PSAI Advanced Wreck Penetration
PSAI Advanced Wreck Penetration is one of our most popular technical diving courses. It is also one of the most challenging. As wreck penetration involves diving in tight, confined spaces in an overhead environment, your dive skills - especially buoyancy control - must be impeccable.
PSAI ADVANCED WRECK PENETRATION PROGRAMS
Required Prerequisite Certifications
PSAI Advanced Open Water Diver
PSAI Advanced Buoyancy Control (ABC)
PSAI Deep Sport Diver
PSAI Basic Underwater Navigation
PSAI Overhead Environment Specialties
PSAI Overhead Environment Sidemount Diver
PSAI Overhead Environment Diver Propulsion Vehicle Diver
PSAI Underwater Cave Survey and Cartography
Minimum age: 18 years old.
Certifications: PSAI Advanced Open Water, PSAI Advanced Buoyancy Control and PSAI Sport Wreck Diver* or equivalent certifications from a recognized dive agency.
PSAI Advanced Nitrox or equivalent recommended.**
Minimum of seventy (70) logged dives prior to entry to the course with at least twenty (20) logged dives deeper than 18 meters (60 feet). Twin set experience recommended.
*) If you don't have a recreational Wreck Diver Specialty rating, you can earn it in conjunction with the PSAI Advanced Wreck course.
**) Most wreck penetration dives are planned as decompression dives. While there are wrecks shallow enough to allow penetration within no-stop limits, most wrecks are in deeper waters, where no-stop limits don't leave much time for actual exploration.

What you do
We'll first get your dive skills up to the level appropriate for wreck penetration. If you haven't done the ABC program, that is where you'll start. We'll do line drills both on land and underwater - day time and night time. For those we have perfect dive sites in Hong Kong. You'll also complete most of the academic study. Once you're ready, we'll go and do the actual wreck penetration dives: most common destinations are Subic Bay or Coron in the Philippines.
Approximately 20-25 hours for classroom and practical demonstrations:
these are done mostly at dive sites before and after dives.
Confined water (pool) sessions as needed
Minimum of six (6) wreck penetration dives
PSAI Advanced Wreck Penetration-Overhead Diver manual (and PSAI Wreck Sports Diver manual if you have not completed a recreational Wreck Diver Specialty).
Standard technical diving equipment appropriate for the environment of the wreck dive.
Cylinders with dual outlet manifold or manifold “doubles”. Two (2) independent first and second stage regulators, one (1) with a long hose. Cylinder outlets and regulator to manifold attachments are to be DIN.
Penetration equipment including
- Primary and two (2) secondary lights
- Redundancy for buoyancy – Dual bladder BCDs recommended
- Reels and directional markers
- At least two line cutting devices
- Surface Marker Buoy(s) with reel/ascent line
- Decompression lines and appropriate aids for the specific wreck environment
- Safety cylinder(s) to be tied off on descent/ascent line
- Slate, pencil and compass
- All equipment must meet the minimums defined in the PSAI Advanced Wreck Penetration - Overhead Manual.
Wreck diving requires impeccable buoyancy control.
Diving in a wreck is diving into history. You'll see tools and equipment covered by marine life, but untouched for decades.
The Advanced Wreck Penetration course is designed for scuba divers who wish to penetrate wrecks using proper techniques. These penetrations are not simple swim-throughs, but multi-level or multiturn dives. The dive team will always maintain a continuous guideline leading to the exit while in the wreck overhead environment.
What you learn
You'll learn to plan and conduct penetration wreck dives in environments and conditions similar to your training, with the gases you are qualified to use and within depths of your current certification.
This course provides the necessary information for the diver to know the proper procedures to:
Determine appropriate gas for planned dives.
Determine appropriate diving equipment for planned Wreck Penetration dives.
Plan dives based in established limits and cautions for gas supply, type of gas and penetration objectives.
Properly establish guideline(s) in the overhead wreck environment.
Understand and explain the hazards associated with penetration wreck diving.
