Diving is so much fun! I kind of look at it like driving. You get good enough to pass your test, but you become a good driver through experience. Don’t stop trying to learn, even once you have your qualification. Watch what other divers, dive masters and instructors do, how they dive and try different things so you develop a diving style you’re comfortable with. Some general tips:
1. Dive with respect for the animals and the environment.
Don’t harass marine life, or treat coral like a stepping stone. Unless it’s a safety issue, you don’t want to be touching anything underwater.
2. Develop good buoyancy.
Buoyancy is how you control where you are in the water column. You can adjust this with weights and air in your BCD, but good divers can control their buoyancy with their breathing. This takes practice. You have to actively try to improve.
3. Learn your dive gear
Unfortunately we’re not marine animals anymore, and your dive gear is your life saver. Know what each of the equipment does for you. You are taught it in your courses but if you don’t dive regularly it’s easy to forget. Make sure your hoses are tucked in, so they don’t drag along the bottom causing damage to the substrate and your expensive gear!
That’s it for starters! Good luck, hope you enjoy it!
