The SSI Referral Diver program allows you to complete the academic and confined water (pool) sessions at one dive center, and complete your open water training dives at another destination. It's an excellent option if you want to do the theory and pool in your home town and complete the open water dives during your vacation. Once you successfully complete the theory and pool sessions, you will receive a referral document, valid for a limited time. You can then make your open water dives at any authorized SSI Dive Center in the world to earn your Open Water Diver certification. It's a flexible and convenient way to become a certified diver, especially if you're planning to travel to a tropical destination.
