Basic Wreck Diving (survey)

For bookings and more info, call the store:

Wreck Diving is a North East diving tradition. We are surrounded by one of the oldest shipping harbors in the US and there are enough wrecks in and around Boston harbor to prove it. Wreck diving tends to be an exhilarating and rewarding diving experience. With all of the excitement of swimming along a sunken shipwreck, they also tend to attract all manner of sea life. Unfortunately, there are also hazards that every wreck diver needs to know how to handle before descending down to the wreck. These hazards include things such as disorientation, loss of visibility, gas management, decompression hazards, and more. Learning skills such as line handling, slate use for mapping, identifying hazards, proper propulsion, and light management will help mitigate the risks of wreck diving and lay a foundation for more advanced wreck diving techniques. These skills will enable you to dive safely on wrecks all over the world.

After completing the Basic Wreck Course you may find yourself wanting to start entering into the wrecks you know are familiar with after the survey exercises. While the basic course teaches you to map out a wrecks points of interests and how to navigate around a wreck with line laying techniques there is still quite a bit to learn about penetrating into a wreck safely. That is where the Extended Range Wreck Diving course comes in. The Extended Range Wreck course picks up from the Basic Wreck course at penetrating inside the wreck. To enter into the Extended Range Wreck Diving course you need to have a foundation in an XR training program. For more information see the “Prerequisites” section of the Extended Range Wreck Diving course

During the course, you will learn how to properly plan your dive time and gas management to deal with dives that now have linear portions to them. You will learn how to lay and follow lines across and around the decks of shipwrecks and you will learn how to properly survey a wreck for your records and to prepare for wreck penetration.
