Diving Tips for Beginners
- Get Open Water certified before your trip through PADI or SSI — most destinations require proof of certification for anything beyond a shallow introductory dive.
- Book with reputable, well-reviewed dive operators — safety standards vary significantly by region.
- Consider travel insurance with diving coverage, since standard policies often exclude scuba-related injuries.
