ANyway can anyone tell me if i learn advance diving what will be covering? or things will be teaching or anything?
This is one place where SDI differentiates itself from PADI. PADI requires 5 additional dives to become an "advanced diver" Usually consisting of A deep dive to 100 feet so you can feel the effects of nitrogen narcosis if they appear, navigation, and then 3 other's of your choice. SDI requires Forty dives, along with completion of 3 specialty courses to receive "Advanced Certification" Will you be an advanced diver after completing either course? Probably not. I believe by the number of dives required in SDI you are likely to be more proficient. Becoming an advanced diver requires time in the water. A suggestion, when you are with advanced divers, model the way they dive. As far as education goes, the best course for your money is Rescue Diver from either agency, you will gain the confidence of taking care of your self, and being able to help a buddy in the event he or she should panic. Enjoy yourself, I've been actively diving the past 10 years.
