TDI Technical Courses

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 technical courses will prepare you for planned staged decompression diving.  Click the pictures below to find detailed information on these courses.
TDI Intro To Tech
The TDI Intro to Tech course is your first step into technical diving. This course is essential in teaching you how to dive technical gear configurations while maintaining proper trim and buoyancy.  In intro to tech, we will teach you how to set up technical gear, how to manage all the gear on your body, gas management, dive planning, and developing a technical diving mindset
TDI Nitrox Diver
 TDI Nitrox Diver Course is an entry level course for divers wishing to continue their diver education and utilize enriched air nitrox as a breathing gas to extend no decompression limits at depth. This course goes more in-depth than the SDI Computer Nitrox Diver deepening your understanding of nitrox. 
TDI Advanced Nitrox
 TDI Advanced Nitrox Course qualifies divers to use enriched air nitrox from EAN 21 through EAN 100 percent. Often taught in conjunction with the TDI Decompression Procedures course, this can be considered the foundation of your technical diving career. TDI Advanced Nitrox is also a must for SCR or CCR divers.
​
TDI Technical Sidemount Diver
Our TDI Sidemount Diver Specialty is a must for any diver wishing to use this increasingly popular equipment configuration.  It teaches students how to safely utilize side-mounted primary cylinders and how to manage side-mounted deco cylinders.
​
TDI Decompression Proceedures
The TDI Decompression Procedures Course prepares you for planned staged decompression diving. With a maximum operating depth of 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. ​
TDI Extended Range Diver
The TDI Extended Range course teaches you the proper techniques for utilizing compressed air as a breathing gas, and with a maximum depth of 180 feet, so you don’t have to miss those dives!The TDI Extended Range Diver Course provides the training and experience necessary including proper techniques, equipment requirements, and hazards of deep air diving
TDI Trimix Diver
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.
​
TDI 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 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.
TDI Cavern Diver
This course is designed to develop the minimum skills and knowledge for cavern and overhead environment diving within the limits of light penetration, and outline specific hazards associated with cave diving. The cavern diver course in not intended to provide instruction for cave diving environments. The objective of this course is to train divers in the proper planning, procedures, techniques and hazards of cavern diving.
TDI Intro To Cave Diver
This course is an introduction to the basic principles of cave diving utilizing a single primary guide line. Introductory cave diving is the second level in the development of proper techniques for cave diving, directly building upon the cavern diver course. The objective of this course is the perfection of skills taught in the cavern diving program, in addition to the adoption of additional techniques and procedures required for elementary cave dives.
TDI Full Cave Diver
This course is the third stage of overhead environment training in the series of TDI’s Full Cave Diver Development Program. Advanced cave dive planning, practical execution of different types of cave systems and scenarios divers encounter are presented. The objective of this course is to expand and critique previous skills accomplished in the TDI Cavern and Introductory Cave Diving programs. Emphasis is placed upon dive planning and skill perfection through actual cave penetration.
Hollis Prisim 2 Rebreather Course
The future of deep tec diving belongs to the CCR  and the Tec 40 CCR course is where it all starts. If you’re interested in technical diving and want to dive a rebreather, the Tec 40 CCR course is your entry into the tec diving realm. This first level of training introduces you to Type T CCRs, which can be electronic CCRs (eCCRs) and manual CCRs (mCCRs). During the course, you focus on developing the discipline it takes to be a technical diver while learning the details of proper setup, predive checks, dive planning, failure and problem management and teamwork for CCR diving.
