Project Description

TDI Extended Range Instructor

This course provides the training and experience required to be certified to competently teach air dives to 55 meters / 180 feet that require staged decompression, utilizing nitrox mixtures or oxygen (O2) during decompression.

The objective of this course is to train instructors in the proper techniques, equipment requirements, and hazards of deep air diving to a maximum of 55 meters / 180 feet and utilizing nitrox mixtures or oxygen for staged decompression.

The following skills must be completed by the instructor candidate. 

1. Properly analyze all gas mixtures to be used
2. Demonstrate adequate pre-dive planning limits based on:
a. Personal and team gas consumption
b. Oxygen exposures at planned depths for actual mixes
c. Nitrogen absorption at planned depth with actual mixes
3. Demonstrate the proper procedures for switching and isolating a malfunctioning regulator
4. Demonstrate the proper navigational techniques for the specific dive
5. On 1 dive, demonstrate an ascent with the ascent reel and bag or a Jersey up-line and perform staged decompression

  • Minimum age 21
  • Provide proof of 250 logged dives, 25 must be extended range dives
  • Certification as a TDI Extended Range Diver or equivalent
  • Certification as a TDI Advanced Nitrox and Staged Decompression Instructor or equivalent
  • Must have certified 10 students in advanced nitrox diver or decompression procedures diver, a minimum of 5 must be decompression procedures divers

The following materials are required TDI Standards and Procedures Manual, TDI Extended Range / Trimix Student Manual, TDI Extended Range / Trimix IG, TDI Extended Range / Trimix PowerPoint Presentation, Recommended text: Deep Diving: An Advanced Guide to Physiology, Procedures and Systems, Revised 2nd edition 1995 by Bret Gilliam with John Crea. 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.

Total number of dives you have done
Number of dives you have done on Nitrox
What technical certifications do you hold
Number of decompression dives you have done
How long you have been diving
Any significant gaps in your diving
What equipment you will need
