About Deep Exposure Dive Center
Deep Exposure Dive Center runs boat diving from a shop two blocks in from San Miguel de Cozumel's waterfront, inside the island's national marine park. Its two boats, Deep Exposure I and Deep Exposure II, carry a DAN oxygen kit, GPS and sonar, and make just one outing a day, with no second group waiting for a turnaround. Regulars and critics describe the same shape from opposite sides: surface intervals run long and dives are not cut short, with reports of dives past 80 minutes against the 50-minute ascent calls made on other Cozumel charters, and the boat back at the pier in the afternoon, not at midday.
Training is built around technical diving. The shop publishes the full TDI ladder from an introductory technical course through hypoxic trimix, teaches closed-circuit rebreather courses on three unit types, and blends its own gas on site, selling Sofnolime by the 44-pound keg, not the bottle. Every divemaster on staff holds at minimum an Open Water Instructor certification, a standard applied to a first Discover Scuba dive as much as to a trimix class. Recreational training runs a PADI and SDI open-water ladder alongside a separate NAUI progression through Rescue Diver. Guided technical dives, private charters, a Cozumel cave tour and mainland cavern and cenote day trips round out what leaves the dock, on top of the standard one, two and three-tank reef trips.
What divers say
Named staff recur across independent Google and TripAdvisor reviews from 2023 to 2026, written by people who never dived together: Arturo for teaching and lending out a fish identification book, Roger for guiding and humour, Gabo for patience, Pancho for boat handling and cooking, and Captain Giovanni. The same two platforms separately describe small boat loads, food kept on board and gear stored between dive days, plus flexibility such as taking on a stranded group at a day's notice or letting an injured diver dive without a BCD.
Complaints cluster around one mechanism, not a single incident. Putting a technical diver and an open-water-only group on the same boat leaves the technical diver's day set by the least experienced person aboard, a pattern several experienced divers describe independently and call the shop's most common friction point. Away from that, the one below-five-star account among the reviews read for this page describes a single dive where a guide's attention lapsed badly enough that the reviewer cancelled the rest of the booking; it reads as one isolated case, with nothing similar in the record.

Frequently Asked Questions
Can you do technical or trimix diving in Cozumel?▾
Yes. Deep Exposure publishes the full TDI ladder from an introductory technical course through hypoxic trimix, with closed-circuit rebreather instruction on three unit types and its own gas blending and Sofnolime on site. Guided technical dives to 200 or 300 feet are sold separately from the course ladder, alongside private technical charters.
Where can a rebreather diver get absorbent and gas fills on Cozumel?▾
Deep Exposure blends its own nitrox and stocks Sofnolime by the keg, alongside daily CCR rental that includes oxygen, diluent and onboard tanks. A rebreather diver reported a few years ago that this was the only shop on the island carrying absorbent, 3-litre bottles and boosted oxygen; the equipment itself is still on the current price list, though nothing more recent confirms whether it remains the only source.
What happens if recreational and technical divers share the boat here?▾
It happens routinely: the shop runs one outing a day and does not turn the boat around for a second group. Regulars describe it as usually working by mutual consent, with a smaller boat available for a separate group when needed. Divers who say it has not worked for them describe a single mixed boat setting the whole day's profile to the least experienced diver aboard, with no relief short of a dedicated technical trip or a paid private guide. It is a scheduling fit question worth asking about when booking, not a quality problem.
What time does the boat get back?▾
The shop publishes shop-counter hours, split around a midday break, but no boat departure or return time. Divers have described afternoon returns from the single daily outing: the cost of the unhurried surface intervals and long dives a single trip a day allows.
Can you dive a cenote or cave without going to the mainland?▾
Yes, on Cozumel itself: a one-dive cave tour is sold locally, doubles included. Cave and cavern day trips to the mainland cenotes are also on the rate card, and a customer has separately confirmed doing one.
Does the shop blend its own nitrox?▾
EAN32 and EAN36 fills are priced per tank on the rate card, and the shop also runs a one-day Basic Nitrox Diver course. A customer who toured the fill station has described custom blends made to order.
What's included in a boat trip here?▾
Hotel pier pickup, gear handled for you, food and drinks, a freshwater shower, tank rinse and a camera table, on either of the shop's two boats. Guided dives run one, two or three tanks, with reef and night options.
