Level up your skills with our Diving Specialties!
Expand your diving skills with our Specialty Courses in Cozumel! From Night Diving to Nitrox, explore new adventures and earn certifications.

What's the goal of learning a Diving Specialty?
During your scuba diving certification, you’ve learnt a lot. But you’ll soon realize that there’s much more to learn when you want to become an experienced scuba diver.
Because diving is an activity that can be done in an infinity of different conditions, there’s a wide range of additional skills you might want to learn: night diving, drift diving, deep diving… Just to name a few.
At Deep Blue Cozumel, we offer Specialties for both SSI and PADI diving agencies.
Note that you do not need to own a SSI certification to complete a SSI Specialty (and vice versa with PADI).

What's included
- One specialty to select from our many options

Fantastic people, Fantastic shop, Fantastic experience.
Fantastic shop. Debbie (owner) Gigi, Jules, and Kristian were all awesome to work with. Bilingual, so making arrangements was a breeze. It had been a few years since my last dive, so I took the mini refresher course, which was well worth it. Prices for the dives are very reasonable. Super friendly, communicative, & informative. I will definitely book with them again.

one of the smoothest best organized dive trips I have ever done
My partner and I did a 2 tank dive and a night dive. It was one of the smoothest best organized dive trips I have ever done. The staff was incredible, helpful, kind, knowledgeable through and through from the dive shop to the boat, Gigi and Lorena in particular. They provided us with great equipment, giving us advice and making sure it all fit well, on the boat changeover of tanks and moving from dive site to dive site was seamless. We had such a great time diving with Deep Blue.

Fantastic dive service!
Fantastic dive service! Got my advanced cert with Julio over summer, very effective teacher and even showed some really handy and cool buoyancy tricks you won't see in the PADI learning. The reefs are incredible too, you'd have to see them to believe them. I can see why people flock to this island of paradise for diving. Did a couple night dives as well, those were seriously out of this world.

My 14 year old daughter felt comfortable the entire time and had an experience she'll never forget.
Everything about my experience was great! Their excellent, clear and quick communication grabbed my attention at the start. All of the employees were so nice and the booking went smoothly beginning to end. We had Gigi as our discovery dive instructor and she was absolutely amazing! I felt so lucky to have had her. My 14 year old daughter felt comfortable the entire time and had an experience she'll never forget. The reef diving was top notch and we saw just about everything from a shark to a squid to an eel. If I make it to Cozumel again, I will 100% return to Deep Blue.

I can only recommend diving with deep blue
Iām a beginner and did the discovery dive with Juls and it was an amazing experience! The reef is just so beautiful, I havenāt seen anything comparable before. Juls is a great instructor, I felt safe and comfortable at all times and thanks to him I saw my very first sea turtle :) I can only recommend diving with deep blue.
