TDI Intro to Tech

Price: $13000 MXN or $650 USD


The Intro to Tech Course is the start of your technical experience and expands knowledge on your recreational training. The TDI Intro to Tech course will improve your dive skills, dive planning, and equipment configurations.


The TDI Intro to Tech course introduces students to the world of technical diving.

This course is designed as an introductory course to the TDI Advanced Nitrox course and the TDI Decompression Procedures Course.

The objective of this course is to familiarize students with technical equipment configurations, to enhance open water diving skills (such as buoyancy, trim, and situational awareness), and to introduce students to advanced gas planning techniques within a no-decompression context. This course is strictly a no-decompression course; students are permitted to use enriched air nitrox (EAN) mixes, provided the gas mix is within their current level of certification. Intro to Tech may be combined with TDI Advanced Nitrox at the discretion of the instructor.

Required Skill Performance and Graduation Requirements

Students are required to successfully complete the following open water skills:

Land drills
1. Selection and preparation of equipment
2. Conduct team-oriented skills (buddy checks) for lift bag deployment
3. Gas matching among buddy teams
4. Demonstrate familiarity with basic hand signals
5. Demonstrate adequate pre-dive planning with limits based on the team
and personal gas consumption
Pre-dive drills
1. Use S.T.A.R.T. before every dive
2. Stress analysis and mitigation
*START is S-drill (OOA drill and Bubble Check), Team (buddy equipment
checks), Air (gas matching), Route (entry/exit and planned path
underwater), Tables (depth, duration, waypoints, and schedule).
In-water drills
1. Weight check
2. Demonstrate adequate buoyancy control (ability to hover at fixed
position in water column without moving hands or feet)
3. Demonstrate adequate trim (ability to maintain horizontal during the
descent, bottom, and ascent portion of the dive)
4. Demonstrate no-silting propulsion techniques: frog kick, modified frog
kick, modified flutter kick, backward kick
5. Demonstrate the ability to perform the following exercises while
maintaining trim and buoyancy in the water column:
a. Regulator exchange
b. Regulator recovery
c. Mask partial flood and clear with minimal air loss
d. Mask removal and clear with minimal air loss
6. Demonstrate the ability to perform a safety drill (S-drill) while
maintaining trim and buoyancy in the water column
