mweitz:
So,
How do folks feel about non GUE trained DIR divers? It looks like at least NAUI is getting on the bandwagon. Will the GUE Tech divers be able to do dives with the NAUI Tech divers? Will they want to? Do we think that as time goes on, the systems (from agency to agency) will slowly morph away from each other? It seems that at least one NAUI instructor has made modifications to some of the DIR systems.
Let's try to keep this a bit on topic and FLAME FREE.
If you post to this thread and have ANY affiliation with any training agency or instructors, please state it.
Thanks,
Mark

Required handouts(CD):
· Hogarth Grows Up; The evolution of DIR diving.
· The New Mysterious Malady; current thoughts on hyperoxic seizures
· The impacts of smoking on diving
· DIR details; the holistic system from mask to fins
· Understanding trim and buoyancy
· Cardiovascular conditioning and diving safety
· The oxygen window
· Patent Foramen Ovale; background and impact on divers
· The balanced rig
· The varying permeability model; a decompression razor
· Decompression experimentation
· The changing landscape of decompression
· WKPP assorted articles
Course Structure and Content:
Students will meet once weekly (Wednesdays usually) to discuss diving theory, logistics, dive planning or do training dives. Students will do presentations and quiz/exams to show mastery of diving theory. Open water dives will be planned after consultation with students with regard to scheduling and after adequate skill has been shown in confined water (pool) or similar environment. Dives will vary in complexity depending on environmental conditions and student progress. Diver training is designed to increase diver proficiency through proper buoyancy control, trim, propulsion and teamwork.
Prerequisites:
· Must be 18 years of age
· Complete student file including medical statement, release forms, and dive history
· Rescue diver qualification
· Minimum of 100 Open water dives with instructor discretion.
· Must be a Non smoker
· Must be able to swim at least 25 yards on breath hold and 300 yards free swim in 13 minutes.
· Prior to diving, the use of prescription drugs must be approved by physician and instructor.
· Student must log at least 30 minutes of exercise three times a week to be allowed to participate in any technical dive training or charters. This exercise program must be maintained for 2 weeks prior to any event to be qualified.
· Participate in at least 1 practice dive per month.
· Refrain from alcohol 2 days prior to an event.

Performance objectives:
Demonstrate proficiency in safe diving procedures, including pre-dive preparations, in-water activity and post dive assessment
Comfortably swim for at least 50 without a mask
Demonstrate the ability to deploy a lift bag
Efficiently and comfortably demonstrate how to donate gas to an out of gas diver in multiple gas sharing episodes
Be able to comfortably demonstrate at least one propulsion technique appropriate for environment
Demonstrate awareness of team member location and a concern for safety, responding quickly to visual cues and partner needs
Demonstrate reasonable proficiency with a single decompression bottle
Demonstrate a safe and responsible demeanor throughout all training
Passing all quizzes and exams
Required gear:
All students signed up for advanced nitrox and decompression procedures are responsible to supply the following;
Mask
Fins and booties
Wetsuit (7mm preferred with hood)
1 primary bottom timer/depth gauge
1 backup bottom timer/depth gauge
compass
wet notes/slate
surface marker with spool/reel
cutting device
back plate with harness
2 DIN first stages (configuration will be discussed in class) including one Submersible Pressure Gauge, one low pressure inflator hose, one 7 primary hose, and necklace backup.
1 DIN first stage for deco bottle
canister style primary light or similar.
backup light
Provided gear include:
double aluminum 80cu.ft cylinders with isolator manifold
Renting equipment is discouraged and will only be available after consultation with me.
Entry level trimix or advanced trimix are required to personally supply ALL above gear.
Cost for student:
Students are required to pay for the class at the first academic session. Boat charters and gas fills needs to be paid as appropriate. Books and certification cards are included in cost of class. Due to the nature of these classes and the significant costs accrued by the instructor and dive center no discounts will be given.
Class fees are as following;
advanced nitrox / decompression procedures $900
entry level trimix $1000
advanced trimix $1500
Academic Honesty:
Cheating will not be a problem in this class. All students will master all skills and theory by practical use.
Exams/quizzes:
There will be quizzes on each academic meeting to follow student progress. Each course will have a comprehensive final.
Grading:
All exams/quizzes must be mastered for passing.
