Open Water Diver

The SEI Diving Open Water Diver course is for individuals ages 12 and older.  Learning to scuba dive is safe and affordable, and requires a modest amount of training.  In order to earn a scuba certification, you will participate in classroom sessions, practice essential diving skills in a pool and experience several open water dives.  Divers between 12 - 15 years of age will be certified as Junior Open Water Divers.


Open Water Plus Diver

SEI Diving's Open Water Diver course is designed to give certified scuba divers two additional open water dives. This guided experience is important for new divers who want more training before going out and diving without supervision.

Advanced Plus Open Water Diver

This course includes additional classroom training and adds ten additional dives to the diver's experience. Open water diving is the primary objective of this course with classroom training designed to augment the knowledge presented to Open Water divers.



Master Scuba Diver

This course and certification is the highest and most prestigious non-leadership rating that may be attained by an SEI Diving diver. It is considered the supreme standard of diving excellence and recognition of expert training. This course of instruction is often offered to students over a period of time rather than in a formal class environment. In this way, students can build knowledge and skills while meeting all the completion requirements including other specialty courses.
