COMBINED TDI COURSES
Do you want to complete dives to a maximum depth of 45m and accelerate your decompression? Learn how to maximise your bottom time and minimise the amount of time spent on decompression? If so, then combining Advanced Nitrox course with either the Decompression Procedures or the Helitrox Diver course is the perfect choice. This will give you the training and knowledge to plan and execute accelerated decompression dives and prepare you to move on to further courses such as the TDI Trimix Diver course.
What Will You Learn?
With theory covering aspects of decompression diving and utilising Nitrox mixes up to and including 100% Oxygen you will develop a strong base of knowledge, supplemented by excellent manuals and instructor led discussions. Theory sessions will take part around the dives, or can be completed at our classroom, giving you the most flexibility for your course.
In water skills using a twinset and single stage cylinder include START dive planning, safety drills, buoyancy and trim work, gas shutdown drills, stage handling and gas switches, amongst others.
You will complete a minimum of 6 dives over four days, with at least two dives deeper than 30m. Those divers taking the Helitrox course option will complete at least two dives using a Helitrox mix with up to 20% Helium. Upon successful completion of all in water skills and written exams you will have earned your new qualifications and you will receive two certification cards. These will allow you to purchase Nitrox and Oxygen fills and complete decompression dives based on your experience and gas limitations.
