Overview
The SDI Wreck Limited Penetration Diver course develops the knowledge and practical skills required to safely conduct limited penetrations into wreck structures.
Unlike external wreck exploration, limited penetration diving introduces additional considerations including overhead environments, line procedures, navigation challenges, emergency planning, and environmental awareness.
Training focuses on:
- limited penetration procedures,
- overhead environment awareness,
- guideline use,
- wreck navigation,
- emergency planning,
- and risk management.
At N9BO℠, Wreck Limited Penetration Diver training develops the discipline and situational awareness required to safely explore designated wreck interior areas while remaining within recreational diving limits.
