What Is the TDI Intro to Tech Instructor Course?

The TDI Intro to Tech Instructor Course trains qualified instructors to teach divers the foundational skills, equipment use, and planning habits needed for entry-level technical diving development.

This rating is not a decompression instructor rating on its own. The course focuses on teaching the foundations of technical diving in a no-decompression context, including technical equipment configuration, buoyancy, trim, propulsion, situational awareness, and advanced gas-planning concepts. TDI states that the course is strictly no-decompression, even when taught alongside Advanced Nitrox and Decompression Procedures material.

Best for: active dive professionals preparing to teach foundational technical diving skills.
Location: Playa del Carmen, Riviera Maya, Mexico.
Training focus: instructor-level teaching, control, evaluation, and risk-aware decision making.

This course is built for dive instructors with solid personal tech diving skills and who are ready to teach foundational technical diving.

Course: TDI Intro to Tech Instructor
Location: Playa del Carmen, Riviera Maya, Mexico
Level: Professional / instructor-level technical diving training
Training context: Technical diving foundations
Core focus: Equipment configuration, buoyancy, trim, propulsion, situational awareness, gas & dive planning, and student control
Best candidate: An active instructor who can explain the “why,” manage students in the water, and accept direct feedback.

During the course, the focus moves from personal performance to instructor control. You will be evaluated on how you brief, demonstrate, supervise, correct, and debrief foundational tech skills, maintaining the standard. This rating is a good next step for instructors preparing to develop students toward Advanced Nitrox, Decompression Procedures, cavern, cave, extended range, or trimix pathways.

What is the TDI Intro to Tech Instructor Course?

The TDI Intro to Tech Instructor Course trains qualified dive professionals to teach the first structured step into technical diving. The course focuses on teaching foundational tech skills, equipment configuration, buoyancy, trim, propulsion, situational awareness, gas planning, and student control.
This course is for active dive instructors who already have solid personal diving skills and want to begin teaching foundational technical diving concepts. It is best suited for instructors who value precision, conservative planning, clear demonstrations, and direct feedback.
No. The TDI Intro to Tech Instructor rating focuses on the foundations of no-decompression technical diving. It may include concepts connected to Advanced Nitrox and Decompression Procedures, but the Intro to Tech course itself stays within a no-decompression training context.
After successful completion, graduates may teach diving activities using technical equipment, provided the dives and environmental conditions are similar to those used during training. This rating is designed to introduce divers to technical foundations, not to teach beyond the limits of the certification.
Candidates must be certified as an SDI Open Water Scuba Diver Instructor or equivalent and as an Advanced Nitrox and Decompression Procedures diver or equivalent. Candidates who are already certified as TDI Advanced Nitrox and Decompression Procedures Instructors or equivalent also qualify.
The course includes four open-water dives with a minimum accumulated bottom time of 100 minutes. Training is structured around candidate readiness, group size, and instructor-trainer evaluation.
TDI requires a minimum of six classroom/briefing hours. Additional time may be used depending on the candidate’s preparation, teaching performance, and in-water control.
The maximum training depth for this course is 23 meters (75 feet). However, we might use shallower sites. The focus is not depth. The focus is control, teaching ability, awareness, planning, and safe execution.
You should be ready to demonstrate strong buoyancy, horizontal trim, no-silting propulsion, gas sharing, regulator drills, mask skills, SMB or lift bag deployment, team checks, gas analysis, gas matching, and pre-dive planning. The instructor-level expectation is that you can demonstrate these skills while also explaining, supervising, correcting, and debriefing.
You will be evaluated on your personal skills, teaching presentations, judgment, dive planning, student control, briefings, debriefings, and your ability to teach the TDI Intro to Tech course safely and clearly. Passing is based on meeting the standard, not simply attending the course.
You need equipment appropriate for the planned training dives and technical configuration. This may include a sufficient gas supply, an alternate air source, an SPG, a dive computer or depth/time device, a suitable BCD or wing, an SMB or lift bag with reel, exposure protection, wet notes or a slate, and nitrox-ready equipment when required. Confirm rental or equipment support with Divers UnderGround before booking.
Depending on your qualifications and training plan, this course may be taught alongside the TDI Nitrox Instructor Course. It may also be part of a broader professional development pathway toward Advanced Nitrox Instructor, Decompression Procedures Instructor, or other technical instructor ratings.
Playa del Carmen gives instructor candidates access to a serious technical diving environment in the Riviera Maya. At Divers UnderGround, the focus is mentorship, standards, and real teaching ability. You are not here to collect a rating. You are here to become a stronger, safer, more controlled technical diving instructor.
Send us your current instructor rating, technical diving certifications, recent dive experience, and professional goals. We will review your background and let you know whether this course is the right next step or whether additional preparation would be better first.
Contact Divers UnderGround with your certification history, recent dive experience, preferred training dates, and equipment configuration. We will confirm prerequisites, course availability, and the best path forward for your instructor training.
