Technical Diving


Denver Divers offers two routes to arrive deeper and stay longer underwater - technical diving with mixed gases and rebreather diving. While a new open water student can be trained to be a recreational rebreather diver, we believe it belongs as a specialty course for open water divers who are comfortable diving on air and/or nitrox. The threshold issue is not what you breath - it is how comfortable you are in the water.

Our traditional tech diving program uses Technical Diving International (TDI) as our certification agency. For rebreather diving on the POSEIDON SE7EN, we use the SSI course materials.

INTRODUCTION TO TECHNICAL DIVING

The TDI Intro to Tech course is the perfect course for divers who have heard about technical diving and want to find out more about this exciting branch of advanced recreational diving. The course walks students through the special techniques, planning procedures and skills that set technical diving apart from traditional sport diving. It will show them how to improve their dive planning methods, in-water skills and streamline their existing gear configuration, in a non-threatening and fun learning environment.

The specific skills this course will highlight are:

  • Advanced Buoyancy Control
  • Gas Management
  • Situational Awareness
  • Trim
  • Gear Configuration and Selection

ADVANCED NITROX DIVER

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. Advanced Nitrox picks up where the entry-level Nitrox leaves off and offers a more in-depth look at diving with nitrox, including: Physics and physiology relating to diving with gas mixes containing more than 40% oxygen, gas planning, dive tables, dive computers, oxygen limitations, nitrogen limitations. Equipment considerations, cylinder labeling, analyzing nitrox mixtures, gas blending procedures, and oxygen service ratings for using gases with more than 40% oxygen.

Who this course is for:

  • The certified nitrox diver looking to expand their understanding of nitrox mixtures containing more than 40% oxygen
  • The certified nitrox diver looking to expand their in-water skills

Course Pre-requisites:

  • Minimum age 18 years old
  • Minimum certification of TDI Nitrox Diver or equivalent
  • Proof of 25 logged open water dives

Some of the skills you will complete in this course include:

  • Demonstrate buoyancy control; ability to hover at fixed position in water column without moving hands or feet
  • Show good awareness of buddy and other team members through communication, proximity, and team oriented dive practices
  • Demonstrate the ability to manage free flow from primary regulator in controlled fashion, shut down cycle, and switch to back up regulator
  • Conduct appropriate safety stop while maintaining neutral buoyancy
  • Demonstrate the ability to share air with buddy as both recipient and donor in a controlled manner while maintaining position in the water column
  • Demonstrate correct body position; appropriate trim, such as horizontal/streamlined when moving forward
  • Demonstrate proper stress analysis with self and dive buddy

DECOMPRESSION PROCEDURES DIVER

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.

Who this course is for:

  • The certified Advanced Diver looking to expand their knowledge of decompression theory and diving techniques
  • The certified Advanced Diver who is interested in extending their bottom time
  • The certified Advanced Diver who has interest in moving forward with technical diving education

Course Pre-requisites:

  • Minimum age 18 years old
  • Minimum certification of SDI Advanced Adventure Diver, Advanced Diver, or equivalent
  • Proof of 25 logged open water dives

What you can expect to learn:

  • Decompression dive planning, including:
    • Decompression gas choices
    • Tables vs. personal dive computers
    • Emergency and contingency planning (equipment failure, omitted decompression, etc.)
  • Decompression diving procedures, including:
    • Equipment selection
    • Pre-dive checks and drills
    • Stress analysis and mitigation
    • Following a decompression schedule
    • Gas switching
    • Team awareness and communication
    • SMB/lift bag deployment
    • Proper trim, buoyancy and finning techniques
    • Emergency procedures (equipment failures, catastrophic gas loss, omitted decompression, navigational errors, etc.)
    • Equipment considerations, cylinder labeling, analyzing nitrox mixtures, and gas blending procedures

The TDI Decompressions 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 into additional technical levels.
