Scuba diving requires a minimum level of health and fitness. Chronic health conditions, certain medications and/or recent surgery may require you to get written approval from a physician before diving.
Avoid disappointment, download and review the Diver Medical form to ensure you won’t need a physician’s approval to dive before enrolling in a scuba course. Instructors, divemasters and dive shop staff are not physicians and should not be asked for medical advice; only medical professionals can give medical clearance to dive.
If you (or your physician) have questions about medical fitness to dive, contact the experts at Divers Alert Network (DAN).
You can complete this course locally or as part of a PADI® Professional program elsewhere.
Choose a dive shop close to home if you:
- Do most of your diving locally
- Want to support your local diving community
- Are enrolled in a professional-level course with your local dive shop
If you are enrolled in a professional-level course elsewhere, contact your dive shop before enrolling in Dive Theory eLearning online.
