Are you looking to expand your depth range? Do you want to reduce narcosis during deep dives? The TDI Trimix Diver course could be your next step!

As your motivation to explore progresses, you will find that you may want to go deeper to dive that wreck that is part of history or that cave system that you have read so much about. One of the major limiting factors of going deeper is narcosis; TDI’s Trimix Diver course shows how to minimize the effects of narcosis by adding helium to offset the nitrogen in your breathing gas. While taking the Trimix Diver course your TDI Instructor will teach you how to plan and execute dives utilizing as little as 18 percent oxygen and diving to maximum depth of 60 metres/200 feet with a blend of helium appropriate for the planned depth.

Who this course is for:

  • The certified Advanced Nitrox and Decompression Procedures diver looking to:
    • Extend their depth range
    • Reduce narcosis for all deep dives
    • Advance their technical diving education

Course prerequisites:

  • Minimum age 18
  • Minimum certification of TDI Advanced Nitrox AND Decompression Procedures Diver, or equivalent
  • Proof of 100 logged dives

What you can expect to learn:

  • Advanced decompression dive planning including:
    • Gas planning based on equivalent narcotic depths, nitrogen and helium absorption and elimination, CNS and OUT limits, Isobaric Counter diffusion, volume requirements, etc.
    • Decompression gas choices
    • Tables vs. personal dive computers
    • Emergency and contingency planning (equipment failure, omitted decompression, etc)
  • Decompression diving procedures
    • Equipment selection
    • Pre-dive checks and drills
    • Stress analysis and mitigation
    • Following a decompression schedule
    • Gas switching
    • Team awareness and communication
    • SMB/lift bag deployment
  • Proper trim, buoyancy and finning techniques
  • Management of multiple decompression/stage cylinders
  • Emergency procedures (equipment failures, catastrophic gas loss, omitted decompression, navigational errors, injured/unconscious diver, etc)
  • Equipment considerations, cylinder labeling, analyzing trimix nitrox and mixes, and gas blending procedures

What’s in it for you?

  • Ability to conduct technical diving activities using custom trimix mixtures without direct supervision provided:
    • The diving activities approximate those of training
    • The areas of activities approximate those of training
    • Environmental conditions approximate those of training
  • Ability to enroll in TDI Advanced Wreck and TDI Advanced Trimix courses

TDI Trimix Diver minimum certification requirements:

  • Satisfactorily complete the TDI Trimix Diver course written examination
  • Complete all open water requirements safely and efficiently
  • Demonstrate mature, sound judgment concerning dive planning and execution

The TDI Advanced Trimix Diver course is the top level of training for open circuit divers wishing to dive to depths as deep as 100 m / 330 feet utilizing hypoxic levels of oxygen (below 17 percent).  This course is perhaps one of the most informative and challenging and upon completion you are among some of the most elite divers. Your TDI Instructor will teach you:

  • Equipment management
  • Multiple stage cylinder labeling and placement
  • Complex decompression planning and contingency planning
  • Dive team awareness and communication
  • Gas monitoring and management
  • Use of travel gasses

The TDI Advanced Trimix manual is one of the most up to date manuals and includes all the latest of technology and practices being used.

Tek diving in Grenada. Living on the edge might be dangerous, but it’s got a great view! The Extended Range Course will take you well beyond recreational limits. After this course you’ll be properly trained and equipped to evaluate and plan dives where some of the less frequented wrecks and dive sites are. This course is exploring the limits to 55m for air as bottom gas.

One of the best examples for Extended Range diving in Grenada is the wreck of the Bianca C – the Titanic of the Caribbean. As the Bianca C starts at a depth of 34m and descends to 52m, recreational divers get to see only a small part of it for a very limited amount of time. As an Extended Range Diver you’ll be able to discover the entire wreck for a reasonable time – instead of having around 10 minutes at a maximum depth of 40m, just extend your depth and time to e.g. 50m for 25 minutes.

Tek Diving in Grenada. Welcome to one of the most unique experiences available to the recreational diver. The Decompression Procedures course is suitable for recreational divers to develop new skills and understanding as well as for technical divers who will participate in this course during a series of other courses. Actually ALL dives are decompression dives and this course is designed to help you understand the procedures and considerations of this type of diving.

The best option for you is to combine the Advanced Nitrox with the Decompression Procedures course, however. By taking these two courses together you will benefit of the high oxygen mixes for accelerated decompression at the end of actual decompression dives. (In combination with Advanced Nitrox – 4-5 days, 6 dives, with a maximum depth of 45 meters).

Tek Diving in Grenada. The Advanced Nitrox course picks up and continues with familiarizing you with the necessary information properly using all nitrogen-oxygen breathing mixtures as well as 100% oxygen.The standard nitrox course was designed to introduce alternative breathing mixtures without any special equipment considerations. Now, you will be using mixtures up to 100% pure oxygen, so cleaning and modification of certain equipment will be required. There are two direct applications of the Advanced Nitrox course. First, with hyperoxic mixes you may significantly increase bottom time at moderate diving depth. Second, you’ll get prepared to use decompression nitrox mixes. Included in the course will be an introduction to Gas Blending showing various techniques and actually seeing the system in operation at ScubaTech Dive Center. 4 dives to a max. depth of 40 meters, knowledge development.
