Frequently Asked Questions: SSI vs RAID

What’s the main difference between SSI and RAID certifications?
The primary difference lies in specialization and depth limits. SSI offers broad recreational diving education with 18-meter Open Water certification and extensive global accessibility. RAID provides 20-meter Open Water certification with specialized focus on technical and rebreather diving, appealing to divers seeking advanced training opportunities.
Does the 2-meter depth difference between SSI and RAID matter?
Yes, the additional 2 meters (20m vs 18m) can be significant. Many popular dive sites have features at 19-20 meters depth, meaning RAID-certified divers can access more underwater attractions immediately after certification. This extra depth often provides access to better marine life encounters and dive site features.

Both certifications are globally recognized, but SSI has broader immediate recognition due to its larger network of 3,300+ training centers. RAID’s recognition is rapidly growing, especially among technical diving communities. Most dive operators worldwide accept both certifications without issue.
Can I switch from SSI to RAID or vice versa during training?

The process may involve additional time and costs, so it’s best to choose your preferred agency before starting training. Discuss options with dive centers offering both certifications.

Both agencies excel at beginner training but with different approaches. SSI’s flexible digital learning and personalized instruction suit many beginners, while RAID’s comprehensive, precision-focused training appeals to those wanting rigorous education. The choice depends on your learning style and diving goals rather than experience level. Consider researching quality dive centers that offer both options.
Do SSI and RAID courses take the same amount of time to complete?
Both agencies typically offer 4-day Open Water courses, but the structure differs. SSI emphasizes flexible, self-paced learning with digital materials, while RAID focuses on intensive, comprehensive training sessions.
