TDI Advanced Nitrox Decompression Procedures Course

TDI Advanced Nitrox Decompression Procedures Course

Join us for your TDI Advanced Nitrox Decompression Procedures Course and see how much more exciting it is when to be diving deeper, longer on bigger and better dive sites!

When it comces to technical diving, deep diving isn’t just setting a dive computer, seeing deco and calling yourself a tech diver, there is a lot that goes into becoming a technical diver, both mentally and physically.

Through our TDI Advanced Nitrox Decompression Procedures Course classroom and watermanship teachings, you’ll learn what technical diving is, advanced decompression theory, dive planning, gas management, decompression gas planning, as well as tracking both CNS and Pulmonary Oxygen toxicity.

You’ll learn how to follow a decompression schedule, handle emergencies, contingencies, plan for over staying your dive plan and ensuring you have enough gas to safely get yourself back up to the surface.

Decompression is a course requiring sound thinking and judgement. Decompression divers cannot simply ascend when they have a problem.  All issues must be solved underwater, especially with a decompression ceiling above you.

Students will complete a series of eLearning and classroom sessions, as well as local diving shore dives, dive charters followed by a completion of open waters and certification dives in 1000 Islands with us as part of our Rockin’ Rockport Trips.

Starts May 4/5 2024

Prerequisites:

Naui Intro to Tech
50 logged dives
Physically Fit
Must be able to swim 400 meters <10 mins.
Breath swim hold 50′

Availability:

This course is available privately for individuals or groups as well either locally or wherever you are located.

Your training will include a minimum of 7 dives (on air/nitrox not exceeding 130′) or 11 dives (with Helitrox not exceeding 170′) including planning and executing staged decompression dives conducted over a 4-7 day period.

Training Agency:

TDI

Additional Details:

Technical Decompression dives will be conducted on air/nitrox to a maximum depth of 40 meters/130 feet, or up to 150′ for those divers wishing to participate in the Helitrox Diver upgrade.

Divers can benefit from a clearer head, due to reduced narcosis and CO2 loading, maximizing gas elimination  gradients and hyperoxic decompression.

This course is your first step beyond the normal recreational sport diving limits.

This course introduces the prospective technical diver to many essential skills which will become instinct in a real technical diving environment. Some examples include: Emergency procedures and Failure drills, Gas Management, Bail out and Contingencies, Proper buoyancy and Fin Technique introduced during your Into to Tech Course, proper gas switches not exceeding MOD and more.

The Prospective Technical Diver must have the proper mind set and educational background and experience level to become a SAFE technical diver. Remembering that the technical diver cannot just simply surface in an emergency situation.

If you’re interested in this program a CD is available upon request with a wealth of information

Students will be expected to have maintained their skills at a level of at least NAUI Intro To Tech prior to the Start of this intensive training process or above.

Students will have to show up ready to dive properly and dive well or you will not pass this course.  All foundation skills must be completed with proper trim, buoyancy, time requirements and in the right gear configuration.

Cost:  1 Person $1500.  2 People $1200.  3-4 People $799+HST TDI Advanced Nitrox/Deco or $1 Person $1800, 2 people $1500, 3-4 people 1199+HST for TDI Advanced Nitrox/Decompression Procedures with NAUI Helitrox Diver (Hyperoxic Trimix >170′).  Course cost includes Certification Fee, Student Materials, online TDI eLearning code or NAUI Student Materials.

Accommodations, Park Entrance Fees, Gas Fills, Transportation and Dive Charter Fees are Extra.

What gear will you need?

You’ll need a Technical Diver setup with double tanks, decompression bottle (properly rigged with MOD).  Gear is to be Simple and Streamlined, complying with equipment configuration requirements.  A full gear list will be given to all candidates.

NAUI Trimix Course

NAUI Trimix Course

Our NAUI Trimix Course builds on the foundation skills and on the dive experiences of your previous technical courses, but with the addition of learning how to dive with more than one deco cylinder on dives requiring substantially more decompression time at deeper bottom depths.

Our course gradually steps you deeper and deeper as deco stops get deeper and longer and your dive sites get bigger and deeper.

You’ll learn how to manage Normoxic trimix mixes with a narcotic depth range of 100-130′ containing a bottom concentration of as low as 18% oxygen and as high as 23% oxygen through a series of training depths based on a maximum PO2 of 1.3-1.4ata for bottom mix and 1.6 for decompression mixes to a maximum training depth of 200′.

This course will be conducted locally and in Presque Isle, MI

Prerequisites:

Rescue Diver
NAUI Technical Decompression/TDI Advanced Nitrox/Decompression Procedures Diver or equivalent
100+ logged dives

Availability:

This course is available privately for individuals or groups available locally or wherever you are located.

Training Agency:

TDI

NAUI Technical

Additional Details:

Our NAUI Trimix Diver Course is for technical divers wishing to dive to a deeper depth taking advantage of the benefits of a true Trimix diluting the partial pressure of Nitrogen (reducing Narcosis) and in deeper diving dilluting the PPO2 to avoid CNS O2 Toxicity.

This course covers topics such as Helium, Oxygen, Nitrogen for breathing gasses. Argon, CO2, Carbon Monoxide, advanced physiology, physics and chemistry of diving (kinetic energy, specific heat capacity, tissue solubility and more), dive planning, table model comparisons, Isobaric Counterdiffusion and variations of trimixes are just a few of the many topics to be discussed. To enroll in either Trimix course, you must be certified as a diver with Advanced Nitrox, Decompression Techniques, Helitrox, Heliair.

The Trimix Diver Course consists of two levels. These courses will give you the skills and knowledge needed to minimize the risks of utilizing helium-based Trimix breathing gas mixes for dives to a maximum depth of 200′ (TDI) or 240′ (NAUI) requiring staged decompression and utilizing EANx mixtures and/or oxygen during decompression. This Team driven program offers some of the most challenging skills found in technical diving and test the diver more than any previous course to date in the students technical diving path. Upon Successful Completion of the course you will be able to plan and execute technical dives that require staged decompression and utilize helium-based trimix breathing gas mixtures and EANx and/or oxygen for staged decompression to depths within normoxic trimix ranges.

When the Diver gets to the Trimix level they are the most experienced technical divers. Extensive experience in double tanks is needed prior to enrolling in this course. We expect a minimum of 100 dives, 25 of which should have required mandatory decompression. Trimix Divers wishing to upgrade their skill sets, depth rating, knowledge and procedures will move into our Trimix Level II course.

Course does not cover cost of dive charters, gas fills, lodging or food.

Cost:  1 person $1500+HST.  2 $1200+HST.  3-4 $999+HST
