TECHNICAL DIVING DEFINITION :TECHNICAL DIVING DEFINITION What is “tech diving”?
TECHNICAL DIVING DEFINITION :TECHNICAL DIVING DEFINITION Enter a “ceiling” environment:
Wreck penetration
Cavern/Cave penetration
Decompression (“soft” overhead environment)
Use of gases other than air
Any time a regulator switch is required
Requires greater planning, more gear
WHY TECHNICAL DIVING? :WHY TECHNICAL DIVING? More possibilities
WHY TECHNICAL DIVING? :WHY TECHNICAL DIVING? The challenge
Physical
Psychological
Mental (intellectual)

No matter how much we prepare, there’s always the unexpected…We may end up in an odd place… :No matter how much we prepare, there’s always the unexpected…We may end up in an odd place…
HERE’S WHAT WE’LL COVER: :HERE’S WHAT WE’LL COVER: Training Considerations
Gear Considerations
Possible training progression
TRAINING CONSIDERATIONS :TRAINING CONSIDERATIONS Training today impacts what you can do tomorrow
General training vs. goal-driven training
Training & gear implications
Training agencies philosophies
Participation in trips, expeditions, exploration
Leadership possibilities
GEAR CONSIDERATIONS :GEAR CONSIDERATIONS What gear you currently own
What gear you will need to own
Specific gear, e.g. brands
Gear configurations
Flexibility?
Skills Transfer – gear mindset
WHICH TRAINING PROGRESSION? :WHICH TRAINING PROGRESSION? Gases?
Decompression?
Warm water?
Cold Water?
Overhead environment?
Rebreather?
MINDSET MOST IMPORTANT :MINDSET MOST IMPORTANT Your mind
= your most crucial gear
Your outlook
= where you’ll go & what you’ll do
How you’ll deal with setbacks & adversity

General vs. Goal-driven Training :General vs. Goal-driven Training Choice of training environment
Some overlap, e.g. wreck/cave
WHICH TRAINING PROGRESSION? :WHICH TRAINING PROGRESSION? Intro to Tech Diving
Basic Nitrox
Intermediate Tech Diving
Advanced Nitrox (>40%)
Decompression Procedures
Cavern Diving
Intro to Cave Diving/Full Cave?
Basic Trimix (200 feet)
Advanced Trimix (330 feet)
Wreck Penetration
A training recommendation: :A training recommendation: For all tech divers: at least Cavern and Introduction to Cave Diving Courses
Many benefits – many overlaps
Gear configuration
Buoyancy
Guidelines
Swimming techniques
A word about Full Cave training
Accident Analysis :Accident Analysis Basis for all tech training
Comes from cave diving
Slide 73:Unfortunately, we learn more from our own – and others’ -mistakes
Read
Discuss
Training Environments (cont) :Training Environments (cont) Warm Water vs. cold water
Less task loading in warm water
Definition of “Task Loading”
Warm water acquired skills must be transferred to cold water – practice!
Some adaptation required
Gear modification, e.g. line reels
Training & Gear Implications :Training & Gear Implications Agencies have different philosophies
Some specify exact gear
Some specify exact configuration
Manifolds vs. “independent” doubles
Where lights are worn
Choice of training agency & future implications for individual
Participation in Diving :Participation in Diving Training, experience, gear configuration
Mindset, adaptability
Many ways to accomplish goals
Example: Scapa Flow
Leadership Possibilities :Leadership Possibilities Variety of training
Different instructors have different strengths
Different experiences
Find your personal comfort level & philosophies
Slide 80:Gear Considerations
Your Gear Inventory :Your Gear Inventory Current
Immediate future
Requirements for training?
Long term needs
Can gear be “scaled up”?, e.g. computers
Specific Gear :Specific Gear Many brands
Compare
Speak to your instructor
Tied in with specific agency?
Gear Configurations :Gear Configurations Flexibility?
Example: lights
Travel bands
Allow different size tanks
Easy switching
Skills Transfer – Gear mindset :Skills Transfer – Gear mindset Need for new configurations
Creativity may be required
