In Zanzibar, I had a chance to see sharks for the first time ever, and will never forget it! Indian Ocean is beautiful, yet so different from any other place in the world, and Zanzibar is just one stop in this divers' paradise. There is a vast difference between low and high tide, and African wooden boats bring you to diving spots - an exotic trip, which is a memorable experience in itself! Lots of amazing places in Africa are still wild and intact for the simple reason that they are hard to access. Being the only diver in such a place gives a matchless thrill of discovery. It's worthwhile having a dip at the nearby Pemba Island as well.
Shortly about scuba diving training: Anyone can learn scuba diving, as no special physical preparedness is needed. There is nothing extreme about it, unless you venture to dive into caves or other risky underwater areas. Several schools in Latvia offer scuba diving training and issue internationally recognized certifications. The most widespread is PADI training system, which allows diving anyplace in the world, wherever you see PADI sign. The 1st level initial Open Waters Diver certification provides that you can dive to a maximum depth of 18m. The 2nd level Advanced Open Waters Diver certification allows extending ones maximum depth to 40m. A total of 5 dives must be completed for this purpose - 2 core dives comprise a deep and underwater navigation. And then you can choose 3 adventure dives - dive into a current, identify fishes, dive with a scooter, etc. There is a possibility to pass training and obtain a certification abroad too, at the same time getting the first glimpse of exotic underwater world there. Another option is to pass the first level in Latvia, and then continue elsewhere in the world - where visibility is better and water warmer. To be able to dive in very cold water using dry suit, you have to complete a Dry Suit Specialty training course as well.
