SSI Open Water Diver: How It Compares to PADI
SSI certifications are recognised worldwide alongside PADI, NAUI and BSAC. The training standards are broadly equivalent; the differences are administrative — SSI is free digital certification through a dive centre, with more flexibility in the order skills are taught.
Quick facts
- Minimum age
- 10 years
- Depth limit
- 18 m / 60 ft

What the certification covers
- Free digital learning materials through the SSI app
- Confined water skill development in flexible order
- Four open water training dives

Which agency should you pick?
In practice the instructor matters far more than the logo. Every major agency meets the same ISO and WRSTC standards, and no operator anywhere will turn away an SSI card.
Choose based on the centre: how many students per instructor, whether they dive locally after the course, and whether they run a club you can keep diving with.
- SSI digital certification is free; PADI charges for physical cards
- SSI ties certification to a centre; PADI instructors can teach independently
- Both are accepted for onward training at the other agency
