Wrecks can be explored from the outside with just an Open Water Diver certification. Most wrecks however lie in deeper waters where no-stop limits for recreational diving do not leave much time for exploration.

Technical diving certifications such as PSAI Advanced Nitrox are recommended for Wreck Penetration certification as most wreck penetration dives are decompression dives.

Penetrating wrecks without proper training is dangerous.

PSAI Advanced Wreck Penetration course teaches you the skills and procedures to enter wrecks.
