The TDI Advanced Nitrox Course qualifies divers to use enriched air nitrox from 21% through to EANx 100% within your current certification level to a maximum depth of 40 metres/130 feet during dives that do not require staged decompression.
The Decompression Procedures course prepares you for planned staged decompression diving. With a maximum operating depth of 45m/150 feet, this course is your first step beyond the normal recreational diving limits. Your Instructor will provide you with valuable information and skills making you a safe and responsible decompression diver. You can choose either a single tank or twin tank option for this course.
During the Trimix Diver course your TDI Instructor will teach you how to plan and execute dives utilizing as little as 18 percent oxygen and diving to maximum depth of 60 m/200 feet with a blend of helium appropriate for the planned depth.
