THE SDI-ERDI FULL FACE MASK DIVER MANUAL IS THE TEXT-BOOK LITERARY ASSISTANT TO THE SDI AND ERDI FULL FACE MASK DIVER CERTIFICATION COURSES.
Divers often have a need or want to effectively communicate underwater. The SDI Full Face Mask Course is the perfect starting point. Full face mask diving allows the diver to relax and enjoy diving while not worrying about maintaining the second stage regulator. In addition, the full face mask will help insulate the diver from a coldwater environment.
Using the Full Face Mask Diver Manual as a reference, students may utilize the Knowledge Quest Work Booklet by answering the provided questions with the most appropriate and accurate answers.
The Knowledge Quest is designed to be used as an assessment for enrolled students and their respective instructors.
