TDI Advanced Nitrox Instructor
This is the instructor level certification course for instructors wishing to teach the use of EAN-21 through 100 percent oxygen (O2) for optimal mixes to a depth of 40 metres / 130 feet.
The object of this course is to train nitrox instructors to teach the benefits, hazards and proper procedures for EAN-21 through 100 percent oxygen (O2) for dives not requiring staged decompression.
a. Pressure review
b. Oxygen toxicity
i. Whole body
ii. Central nervous system (CNS)
c. Nitrogen narcosis
d. Nitrogen absorption and elimination
e. Carbon dioxide (CO2) toxicity
f. Carbon monoxide (CO) toxicity
3. Formula Work
a. Best mix computations
b. Maximum operating depth of a mixture computation
4. Equipment Requirements
a. Less than 40 percent
b. More than 40 percent
5. Dive Tables
a. Equivalent air depth (EAD) with any table
b. Computer generated tables (Pro-Planner, DPA, Dr. X, Abyss, etc)
6. Dive Computers
a. Mix adjustable
b. Oxygen (O2) integrated
7. Dive Planning
a. Operational Planning
i. Gas requirements
ii. Oxygen limitations
iii. Nitrogen limitations
b. Common mixing procedures (demonstrate one method) partial pressure mixing
c. Continuous blending
a. Enriched air nitrox (EAN) usage as deco gas i.e. 50/50 80/20 etc
b. Oxygen for decompression
The following skills must be completed by the instructor candidate.
1. Properly analyze gas mixtures
2. Demonstrate adequate pre-dive planning limits based on:
a. Personal gas consumption
b. Oxygen exposures at planned depth with actual mix
c. Nitrogen absorption at planned depth with actual mix
3. Properly execute the planned dive within all pre-determined limits
1. Minimum age 18
2. Minimum certification of TDI Advanced Nitrox diver or equivalent
3. Provide proof of 100 logged dives, 25 must be nitrox dives
4. Must have certified 10 students in entry-level nitrox
You will need a copy of TDI Advanced Nitrox Instructor Guide and TDI Standards and Procedures Manual. We will provide you with additional non course related reading when you book your courses via our online classroom.
The course cost is 31,000 PHP, this includes dives and tuition. We can arrange rental equipment, however we highly recommend you use your own if at all possible. Not included is the instructor materials, or professional fee with TDI. Please ask us if you need assistance with these.
We have a limited number of twin bed fan dormitory rooms for 2500 PHP per person, per week. These come with a kitchenette and bathroom, simple backpacker style.
If you prefer something else we work with a number of local resorts and hotels, or you might like to check services like, AirBNB we can help with local information if needed.
A typical hotel room starts from 1500 per night and up, the average would be around 2000 PHP. A typical self service monthly rental room or studio from 10,000 PHP and up, the average around 15000 PHP per month.
See here for more information on accommodation.
Contact the Course Director as early as possible, we can only accept a limited number of students on to each program, it is wise to book your preferred date in advance.
Please provide the following information when you book.
