Technical Wreck Diver

Purpose

This Program is designed to train divers in extended wreck penetration diving and the technical utilization of EANx for wreck exploration and the use of EANx and oxygen for decompression.

Prerequisites

  1. Must be qualified as an IANTD Deep Diver or equivalent. For Technical Wreck Diver Program, must also be qualified as an IANTD EANx Diver.
  2. Must provide proof of a minimum of 70 logged dives, or a minimum of 40 logged dives with qualification as IANTD Wreck or Cavern Diver. If dives in the course below 130 fsw (39msw) are planned the diver must have 100 logged dives.
  3. Must be a minimum of 18 years of age.

Texts

  1. IANTD Wreck Diver Student Manual & Workbook, or equivalent text(s) approved in writing by the Board of Directors (written approval will be issued by IAND, Inc./IANTD World Headquarters).Additionally, if Technical Wreck Diver Program is taken concurrently:
  2. IANTD Technical Student Workbook.
  3. IANTD Technical Diving Encyclopedi

Program Content

  1. This course may be taught in conjunction with a Normoxic Trimix or Trimix Diver course.
  2. This Program must include a minimum of 150 minutes of bottom time completed within at least 6 wreck penetration dives. At the Instructor’s discretion, dives may be credited as specified in the Standards. With maximum crediting of dives from other Technical Diver Programs (Cave, Technical Diver and Trimix) or experience, a minimum additional 100 minutes of bottom time must be completed on wreck dives.
  3. To complete the course within the minimum specified dives students must have an average of 8 points (out of 10) on he watermanship evaluations. With 2 or more additional dives the student may graduate from the course with an overall average score of 6 points.
  4. Land Drills: 
    • Basic use of safety lines and reels will be performed on land.
    • Simulation of wire entanglement will be practiced.
    • Equipment Requirements
  5. All students must be taught the concept of gas matching.
  6.  All bottom mix tanks must be equipped with dual-outlet manifold valves. Independent cylinders may not be used. If a rebreather is used, it must be equipped with adequate bailout.
  7. A stage decompression cylinder containing oxygen or an EAN mixture with at least 50% oxygen, and appropriately labeled.
  8. Two Primary regulators must provide ample gas flow. One second-stage hose must be at least 5 feet (1.5 meters) in length; longer hoses are recommended.
  9. A primary BCD is required and a backup BCD is recommended. Back flotation is recommended. If a dry suit is used, it may serve as the backup BCD.
  10. Submersible dive tables as a backup to a dive computer or for control of the dive at the Instructor’s discretion. If computers are used, it is recommended that two computers be used on planned decompression dives.
  11. Two reels: one for penetration and one for decompression / lift bag deployment.
  12. A lift bag of at least 50-lb (22.5-kg) lift capacity for a decompression marker.
  13. Two lights: one primary light (minimum 20 watts) and one backup safety light.
  14. Compass.
  15. Bolt snap hooks are recommended for all equipment attached to divers, as they are less prone to entanglement.
  16. A backup cutting tool is recommended.
