The RAID Advanced 35 course is naturally the next step after your Open Water 20 course. It will help improve your in-water confidence as you learn about dive planning, underwater navigation, deep diving, buoyancy skills and finning techniques. The RAID Advanced 35 course is far superior to any other advanced training that you will receive on the market today. Beginning right from the start in your online theory, you will be introduced to and review gas planning formulas such as SAC (surface air consumption), EAD (equivalent air depth) and Dalton’s triangle in order to maximise your dive time, understand how to find the most ideal Nitrox mix for your planned dive and how to carry it all out safely – leaving nothing to chance! In your pool training session you will review and build on skills that you learned during your open water training as well as learn new, more advanced skills. RAID also offers a unique approach to perfecting finning techniques with a workshop teaching the flutter kick, modified flutter kick and frog kick. Your six open water dives will consist of buoyancy, navigation, rescue, two deeps to a maximum of 30 metres, and 35 metres and one elective!
