ADVANCED Wreck Diver

SO...... you have dived a few wrecks in your time, maybe entered and swam around a few times. But something has made you want to go further inside, venture round that corner, see what mysteries unfold!!!!  well now you can do just that - SAFELY

PURPOSE

The TDI Advanced wreck penetration course is designed to advance a divers skills to be able to plan and execute full penetrations into wrecks beyond the natural light zone. The program will also go into gear needs, advanced dive planning, gas management, team management, researching wrecks and mapping them. Depths shall not exceed the level in which the diver is trained and competent,

COURSE COSTINGS

$1200.00 for training, including cert fees and materials.

does not include boat costings diving the Waikato (budget for $120 for two dive days - will need 3 days diving)

Upon successful completion of this course, graduates may engage in wreck diving activities without direct supervision so long as:
1. The diving activities approximate those of training.
2. The areas of activities approximate those of training.
3. Environmental conditions approximate those of training.
 

Student – Instructor Ratio
Open Water (Ocean, lake, quarry, spring, river or estuary):
1. A maximum of four (4) students per Instructor. However, it is the instructor’s discretion to reduce this number as conditions dictate. (2;1 for wreck penetration)

  2. Demonstrate adequate pre-dive planning
    A. Limits based on personal and team gas consumption.
    B. Limits based on oxygen exposures at planned depths for actual mixes.
    C. Limits based on nitrogen absorption at planned depths for actual mixes.
  3.  Properly execute the planned dive within all pre-determined limits.
  4. Demonstrate the proper navigational techniques for the specific dive.
  5. Demonstrate out of air sharing with long hose through a restriction.
  6. Demonstrate the proper procedures for switching and isolating a malfunctioning regulator
  7. Demonstrate the proper techniques for locating a lost penetration line.
  8. Deployment of lift bag or up line for decompression.
  9. Silt-out procedures.
  10. Follow line with eyes closed.
  11. Follow line while sharing air.
  12. Follow line with eyes closed while air sharing.
     
  13. In order to complete this course, students must:
    1. Complete all field exercise and open water requirements safely and efficiently.
    2. Demonstrate mature, sound judgment concerning dive planning and execution
