I've never dived before, but believe that I will enjoy it, and now want to take classes. I've read a number of posts on this board, but I'm a little confused. Is there an advantage to taking OW and AOW at my LDS compared to taking those courses in, say, Roatan? Will I need to purchase my own equipment before a dive trip or can I rent equipment until I reach a level of proficiency that will allow me to make better choices? Basically, what's your advice for someone who has never breathed through a regulator, but wants to pursue diving as a hobby?
My general advice is this:
1st, become a good swimmer, in the pool, and then in your local area, in the local lakes, quarries, river, or whatever you have available locally. Always swim with a buddy.
2nd, become a good snorkeller. Learn to clear your snorkel and mask, to surface dive, and to swim underwater. Always snorkel with a buddy.
3rd, become a good freediver. Get to where a 15 ft or 20 ft freedive is easy and comfortable for you. Always freedive with a buddy.
Now, you will be totally ready for scuba. After those 3 sets of skills, scuba will simply be a matter of breathing under water, and very easy to learn. Go into scuba with a buddy, train together, and then dive together.
As to whether you should take your classes locally or at a warm water resort site, you would be a better, safer diver if you dived locally several times a year, locally, rather than just at a warm water destination once each year. That suggests that taking classes locally is superior to taking them away from home.
