The Sea Dwellers Advantage:

Since 1972, Sea Dwellers Dive Center has consistently provided safe, reliable and fun-filled scuba adventures in the Florida Keys. We’ve earned the reputation as “The name you know and trust.” for diving not just in Key Largo, but in Southern Florida and all of the Florida Keys. What’s behind our success? We are a small, boutique style dive center & finest independent dive operator. We treat you like a friend, and this is shown in our large number of repeat guests. Don't believe us, check out our Hall of Fame page!

We are here for YOU
  • Your safety is our #1 concern. Your comfort and enjoyment are our #1.1 concern. 
  • It’s your vacation, dive at your own pace. We offer over an hour of "pool's open" time at each dive location.
  • We do all the hard work and heavy lifting. All you have to do is show up and enjoy! We offer 5 star concierge service with rental gear, you bring it from the shop to the boat, and we bring the heavy, wet, used gear back to clean and sanitize it while you stroll off to your next activity. 
  • No cattle boats here! Our larger boat can hold 50 passengers but we limit it to 28 maximum! We would rather take out fewer guests and let them have a more enjoyable time over stuffing as many people as possible on just to make an extra buck. Plus it's HOT down here, we don't want to make it worse with a PACKED boat.
  • We have hands down the BEST crew of Captains, Divemasters, Instructors and Operations Staff around. Check out our reviews on Google and TripAdvisor!
  • Our full-service dive center and boats are about a 2 minute walk from the 3 most popular hotels on the canal!
  • Our staff are all very experienced, professional, fun, friendly, approachable and helpful. We don't hire Interns, Newbies, or Jerks. 
  • Our well trained crews are so on top of things, they often spot trouble before it becomes trouble and intervene before anyone knows that a situation was about to happen. 
  • Each boat is fully stocked with an Emergency Oxygen Kit, First Aid Kit, AED, Firefighting Equipment, Rescue Equipment and Communications/Navigation Equipment. Our crews train regularly under the watchful eye of our local Coast Guard Sector in a variety of areas to keep their skills razor sharp. We are ready, trained and reactive regardless of the situation.
