has perhaps distracted from the real topic which I believe to be the safety of the OP. He certified four years ago, did nothing in the interim, then got in the water alone with an unjustified level of comfortable confidence. That isn't about solo diving in my mind, that's about somebody with limited knowledge and skill putting himself in an edgy situation, apparently without really knowing it.
I've participated in a number of really fun, enjoyable, challenging hobbies, all of which would be described by someone or another as dangerous. In every instance, the presence of a newbie doing clearly dangerous things, in apparent ignorance, has always resulted in the more knowledgable witnesses trying to help the newbie see the problem with what they're doing. Some people want to learn and appreciate it, while others figure they already know what they need to know and probably find the process intrusive.
I think the main point is that Fox is taking a needless amount of risk, with barely any experience, and the hope is that he'll re-evaluate his approach. I'm guessing he won't, given what he has written, but at least he's had the opportunity to hear the concerns, and personally, I think that's a good thing.
Fox, I hope you stay safe.
Captain, I hope you stay around because this doesn't seem to be a very busy forum, and it would be great if those with knowledge to share would stay.
