TDI Introduction to Tech Diver
Benefits or Features
Think you want to do Tech diving but not sure if it is for you? This course gives you a small introduction of what it takes to become a technical diver and what we do in the other courses.
Technical Description
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.
What will I be learning
Instructors may use any materials they feel help in the presentation of the required subject areas. The following topics must be covered during the course:
1. Physics
2. Physiology
3. Equipment Considerations
4. Dive Planning
5. Procedures
Before I start
1. Minimum age 18, 15 with parental consent
2. Minimum certification an SDI Open Water Scuba Diver or equivalent
3. Provide proof of 25 logged open water dives
What do I need
The following equipment is required for this course:
1. Primary cylinder(s) cylinder volume appropriate for diving conditions and diver gas consumption
2. Primary regulators
a. Primary and alternate second stage required on all primary cylinder(s)
b. Submersible pressure gauges are required on all primary cylinder(s)
3. Depth gauge and automatic bottom timer and/or dive computer
4. Buoyancy compensator device appropriate for equipment configuration
5. Ascent reel with lift bag/surface marker buoy
6. Exposure protection appropriate for local diving condition
7. Slates / wet-notes
What will I be doing
1. A minimum of 3 dives must be conducted; All dives must be conducted at depths within the diver’s current level of certification but no dives should exceed 23 metres / 75 feet
2. If the TDI Intro to Tech is taught in conjunction with Advanced Nitrox, only a total of 4 dives are required; more may be conducted at the discretion of the instructor
3. TDI allows instructors to structure courses according to the number of students participating and their skill level
