TDI Open Circuit Courses
Intro to Tech
The TDI Intro to Tech Course is an introductory course that expands on recreational training by improving dive planning methods, in-water skills, and streamlining existing gear configurations in a controlled and fun learning environment.
Prerequisites:
- Minimum age 18, 15 with parental consent
- Minimum certification: SDI Open Water Scuba Diver or equivalent
- Proof of 25 logged open water dives
Advanced Nitrox
Are you looking to expand your dive time? Maybe you’re a scientific diver or photographer looking to stay in the water a little longer?The TDI Advanced Nitrox Course qualifies divers to use enriched air nitrox from EAN 21 through EAN 100 percent within your current certification level to a maximum depth of 40 metres/130 feet during dives that do not require staged decompression. Often taught in conjunction with the TDI Decompression Procedures course, this can be considered the foundation of your techn
ical diving career. TDI Advanced Nitrox is also a must for SCR or CCR divers.Prerequisites:
- Minimum age 18, 15 with parental consent
- Minimum certification of TDI Nitrox Diver or equivalent
- Proof of 25 logged open water dives
Decompression Procedures
Are you finding your no- decompression limits (NDLs) a limiting factor to dives? Do you have to ascend sooner than you would like? As sport divers, planned decompression is not something that we do or have been taught.The TDI Decompression Procedures Course prepares you for planned staged decompression diving. With a maximum operating depth of 45 metres/150 feet, this course is your first step beyond the normal sport diving limits. The TDI Decompression Procedures Course combined with the TDI Advanced Nitrox course form the foundation of all other technical courses. After these two courses and some additional experience, the stage has been set for you to move onto additional technical levels.
Prerequisites:
- Minimum age 18
- Minimum certification of SDI Advanced Adventure Diver, Advanced Diver, or equivalent
- Proof of 25 logged open water dives
Trimix
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.
Prerequisites:
- Minimum age 18
- Minimum certification of TDI Advanced Nitrox AND Decompression Procedures Diver, or equivalent
- Proof of 100 logged dives
Advanced Trimix
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 metres/330 feet utilizing hypoxic levels of oxygen (below 17 percent). This course is perhaps one of the most informative and challenging of all of the TDI open circuit courses. Upon completion, you will be among some of the most elite divers, capable of doing and seeing more while diving than any other divers out there.
Prerequisites:
- Minimum age 18
- Minimum certification of TDI Extended Range or Trimix Diver or equivalent
- Show proof of 100 logged dives, 25 must be deeper than 30metres/100feet
Nitrox Blender
Have you ever wondered how your nitrox cylinders are filled? Do you like the “behind the scenes” look at what makes a dive happen? Take the TDI Nitrox Gas Blender Course to find out how your cylinders get filled with nitrox! The TDI Nitrox Gas Blender Course will take you through the blending of nitrox in an easy-to-understand format.This course provides the training required to competently blend nitrox gas. The objective of this course is to train candidates in the proper techniques, equipment requirements and hazards involved in blending nitrox gases for recreational scuba diving activities.
Advanced Blender
Are you ready to progress on as a Gas Blender? The TDI Advanced Gas Blender Course picks up where you left off in the previous sequence in training, the TDI Nitrox Gas Blender course.After successful completion of the TDI Advanced Gas Blender course, you will be able to engage in the blending of oxygen and helium based gases. The objective of this course is to train candidates in the proper procedures needed for the preparation and blending of high quality nitrox and trimix gases for use in technical diving. The TDI Advanced Gas Blender course will take you through this process in an easy-to-understand format.
O2 Service tech
The TDI Oxygen (O2) Equipment Service Technician Course allows candidates the ability to engage in the preparation of scuba equipment for the use and exposure of oxygen and other mixed gasses used in technical diving. The objective of this course is to train candidates in the proper procedures required for oxygen equipment cleaning. This course may be combined with the Visual Inspection Procedures course at the discretion of the Instructor.
PADI Open Circuit Courses
Tec 40
The PADI Tec 40 course is where you transition from recreational scuba diving to technical diving. It’s a great place to start because it’s the first subdivision of the full PADI Tec Diver course and bridges the gap between no stop diving and full technical deep decompression diving. You gain experience and begin building the knowledge and skills you need to continue your tec diver training. You will qualify to make limited decompression dives to 40 metres/130 feet.
Tec 45
The PADI Tec 45 course is the second part of the full PADI Tec Deep Diver program. You’ll extend your depth limit to 45 metres/145 feet and learn to plan and execute repetitive decompression dives using a single stage/decompression cylinder. It puts you in a complete tec diving rig, which can be either backmount or sidemount. You’ll also make accelerated decompression dives using EANx or pure oxygen. This is a course where you’ll rise to the challenge and make the commitment to become a technical diver.
Tec 50
The third part of the full PADI Tec Deep Diver program is Tec 50. As a Tec 50 diver, you show that you’ve developed competency as a tec diver and have the skills to dive to a maximum of 50 metres/165 feet. You know how to make extended, accelerated decompression stops using up to two gases. It’s not easy to reach this level and earning your Tec 50 certification opens the door to deeper diving expeditions.
Tec Trimix 65
If you’re into technical diving then you know that to extend your depth range you need to use trimix – a blend of helium, oxygen and nitrogen. The Tec Trimix 65 course introduces you to using trimix down to a maximum depth of 65 metres/210 feet. There are advantages to using three gases, but you need to know how to do it right. Earning the Tec Trimix 65 certification makes deeper exploration a reality.
Tec Trimix
Ready for the outer edge of technical diving? The Tec Trimix Diver course takes experienced tec divers and turns them into extreme divers who go deeper and visit pristine sites where few others will ever go. During the course, you’ll make dives as deep as 90 metres/300 feet, but once you earn this tough certification, there are few limits. Your training teaches you to build experience gradually and you do it because you’ve made it this far and have more exploring to do.
Tec Sidemount
If you’ve looked into technical diving, you realize that tec divers always wear more than one tank. Sidemount is an increasingly popular way to configure multiple cylinders for technical diving. You can enter the world of tec diving with the Tec Sidemount Diver course and apply what you learn to other TecRec courses. This course may be integrated with the Tec 40, Tec 45 or Tec 50 courses.
Tec Gas Blender
The Tec Gas Blender course includes three practical application sessions, but no dives. During independent study and instructor-led review, you’ll learn:
- About the advantages and disadvantages of different blending methodologies.
- To blend enriched air and trimix blends to within one percent of the target mix.
- About the potential hazards related to handling oxygen, and how to manage those risks.
- To demonstrate the steps for oxygen cleaning equipment, along with the requirements for oxygen service.
