IANTD Limited Wreck Diver is represented on the current IANTD site by the Wreck Diver program, which focuses on developing wreck diving skills within the limits of light penetration. The official page emphasizes self-responsibility and risk management in overhead environments. That is the key point for this course: wrecks are interesting places to explore, but they require different thinking than ordinary open-water sightseeing.
The course fits divers who already have some post-entry-level experience and want a structured introduction to wreck procedures. IANTD lists prerequisites for Wreck Diver as Advanced Open Water Diver or equivalent, minimum age 15 for full diver qualification with parent or guardian authorization when needed, and proof of at least 10 logged dives. Junior Wreck Diver provisions are listed for qualified students between 12 and 14 who meet performance requirements and dive under appropriate adult supervision.
Training includes academic sessions, confined-water sessions, and wreck dive sessions using the IANTD Wreck Diver Student Kit. At Extreme Exposure in High Springs, Florida, the course should help divers understand wreck layout, hazards, line-of-sight limits, equipment awareness, team discipline, and the difference between limited wreck exposure and more advanced wreck penetration. It is a useful continuing-education step for divers who want to approach wreck environments with more respect and better preparation.
