As a new diver myself I have learned one thing about divers in general. A diver will do anything for another fellow diver. We are one big family when we go diving. The most important thing I can say is if you are not sure about something then just ask. I do not know any divers that are not willing to help out a fellow diver. Lastly relax and enjoy the sites around you while in the water. This is a great sport to be involved in. Best of luck to you.
Sincerely
Bryan
