TDI Advanced Nitrox

Are you looking to expand your dive time? Maybe you’re a scientific diver or photographer looking to stay in the water a little longer?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. 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.

Who is this course 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
  • The certified diver who has interest in moving forward with technical diving education

Course prerequisites

(these requirements must be met prior to the start of the course)

  • Minimum age 18, 15 with parental consent
  • Minimum certification of TDI Nitrox Diver or equivalent
  • Proof of 25 logged open water dives

What You Will Learn?

Advanced Nitrox picks up where TDI 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

Skills:

  • 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

TDI Decompression Procedures Diver

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 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 is this course 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 prerequisites

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

What You Will 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
    • 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

Hollis Explorer2 Rebreather Course

A true recreational Rebreather

The unit is neither a fully closed circuit Rebreather nor a pure semi-closed system, but an intelligent hybrid that utilizes the best of both worlds. It's compact, lightweight and extremely easy to use.

The Explorer is unique in using a single gas; Nitrox, and is electronically controlled to achieve an optimal balance of PPO2 and dive time. Plug and Play absorbent cartridges, easy guided setup with go or no go, CO2 tracking, and 2 hour design duration make this a dream for any recreational diver.

The Explorer diver will benefit from breathing warm gas, have lots of bottom time, and since it does not produce any invasive bubbles, see more sea life than ever before.

We offer both small group pool demos and full certification courses on the Hollis Explorer 2 Rebreathers.

Step 1: Chose a Pool Demo or full Certification Class.

Step 2: Enroll yourself or recruit one or more dive buddies and select the option for 2+ students in the class.

Step 3: Email us <dive@wallins.com> some dates and times that will work best for you. We will contact you with a proposed class schedule based on your request.

KISS Closed Circuit Rebreather Course

Since the introduction of the first production model in 1999, KISS has earned a reputation as the most durable, reliable and easiest to maintain closed circuit rebreathers on the market. Due to its ability to be used in harsh, and extremely remote locations - which have included some of the deepest cave systems in the world - it has also obtained status as a true expedition-grade rebreather.

We offer both small group pool demos and full certification courses on KISS Rebreathers.

Step 1: Chose a Pool Demo or full Certification Class.

Step 2: Enroll yourself or recruit one or more dive buddies and select the option for 2+ students in the class.
