@adobo thank you yes very interested, appreciate your time.
I want to touch a little bit on
@Fog King Reefer's remarks.
I fully appreciate that point of view. If you are an active diver long enough, it won't be long before you hear about a friend or acquaintance who lost their life while scuba diving. On the other hand, if you play golf long enough, you will also hear of a friend or acquaintance who lost their life playing golf. I know, it is absurd to relate scuba diving and golf. My point is that the very action of getting out of bed in the morning carries some level of risk. The more we understand what poses risks in each activity, the better we can prepare ourselves for safe and enjoyable outcomes.
I do agree that the ocean is powerful and can be unforgiving. My personal approach here though is not to necessarily to subject yourself to crashing waves and water being forced in every opening in your body and using that as a litmus test of whether I would be a good candidate for scuba diving. Instead, I took the approach of "stacking the deck" in my favor. Meaning, I took what I believe to be fantastic training. And I surrounded myself with likeminded, very competent divers. My approach was not the cheapest. And it wasn't the fastest. But I believe my approach (one that many others took long before me and many others followed after me) has consistently produced competent divers - leading to some divers progressing far enough to do some of the most challenging dives in the world.
Additionally, when it comes to diving, I have very narrow parameters for the kind of conditions (and dive buddies) I am willing to dive in. In the beginning, when I was just learning, the parameters were very very narrow. As I became more competent and more experienced, the parameters expanded but still remained in place. As an example, I don't do beach dives if I can't easily and reliable enter and exit. I poll other divers to see what conditions are like before I get in the water - here in California, it is not unusual to get into the water and find a ton of surge. In those cases, the dives might not even be worth it.
I don't believe you need to be a super human to dive proficiently and safely. You just need to identify the conditions by which you will be comfortable to go diving. In the beginning, that might be clear days in shallow water (20ft). Later on, your experience and skill might let you be comfortable diving in conditions that would scare the poop out of diving instructors.
I guess that is a long way of saying that if the 3-5 day course is not doing it for you. Don't rush it. If there is room in the budget, consider taking a more comprehensive certification class.
Side note: When I got certified, I got buddied up with some random guy from the class. Even as a newb, I could tell that something was missing from my class. Anyway, as we progressed, I asked my buddy if he was considering getting more comprehensive training. He said no, that was a waste of money. Shortly thereafter, I saw him buy a $1k dive computer from the shop. He spent $250 on training and $1k on a computer. My advice to you, be willing to spend on training. Scuba, just like any other activity, is so much more fun when you are skilled at it.
I know I am wandering here but I have one final thought on "surrounding myself with competent divers". What I mean by competent divers aren't loudmouth, know it alls. And certainly not ones who espouse solo diving for new divers. Or divers who try to solve skill deficiencies with gear. I am talking about people who are thoughtful and seem like they are thinking several steps ahead. The divers you dive are just as crucial, if not more so, than the equipment you dive with. Your dive buddy will help you see trouble before it happens. And help you address issues that you cannot address yourself. They will help you balance out tasks so you do not get overwhelmed. And if fit hits the shan, your dive buddy is another resource to get you home safe.
Ok, to summarize:
1. Take your time, it is not a race. Anytime you feel things might get away from you, thumb it. Whether it is training or on a dive.
2. The quality of training you take is just as important, if not more important than your gear. Good training will help you identify what a good starting point is for the parameters for which you would be comfortable to go diving.
3. The quality of your dive buddy is just as important, if not more important than your gear. Choose them like getting home safe and sound depends on it.
