SSI certification - recognized worldwide
Your SSI Open Water Diver card is internationally recognized and never expires. Once certified, you can dive with any operator around the world, up to 18 meters (60 feet), with a buddy of equivalent level.
Be Water Diving is an official SSI certified dive center based in Tamarindo, Costa Rica. All our instructors are fully SSI-qualified, bilingual, and trained to the latest standards, so your certification is in good hands from day one.
HOW IT WORKS
What happens over the 3 days
You start with the theory portion, covering the basic principles of diving, safety procedures, and equipment. Then you move into confined water (pool session) to practice your skills in a controlled environment. Your instructor walks you through everything step by step before you ever go into open water.
Time to put everything into practice in real conditions. You board our boat in Tamarindo and head out to the Catalina Islands for your first two open water dives. Your instructor stays with you throughout, helping you build confidence and get comfortable underwater.
Two more dives at the Catalinas to refine your skills and demonstrate your proficiency. Once completed, you receive your SSI Open Water Diver certification, and you're officially a certified diver, ready to explore the underwater world anywhere.

WHAT IS A SSI OPEN WATER DIVER COURSE?
Your first step into the diving world
The SSI Open Water Diver certification is the standard entry-level scuba diving certification, recognized worldwide. Once you have it, you can dive independently with a buddy anywhere in the world, up to 18 meters.
The course covers everything from the basics of how diving works to real open water dives at the Catalina Islands. You don’t need any prior experience, just be at least 10 years old, in good health, and comfortable in the water.
We keep our groups small, maximum 3 students per instructor, so you get proper attention throughout, not just a quick certification factory experience.
