THe issue that I'm having is that I live in a small town that's inland and the nearest instructor is in anther state. My brother has been certified for a few years now and so I would probably go with him.
Well, I have no idea of your brother's skills level, but here are my concerns:
{1} If your brother isn't very good, and you two practice together, you may get used to some bad habits; these habits will stay with you for a long time, and to overcome them you'll need a lot of effort.
{2} Since you mention that buoyancy is a problem for you, there is a significant risk of uncontrolled ascents; if, by mistake, you old your breath during the ascent... well, I don't even want to think about it.
The concern {1} is extremely likely to happen, and it will negatively affect your future diving.
The concern {2} is extremely
UNlikely, but if it happens it's going to be bad; Usually, I wouldn't mention this option, but your profile says that you have 0-24 dives and you said you are a new diver... this is why I am a bit worried.
Now, I can see two options:
option 1 - you really love diving and you are ready to commit a lot to this activity: in this case, take a weekend and go to the closest
good instructor; it's a holiday in the end, isn't it?
option 2 - you like diving, but not so much to commit a lot (at least, not yet
); in this case, don't waste your time in the swimming pool, just relax, plan a holiday in the beautiful Caribbean (or wherever you like), and take a course with a
good instructor about basic skills, while enjoying the colours of the tropical sea (or whatever you want to look at)
A
good instructor will help you avoid my previous concerns {1} and {2}.
Note:
good instructor = one that doesn't teach on the knees; some people will talk about this way of teaching as evil. I am not going to do it, because you will not die due to that... but you will have buoyancy issues and you will probably damage the environment. Therefore, it's better to avoid it! In my opinion, there are other requirements to qualify as a
good instructor, but that's another topic.
The two options that I proposed are a bit the black and the white; in reality, there is a bit of grey too (especially when adding some other considerations such as money), but it's up to you to decide the mix.
Whatever you end up doing, good luck and enjoy the depths!
