SDI Master Scuba Diver Development Program
The SDI Master Scuba Diver is the highest rating in recreational diving before you step into the professional ranks. It's not awarded after a single weekend course. It's built on a body of work, a Rescue Diver certification, four completed specialty courses, and 50 logged dives, and it means something precisely because of that.
If you've already completed Rescue Diver and are working through your specialties, you may be closer than you think. Call us at (480) 881-4013 and we'll take a look at where you are and map out what's left.
The Three Requirements
The SDI Master Scuba Diver rating has three requirements, all three must be complete before the credential is issued.
SDI Rescue Diver Certification
You must hold a current SDI Rescue Diver certification or equivalent. If you haven't taken Rescue Diver yet, that's the next step before anything else. It's also the course most divers point to as the one that changed how they dive, so it's worth doing regardless of where you're headed after.
Four Completed SDI, TDI, or ERDI Specialty Courses
You need four full specialty certifications from the SDI, TDI, or ERDI catalog. These are complete certifications, not introductory dives. The specialties are yours to choose based on where you want to take your diving, Deep, Navigation, Underwater Photography, Drift, Boat, Intro to Tech, Search and Recovery, and many others qualify. For the full list of qualifying specialties we offer, please give us a call so we can discuss what is available.
50 Logged Dives
You need a minimum of 50 logged dives. All training dives count, including dives from your Open Water course, Advanced Adventure, Rescue Diver, and any specialty courses you've completed. If you've been diving consistently, this number builds faster than most people expect.
How to Get There from Here
The path to Master Scuba Diver looks different for every diver depending on where they're starting. A few common situations:
- If you have your Open Water card and nothing else, the path runs: Advanced Adventure, Rescue Diver, four full specialties, and 50 logged dives.
- If you've completed Advanced Adventure, each of those five specialty dives counts as one credit toward the corresponding full specialty certification. Finishing those out is one of the most efficient paths forward.
- If you already have Rescue Diver and some specialties, you may only need to finish a specialty or two and log a handful more dives.
The fastest way to figure out exactly what you need is to bring your logbook and your certification cards into the shop. We'll go through everything and tell you precisely what's left.
