SDI – Scuba Diving International

SDI was founded in 1999 and grew out of TDI, the world’s largest technical diving organisation. SDI was founded on the idea that technology and knowledge are constantly changing and that diver teaching must change to reflect that. Although not as popular as PADI, in Thailand SDI is still quite common.

From the student’s perspective the main difference between SDI and PADI is that SDI students use a dive computer from the beginning and SDI emphasises in water training more, with less time spent on classroom theory. With SDI you also don’t have to purchase a manual, for the common courses you can borrow one.

All our SDI courses include the cost of equipment rental, log book and lunches when on the boat. If a course does not include a manual you may purchase the manual for an additional 1,500 THB. Everyone that completes a course get’s a free Castaway Diver’s t-shirt.

Castaway Divers Koh Lipe is a SDI Training Facility and offers online elearning courses. Contact us for more details.
