How to pick a good dive
- Non-certified divers can try a 'discover scuba' dive with an instructor; certified divers should bring their card and logbook.
- Ask about the water temperature and the wetsuit thickness provided for that month.
- Leave 18 to 24 hours between your last dive and a flight.
- Check group size per guide; four to six divers per guide is a good sign.
