The UTD Wreck Penetration 2 course is the next step in the wreck penetration series of classes. The Wreck Penetration 2 course is designed to prepare you for more advanced wreck dives utilizing a maximum of two bottles (either two deco bottles or a single stage bottle + one deco bottle) in addition to back gas to penetrate wrecks, opening the way for longer penetration times and access to deeper wrecks. Students will expand their knowledge of gas management by adding these additional bottles with the use of doubles, laying and retrieving guideline, following the line, and become familiar with the failures associated with wreck penetration. The failures will expand on what was learned in the UTD Wreck Penetration 1 course. All protocols and procedures are derived from the UTD overhead environment procedures and are applied to wreck diving. This class provides an excellent foundation to build wreck diving experience and prepare for the challenges found during the UTD Wreck Penetration 3 course.

Once you have been inside a wreck it is obvious to most divers that being able to explore the wreck further is critical. Being able to explore the engine room of your favorite wreck is something few people get to do. Often forgotten is that by pushing the distance of penetration in the overhead, the risk is also increased which is why you need to be properly trained.

The UTD Wreck Penetration 2 course is normally conducted over a five day period following the UTD Wreck Penetration 1 course. UTD Wreck Penetration 2 may not be combined with any other class. It involves a minimum of 40 hours of instruction to include classroom, dry runs, and in-water work.
