TDI / SDI Instructor courses

SDI OPEN WATER SCUBA DIVER INSTRUCTOR (OWSDI)

The SDI Open Water Scuba Diver Instructor (OWSDI) course is designed to teach current Divemasters or Assistant Instructors certified with a recognized dive training organization the knowledge to effectively function as an open water scuba diver instructor. This program is divided into two sections, an instructor development course (IDC) and an instructor evaluation course (IEC).

INTRO TO TECH INSTRUCTOR

The TDI Intro to Tech Instructor Course provides the training required to competently and safely introduce students to the world of technical diving. The objective of this course is to train instructors to familiarize students with technical equipment configurations, to enhance open water diving skills (such as buoyancy, trim, and situational awareness), and to introduce advanced gas planning techniques within a no-decompression context. Although taught in conjunction with material from the TDI Advanced Nitrox and Decompression Procedures courses, this course is strictly a no-decompression course; students are permitted to use enriched air nitrox mixes, provided the gas mix is within their current level of certification.

NITROX INSTRUCTOR

TDI Nitrox Instructor is an entry level course for instructors wishing to teach enriched air nitrox as a breathing gas. Little else has impacted recreational diving more than the introduction of nitrox, allowing more time underwater. During this course, instructors learn the benefits, hazards and proper procedures for teaching EAN 22 to EAN 40.

ADVANCED NITROX INSTRUCTOR

The TDI Advanced Nitrox Instructor Course qualifies Nitrox Instructors to teach the use of enriched air nitrox from EAN 21 through EAN 100 to a depth of 40 metres/130 feet during dives that do not require staged decompression. Often taught in conjunction with the TDI Decompression Procedures Instructor course, this can be considered the first step to beginning your technical diving teaching career.

DECOMPRESSION PROCEDURES INSTRUCTOR

The TDI Decompression Procedures Instructor Course prepares the Advanced Nitrox Instructor to teach the theory, methods and procedures of planned staged decompression diving. While this course is taught in conjunction with TDI Advanced Nitrox Instructor Course, it also can be paired with TDI Advanced Wreck Instructor as well as TDI

EXTENDED RANGE INSTRUCTOR

In the TDI Extended Range Instructor Course, the instructor candidate will receive training in the proper techniques, equipment requirements and hazards of extended range diving to depths of up to 55 metres/180 feet, while utilizing nitrox mixtures and oxygen for staged decompression.

TRIMIX INSTRUCTOR COURSE

While using helium-based breathing gases, the TDI Trimix Instructor Course delivers the training required to teach trimix diving that requires staged decompression. Utilizing gases containing no less than 18% oxygen, candidates will complete the four required dives up to 60 metres/200 feet.

ADVANCED TRIMIX INSTRUCTOR

Allowing dives to a maximum of 100 metres/330 feet and utilizing custom helium, nitrogen and oxygen mixes, the TDI Advanced Trimix Instructor Course is the crowning achievement for technical instructors. During the course, the instructor candidate studies a well-rounded curriculum and completes four training dives to demonstrate mastery of advanced trimix skills.

CAVERN INSTRUCTOR

As the first in a series of overhead courses, the TDI Cavern Diving Instructor Evaluation Course takes a serious look at the professionalism and skills of the candidates. Instructor candidates are evaluated for their level of knowledge and proficiency in presenting a TDI Cavern course as well as their proficiency in demonstrating land and water skills.While keeping a close eye on the overall attitude towards safety, the evaluator also considers the candidate’s ability to develop skilled, efficient and well educated divers that are aware of the environmental impact that divers may have in cavern systems.

INTRO TO CAVE INSTRUCTOR

Going beyond the light zone and building upon the values found in the TDI Cavern Instructor Evaluation, the TDI Introduction to Cave Diving Instructor Evaluation (commonly referred to as “Intro”), Intro Instructor candidates will have taught three cavern courses and assisted with at least one Intro to Cave course by this point. Having been recommended by a TDI Cave Instructor for this evaluation, the candidate will demonstrate the ability to educate overhead students in cave etiquette, communications and cave diving skills in an academic setting.Moving on, the candidate will demonstrate their proficiency in teaching in-water skills such as buoyancy control, S-drills, emergency procedures and lost diver drills to name a few.

FULL CAVE INSTRUCTOR

Far and above, the TDI Cave Diving Instructor rating is an outstanding accomplishment few can claim. Arriving at Cave Diving Instructor Evaluation, the candidate has conducted at least three Intro to Cave Diving courses as well as having assisted in at least one Cave Diver Course. Following the format as Cavern and Intro, the candidate, having been recommended a TDI Cave Instructor, will demonstrate many of the Intro skills as well as now adding academic subjects such as gas matching procedures for example. Additional in-water skills include air sharing through restrictions, lights out drills and traverses, gaps and circuits.

REBREATHER FULL CAVE INSTRUCTOR

Far and above, the TDI Rebreather Full Cave Diver Instructor rating is an outstanding accomplishment few can claim. Arriving at the Rebreather Cave Diver Instructor Evaluation, the candidate has assisted an instructor teach a minimum of two Rebreather Cavern courses, two Rebreather Introductory Cave Diver courses, and two Rebreather Full Cave Diver courses.

The candidate must provide their TDI Rebreather Cave Instructor Evaluator with a letter of recommendation from a Rebreather Full Cave Instructor they have assisted (this must be an instructor other than who is conducting the evaluation).

The evaluation will include a thorough examination of the candidate’s abilities to communicate and teach rebreather cave diving techniques, as well as evaluate the candidates own skills as a rebreather cave diver. The candidate will conduct a minimum of six dives with the evaluator: two dives at the cavern level, two dives at the introductory cave level, and two dives at the full cave level. The candidate will be required to perform all skills from the rebreather cave diving programs at a demonstration quality level.

CAVE DPV INSTRUCTOR

This course is designed to give the trained cave diving instructor the knowledge and basic fundamentals for the teaching of safely utilizing diver propulsion vehicle (DPV) in the underwater cave environment. Safe techniques, procedures and skill perfection associated with the use of DPV’s in cave diving is emphasized. Cave conservation considerations, such as low-impact application, are stressed.

STAGE CAVE INSTRUCTOR

The Stage Cave Diving instructor course is designed to give the trained cave diving instructor the increased knowledge and basic fundamentals for teaching  extended bottom times and increased penetration with the use of a stage cylinder. How to teach lengthened bottom times, accumulative decompression obligations and complex dive planning are covered in this course. Conveying safe techniques, procedures and skill perfection associated with stage cave diving is emphasized.

AIR DILUENT CLOSED CIRCUIT REBREATHER INSTRUCTOR
