-
Minimum age 18, 15 with parental consent
-
Minimum certification: SDI Open Water Scuba Diver or equivalent
-
Proof of 25 logged open water dives
What you can expect to learn:
-
In-depth dive planning, advanced buoyancy control, gas management, situational awareness, proper trim, gear configuration and selection
What’s in it for you:
-
Exposure to in-depth dive planning, introduction to more advanced technical diving and equipment
-
Opportunity to become a more proficient diver and expand on diver skills and knowledge
TDI Intro to Tech minimum requirements:
-
Execute proper gear selection and preparation as well as buddy gas matching
-
Mastery of S.T.A.R.T, trim, finning techniques, body positioning, and diver skills
-
Overall demonstration of mature, sound judgment concerning dive planning and execution
TDI Advanced Nitrox Diver
-
Usually done with Deco Procedures
Are you looking to expand your dive time? Maybe you’re a scientific diver or photographer looking to stay in the water a little longer?The TDI Advanced Nitrox Course qualifies divers to use enriched air nitrox from EAN 21 through EAN 100 percent within your current certification level to a maximum depth of 40 metres/130 feet during dives that do not require staged decompression. Often taught in conjunction with the TDI Decompression Procedures course, this can be considered the foundation of your technical diving career. TDI Advanced Nitrox is also a must for SCR or CCR divers.
Who this course is for:
-
The certified nitrox diver looking to expand their understanding of nitrox mixtures containing more than 40% oxygen
-
The certified nitrox diver looking to expand their in-water skills
-
The certified diver who has interest in moving forward with technical diving education
Course prerequisites
(these requirements must be met prior to the start of the course):
-
Minimum age 18, 15 with parental consent
-
Minimum certification of TDI Nitrox Diver or equivalent
-
Proof of 25 logged open water dives
What you can expect to learn:
Advanced Nitrox picks up where TDI Nitrox leaves off and offers a more in-depth look at diving with nitrox including:
-
Physics and physiology relating to diving with gas mixes containing more than 40% oxygen
-
Gas planning, dive tables, dive computers, oxygen limitations, nitrogen limitations
-
Equipment considerations, cylinder labeling, analyzing nitrox mixtures, gas blending procedures, and oxygen service ratings for using gases with more than 40% oxygen
Some of the skills you will complete in this course include:
-
Demonstrate buoyancy control; ability to hover at fixed position in water column without moving hands or feet
-
Show good awareness of buddy and other team members through communication, proximity, and team oriented dive practices
-
Demonstrate the ability to manage free flow from primary regulator in controlled fashion, shut down cycle, and switch to back up regulator
-
Conduct appropriate safety stop while maintaining neutral buoyancy
-
Demonstrate the ability to share air with buddy as both recipient and donor in a controlled manner while maintaining position in the water column
-
Demonstrate correct body position; appropriate trim, such as horizontal/streamlined when moving forward
-
Demonstrate proper stress analysis with self and dive buddy
What’s in it for you?
-
Ability to dive using EAN 21 through 100 percent oxygen provided:
-
The diving activities approximate those of training
-
The areas of activities approximate those of training
-
Environmental conditions approximate those of training
-
-
Ability to enroll in TDI Decompression Procedures, TDI Semi-closed Rebreather courses, TDI Closed Circuit rebreather courses
TDI Advanced Nitrox Diver minimum certification requirements:
-
Satisfactorily complete the TDI Advanced Nitrox course and written examination
-
Complete all open water requirements safely and efficiently
-
Demonstrate mature, sound judgment concerning dive planning and execution
TDI Decompression Procedures Diver
-
Usually done with Advanced Nitrox
Are you finding your no- decompression limits (NDLs) a limiting factor to dives? Do you have to ascend sooner than you would like? As sport divers, planned decompression is not something that we do or have been taught. The TDI Decompression Procedures Course prepares you for planned staged decompression diving. With a maximum operating depth of 45 metres/150 feet, this course is your first step beyond the normal sport diving limits. The TDI Decompression Procedures Course combined with the TDI Advanced Nitrox course form the foundation of all other technical courses. After these two courses and some additional experience, the stage has been set for you to move onto additional technical levels.

The certified Advanced Diver who has interest in moving forward with technical diving education
Course prerequisites:
-
Minimum age 18
-
Minimum certification of SDI Advanced Adventure Diver, Advanced Diver, or equivalent
